Soudal Assembly Lubricant

Health & Safety Recommendations

Read the label and safety data sheet before use. Apply Soudal Assembly Lubricant only in well-ventilated areas and keep away from ignition sources, hot surfaces and open flames. Avoid inhaling spray or vapour and avoid contact with skin and eyes.

Wear suitable gloves and eye protection, especially when working overhead or inside enclosures. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice if irritation persists. Prevent overspray on floors, as the silicone film can create a slip hazard.

Do not smoke during application and respect all precautions for use printed on the packaging.

Substrate Suitability

This silicone-oil assembly spray is suitable for plastics, metals and rubbers commonly encountered in push-fit pipework, gaskets, seals, trims, locks, hinges and tools. It is designed as a clean slide coating and light lubricant for assembly and maintenance where a non-staining, water-repellent film is preferred.

On sensitive plastics, fresh paint, decorative coatings or where bonding/painting will follow, carry out a small compatibility test first; silicone contamination can interfere with paint and adhesive adhesion.

Surface Preparation

Fittings, pipes and mating parts should be clean, degreased and dry to allow the lubricant to wet out evenly and to ensure trouble-free insertion. Remove dust and loose debris with a lint-free cloth.

Where heavy grime or old grease is present, degrease and wipe dry so the silicone film contacts the substrate directly. For locks, hinges and small mechanisms, brush away loose dirt before treatment to aid penetration.

Application Method

Shake the aerosol thoroughly before use. Hold the nozzle 10–20cm from the subject and apply a thin, even layer to the parts to be assembled. For push-fit plastic pipes and rubber strips/joints, coat both mating surfaces lightly, then assemble promptly; the transparent film provides a low-friction slide coating that helps parts seat fully without tearing seals.

When used as a lubricant for hinges, latches and fittings, hold the nozzle close to the moving interface, carefully press the valve to deliver a controlled dose, operate the mechanism several times to distribute the silicone oil, and allow the product to work for a short period before wiping away any excess.

Avoid flooding porous materials and avoid application to surfaces that will be painted or bonded. Apply only within the recommended application temperature range and reapply as needed to maintain a visible, even film.

Drying Time

Soudal Assembly Lubricant forms a functional film within minutes at typical room conditions. Drying/evaporation depends on application thickness, temperature, airflow and humidity.

Allow complete evaporation before restoring power to any isolated equipment and before handling components that must remain dry and non-slip.

Cleaning

Wipe away surplus lubricant with a clean lint-free cloth to minimise dust pick-up. If overspray reaches areas intended for subsequent painting or bonding, remove promptly with an appropriate silicone remover or solvent compatible with the substrate, then wash with a mild detergent and allow to dry.

Keep the actuator and any extension tube clean so the spray pattern remains accurate for the next task. Wash hands after use and dispose of used wipes in accordance with local regulations.

Other Information

Basis is a mixture based on silicone oil; consistency is fluid. Recommended application temperature is 5°C→35°C. Do not use this product in connection with painting; treated surfaces cannot be painted unless thoroughly de-siliconised. Performance depends on substrate condition and application technique; the user should verify suitability via a small trial and adopt safe systems of work.

For best results on assembly tasks, use as a clean slide coating rather than a heavy-duty bearing lubricant, and incorporate into a regular maintenance routine for seals, gaskets and mechanisms to maintain smooth operation and protect rubber parts from premature ageing.

Q) What is Soudal Assembly Lubricant and what does it do?

A) Soudal Assembly Lubricant is a premium silicone oil based spray that creates a clean, transparent slide coating to speed up assembly and restore smooth movement. It reduces friction and wear on contact surfaces, helps parts seat fully without binding, and lifts light dirt and handling grime as you apply it. Once in place, the film is water repellent, so treated components shed moisture and resist fresh contamination, extending the interval between maintenance. Because the coating is dry-feeling and non-staining, it keeps work areas tidy and avoids the dust attraction that ordinary oils can cause. It is safe on plastics, rubbers and common metals, making it ideal for push-fit plastic pipework, rubber strips, gaskets and seals, as well as for quietening and freeing sluggish locks, hinges, fittings and tools. The 360° any-angle aerosol enables accurate, low-mess application even in tight or overhead locations.

