DRYWOOD FIRESTAIN

This product is an industrial primer and topcoat designed for exterior wooden elements and prefabricated units in wooden house construction. The coating may be applied to timber that has been fire-retardant (FR) impregnated with boron-based formulations.

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.

The coating itself does not provide any fire retardant properties. FR impregnations differ significantly from FR coatings. Teknos does not hold test evidence or documentation supporting the use of this primer over FR impregnated timber. Therefore, Teknos disclaims all liability regarding aesthetic appearance, performance, and weathering of the product when applied over FR impregnated substrates. DRYWOOD FIRESTAIN protects the wood until it is top coated at the building site or in the factory. The top coating should, however, be done as soon as possible, the next summer at the latest. Before use, the manufacturer or technical service department should be consulted to confirm the product’s suitability for the specific substrate, coating system, and exposure conditions.
