RustOleum Murfill Waterproofing Coating for Exterior Walls and Facades

Use the Murfill Waterproofing Coating to paint all exterior masonry walls and facades to protect them from all weather conditions. Ready for use and easy to apply to most masonry surfaces, Murfill Waterproofing Coating is perfect to paint your exterior masonry. 

400% Elastic and 100% Waterproofing, the Murfill Waterproofing will move with your masonry and so it will not crack, peel or blister. Additionally, the micro-porous structure will ensure that the masonry will be able to breathe, and moisture will not get trapped underneath. 

Murfill Waterproofing Coating also has exceptional crack bridging properties. Apply to sound surfaces with small or hairline cracks. Or, for larger, more active cracks use with the Murfill Fleece for additional mechanical reinforcement.

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.

Active movement cracks need to be bridged with Murfill fleece.
