Professional Multiblock Primer
WALLMASTER PRO Multi-Block Primer is a water-based sealer and undercoat. It is a versatile product used during new construction and renovation to seal and prime different trim and door materials installed during second fix carpentry and joinery. Multi-Block eliminates the need for multiple sealers, primers and / or undercoats to ensure correct adhesion, fill and gloss hold out of the final trim finishes. It resists tannin and knot bleeding especially from tropical woods. It minimises grain-rising in bare timber and bare MDF and is highly resistant to water stain bleeding. The multi substrate adhesion compatibility and stain bleed performance of Multi-Block affords the applicator the convenience of only a single product required to prime, seal and / or undercoat all door, door jams, skirtings and architraves making it the ideal preparation coat for use during new construction and home renovation.
