What does a primer sealer undercoat do?

Use before topcoating to improve adhesion, coverage and finish consistency. It helps seal porous surfaces and create a smoother base for paint by filling minor imperfections. This premium water-based undercoat provides excellent opacity, reducing the number of required topcoats and saving time and material costs.

Suitable surfaces

This adaptable formulation bonds perfectly to a wide variety of substrates. It provides a reliable anchor layer for:

• Bare wood and timber trims
• Previously painted wood surfaces
• Plasterboard and interior plaster walls
• Concrete, brick and masonry blocks
• High-traffic interior surfaces and exposed exterior surfaces

When should you use a separate metal primer?

While this primer sealer undercoat handles most surfaces, specialised substrates require tailored solutions. If you are dealing with ferrous metals or active corrosion, explore our range of undercoats and primers. For raw steel, always treat the surface with Viponds acrylic metal primer before applying topcoats.
