Soudal D2 Superfast PVA Wood Adhesive

Health & Safety Recommendations

When using Soudal D2 Superfast PVA Wood Adhesive, normal good workshop hygiene should always be observed. Work in a well ventilated area and avoid unnecessary skin and eye contact with the liquid adhesive. Protective gloves are advisable for regular or prolonged use, and safety glasses should be worn if there is any risk of splashing during spreading or clamping.

Do not eat, drink or smoke while handling the product and always wash hands after use. In case of accidental contact with eyes, rinse immediately with plenty of clean water and seek medical advice if irritation persists. Keep the container tightly closed when not in use and store out of reach of children.

For full and up to date safety information, the product label and material safety data sheet should always be consulted before professional or large scale use.

Substrate Suitability

Soudal D2 Superfast PVA Wood Adhesive is designed for bonding porous substrates in interior woodworking and joinery. It is highly suitable for most common wood species, engineered timber products, chipboard, fibreboard, plywood, carton and paper based materials.

The adhesive relies on absorption into the surface, so best results are achieved on porous or semi-porous substrates rather than non-absorbent plastics or metals. Certain timbers, such as some tropical hardwoods and particular grades of oak, contain extractives that can migrate into the glue line and may cause localised staining; for critical visible work these combinations should be trialled first.

Because timber density, surface preparation and moisture content vary, a preliminary adhesion test on every unfamiliar substrate is strongly recommended before committing to full scale bonding.

Surface Preparation

Surfaces must be flat, well fitting and accurately machined so that the joint closes properly under clamping pressure. Both bonding faces should be clean, dry and free from dust, grease, oil, release agents, old adhesive residues and loose fibres.

Any contamination will reduce the wetting and penetration of the PVA wood glue and weaken the bond. The timber moisture content should be within the normal working range for interior joinery, not excessively wet or freshly treated with water based products. Smooth, non-porous or very dense surfaces may benefit from light sanding or fine grinding to open the surface and improve mechanical key.

After sanding, dust should be removed thoroughly with vacuum or a clean brush. Do not attempt to bond frozen or waterlogged materials and avoid gluing below the minimum film forming temperature of around 6°C, as this can prevent the adhesive from forming a continuous, strong film.

Application Method

The adhesive is supplied ready to use and must not be diluted. Stir gently if required, then apply a uniform coat to one of the bonding faces using a fine toothed glue comb, spreader, brush or suitable applicator.

For full surface bonding such as laminating panels or veneer, spread the D2 wood adhesive so that the entire area is covered with a thin, even film, avoiding puddles or dry patches. For assembly gluing in joints, ensure that all contact faces receive sufficient glue to wet the surfaces thoroughly without excessive squeeze out.

Once the adhesive has been applied, bring the mating parts together within the open time, which is typically about five minutes at 23°C and 55% relative humidity. Carefully align the components and apply clamping pressure across the joint.

Recommended pressing pressure is in the range of 1 kg per square centimetre to 2 kg per square centimetre, using suitable clamps, presses or other jigs to maintain intimate contact.

The quality of the bond is governed more by the adequacy of pressure and fit than by very long pressing times, so joints should be brought up to pressure firmly and evenly as soon as possible after assembly.

Coverage

Typical consumption of Soudal D2 Superfast PVA Wood Adhesive will depend on the porosity and smoothness of the substrates as well as the application technique. As a general guide, for full surface bonding such as laminating boards or bonding veneers, approximately 80g to 120g per square metre of glue spread is usually sufficient when the adhesive is applied as a continuous, even film.

For assembly work such as edge bonding, tongue and groove joints or mortise and tenon connections, usage will typically be higher, often in the region of 150 to 180 g per square metre of bonded area, because more glue is required to wet end grain and fill minor irregularities.

Excessively heavy application does not improve bond strength and may increase squeeze out and pressing time, so aiming for the recommended spread rates provides the best balance between performance and economy.

Drying Time

Curing of this PVA wood adhesive occurs by physical drying as water evaporates into the surrounding timber and air. At a reference condition of 23°C and 55% relative humidity, the open time is around five minutes, which is the period within which the parts should be brought together and clamped.

Once the joint is under pressure, a minimum pressing time of about thirty minutes is recommended to achieve handling strength. Lower temperatures or higher humidity will extend the pressing time, while warmer, drier conditions will shorten it. Full cure and ultimate bond strength are reached after several hours to a day depending on timber thickness, absorbency and ambient conditions.

Assemblies should not be heavily loaded, machined aggressively or stressed until the adhesive has dried thoroughly through the joint. Working below 5°C is not recommended, and the adhesive should not be used where the temperature remains below its minimum film forming temperature of about 6°C during curing.

Cleaning

Wet Soudal D2 Superfast PVA Wood Adhesive can be removed from tools, equipment and substrates with clean water before it has dried. Wipe up any squeeze out immediately with a damp cloth or sponge, rinsing frequently to avoid smearing glue over adjacent surfaces.

