Block Paving Cleaning

Process: 1. Pressure wash the block paving clean, removing all the old sand from the joints and any grease stains and algae growth. Surfaces should be completely dry and free from contamination before the sealer is applied. 2. To re-sand the block paving joints and empty the contents of one bag of sealing sand on to the treatable area and carefully sweep in between the blocks, ensuring all the grout joints are filled to the brim. 3. To seal block paving, apply PICSEAL acrylic sealer evenly over the surface using a pressurised sprayer. Proceed to spread the block paving sealer using a soft coconut fibre broom making sure all the grout joints are covered. 4. Allow block paving sealer to dry. This usually takes two hours to be touch dry. CDS Ltd recommends keeping vehicles off of the surface for a further three days to ensure the best finish.
