PVA (Polyvinyl Acetate) is a broad category of water-based adhesive used across many building applications, including bonding, priming, and sealing porous surfaces like plaster, brick, and timber. Wood glue is a type of PVA that is specifically formulated for timber joinery. It penetrates the grain of the wood and typically creates a bond stronger than the wood itself once cured. Standard PVA is fine for general building use, but for structural timber joints, a dedicated wood glue gives better results. Always check whether the product is rated for interior or exterior use if moisture is a concern.
Adhesives for Every Trade and DIY Job
Getting the right adhesive for a job saves time and avoids rework. MacBlair stocks a broad selection covering trade and DIY applications, from quick general repairs to structural fixings in walls and floors. The range includes products suited to timber, flooring, felt roofing, and anchoring bolts into masonry.
The adhesive sub-categories cover the most common building and joinery needs:
- PVA — a multi-purpose bonding agent, primer, and sealer used across most interior building surfaces
- Wood Glues — formulated to penetrate timber grain and create bonds that hold through natural wood movement
- Multi Purpose Glues — for everyday repairs and bonding across a variety of materials
- Contact Adhesives — coat both surfaces, allow to dry to touch, then press together for an instant, strong bond
- Anchoring Resins — two-part resin systems for fixing bolts, rods, and fixings into concrete or masonry
- Felt Adhesive — specifically for bonding roofing felt to timber decking
- Floor Adhesive — for bonding flooring materials directly to subfloors
Picking the right product comes down to the substrate and conditions. PVA needs at least one porous surface to grip properly. Contact adhesives suit laminates and rubber where clamping is not practical. Anchoring resins are the go-to where a mechanical fixing needs to carry load in masonry. For floor adhesive and felt adhesive, surface prep matters: clean, dry, and dust-free surfaces give the strongest results. Check the individual product data sheets for curing times, particularly in cold or damp conditions.
The grab adhesives range is also worth considering for vertical applications where the material needs to hold in place before the bond fully cures. If the project also involves mechanical fixings, the full fixings range at MacBlair covers wall plugs, anchors, and frame fixings to complement adhesive bonds where extra hold is needed.
Adhesive FAQ's
Contact adhesive is the right choice when bonding non-porous materials like laminate, rubber, or metal, where PVA would not grip reliably. The method is different too: apply the adhesive to both surfaces, allow it to become touch-dry, then press firmly together. The bond forms on contact and there is no repositioning once the surfaces meet, so careful alignment is essential. Contact adhesive is also useful where clamping is not practical, such as fixing large sheet materials to vertical surfaces.
Anchoring resins are two-part chemical fixings used to secure bolts, threaded bars, and rods into concrete, brick, or blockwork where a mechanical wall plug would not provide enough holding strength. They are commonly used for fixing structural brackets, handrails, and heavy-duty fittings. The resin is injected into a drilled hole, the fixing is inserted, and the resin cures around it to create a very strong bond with the masonry. Always follow the manufacturer's curing time before applying any load to the fixing.
No. Floor adhesives are formulated for specific flooring types, so it is important to check the product is compatible with the material being laid. Some are designed for wood and engineered boards, others for vinyl or LVT, and some work across multiple floor coverings. The condition of the subfloor also matters: it should be clean, dry, and free of dust, grease, or old adhesive residue before application. Using the wrong adhesive or applying it to a poorly prepared surface is the most common cause of flooring failures.
Felt adhesive is a solvent-based bonding product used to bond roofing felt to timber decking, typically on flat or low-pitch roofs, sheds, and outbuildings. It is applied to both the decking surface and the underside of the felt before pressing together. Most felt adhesives are suitable for DIY use, but working at height carries risk, so appropriate safety measures should always be taken. Pay attention to temperature guidelines on the product: felt adhesive often requires a minimum ambient temperature to bond correctly, and should not be applied in wet or frosty conditions.
