Excellent product and service

By Carl Russell

Had to clear a lot of weeds and resand cobblelock. The sand is now sealed as hard as concrete, very happy with this product.

By Carl Russell

Like most people I wasn't sure which would be the best sealer. I have just finished cleaning / resanding a driveway and used smartseal matt finish, exactly as instructed. It rained a few hours later but I could see the joints were completely water resistant. Delighted with this product, and now two neighbors have asked if I can resand and seal their driveways. I highly recommend this product, but you must follow the instructions.

Product Description

s Block Paving Sealer in Matt Finish

Cobblelock Driveway Sealer for Brick Paved Driveways 

Smartseal Block Paving Sealer MATT finish has been specially formulated to help prevent weeds growing on block paved surfaces. It also provides greater levels of stain resistance from oil, dirt and grease. The cobblelock driveway sealer MATT hardens sand in the joints and helps prevent weed growth. The brick paving sealer MATT can be applied easily by sprayer or roller.

It will seal block paving and make it non-porous, this will make the block paved driveway or patio easier to clean and maintain.The sealed surface of the block paving will help to prevent the erosion of the jointing sand and help to provide a barrier to any surface contaminants facilitating easier ongoing maintenance.

Recommended coverage rates for application
First coat: 2.0sq metres per litre
Second coat: 3.5sq metres per litre



Smartseal Block Paving sealer can be applied using a sprayer unit or roller, at a rate of 2.5m2 per litre (pavers) 1st coat & 3.5 m2 per litre 2nd coat. A two-coat spray application is required to fully cover the jointing sand. The sealer will be tack free within 2 hours at 20°C and foot traffic may be permitted after 4 hours. Vehicles should be kept off the sealed area for a minimum of 24 hours at 20°C. These times may be increased or reduced depending on the ambient temperature. During the curing cycle, protect from rain. Do not apply when the ground temperature is above 30°C or below 5°C. All equipment should be cleaned with Smartseal tool cleaner after use.

Deicing salts should not be applied directly on Smartseal block paving or concrete sealers. Salt chemically reduces the temperature at which water freezes and will result in water ingress into the concrete. Subsequent freezing may result in the concrete ‘seal’ being broken by the expansion of water as it freezes and white ‘pitted’ areas may become visible.



New block paving or cobble stone paving should be swept clean, ensuring there is sufficient well-compacted sand in the joints. Existing paving should be pressure washed to remove all surface debris. If the area is contaminated with weeds & moss then it should be treated with Smartseal Fungicidal Wash. Oil and other stains should be removed using Smartseal Cleaner / Oil Remover. The treated area should then be left to dry and the joints re-sanded & compacted to the lower edge of the paver chamfers with clean kiln-dried sand. Moisture in the paver & sand will inhibit penetration of the sealer and produce whiteness.
