Adhesives & Primers

Primer and adhesive for underfloor heating floors

Floor preparation is the step that's easiest to rush and hardest to put right later. Priming the subfloor and bonding boards properly keeps tiles, levelling compound and heating systems firmly in place for the life of the floor.

Ultra Prime IT multi-surface primer.

• Use it before tile adhesive or levelling compound goes down.
• On porous surfaces such as sand and cement screed, concrete and plywood, it seals the surface so the adhesive or compound doesn't dry out too quickly and lose strength.
• On smooth or non-porous surfaces, it improves the key.
• One 5 litre container covers a large area.

Tuskbond FD170 spray contact adhesive.

• A fast, mess-free way to bond insulation boards, foil and membranes to the subfloor.
• There's no mixing or trowelling, and the bond is quick.
• It's a handy alternative to adhesive beds when you need boards held in place while you work.
