The masonry brickwork is complete. The remaining material is the cementboard. There are a few steps that need to be done before we can attach the cementboard. The concrete blocks must first be sealed with a liquid primer. This ensures that the surface is dust free so that the perma-barrier (the black material) can adhere to the concrete block. Metal furring strips are anchored and caulked. Metal furring strips receive a rubber gasket that is sandwiched between the exterior fiber cembentboard and metal furring. The cementboard is predrilled and fastened with stainless steel screws with matching colored heads. Hopefully the weather holds up.
