D4 wood adhesive is used across joinery, carpentry and furniture making wherever a waterproof, high-strength bond is required. External doors and frames, garden furniture, window boards, conservatory joinery and hardwood flooring installations are all common applications. It handles internal workshop use just as well, making it a single-product solution for joiners who work across both environments rather than keeping two different glues on the shelf.

Not suitable for: Not suitable for bonding non-porous materials such as metal, glass, or plastics. Not recommended as a gap-filling adhesive where joint fit is poor, as it requires close-fitting surfaces for a reliable bond.
Ensure both surfaces are clean, dry and well-fitting. Apply a thin, even coat of adhesive to both mating surfaces, bring them together, and clamp firmly. Wipe away any squeeze-out with a damp cloth before it cures. Allow at least ten minutes before removing clamps under light load, though full cure strength develops over 24 hours depending on temperature and timber species.
Ensure both timber surfaces are clean, dry, and free from dust, grease or previous adhesive residue
Apply a thin, even coat of D4 wood adhesive to both mating surfaces
Bring the surfaces together immediately and align carefully
Apply firm, even clamping pressure across the joint
Wipe away any excess adhesive that squeezes out using a damp cloth before it sets
Leave clamped for a minimum of ten minutes, longer in cold conditions
Allow 24 hours before subjecting the joint to full load or stress
What is the difference between D3 and D4 wood adhesive?
D3 is water-resistant, meaning it will tolerate occasional moisture exposure but is not suitable for prolonged or repeated wetting. D4 is fully waterproof and can withstand long-term exposure to water, making it the right choice for external joinery, garden furniture, and anything that will regularly get wet or sit in a damp environment.
Does Everbuild D4 Wood Adhesive work on hardwoods like oak?
Yes. It bonds well to both hardwoods and softwoods. Dense, oily hardwoods such as teak or iroko can be more challenging for any adhesive, so it's worth scuffing the surface and wiping with a clean cloth to remove surface oils before applying. For oak and most standard hardwoods, no special preparation is needed beyond the usual clean, dry surface.
Can I use D4 wood adhesive in cold conditions?
Performance drops below around 10 degrees Celsius. The adhesive will still bond but set time increases and the joint should be kept clamped for longer before being disturbed. Avoid applying to frozen or frost-covered timber, and don't store the adhesive where it could freeze, as this will damage the formulation.
Everbuild D4 Wood Adhesive is a hybrid resin-based, solvent-free adhesive formulated to meet the requirements of EN204 D4 and WATT91, the recognised standards for waterproof wood bonding. The cured bond is resistant to water immersion, temperature variation, and impact loading, and typically exceeds the tensile strength of the timber substrate itself. The formulation is water-based, allowing clean-up before cure with water alone.
