Block Paving Sealers
Choose the sealer specified for your paving material and desired appearance. Wet Look and Matt are different finish choices; natural stone and block paving must not be treated as automatically interchangeable.

Start with Extreme Seal Wet Look Block Paving Sealer – Matt option available. For sandstone or limestone, check the separate product's suitability rather than using collection membership as approval.
Compare driveway and patio sealers and patio-cleaning products. See the paving-sealer finish guide.
Check before application
For the Extreme Block Paving product, the approved rate is 6–8 m²/L per coat: 5L covers 30–40 m² per coat. Calculate every required coat separately; actual use depends on the surface. Follow its preparation, new-paving waiting period and drying guidance. Sealing is not a guaranteed weed/moss treatment, waterproofing repair or fixed-life promise.
