LTP Blackstone Water-Based Impregnating Sealer for Stone Paving

Dark coloured paving often fades or discolours over the years which can make your patio look tired and worn. Bring it back to life with LTP Blackstone Sealer and Restorer - it can be used to restore the appearance of all types of faded dark natural and artificial stone including limestone, marble, slate and concrete pavers.

Each 1 litre bottle covers up to 30m² in a single coat.

Important: This product is a permanent staining solution that will darken the surface of the stone and the grout joints making it very difficult to remove once applied. Test on an inconspicuous area before general application and do not walk on treated surfaces until the solution has completely dried.

Does exactly what it says! My paving slabs are 600x900. I poured a cup full on each slab and spread it around. It easily covers the m2 quoted.
