What is a primer, and why and when should you use it?

A primer is a coating applied directly to the surface before the final paint finish.

Its purpose is to penetrate the surface pores, seal and protect the substrate, improve water resistance where required, and ensure strong adhesion with a smooth, uniform final result.

Choosing the right primer plays a key role in extending the life of the paint system and helps prevent issues such as peeling, uneven coverage and reduced adhesion.
