Soudal Fix ALL Crystal Clear - Foil Pack

Health & Safety Recommendations

Observe normal site hygiene and safe working practices throughout. Read the packaging label and Safety Data Sheet before use to understand handling precautions, first aid measures, and any site-specific controls. Wear suitable gloves and eye protection, and avoid prolonged skin contact. Keep the work area well ventilated during application and throughout curing, especially in smaller rooms such as bathrooms, cloakrooms, or utility spaces where vapours and cleaning solvents can linger.

Keep the product away from children, animals, and food preparation areas during use. If applying in occupied environments, prevent access to freshly applied joints until the sealant has skinned and is protected from disturbance. In the event of contact with eyes or skin, wash immediately with plenty of clean water and seek medical advice if symptoms persist.

Substrate Suitability

Soudal Fix ALL Crystal is designed for bonding and sealing on a wide range of common building materials, including glass, lacquered wood, PVC, metals, brickwork, concrete, and many typical construction substrates. Its SMX Hybrid Polymer base provides a strong, elastic bond for general building sealing, sanitary joints, and transparent bonding where appearance is critical.

The product is not suitable for polyethylene (PE), polypropylene (PP), PTFE (Teflon®), bituminous substrates, or copper and copper-containing materials such as bronze and brass. In addition, bonding certain plastics such as PMMA (Plexi® glass) and polycarbonate (Makrolon® or Lexan®) in stress-loaded applications can cause stress cracking or crazing, so Fix ALL Crystal is not recommended in those situations. Due to variations in plastics and coated finishes between manufacturers, carry out an adhesion and compatibility test on every new substrate combination before proceeding with full application.

Surface Preparation

Correct preparation is essential for a reliable clear seal and a strong long-term bond. Substrates must be rigid, clean, and structurally sound. Remove dust, grease, loose coatings, release agents, and any residues that could interfere with adhesion. Surfaces should be dry or only slightly moist, with no standing water present. If working in kitchens and bathrooms, remove soap deposits and limescale fully, as these contaminants commonly cause edge lifting and joint failure regardless of sealant quality.

Porous substrates benefit from priming to stabilise the surface and improve adhesion. Prime porous surfaces using Soudal Primer 150 in accordance with the primer instructions. Non-porous surfaces can be prepared using Soudal Cleaner & Degreaser to remove oils and improve surface wetting. Plastics often carry processing aids, protective films, or release agents from manufacturing, so remove protective foils and clean thoroughly before bonding or sealing, as these invisible residues are a common cause of poor adhesion.

Application Method

Soudal Fix ALL Crystal can be applied for sealing joints or for bonding components. For 600ml foil packs, use the Soudal 600ml Manual Foil Cartridge Gun, ensure the foil pack is seated correctly, and cut the nozzle to suit the required bead size. Work methodically and avoid contaminating the nozzle tip with dust or debris, as this can drag through the bead and affect clarity.

For sealing, apply the product evenly into the joint with steady pressure to avoid air inclusions. Ensure the bead makes full contact with both joint flanks and forms a continuous seal. Tool the joint immediately before skin formation using a suitable spatula and a finishing solution to achieve a neat profile. Prevent finishing solution contacting the adhesion faces between the sealant and joint edges, as this can reduce adhesion and lead to premature failure, especially in wet areas.

For bonding, apply the adhesive in beads or dots to one substrate. Place additional beads along edges and at corners of panels to improve wetting and reduce the risk of unbonded areas. Bring the parts together before skin formation and press firmly. The applied pressure is more important than the duration of pressure, so ensure the bond line is fully compressed and properly seated. Where the assembly could creep or slip, provide temporary support or bracing until the bond has developed sufficient strength. Tap down gently with a rubber mallet where appropriate to improve contact without damaging the substrates.

Joint Dimensions

Joint sizing has a direct effect on appearance, durability, and the final movement capability.

For sealing joints, the minimum joint width is 5mm and the maximum joint width is 10mm, with a minimum joint depth of 5mm. These limits reflect the product’s intended use as a clear elastic sealant for neat finishing rather than large movement expansion joint detailing.

For bonding applications where Fix ALL Crystal is used as a thin, transparent bond line, the recommended bond thickness range is typically 1mm to 3mm. Keeping the bond line within this range supports good curing behaviour, a cleaner transparent finish, and more predictable strength build-up.

Avoid using the product as a glazing sealant or in joint designs that require specialist glazing performance.

