  • 400% Elastic - The permanent elasticity protects your exterior wall optimally in all circumstances and prevents tears, flaking and blistering.
  • 10 Year Waterproof Guarantee*
  • Water vapour permeable - Murfill Waterproofing Coating allows the substrate to breathe at all times.
  • Crack bridging - Excellent resistance against ageing and contamination in all weather conditions and climates.
  • Protects reinforced concrete against carbonisation, penetration of chlorides and corrosion.
  • Colourfast - The unique Murfill formula means that even deep and dark colours are not affected by sunlight.
  • Water based - Low odour, minimal VOC's and environmentally friendly.
  • Can be combined with Murfill fleece for additional mechanical reinforcement and for bridging of (active) cracks.

Rust-Oleum Mathys Murfill Waterproofing Coating can be applied directly on old (sound) paintwork after thorough brushing down. Chalking paints or new/unpainted substrates must be treated first with Rust-Oleum Mathys Primer 44 HS or with Mathys Pegafix, when the old paint coat (acrylic paint or Murfill Waterproofing Coating) is affected by the solvents of Rust-Oleum Mathys Primer 44 HS. On smooth non-porous substrates apply a coat of Rust-Oleum Mathys Pegalink Universal Adhesion Primer or a coat of Rust-Oleum Mathys Noxyde (except for white) diluted with 25% water.

Can I use Murfil waterproof paint on interior shower walls?

Graham Patient from Shrewsbury (UK) - 12/08/17



I want to use Murfill on concrete as the previous paint has peeled off, what primer should I use, the site is exposed and near the coast. Thank's

Richard Ward from Cork (Ireland) - 11/06/17

New or unpainted porous substrates should be primed first with a coat of Rust-Oleum Mathys Primer 44 HS or Mathys Pegafix.

I can't find the details of how long I need to allow for the paint to dry before it is waterproof and safe to be rained on. Just trying to plan around the weather! Data sheet only mentions handling time and recoat time, but no mention of waterproof time. If you'd be able to let me know, that would be great.

Matt Stocker from Coventry (UK) - 17/09/16

When the full specified system has been applied (usually 1 x primer and 2 x Murfill Waterproofing Coating) and the final paint layer has dried sufficiently as per the Product Data Sheet (usually 24 hours at 20°C) then the system will be providing waterproof protection of the building.

In good drying conditions (20°C/50% R.H.) then Murfill Waterproofing Coating should be 'rain proof' after 6 hours. Please note that fluctuations in weather/conditions/temperatures/etc. will affect these estimates greatly.
