A mist coat is a diluted first coat of matt emulsion paint applied to newly rendered fireplace chambers before the final paint coats. It helps seal the surface, reduces suction, and creates a good base for paint adhesion.

Prevents peeling and flaking

Helps paint bond properly to fresh render

Creates a smooth, uniform finish

Reduces patchy top coats

Improves durability and longevity

The ideal time to paint is before the stove is installed, when access to the chamber is easier.

Use a good-quality matt emulsion paint (avoid silk, satin, or gloss).

Mix approximately 70% paint and 30% clean water.

Stir thoroughly.

Apply evenly with a brush or roller.

Let it dry completely (typically 2–4 hours, depending on conditions).

Apply one or two full-strength top coats.

A properly applied mist coat is essential for achieving a professional, long-lasting finish on a newly rendered fireplace chamber, and it's much easier to complete before the stove is fitted.
