NP Keycoat is a high performance, water based, modified polymer primer. Supplied ready to use it is formulated for use on smooth and non-porous, demanding substrates prior to tiling or levelling. It is ideal for priming one coat DPMs, tiled floors and metal substrates. NP Keycoat can also be diluted for use on porous substrates as a general purpose primer to reduce the absorption of the substrate before applying tile adhesives and levelling compounds.

Prep: Substrates must be sound and dry, clean and free from loose material or contamination which will effect the bond. All sub floors should be over 28 days old, Gypsum screeds must be below 0.5% moister content and free from surface laitance. Timber must be sound and stable. The ambient temperature ust be above 5c when the primer is applied and underfloor heating must have been turned off at least 48 hours before.