Q) How does Soudal Assembly Lubricant work to improve sliding and assembly?

A) The spray lays down an ultra-smooth silicone film that spreads rapidly across the surface, filling fine irregularities and forming a very low-friction interface. This reduces stiction at start-up, lowers running resistance as parts move, and limits surface scuffing that can lead to premature wear. During application, the lubricant also lifts and disperses light dirt and traces of old lubricant, so components look and feel clean as they go together. Once the parts are assembled, the hydrophobic film sheds water and helps block grime build-up, which maintains an easy-sliding action for longer. On rubber, the coating supports elasticity and surface feel, reducing squeaks and sticking and helping to prevent early ageing. On plastics and coated metals, it can serve as a neat anti-stick layer for light assembly duties where a clean, non-staining lubricant is essential. The result is faster assembly with less force and a more professional finish.

Q) Where should Soudal Assembly Lubricant be used and which tasks benefit most?

A) Use Soudal Assembly Lubricant wherever clean, controlled slip is needed to seat parts fully and prevent damage to delicate materials. Typical wins include inserting plastic pipes into push-fit fittings, positioning rubber strips, weatherstrips and glazing gaskets, and seating O-rings without twisting or tearing. It is equally useful for restoring smooth movement on locks, latches and hinges in doors, cabinets and enclosures, and for easing runners, slides and small guides in window and door systems. In workshops and on site it acts as a tidy anti-stick aid on chutes and assembly jigs, and in automotive, marine and plant maintenance it helps seals, trims and light linkages resist water and dirt. Facilities teams use it to keep gasket profiles and moving interfaces operating quietly across a site. Because the aerosol works at any angle, it gets product exactly where it’s needed inside housings, behind panels and overhead.

Q) Is Soudal Assembly Lubricant safe on plastics, rubbers and metals?

A) Yes. Soudal Assembly Lubricant is formulated for compatibility with common engineering materials and is safe for use on most plastics, rubbers and metals typically encountered in assembly and maintenance. That makes it suitable for mixed assemblies that include seals, trims, gaskets, coated metals and plastic housings. As with any lubricant, sensitivity can vary between specific polymers, fresh paint and decorative coatings, so it is prudent to perform a small compatibility test on an inconspicuous area where appearance is critical or where later finishing work is planned. Avoid deliberate application to surfaces that must remain non-slip, and be aware that silicone transfer can interfere with paints and adhesives. Used as directed—light, targeted films on clean substrates—the product delivers broad, practical compatibility without staining or degrading common materials.

Q) How should I prepare parts before applying Soudal Assembly Lubricant?

A) Good preparation ensures the lubricant can wet out evenly and do its job at the true point of contact. Begin by cleaning fittings, pipes and mating parts so they are free from dust, loose debris and heavy grease; a wipe with a lint-free cloth is often sufficient, while heavily soiled items should be degreased and dried. On locks, hinges and small mechanisms, brush away grit so the spray can reach pivots and sliding faces. If you plan to assemble rubber strips or gasket profiles, check that the surfaces are dry and free from mould release residues that might block wetting. Mask off any adjacent areas that must later be painted or bonded to avoid silicone transfer. With the work prepared in this way, a light application of Soudal Assembly Lubricant forms a uniform, low-friction film that speeds assembly and helps prevent damage to delicate elastomers.

Q) What is the correct application method for push-fit plastic pipes and rubber strips with Soudal Assembly Lubricant?

