Mathys Porisol can be applied undiluted on very porous substrates (cardboard, paper, light kinds of woods), and diluted on substrates with different absorption capacity (plaster, wood-fibre boards, etc.). It can be used as a sealer undiluted on exotic wood, aniline colours and surfaces soiled with coaltar. Do not apply on substrates soiled with fume residues or soot (isolate first with Pegamat).