For best results when bonding visible joints, it is good practice to remove surplus adhesive at the gel stage, when it has thickened slightly but has not fully hardened, as this reduces the risk of raised grain or staining. Once cured, the adhesive becomes water resistant to EN204 D2 and can no longer be removed with water; any hardened residue must be removed mechanically by scraping, sanding or planing.

Tools and spreaders should be cleaned promptly after use to prevent build up of dried PVA on working edges, which can interfere with accurate application on future jobs.

Limitations

Soudal D2 Superfast PVA Wood Adhesive is designed for interior use and is classified to EN204 as D2, which means it is suitable for joints exposed to normal interior humidity with only occasional brief moisture exposure. It is not intended for exterior joinery, immersed service or applications subject to prolonged wetting, where a higher class D3 or D4 adhesive would be more appropriate.

The product is optimised for porous materials and is not suitable for bonding non-porous plastics, metals or substrates such as polyethylene, polypropylene or PTFE. When working with certain oak or tropical hardwoods, natural extractives may cause discolouration at the bond line, so critical work should always be tested first.

The adhesive must not be diluted with water or mixed with other products, as this can alter its viscosity, solids content and performance. It should not be used at temperatures below 5°C or on frozen, saturated or contaminated surfaces, as this will compromise curing and bond strength.

Other Information

Soudal D2 Superfast PVA Wood Adhesive is based on a high viscosity PVAc dispersion with a density of approximately 1.10 g per millilitre and a solids content of about 50%, giving a good balance of spreadability and rapid strength build up. The viscosity, typically in the range of 30,000 to 40,000 mPa.s, allows the glue to stay in place on vertical or end grain joints while still being easy to brush or comb out.

The pH is around 4.0 to 5.5, which is typical for PVA wood glues and compatible with most interior timber species when normal workshop practice is followed. As with all wood adhesives, best results are achieved when the timber is conditioned to the environment where it will be installed and when joints are well designed, accurately machined and clamped correctly.

Storing the adhesive in a frost free environment and keeping the container closed when not in use will help preserve its shelf life and performance. For professional carpentry, cabinet making and interior woodworking, this D2 rated PVA glue provides a fast, reliable and easy to use bonding solution when used in line with these guidelines.

Q) What is Soudal D2 Superfast PVA Wood Adhesive and what is it designed for?

A) Soudal D2 Superfast PVA Wood Adhesive is a ready to use, professional PVA wood glue for interior joinery, furniture and general carpentry. It is formulated to give a fast, high strength bond on most wood and wood based substrates, drying to a discreet semi-transparent glue line. The product suits softwood, many hardwoods, chipboard, MDF, plywood, blockboard, veneer and paper laminates. Because it is a single component liquid, it needs no mixing or dilution and can be used straight from the bottle. This makes it ideal for repeatable workshop use and accurate, clean assembly on site. 

Q) Which typical jobs is Soudal D2 Superfast PVA Wood Adhesive most suitable for?

A) Soudal D2 Superfast PVA Wood Adhesive is intended for interior furniture making, cabinet work, carcass construction and general joinery where fast turnaround and strong, neat joints are required. It performs well on mortise and tenon joints, dowels, tongue and groove connections, edge laminations and panel assembly. The semi-transparent glue line makes it particularly useful for visible joints in furniture, shelving, doors, frames and veneered panels. It is also suitable for kitchen and bedroom carcasses located in normal indoor conditions. For small carpentry repairs, craft projects and modelmaking it offers easy handling, rapid curing and a professional quality finish.

Q) What types of materials can Soudal D2 Superfast PVA Wood Adhesive bond successfully?

A) Soudal D2 Superfast PVA Wood Adhesive is designed for porous, wood based materials. It bonds softwood, many hardwoods, chipboard, MDF, plywood, blockboard, fibreboard, carton and paper based laminates. Because it relies on absorption into the surface, it is not suitable for non-porous plastics or metals. Some dense or oily tropical hardwoods and certain oaks can contain extractives that affect adhesion or cause local staining at the glue line. In those cases, a small test is recommended before visible work. Provided the substrates are clean, dry and reasonably porous, the adhesive will form a strong, long lasting interior joint.

Q) What does the D2 rating of Soudal D2 Superfast PVA Wood Adhesive actually mean?

A) The D2 classification for Soudal D2 Superfast PVA Wood Adhesive comes from EN204, which defines water resistance classes for wood glues. A D2 adhesive is suitable for interior applications where joints experience normal indoor humidity and only occasional brief moisture, for example kitchen furniture away from direct water, interior doors, skirtings and general fit-out. It is not intended for prolonged wetting, exterior exposure or immersion. For permanently damp locations, exterior joinery or areas subject to frequent water contact, a higher class such as D3 or D4 is more appropriate. Used correctly indoors, D2 offers reliable service.

Q) How quickly does Soudal D2 Superfast PVA Wood Adhesive set and when can clamps be released?

