Customer Reviews

I had the old red/grey block paving in front of my house. Those colours went out with the indians. I repainted with black smartseal. Excellent job. Half the street were asking me questions about it. When dry, just use a clear sealer to protect it. Very happy with this product and would recommend.

After using > 50+ litres of "Block Magic" (black) and then a subsequent coating of clear sealer on a driveway & paving in front of my house, in terms of finish, it has transformed the entire area. The sanded joints remain fixed and the paving block surface looks brand new.. Absolutely delighted with product & service........

'Block Magic' will restore the colour and protect brick paving on driveways and patios

Smartseal 'Block Magic' is a formulation of  UV resistant liquid pigments and acrylic sealing resins. It restores the original colour to old cobblelock driveways by penetrating into the block paving and replacing all the lost colour. One coat of 'Block Magic' followed by a 2nd coat of clear sealer will transforms all forms of block paving and leave sanded joints solid and resistant to weeds. 'Block Magic' is colour fast and guaranteed against colour loss for 5 years.

The colour restorer for cobblelock driveways can transform the look of your home by adding colour to the brick paving. UV light and general wear and tear can make cobblelock driveways and patios look old over time. Block Magic can transform the old brick paving to look like new.

***Always apply to test area first***


Liquid UV stable pigments blended with acrylic resins and solvents create "block magic". Developed by Smartseal with older block paving in mind, it will not only recolour block paving but protect the paving from future colour loss, weeds algae and staining.

'Block Magic' Coloured Paving Sealer is applied by roller, at a rate of approx 3.0m2 per litre. Make sure the colour has dried evenly across the block paving before appying a clear second coat of sealer.Prior to applying sealer, sweep kiln dried sand into the joints and ideally compact with 'wacker plate'.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.
Ensure no rain is forecast for at least 6 hours after application. Do not apply when the ground temperature is above 30°C or below 10°C.
All equipment should be cleaned with Smartseal cleaning fluid after use.

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


Existing paving should be pressure washed to remove all surface debris and muck from the joints.
If the area is contaminated with weeds & moss then it should be treated with Smartseal moss clear or weed killer.
Oil and other stains should be removed using Smartseal Driveway Cleaner or 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.
