Johnstone’s Ultra Primer Sealer is a high-performance, quick-drying, alkali-resisting primer sealer formulated from a tough acrylic resin with stain-blocking properties. It primes and seals plaster, plasterboard, cement render, timber, bare masonry, interior stone and fibre cement boards, wood panelling, ceramic and glazed tiles, doors, trim, windows and any surface where excellent adhesion, fast drying, stain-blocking properties are needed.

Applying Johnstone's Trade Ultra Primer Sealer

For best results use a brush or airless spray to apply 1 coat to a clean, dry surface. If priming a bare surface or porous surface, apply a sealing coat thinned by up to 20% water before applying 1 full coat afterwards. Follow with your chosen topcoat.