A) Soudal D2 Superfast PVA Wood Adhesive has an open time of roughly five minutes at 23°C and 55% relative humidity, which is the period in which the parts must be assembled and clamped. Once under pressure, joints typically reach basic handling strength after about thirty minutes in average workshop conditions. Cooler temperatures, very dense timber or high humidity will extend this time, while warmer, drier conditions shorten it. Full strength develops over several hours as water diffuses into the timber. Assemblies should not be heavily loaded or machined aggressively until the adhesive has fully dried through the joint.

Q) What is the correct way to apply Soudal D2 Superfast PVA Wood Adhesive to a joint?

A) Soudal D2 Superfast PVA Wood Adhesive is used undiluted. Apply a thin, even film to one bonding face with a brush, roller, glue spreader or nozzle. For veneers or full panel laminations, ensure continuous coverage with no bare patches or puddles. For assembly joints, coat all contact surfaces so the glue fully wets the wood but only a modest bead squeezes out. Bring the parts together within the open time, align accurately, then clamp evenly. Pressing pressures of around 1–2 kg/cm² are usually sufficient when joints are accurately machined and fit well without excessive gaps.

Q) How should timber and surfaces be prepared before using Soudal D2 Superfast PVA Wood Adhesive?

A) To get the best from Soudal D2 Superfast PVA Wood Adhesive, joints must be well fitting and clean. Both faces should be dry, free from dust, oil, grease, release agents and loose fibres, as contamination will weaken the bond. Timber should be at a normal interior moisture content, not freshly saturated or waterlogged. Very smooth, sealed or dense surfaces may benefit from light sanding to open the grain, followed by thorough dust removal. Do not attempt to glue frozen materials or work below about 6°C, as low temperatures prevent the PVA film forming correctly and reduce strength.

Q) What sort of clamping and pressure does Soudal D2 Superfast PVA Wood Adhesive require?

A) Soudal D2 Superfast PVA Wood Adhesive is designed to achieve high strength bonds at moderate clamp pressures. In most cases, between 1 kg/cm² and 2 kg/cm² is adequate, provided joints are accurately machined and close fitting. The purpose of pressure is to bring the glued surfaces into intimate contact and squeeze out air, not to crush the timber. Use enough clamps to distribute force evenly across the joint, avoiding point loads that can distort components. Clamps should be tightened soon after assembly, within the open time, then left for at least the minimum pressing period before removal.

Q) How much coverage can I expect from Soudal D2 Superfast PVA Wood Adhesive in typical use?

A) Coverage with Soudal D2 Superfast PVA Wood Adhesive depends on surface texture, porosity and spreading method, but some general figures are useful. For full surface bonding such as veneers or laminating boards, around 80–120 g/m² is usually sufficient when applied as a continuous, thin film. Assembly joints like edge bonding, tongue and groove or mortise and tenon often consume 150–180 g/m² of bonded area because end grain and irregularities absorb more glue. Over-application does not notably increase strength and simply creates more squeeze out, so aiming for these ranges balances performance with economical use.

Q) In what situations should I not use Soudal D2 Superfast PVA Wood Adhesive?

A) Soudal D2 Superfast PVA Wood Adhesive should not be used for exterior joinery, permanently damp locations, immersed conditions or applications subject to frequent water contact, because its D2 rating is only intended for interior service with occasional moisture. It is unsuitable for bonding non-porous plastics, metals or materials such as polyethylene, polypropylene and PTFE, where lack of absorption prevents proper curing. The glue should not be diluted, mixed with other products or used below about 5–6°C. Very oily or exotic hardwoods may require alternative adhesives or thorough testing, especially for highly visible joints where staining is unacceptable.

Q) How can squeeze out and spills of Soudal D2 Superfast PVA Wood Adhesive be cleaned up?

A) While still wet, Soudal D2 Superfast PVA Wood Adhesive can be cleaned away with clean water. Wipe squeeze out promptly using a damp cloth or sponge, rinsing frequently to avoid smearing glue across neighbouring timber. Some woodworkers prefer to let the adhesive reach a gel stage, when it is rubbery rather than liquid, then pare it away carefully with a chisel to minimise grain raising. Once fully cured, the adhesive becomes water resistant and must be removed mechanically by scraping, sanding or planing. Tools and applicators should be washed immediately after use to prevent dried build-up.

Q) How should Soudal D2 Superfast PVA Wood Adhesive be stored and are there any key safety points?

A) Soudal D2 Superfast PVA Wood Adhesive should be stored in its original, tightly closed container in a frost free place, away from direct heat or sunlight. Freezing can irreversibly damage the dispersion. Normal workshop precautions apply: avoid prolonged skin contact, prevent splashes to the eyes and keep the product out of reach of children. Use in a reasonably ventilated area and wash hands after use. If adhesive enters the eyes, rinse immediately with plenty of clean water and seek medical advice if irritation persists. Always check the product label and safety data sheet for full, up to date guidance.
