GLOSSARY TERM
Undercoat
A layer of paint applied before the topcoat, often used to build up thickness and provide a smooth surface.
INFO
What it is
An undercoat is a layer applied between the primer and the topcoat. It builds up the coating system, helps even out the surface, and provides a sound base for the finish.
Why it matters
The undercoat improves the depth, uniformity, and durability of the system and helps the topcoat achieve an even colour and appearance. It is part of building a finish that lasts.
Where it is used on a project
Applied as part of a multi-coat build on surfaces where an even, durable finish is wanted, after priming and before the topcoat.
How NECC approaches it
We build coatings in the correct sequence, applying undercoats where the system calls for them, so the topcoat sits evenly and the finish is hard-wearing.

FAQ's
What is an undercoat?
It is a coat applied between the primer and topcoat to build the system, even out the surface, and improve the final finish.
How is it different from a primer?
A primer bonds to and seals the substrate; an undercoat builds the system and prepares an even base for the topcoat.