Coverage

Coverage depends entirely on bead size and joint geometry. A narrow sealing bead may achieve a long linear run, while larger beads used for bonding or making good will reduce the total linear metres achievable. For practical estimating, use the Platinum Chemicals Sealant Estimate Calculator to calculate approximate coverage based on joint width and depth, and allow an additional margin for start-stop losses, tooling, and occasional over-application.

Where a uniform visual finish is important, plan the job to maintain a consistent bead size and keep nozzle cuts consistent across the project. This not only improves appearance but helps ordering accuracy, especially on multiple-room sealing work such as bathrooms, kitchens, and internal finishing.

Curing Time

Fix ALL Crystal cures by moisture curing. Under typical site conditions it forms a skin in approximately 4min, so tooling should be completed immediately after application. Curing progresses at approximately 2mm/24h to 3mm/24h, depending on temperature, humidity, airflow, bead thickness, and substrate type. Thicker beads and cooler, drier conditions slow curing, while warmer, well-ventilated environments generally accelerate it.

Avoid disturbing joints during the skinning phase, as early movement can tear the surface and compromise the seal. Protect freshly applied joints from dust and water splash during early curing. Where overpainting is planned, allow the sealant to cure sufficiently first. Fix ALL Crystal is paintable with many water based paints, but alkyd resin based paints can show increased drying times. Due to the wide variation in paint formulations, carry out a compatibility test before full decoration.

Cleaning

Clean excess material immediately while uncured. Use Soudal Swipex Wipes to remove fresh product from tools and non-porous surfaces, taking care not to smear sealant across adjacent finishes. If masking tape has been used, remove it promptly after tooling, before skin formation, to avoid tearing edges and leaving ragged lines.

Once cured, Fix ALL Crystal can only be removed mechanically. Use Soudal Sealant Remover Spray as a support product where appropriate, then lift and scrape carefully to avoid damaging the substrate. On sensitive surfaces, test any cleaner or remover in an inconspicuous area first.

Limitations

Fix ALL Crystal is not suitable for PE, PP, PTFE, bituminous substrates, or copper and copper-containing materials such as bronze and brass. It is not recommended for stress-loaded bonding on PMMA or polycarbonate due to the risk of stress cracking and crazing. For polycarbonate, use Silirub PC. Fix ALL Crystal is not suitable for self-cleaning glass, use Soudal SMX 506 where a compatible solution is required.

Do not use Fix ALL Crystal as a glazing sealant, use Silirub 2 or Silirub LMN. It is not suitable for bonding aquariums, use Silirub AQ. The product is not suitable for expansion joints and should not be used where continuous water immersion is possible. In sanitary environments, mould resistance supports joint durability, but it does not replace normal cleaning. Heavy contamination, deposits, and soap residues encourage fungal growth on any sealant surface over time.

Colour change can occur in the absence of UV, and discolouration may occur due to chemical exposure, elevated temperatures, or prolonged UV radiation. The product can discolour under extreme conditions or after very long UV exposure. Avoid contact with bitumen, tar, and plasticiser-releasing materials such as EPDM, neoprene, and butyl, as these can cause discolouration and adhesion loss. For EPDM applications, use Silirub EPDM. For bitumen, use Soudal Soudafalt.

Other Information

Fix ALL Crystal aligns with low-emission requirements referenced under LEED Low-Emitting Materials, including SCAQMD Rule 1168 and USGBC LEED 2009 Credit 4.1 expectations for adhesives and sealants, which can be valuable where indoor air quality and specification compliance are important. Store the product as directed on the packaging, keep cartridges and foil packs sealed until use, and avoid exposing unopened packs to extremes of temperature.

Where different reactive sealants are required in the same area, allow the first product to cure fully before applying the next. This reduces the risk of incompatibility and surface inhibition. For the best visible finish on clear joints, maintain consistent bead sizing, tool promptly, and prevent finishing solution from contaminating adhesion edges, as this is one of the most common causes of clear-joint failure in bathrooms, kitchens, and internal finishing work.

Q) What is Soudal Fix ALL Crystal Foil Packs and what is it designed for?

A) Soudal Fix ALL Crystal Foil Packs is a premium, crystal clear, neutral cure SMX Hybrid Polymer adhesive sealant supplied in 600ml foil packs. It is designed for high output bonding, sealing and filling where the finished joint needs to look discreet rather than leaving a visible bead line. Once cured, it stays permanently elastic and accommodates movement up to ±20%, which helps the seal remain watertight and reliable as materials expand, contract and settle. It also contains XS1 fungicides for mould resistance in kitchens and bathrooms, and it is virtually odourless, which makes it a sensible choice for sensitive indoor environments.

Q) What is the advantage of the foil pack format compared with standard cartridges?

