Substrate Preparation:

Substrates should be sound & rough to ensure a good bond. They should be uncoated & clean, free from all contaminants, loose particles, dirt, oil, mould, curing compounds, sealers & paints etc. Acid washing, rough honing or scabbling & then water blasting is required to prepare concrete surfaces depending on substrate condition. Washing with soap & water blasting may also be required if oil is present. The better the substrate preparation & condition the better the end result.
