Good trial size Product, only needed a small amount of sealer to match some old block paving with new blocks, colour was a bit blue so i mixed in a little black colourant and got a perfect match for the darker looking blocks. very pleased with results.

By Peter Rice From Rayleigh

Excellent products well impressed. The Xtreme Drive Cleaner did what it said on the tin, cleaned the blocks and removed weeds and algae from just need to jet wash. Two coats of block magic grey on red and grey block paving covered really well, even before the clear sealer; passers by and neighbours already commenting on how good the drive looked. Fast forward to sand and clear sealer on this has totally transformed the driveway. No need to go to the expense of a new driveway these combined products makes and old blocked paved drive look new. Unfortunately I did not take any before photos but happy to shared after photos if anyone is interested

Quick delivery. Ordered a sample of the sealer to test the colour output Easy to apply good coverage and good shade of grey not too dark or light will look to do the driveway now

By Carl Barron

Just used this sealer today on my block paving. Very easy to apply, Does need a second coat, but that could be down to my application rather than the product! Looks good though.

By Terry McHugh From Newcastle

Bought the sample seal to see how it would look on our drive and must admit we are very impressed with the look it will bring once we are able to do the entire drive once the 25ltr tins come back in to stock, very impressed

Add colour to your block paving to make it look like new.

Smartseal "Block Magic" is a blend of liquid pigments and acrylic resins that soaks deeply into paving, totally transforming and protecting block paving driveways and patios. 'Block Magic' replaces the colour that sun, rain, vehicles and pressure washing has taken away. Apply one coat of 'Block Magic' by brush or roller, leave to dry, re-sand the joints and then apply a coat of our clear sealer.


 Transforms Old Block Paving

  • Recolours and Protects
  • UV Stable
  • Colour Fast
  • Stain Resistant
  • Hard-wearing
  • Covers 3 m/litre on average based on one coat
  • Other Colours Available

See Technical section below for more information.


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 3.0m per litre. Make sure the colour has dried evenly across the block paving before applying 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 20C and foot traffic may be permitted after 4 hours. Vehicles should be kept off the sealed area for a minimum of 24 hours at 20C. 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 25C or below 12C.
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.


*** If your Block Paving has been previously sealed - to ensure compatibility, please contact us here before ordering: https://www.smartseal.co.uk/help-advice/contact-us.htm

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.
