For maximum performance on new block paving and paving slabs, ensure blocks or paving slabs and jointing sand are dry. In order to avoid dislodging the sand, it should be well compacted and slightly below the level of the block or paving slab. For existing block paving and paving slabs ensure all surfaces are clean, dry and free from grease, oil, dust or loose material that may interfere with the penetration of the sealer to be applied. Dirt, moss, lichen and other loose material can be removed using Thompson's Patio & Paving Cleaner. Grease and oil stains can be removed using Thompson's Oil & Drive Cleaner. Rinse thoroughly with water to ensure all cleaning residues are washed away. Brush area to be coated to remove all surface debris. Allow to dry thoroughly.


Thompson's One Coat Patio & Block Paving Seal can be applied using a long pile roller and a roller tray or a brush. Surfaces should be dry before application. Apply an even coat to ensure all surface irregularities are covered. Attention should be paid to textured block paving slabs to ensure the surface is evenly coated and that the coating does not 'pond' in surface depressions. Brush well into the surface redistributing any surplus product. Extremely porous surfaces may require more than one coat. Light traffic is acceptable after 4 hours. However, Thompson's One Coat Patio & Block Paving Seal does not reach its optimum performance until after a few days and should be left overnight before vehicles can be parked on treated blocks or before subjecting the area to heavy duty use. In cold, damp conditions drying and recoating times will be extended.

Clean Up

Clean brushes, rollers and other equipment immediately after use with white spirit or brush cleaner. Remove as much product as possible from application equipment before cleaning.
