- Leave paving to dry for 3-4 clear & dry days.
- Once dry, before sealing. Push Kiln Dried Sand in between all joints on Paving.
- Apply 2 coats of Block Paving Sealer with either Roller or Sprayer (Apply two coats of sealer - applying the second coat within four hours of the first to ensure the coats 'key' together correctly.)
- Allow 24 hours for sealer to completely cure.
After correctly applying the sealer, expect to have between 7-10 years protection*. Sealer longevity will vary dependent on a number of factors such as: traffic (foot/vehicle), weather and general maintenance.
Urethane based block paving sealer is only to be used on precast concrete block pavers (traditional "block paving") and cannot be used on any other form of paver, brick, patio slab, natural stone or block pavers if they are finished with a top course of natural aggregate.
*NOT TO BE USED ON CLAY PAVERS*
*** 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
- Only apply sealer when the block paving is clean with jointing sand and paver totally dry with no rain forecast for at least 8 hours.
- Temperatures need to be above 10 degrees centigrade and below 23 degrees.
- Only apply if no efflorescence (surface salts) is visible
- Make sure pavers are thoroughly swept and that no jointing sand remains on the surface or high in the chamfers of the blocks. This could lead to unsightly sand becoming sealed onto the surface of the blocks
- Apply to borders with a paint brush or small roller.
- Application to main areas by roller or squeegee at ratios of 2sq metres per litre 1st coat and 3.5 sq metres per litre 2nd coat
Leave between 2-3 hours and no more than 4 hours between coats - Avoid vehicular traffic for 24 hours and try to avoid walking on for around 3 hours after second coat
- Always wear a protective mask, goggles and gloves all all times

Q: I may be getting new block paving for the front of my house. How long after laying the the new block paving should the polyurethane sealer be applied? Also, can the weed suppressing Polymeric Sand be used or must it only be Kiln Dried Sand? Thank You
A: Although some people seal the block paving We would normally recommend waiting around 6-8 weeks to ensure any efflorescence comes out prior to sealing. You could use weed suppressing Polymeric Sand if you wanted to, but the sealer will harden the sand anyway.
Q: Hello, what is the difference between "Block Paving Sealer MATT" and "Block Paving Sealer Polyurethane" ? Thank you!
A: The block paving sealer is a solvent based acrylic sealer used mainly for domestic purposes. The Block Paving Sealer Polyurethane is a commercial grade sealer that is mainly used for large commercial projects due to its durabilty and resistance to oil splillages.
Q: Can you apply this on a slurry grout (such as Flowpoint)? You mention its great for kiln dry sand that's between the pavers. But what if there is a different type of grout between the pavers?
A: The Block Paving Sealer Polyurethane has only been tested and formulated for use with kiln dried sand. That it not to say it would not work in the situation you have described, but it would be best to test with a sample first to determine suitabillity.

Sealant was delivered in three days and applied after cleaning the block paving and a lengthy dry spell. I applied one generous coating using a 6" brush and it dried quickly in the warm weather before the recent heavy rain. The blocks look good and the rain runs off the surface of the blocks. One piece of advice is that the product should be used in one go. I had some left over at the bottom of the container and it turned into a runny jelly substance overnight. I recommend the product and would use again in the future.
The block paving sealer was delivered on time and product is as described. Easy to apply with a small roller and has left the block paving a little darker with a slight sheen. Water can be seen puddling on rather than soaking in to the blocks so has definitely sealed them.
The block paving sealer went on well and Im happy with the finished results. Unfortunately delivery let them down badly. 2-3 days turned out to be 7 days and lots of palaver inbetween.