A) The biggest advantage is efficiency. A 600ml foil pack holds more product than a standard cartridge, so you get longer continuous runs, fewer reloads, and better consistency on visible joints. The foil format can also reduce packaging waste by up to 95%, which means less rigid plastic to dispose of and far less residual product trapped in the pack. That matters when you are sealing multiple rooms or running long perimeter beads, because waste and stoppages add up quickly. Foil packs also suit professional use because the application feels smoother and more continuous when paired with the correct applicator.

Q) When should I choose Soudal Fix ALL Crystal Foil Packs over a coloured sealant?

A) Choose it when appearance matters as much as performance. Soudal Fix ALL Crystal Foil Packs cures genuinely transparent, so it is ideal on glass, glazed tiles, coated trims, decorative surfaces and modern interiors where a white or coloured line would stand out. It is also useful where you want a flexible, watertight seal without the look of silicone, especially in bathrooms and kitchens. Because it is an adhesive sealant, it can also be used for discreet bonding as well as sealing, which reduces the need to swap products mid job. If you need a paintable finish, it can be painted with many water based systems after curing.

Q) What are the most common uses people have for this product at home and on site?

A) Common uses include clear sanitary sealing around baths, basins, shower trays and tiled junctions, plus sealing splashbacks and worktop interfaces where you want a neat, hygienic finish without a strong contrast line. It is also used for interior trim sealing around skirtings, architraves and decorative profiles where a clear joint looks cleaner. As an adhesive, it suits discreet bonding of compatible materials for small repairs, trim fitting and tidy finishing work. Outdoors, it can seal compatible junctions where a clear finish is preferred, as long as the joint is not designed for continuous water immersion.

Q) Is Soudal Fix ALL Crystal Foil Packs suitable for bathrooms and does it resist mould?

A) Yes. Soudal Fix ALL Crystal Foil Packs includes XS1 fungicides which help resist mould growth on the sealant surface, making it suitable for bathrooms, showers and kitchens where humidity and condensation are routine. It is particularly useful where you want a clear joint line that does not distract from tiles, glass or sanitaryware. For best mould resistance, preparation and detailing matter. Remove old sealant fully, clean away limescale and soap residue, and tool the bead to a smooth profile so water sheds rather than sitting on the joint. Good ventilation and normal cleaning are still important, because contamination can feed mould on any sealant over time.

Q) Can Soudal Fix ALL Crystal Foil Packs be used outside and in poor weather?

A) It is designed for internal and external use and can be applied in all weather conditions, including on many slightly damp or humid surfaces. That makes it practical for repairs and external detailing where waiting for perfect dry conditions is unrealistic. Once cured, it remains elastic and stable across typical building temperature swings, with service performance stated from -40°C to +90°C. You still need sensible site control. Apply within +5°C to +35°C for consistent gunning and cure, and protect fresh work from rain wash off before skin formation. Avoid using it where the joint will be permanently submerged or continually water loaded.

Q) Will it adhere properly to slightly damp or humid surfaces?

A) Soudal Fix ALL Crystal Foil Packs is formulated to bond to many damp or slightly moist surfaces, which is a major advantage for maintenance and refurbishment work. The key is that damp must not mean dirty. Remove standing water, dust, grease, soap films, loose paint and old sealant residues so the product can wet out and grip the substrate properly. Damp dust and invisible residue are common causes of edge lift and bond failure, especially in bathrooms and kitchens. If the surface is porous and weak or chalky, stabilise it first and consider priming with Soudal Primer 150. Always do a small adhesion test on unfamiliar finishes.

Q) What surfaces does it bond to without primer in most cases?

A) It typically bonds well without primer to many common construction substrates, including glass, glazed tiles, metals, lacquered wood, masonry and a wide range of stable building materials used in fit out and maintenance. Neutral cure behaviour helps with broad compatibility, especially where mixed materials meet. Primerless does not mean prep free, so keep joint edges clean, dry to the touch or only slightly moist, and free from release agents and oils. On critical joints, powder coated finishes, unusual plastics, or unknown paint systems, a small adhesion and compatibility test is sensible. Where porous substrates are dusty or very absorbent, priming with Soudal Primer 150 improves reliability.

Q) Which materials should I avoid using Soudal Fix ALL Crystal Foil Packs on?

