Wethertex PP1 Pre-Prep Wash Coat Primer is a ready mixed, flexible, through coloured penetrating primer to control suction and ensure good key, prior to the application of MP44 Spray Wall Coating or AX1 Pliolite Thin Coat Render.
Suitable substrates include GRC, X71, Bonded Paint, Dash, Roughcast and Render.
All surfaces must be sound, clean, dry and free of any material which may impair adhesion. Scaffolding must be independently-tied to allow for uninterrupted application. Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified.
Mixing
PP1 Pre-prep Primer is supplied ready to use, but may need re-mixing using a suitable paddle mixer to regain correct consistency for application.
Application
By roller – submerge the roller totally in the primer to ensure that the roller is fully loaded with material to allow even application without spreading too thinly.
