Description

ADESIV PRIMER WB PU — 10 kg

Solvent-free, monocomponent 100% polyurethane consolidating primer for absorbent subfloors. Fast-drying, odourless, and rated EC1 PLUS (very low emissions). Acts as a moisture-repellent barrier on substrates with residual humidity up to 4–5% and is suitable over underfloor heating/cooling systems.

Where to use

Absorbent flooring and traditional concrete screeds
Anhydrite (calcium sulphate) screeds
Heated or cooled subfloors (UFH)
As a consolidating base prior to levelling and bonding

Why it works

Consolidates friable surfaces for a stronger, more uniform base
Cuts suction so levellers and adhesives behave predictably
Low odour, solvent-free for occupied sites and indoor work

Application notes (straight talk)

Mechanically prepare the subfloor; it must be compact, clean, and dry to spec.
Check moisture — this primer is a barrier only up to 4–5% residual humidity; it’s not a cure for a wet slab or missing vapour barrier.
Apply the first coat uniformly. On very absorbent areas, apply a second coat within 12 hours.
If you’ll be levelling, broadcast 0.1–0.3 mm quartz sand into the last coat while fresh; after ~2 h, vacuum excess and bond within 24 h.
Clean tools with GR7 before the product sets.