A) Shake the can thoroughly, then hold the nozzle 10–20 cm from the parts and apply a thin, even coat to both mating surfaces. For push-fit plastic pipes, coat the spigot and the fitting mouth lightly—there is no need to flood the joint—then assemble promptly, maintaining alignment so seals are not nicked or twisted. For rubber strips and gaskets, mist the contact faces, position the profile and work it smoothly into place; a gentle wipe can help distribute the film and remove surplus. The transparent silicone layer provides the slip needed for a full seat without tearing or stress, and because it is dry-feeling and non-staining it keeps the workspace tidy. Operate the joint or closure a few times to confirm free movement. If resistance is still felt, apply a very light additional pass—thin films work better than heavy coats and minimise dust pick-up.

Q) How do I use Soudal Assembly Lubricant on locks, hinges, fittings and tools?

A) Target only the moving interfaces. Fit the extension tube for accuracy, apply a brief dose directly to the pivot, latch tongue, cylinder or slide, then operate the mechanism several times to draw the lubricant into contact faces. A second light application can be used if movement remains sluggish. Wipe away any visible surplus to avoid attracting dust and to prevent slip hazards on nearby surfaces. On tools and small workshop hardware, a light pass on guides and slides reduces drag and improves feel without leaving greasy residues. Because the film is water repellent, it also provides incidental protection against moisture during service. Avoid flooding porous materials and keep overspray off areas that will later be painted or bonded. The aim is a clean, controlled film that restores smooth, quiet action without mess.

Q) Does Soudal Assembly Lubricant also clean and protect, or is it just a lubricant?

A) It does more than lubricate. During application Soudal Assembly Lubricant lifts and disperses light dirt, handling grime and traces of old lubricant, so parts present cleanly for assembly. After the volatile carrier has evaporated, the silicone film that remains is hydrophobic and dirt-shedding, which helps treated components resist fresh contamination. On metal surfaces this also translates into incidental protection against corrosion during service. On rubber, the coating supports suppleness and appearance, countering surface drying and reducing squeaks and sticking. The combination of light cleaning, low-friction sliding and a water-repellent protective layer makes the product a practical “apply and improve” step in assembly, installation and routine maintenance where cleanliness matters.

Q) Can Soudal Assembly Lubricant be used overhead and in confined or awkward locations?

A) Yes. The aerosol is fitted with a 360° any-angle valve that allows consistent spraying in every orientation, so you can apply Soudal Assembly Lubricant overhead, inside housings, behind panels and in recesses without repositioning the can. This makes accurate treatment of runners, stays, gasket grooves and concealed hinges straightforward. Use the extension tube to direct the jet precisely and keep films thin to minimise overspray. In confined spaces, ensure ventilation so the carrier can evaporate promptly after application. The ability to spray at any angle is a major practical advantage on site and in maintenance, letting you deliver the lubricant exactly where it is needed with minimal mess.

Q) Can surfaces treated with Soudal Assembly Lubricant be painted, bonded or sealed afterwards?

A) No, not without thorough de-siliconising first. Silicone contamination can cause paint defects such as fisheyes, interfere with adhesive bonding and compromise sealant adhesion. If a treated area later requires coating or bonding, remove the silicone with an appropriate silicone remover or solvent compatible with the substrate, then wash with a mild detergent and allow to dry before finishing. The simplest approach is to plan the sequence: complete painting or bonding first, and apply Soudal Assembly Lubricant only to moving parts and non-critical surfaces afterwards. Masking adjacent finishes during application also helps avoid transfer. Treating surfaces that must remain paintable or bondable is not recommended.

Q) What are the limitations of Soudal Assembly Lubricant and when should I choose another product?

A) Soudal Assembly Lubricant is a clean, light-duty slide coating and assembly aid; it is not a heavy-load bearing grease, long-term corrosion inhibitor or structural adhesive. Do not rely on it for highly loaded bearings, gearboxes or applications requiring persistent, high-pressure lubrication—use the specified grease or oil for those. Avoid treating surfaces that must be painted or bonded later, and do not flood porous materials that could retain excess fluid. The product is intended for assembly and light mechanism lubrication, not for restoring damaged parts; torn seals, worn hinges and distorted fittings should be repaired or replaced. If you have very sensitive plastics, fresh decorative coatings or finishes of unknown composition, test a small area first to confirm compatibility before full use.

