FAQ

How many coats of skim coat are needed?

Typically 2-3 thin coats (0.5-1mm each), with light sanding between coats. Apply each coat after the previous one has dried.

Can skim coat be applied directly to concrete?

A plaster base coat or primer is usually recommended before applying skim coat to bare concrete to ensure proper adhesion and an even finish.
