Apply two coat of sealer - For optimum results apply the Polyurethane block paving sealer at a ratio of approx 2sq metres per litre 1st coat and 3.5sq metres per litre 2nd coat. Apply second coat within four hours to ensure sealer 'keys' together correctly.
Urethane based block paving sealer is only to be used on precast concrete block pavers and cannot be used on any other form of paver, brick, patio slab, natural stone or block pavers finished with a top course of natural aggregate. *NOT TO BE USED ON CLAY PAVERS*
- Only apply sealer when the block paving is clean with jointing sand and paver totally dry with no rain forecast for at least 8 hours.
- Temperatures need to be above 10 degrees centigrade and below 25 degrees.
- Only apply if no efflorescence (surface salts) is visible
- Make sure pavers are thoroughly swept and that no jointing sand remains on the surface or high in the chamfers of the blocks. This could lead to unsightly sand becoming sealed onto the surface of the blocks
- Apply to borders with a paint brush or small roller.
- Application to main areas by roller or squeegee at ratios of 2sq metres per litre 1st coat and 3.5 sq metres per litre 2nd coat
Leave between 2-3 hours and no more than 4 hours between coats