Q) What safety and handling advice applies when using Soudal Assembly Lubricant?

A) Read the label and safety data sheet before use. Apply only in well-ventilated areas and keep away from ignition sources, hot surfaces and open flames. Avoid inhaling spray or vapour and avoid contact with eyes and skin; wear suitable gloves and eye protection, especially when working overhead or inside enclosures. Prevent overspray on floors, as the silicone film can create a slip hazard; wipe spills promptly. If the product contacts eyes, rinse immediately with plenty of clean water and seek medical advice if irritation persists. Do not smoke during application. Store and transport the aerosol upright where possible and do not expose the can to temperatures above 50°C. Dispose of used wipes in accordance with local regulations and wash hands after work.

Q) What practical hints and tips will help me get consistent results with Soudal Assembly Lubricant?

A) Less is more: thin, even films lubricate better and stay cleaner than heavy coats. Always clean or wipe parts first so the silicone can wet the true contact surfaces. For push-fit pipes, coat both the spigot and fitting lightly and assemble promptly to avoid dust settlement. For seals and gasket profiles, mist the contact faces, position carefully and work along the length to avoid trapping twists. Operate mechanisms several times after application to distribute the film, then wipe off visible excess. Keep the actuator and extension tube clean so the spray pattern remains accurate, and store the can at room temperature for consistent delivery. Plan your sequence—complete any painting or bonding before using the product—and mask nearby finishes if overspray would be a problem.

Q) What finish does Soudal Assembly Lubricant leave and will it stain or mark surfaces?

A) The product leaves a transparent, dry-feeling silicone film with a neat, subtle gloss on plastics and rubber. Because it is non-staining and low residue, it is well suited to visible assemblies where a clean appearance matters, such as trims, seals and housings. It will not yellow or leave oily tide marks in normal use, and it helps restore a fresh look to tired rubber by enhancing surface sheen. As with any silicone product, avoid contact with areas that will later be painted or bonded, and remove any unintended overspray promptly with a suitable silicone remover followed by a mild detergent wash. Applied correctly, Soudal Assembly Lubricant delivers a tidy, professional finish without mess.

Q) Can Soudal Assembly Lubricant act as a light anti-stick or release aid in assembly work?

A) Yes. On plastics and coated metals Soudal Assembly Lubricant provides a neat, low-friction surface that helps parts separate cleanly during light assembly and processing tasks. This can speed bench work on jigs, chutes and guides where a clean anti-stick is more appropriate than a heavy oil. Apply a very light film to the working surface, allow the carrier to evaporate, and then proceed with handling. Because the coating is transparent and dry-feeling, it avoids the dust pick-up and transfer that can occur with conventional oils. As always, keep it away from any surfaces that will later be painted or bonded, and refresh the film periodically if the effect begins to fade during production.

Q) How should Soudal Assembly Lubricant be stored, how do I clean overspray, and how do I remove it if finishing work is planned?

A) Store the aerosol upright in a cool, dry place away from direct sunlight and heat sources, and never allow it to exceed 50°C. After use, wipe the nozzle and extension tube to keep the spray pattern precise, and consider a quick test spray into a cloth before the next job to confirm the valve is clear. If overspray reaches unintended areas, remove it promptly with a silicone remover or a solvent compatible with the substrate, then wash with a mild detergent and allow to dry. Where painting or bonding is planned, thoroughly de-siliconise the surface using the same approach and confirm by a small test before full finishing. Good housekeeping—clean parts, thin films, prompt wipe-downs—keeps the product delivering clean, repeatable results with minimal rework.
