Fresh plaster, cement render and new masonry can contain residual alkalinity that may attack standard paint films. This alkali resisting primer forms a protective barrier, helping to safeguard topcoats from degradation and discolouration.
It is particularly recommended where surfaces have not fully cured or where long-term durability is essential.
By sealing porous substrates and reducing surface absorption, this primer supports improved coverage and performance of emulsion and masonry paints. It helps create a stable, uniform base that enhances the overall lifespan of the decorative system.
Recommended for use on:
New plaster
Cement render
Concrete
Brickwork
Bare masonry surfaces
Allow new plaster and render to dry adequately before application in line with best practice guidelines.
Ensure surfaces are clean, dry and free from dust or loose material. Stir thoroughly before use and apply evenly with a brush or roller. Allow sufficient drying time before applying finishing coats.
For large-scale preparation of new or alkaline masonry surfaces, this 5L primer provides dependable sealing and long-term protection. It is an essential first step in achieving a durable, professional decorative finish on interior and exterior walls.
