The application cycle provides the following procedures:
1) PREPARATION OF THE SURFACES
Verify that the materials to protect are free of grease, fats, oil, waxy impregnating and preesisting varnishes. Existing paint coats must be removed by sandblasting or by sandpapering with coarse grain and then fine abrasive paper at naked wood.
After this operation, in order to ensure maximum adherence of fire-retardant paint on the support, carry out further cleaning using a dampened cloth with nitro thinner to remove completely from wood traces of wax.
It should be checked carefully that the humidity of the wooden materials to coated is less than the value of 12% in weight.
If the conditions of preparation above indicated are not respected, we don’t give any guarantee of durability of treatment.
2) FIRE RETARDANT IMPREGNATING AGENT
Application of three or more coats of STARWOOD A. F.1 for a total consumption of applied product equal to 500 g/m2.
