Problem Solver - Concrete Block
Concrete blocks are made from cast concrete, e.g. Portland cement and aggregate, usually sand and fine gravel for high-density blocks. If left untreated, the surface can degrade.
Stage 1 - Preparation
Dry brush the surface down using a stiff bristle brush to remove any loose materials
If any mould or mildew is apparent, treat with a suitable fungicidal solution, rinse again with clean water and allow to dry.
