Surface Preparation

Murfill Waterproofing Coating can be applied directly on old (sound) paintwork after thorough brushing down. Chalking paints or substrates must be treated first with Primer 44HS or with Pegafix, when the old paint coat (acrylic paint or Murfill Waterproofing Coating) is affected by the solvents of Primer 44HS. Newor unpainted substrates: on porous materials apply first a coat of Primer 4HS or Pegafix. On smooth non-porous substrates apply a coat of Pegalinkwhite or a coat of Noxyde (except for white) diluted with 25% water. Cracks < 0.5 mm wide: fill up with Murfill Waterproofing Coating. Cracks > 0.5 mm wide: fill up with Elastofill or Mur-Filler. Active cracks must be bridged with Murfill fleece.


To ensure homogeneity, coating materials should be thoroughly stirred prior to use