A) Avoid low surface energy plastics such as PE, PP and PTFE (Teflon®), because reliable adhesion is not expected. It is also not suitable for bituminous substrates or copper and copper containing materials such as bronze and brass. Be cautious on plastics under stress. Stress loaded bonding on PMMA (Plexi® glass) and polycarbonate (Makrolon® or Lexan®) can lead to stress cracking and crazing, so it is not recommended for those situations. Where polycarbonate sealing is required, use Silirub PC. Avoid contact with EPDM and other plasticiser releasing materials such as neoprene and butyl, because discolouration and adhesion loss can occur, so use Silirub EPDM where EPDM is involved.

Q) How should I prepare surfaces for the best clear finish and strongest bond?

A) Preparation is crucial because clear products make flaws more obvious. Joint edges must be rigid, sound and free from dust, grease, soap residue, loose paint and old sealant. In bathrooms, remove all traces of previous silicone and clean away limescale, because contamination at the edges is the usual reason joints fail early. On non porous surfaces, clean and degrease using Soudal Cleaner & Degreaser and allow it to flash off fully before sealing. On porous, dusty or chalky substrates, prime using Soudal Primer 150 to stabilise the surface and support consistent adhesion. Mask both sides of the joint if you want sharp lines, then remove tape immediately after tooling.

Q) What is the correct way to apply Soudal Fix ALL Crystal Foil Packs as a sealant?

A) Use the correct applicator, such as the Soudal 600ml Manual Foil Cartridge Gun, and cut the nozzle to suit the bead size so you can maintain consistent flow. Apply a continuous bead with steady pressure, ensuring the sealant wets both sides of the joint and is not dragged across the surface. Tool immediately to compact the bead and form a smooth profile, because this product skins quickly at around four minutes under typical conditions. Keep finishing liquids away from the adhesion faces, as contamination can lead to edge lift later. Remove masking tape straight after tooling while the sealant is still fresh, then protect the joint from disturbance while it skins and begins curing.

Q) How do I use Soudal Fix ALL Crystal Foil Packs as an adhesive for invisible bonding?

A) Apply the adhesive in beads or dots to one substrate, paying attention to edges and corners where peel stress is highest, then bring the parts together before skin formation begins. Press firmly to achieve good wet out, because bond quality depends more on contact pressure than on how long you hold it. For panels or trims, a continuous perimeter bead improves stability and reduces the chance of visible gaps. Support heavy or awkward items until curing has progressed, especially where gravity could cause creep. Keep bond lines controlled and avoid very thick blobs, because deep sections cure more slowly and can trap air. On high finish work, test a small area first to confirm the clarity and appearance.

Q) What joint sizes are recommended for sealing and for bonding gaps?

A) For sealing, keep joint geometry sensible so the product cures properly and performs elastically. A minimum joint width of 5mm and a minimum depth of 5mm is a good baseline, with a maximum sealing width of 10mm for best control and appearance on clear joints. For bonding gaps, aim for a tighter bond line, typically 1mm to 3mm, because controlled thickness gives more predictable curing and a cleaner transparent finish. This product is not intended for large expansion joints, so do not use it where the detail is designed for high structural movement. If you need a dedicated movement joint sealant for façades or glazing systems, use Silirub 2 or Silirub LMN as appropriate.

Q) How flexible is it once cured and what movement can it handle?

A) Soudal Fix ALL Crystal Foil Packs cures to a permanently elastic rubber that accommodates movement up to ±20% when the joint is correctly designed and applied. That makes it suitable for many everyday building joints where materials shift slightly with temperature changes, vibration and minor settlement. The cured bead is robust enough for routine cleaning while still remaining compliant, so it is well suited to sanitary sealing, interior finishing and general maintenance. It is not an expansion joint product, so it should not be specified where large structural movement is expected. If the joint is likely to experience higher movement, choose a silicone designed for that role, such as Silirub 2 or Silirub LMN, rather than forcing a hybrid into the wrong detail.

Q) How long does it take to skin and cure, and when can the joint be used?

A) Skin formation is typically around four minutes, so plan your work in short, manageable lengths that you can tool immediately. Curing then progresses at roughly 2mm to 3mm per twenty four hours, with the exact rate affected by temperature, humidity, airflow and bead thickness. Deep beads cure more slowly, so allow extra time before exposing the joint to heavy cleaning, water splash, movement or load. In bathrooms, avoid showering or washing down the area too soon, because early disturbance can compromise adhesion at the edges. Good ventilation supports cure development, especially in enclosed rooms. If you need to paint, allow full cure first and test compatibility with the chosen water based paint system.

Q) Can Soudal Fix ALL Crystal Foil Packs be painted over once cured?

