DRYWOOD Firestain is a water-borne low-film building stain for non-dimensional stable applications such as exterior and interior wood constructions, sidings, claddings, or facades treated with a fire-retardant treatment according to EN 13501-1 class B and C.

Drywood Firestain 079000-00 can be applied by all conventional spraying systems - both hand spraying and automated spraying systems - and by vacuumcoater, brush or roller. Drywood Firestain 079000-00 will typically be applied as a primer, intermediate and topcoat on substrates such as softwood and modified wood. All softwood and non-durable hardwood for exterior use should be treated with a wood preservative. Compatibility between the fireretardant impregnation and Drywood Firestain 079000-00 should be tested prior to application.

DRYWOOD Firestain gives good colouration of the wood with translucent colours. For semi-opaque colours, the wood structure is less visible. The product has good penetration into the wood, shows good adhesion, and builds a thin film layer in two or more layers. The product is water repellent and does not chalk off.

Surface preparation

The surface to be treated must be clean, dry, sanded, and free of dust and grease.

Application conditions

Stir thoroughly before use. The product should be used above 8°C with maximum 70% relative humidity. Typical use on a planed surface is 70-80 g/m² for the first coat and 60-70 g/m² for a second coat. Typical use on a sawn surface is 120-130 g/m² for the first coat and 70-80 g/m² for a second coat. Check colour before use. Wood should be dried after fire-treatment and any excess fire-retardant chemicals should be removed from the surface prior to application of the coating.
