StoneCoat Hydraulic Limestone Veneer

The process. StoneCoat is a natural, hydraulic limestone that is crushed, mixed with a proprietary binder and spray applied to any surface (other than vinyl, aluminum or steel siding) and hand carved to match any stone, brick, block or river rock design you can imagine. This quarried stone is crushed to a powder, and then re-bonded with water.

Why We're Fixing Our Stone Foundation with Hydraulic Lime Mortar

The beauty of lime mortar is that it allows the stones to "breathe" and "flex". Bricks of the 19th century through to even the 1950's are more porous than today's bricks. Stones are naturally porous as well. Lime mortar has the amazing ability to keep the structural integrity of your brick or stone walls because it is also porous.