A) Yes, it can be painted with many water based paint systems once cured, which is useful if the clear bead needs to disappear into a decorated finish. The key is to let it cure sufficiently first, because paint can restrict curing if applied too early and may crack if the sealant is still moving internally. Always do a small compatibility test with the exact paint you plan to use, because paint flexibility varies widely and the paint film must be elastic enough to move with a permanently elastic joint. Be aware that painting a clear bead can change its visual effect, especially on glossy surfaces, so test the finished look before committing across a high visibility area.

Q) How do I estimate coverage from a 600ml foil pack?

A) Coverage depends on joint width and depth, so calculate based on volume rather than relying on a single metres per pack figure. Narrow sanitary beads can run a long distance, while wider sealing joints and adhesive beads will use material much faster. For accurate planning, use the Platinum Chemicals Sealant Estimate Calculator and input the joint dimensions and total run length, then add a sensible margin for corners, tooling, nozzle trimming and stop start losses. One advantage of the 600ml format is fewer reloads, which helps you keep bead size consistent and reduces defects in visible joints. Consistent nozzle cuts also help coverage accuracy, so avoid changing bead size mid job unless the joint detail demands it.

Q) What is the best way to clean up during application and remove cured residue?

A) Clean immediately while the product is fresh, especially because clear smears can be hard to spot until they catch the light. Use Soudal Swipex Wipes to remove uncured sealant from tools and non porous surfaces, keeping wipes clean so you do not spread a thin film across glossy finishes. If you are masking, remove tape straight after tooling to keep edges sharp and reduce clean up. Once cured, the sealant generally needs mechanical removal. Soudal Sealant Remover Spray can help soften and lift residue during removal, but always test first on plastics, coated metals and painted surfaces. Avoid aggressive scraping on delicate finishes and re clean the joint faces properly before re sealing.

Q) What are the most common mistakes that ruin the clear, invisible finish?

A) The most common issues are poor preparation, inconsistent bead sizing and slow tooling. Any dust, grease, soap film or old sealant residue at the edges can cause edge lift, which is very noticeable on a clear joint. Air pockets and stop start beads also show up more in transparent sealant, especially in bright light. Tooling too late is another problem because skinning is fast, so the surface can drag and leave marks if you wait. Over wiping can smear a thin film across surrounding surfaces that only becomes obvious later. Masking helps control lines, but only if you remove tape promptly. Finally, avoid letting finishing solutions contaminate the adhesion faces, as this can weaken the bond and spoil the joint over time.

Q) What limitations should I be aware of before choosing this product?

A) Soudal Fix ALL Crystal Foil Packs is not suitable for continuous water immersion, and it is not intended for large expansion joints. It is also not a glazing sealant, so for glazing systems and façade joints use Silirub 2 or Silirub LMN. Do not use it on PE, PP, PTFE (Teflon®), bituminous substrates, or copper, bronze and brass. It is not suitable for aquarium bonding, use Silirub AQ. Avoid stress loaded bonding on PMMA (Plexi® glass) and polycarbonate, and for polycarbonate sealing use Silirub PC. Avoid contact with EPDM and other plasticiser releasing materials, and where EPDM is present use Silirub EPDM. Mould resistance supports cleaner joints, but it does not replace normal cleaning and good ventilation in wet rooms.

Q) Does it have low odour, low emission, or food area compliance credentials?

A) Yes. Soudal Fix ALL Crystal Foil Packs is described as virtually odourless and is positioned for use in sensitive internal environments where strong smells are undesirable. It also carries food related compliance credentials, including ISEGA declaration of compliance and reference to FDA CFR 21 177.2600(e) for repeated contact with aqueous foods within the regulation scope. For low emission specification, it aligns with LEED low emitting materials expectations for adhesives and sealants, referencing SCAQMD Rule 1168 and USGBC LEED 2009 Credit 4.1 requirements for VOC content, subject to project documentation. In practical terms, that makes it a strong choice for kitchens, catering adjacent zones and occupied buildings where indoor air quality considerations are important.

Q) How should I store foil packs and what practical tips help avoid waste?

A) Store foil packs sealed, in their original packaging, and protect them from extreme temperatures and moisture so the product does not begin curing prematurely. Once opened and fitted to the Soudal 600ml Manual Foil Cartridge Gun, keep the nozzle clean and avoid leaving the pack exposed for long periods, because skinning can occur at the tip and affect flow. If you need to pause, cap the nozzle and keep the gun in a clean, dry place. One benefit of foil packs is reduced residual waste, but you still minimise losses by cutting the nozzle only as large as needed and planning runs so you can use a steady bead without frequent stops. For visible joints, work in consistent lengths you can tool immediately, because fast skinning rewards good organisation.
