Finivlam needs to be applied with low pressure to the surface. You can use a Compression
sprayer (see the picture below). During the drying process (which lasts about 6 hours)
the product will form a paste towards the surface and creates an almost invisible
protection layer. Some shrinking might be the result of using the product, which
depends on the quality of the fibres used for impregnating. The treatable surface
must be colour proof and absorbent.
