Surface Preparation

Surface must be free of oils, grease, loose particles, dirt, mould, moss or other foreign matter. Murobond advises application by a recommended contractor.


Stir product thoroughly before application. Porous surfaces: thinning should be minimized = 5% or less clean water.

Non-porous surfaces: thinning should be avoided.

Second or subsequent coats: thinning should be avoided.


Apply even full thick coats working quickly to maintain a wet edge across each surface.


Airless spray is recommended with care to fully mask surrounding surfaces against overspray. Allow overnight drying between coats.




Mineral Silicate Matt Clear will react and chemically combine with mineral surfaces including glass. Mask these surfaces thoroughly and clean up spills, spatter, and overspray immediately.
