Selecting the right paint primer is often the difference between a professional-looking finish and a paint job that peels or stains. Whether you are tackling a high-traffic area or restoring old woodwork, the choice of base coat depends entirely on your surface material and the current state of the substrate. Our selection focuses on versatility, drying speed, and the ability to block stains and seal porous materials effectively.

Frequently Asked Questions

AI
While some modern paints are 'all-in-one' products, a dedicated primer is essential for porous surfaces like new plaster, highly absorbent wood, or when making a drastic colour change to reduce the number of topcoats required.
A primer seals the surface and provides a 'key' for the paint to stick to, while an undercoat is primarily used to create a smooth, even base and build the surface for the final decorative layer.
For metal surfaces, look for primers specifically labelled as 'anti-corrosive' or 'metal primers' to prevent rust and ensure the paint doesn't flake off over time.
Sash-blocking or stain-killing primers are designed to prevent old water marks or nicotine stains from bleeding through the final paint layer.
