Preparation

Ensure all surfaces are clean, dry and properly prepared before painting. Apply only when the ambient temperature is above +10°C and the relative humidity is below 80%.

Unpainted Surfaces

• Allow new concrete, screed and plaster surfaces to fully cure and harden before painting.
• Remove all dust, dirt and other contaminants to ensure good adhesion.

Previously Painted Surfaces

• Clean thoroughly to remove dirt, dust and surface contaminants.
• If required, wash with Tikkurila Seinäpesu Cleaning Agent following the manufacturer's instructions.
• Remove any loose, flaking, poorly adhered or powdery paint.
• Sand glossy painted surfaces to create a matt finish and improve adhesion.

Repairs

• Fill cracks, holes and surface imperfections so they are level with the surrounding area.
• Use a suitable filler for concrete surfaces and appropriate lime-based products for plaster substrates.
• Allow repairs to dry fully before painting.
• If necessary, spot-prime repaired areas with Muuri Fireplace Paint.

Protect all adjacent surfaces that are not being painted, including windows, natural stone, clinker brick and metal surfaces. Remove any paint splashes immediately with clean water.

Please note that variations in substrate porosity, moisture levels and application or drying conditions may result in slight colour differences across the finished surface.

Application

Always test a small area of the surface to be painted to ensure you are happy with the finished results.

• Use a brush or limebrush for best results.
• Apply 1 coat of Muuri Fireplace Paint as a primer.
• If required, the paint can be thinned with up to 10% clean water.
• Allow the primer coat to dry for at least 12 hours.
• Apply the finishing coat once the primer has fully cured.

Always follow manufacturer's instructions found on the packaging

Note: If using more than one tin of the same colour, intermix prior to use to ensure colour consistency. Check tinted product before application to avoid colour differences.

Aftercare & Storage

Allow the painted surface to cure for at least two weeks before use to ensure it achieves its full heat-resistant properties.

If required, clean the surface after one month using a dry brush, mop or dust cloth. As a matt finish, Muuri may show visible marks from mechanical contact, which is a normal characteristic and does not affect its performance.

For maintenance, surfaces can be repainted using the same Muuri paint.
