Product Reviews
By Arpen PatelFROM London

We moved about 8 years ago and renovated the whole house but the drive was the only thing left to do. The block paving had faded with marks and the regular moss and weeds coming through, we were going to replace it which would have cost around 7k. I then came accross the Smartseal product and after cleaning the original paving and sealing it with 2 coats the drive looks amazing, neighbours have complimented how nice it looks, I was worried the seal wouldn't look natural and add a layer of paint that made the block paving look fake, the seal actually soaks in the block paving and keeps the texture and feel of a new blocking paving block. I have saved thousands of 's by colour sealing the drive and would recommend this product to all thinking about refreshing the look of their drive.

By Dave Hardie

I was a little apprehensive about how the drive would look but took the chance and I am so pleased with the result. I would strongly recommend the coloured sealer it's saved me a new drive and looks just as good if not better than the original drive when new.

Categories: Block Paving Sealer
Product Description

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. PLEASE NOTE: old or poorly conditioned pavers may require two coats of Block Magic to achieve a uniform finish.


 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 (coverage may be reduced to around 2.5 m per litre on old pavers)
  • Other Colours Available

There are 2 methods which can be carried out on Block Paving. The first method is to keep the sand the original colour and the second to change the colour of the sand (whilst protecting the area).

Application Guidelines To KEEP Sand Original Colour:
  1. Ensure paving is pressure washed/cleaned to remove all surface debris and 'muck' from joints.
  2. Leave paving to dry for 5 clear & dry days.
  3. Apply one coat of Block Magic with Roller. If you're changing the colour you may need to apply two coats (coverage in description)
  4. Leave Block Magic to dry for around 3 hours.
  5. Re-sand surface area, with "kiln-dried sand".
  6. Lastly, apply a coat of the Smartseal Block Paving Sealer MATT or SILK, this will adhere to the colour and solidify the sand.
Application Guidelines To CHANGE Sand Colour:
  1. Ensure paving is pressure washed/cleaned to remove all surface debris and 'muck' from joints.
  2. Leave paving to dry for 5 clear & dry days.
  3. Re-sand surface area, with ''kiln-dried sand''.
  4. Apply two coats of Block Magic with a Roller, leaving 2 hours between each coat.
  5. Ensure no rainfall is due for at least 8 hours after application.

After correctly applying the sealer, expect to have between 3-5 years protection*. Sealer longevity will vary dependent on a number of factors such as: traffic (foot/vehicle), weather and general maintenance.

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 (around 2.5m per litre on old pavers). 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 23C 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:

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.

Product FAQs

Q: I have just used the block paving sealer grey how do you clean the paint tray and brush as water doesn't do it

John hicks

A: We do stock a tool cleaning fluid. Our recommendation is just leave all items to dry and store away. Next time you want to use, just soak in the sealer for 5 mins and you can use again.

Response from Nigel

Q: Is it possible to ship products to Kenya in Africa


A: Although it is possible, the shipping costs can be very high, especially for small quantities of product. We would usually ship to a freight forwarder of your choice here in the UK so you take care of the shipping aspect and costs related to the order.
