- Ensure that the surface to be worked on is clean, dry and free from dirt, dust, grease and other contaminants. If you are washing the area first then allow it to dry thoroughly before applying Block Paving Sealer. If you have moss, algae or other fungi then it should be treated with a suitable algicide or fungicide.
- If there has been some sand loss, top up the joints between the blocks with clean, dry sand up to the chamfered top
- Apply Block Paving Sealer with a brush or roller and don’t apply too thickly. Don’t allow the product to puddle in the joints or on the surface of blocks.
- Only take as much product as you need for a working quantity before re-sealing the tin to stop moisture vapour getting to the mixture.
