Murfill Waterproofing Coating for Exterior Masonry
Murfill Waterproofing Coating is an extremely effective and durable paint for exterior masonry walls and facades. The tried and tested coating is 100% waterproof, 400% elastic and will protect the masonry against all weather conditions.
The micro-porous structure ensures that the base is constantly able to breathe, and that moisture will not get trapped. Additionally, the enhanced elasticity ensures that the coating can move with the masonry and will not crack, peel or blister.
The Murfill Waterproofing Coating also has excellent crack bridging properties, and can be applied to sound surfaces with surface cracks. Alternatively, for surfaces with larger or more active cracks, combine with the Murfill Fleece for additional reinforcement.
Also with additional colour fast properties to ensure that colours will stay brighter for longer and will have excellent resistance against aging. At HSP we can tint the Murfill Waterproof Coating to any colour from any colour card.
Properties of the Murfill Waterproofing Coating:
- Ready to use and simple to apply
- 400% Elastic
- 100% Waterproof
- Water vapour permeable
- Excellent resistance against ageing
- Protects reinforced concrete against carbonisation and corrosion
- Can be combined with Murfill fleece for additional mechanical reinforcement and for bridging of (active) cracks.
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 stabilising solution.
New or unpainted substrates:
On porous materials apply first a coat of Primer 44HS.
On smooth non-porous substrates apply a coat of Pegalink white or a coat of Noxyde (except for white) diluted with 25% water.
Cracks < 0.5 mm wide: fill with Murfill Waterproofing Coating.
Cracks > 0.5 mm wide: fill with Elastofill
Active movement cracks need to be bridged with Murfill fleece.
