APPLICATION DETAILS
Application conditions
The surface to be painted must be clean, dry and solid and the temperature of the air and surface at least +10 °C and the relative humidity of the air below 80 %.
Preparation
Unpainted surfaces:
New concrete, screed and plastered surface must be sufficiently dried and hardened before finishing treatment.
Clean unpainted surfaces from dirt, dust and other impurities.

Previously painted surfaces:
Clean surfaces from dirt, dust and other impurities. If necessary, clean with Tikkurila Maalipesu Cleaning agent according to instructions. Remove flaking and poorly attached or powdery paint layers.
Patching
Patch cracks, holes and dents so that they are in the same level with the surrounding surface. Use an appropriate dry filler on concrete surfaces and lime plaster or lime cement plaster on plaster surfaces. If necessary, patch paint smoothed areas with Muuri Fireplace paint.
Painting

Apply one priming coat of Muuri Fireplace paint. The product can be thinned with water up to 10%, if necessary. After the primer has set for at least 12 hours, finishing coat will  be applied. 


Note!

Cover surfaces that will not be treated, such as windows, natural stone or clinker-tiled surfaces and metal surfaces. Remove any paint spatter immediately with water.

The variable porous structure of the surface to be painted and moisture and temperature variations during paint application and drying may cause diversity of color.

 

It is recommended to wait for at least two weeks before the treated surfaces are taken into use so that the product can reach the heat durability requirements set for it.

 

Mechanical strain may cause visible marks on the painted surface. This is a typical product feature of matt paints; however, it does not affect the technical functionality of the product.

Cleaning of tools
Clean tools with water. Tikkurila Tool Cleaner is recommended for removal of hardened paint.
Maintenance instructions
If necessary, clean the surfaces with a dry brush, mop or dust cloth after a month of the surface treatment at the earliest.
Maintenance treatment
Surfaces painted with Muuri paint can be maintenance painted with the same product.
