Application Guidelines:
- Ensure paving is pressure washed to remove all surface debris and 'muck' from joints.
- 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: Can this be used to seal a small concrete path? Thanks
A: We would recommend our solvent based external concrete sealer for sealing a concrete path (sample available)
Q: Sorry if it has been asked but can you use this on natural stone and sand stone patios. I am going to buy this for the front drive but if it will work on the patio too that is a bonus thank you
A: You cannot use the polyurethane block paving sealer on natural stone driveways or patios. This is not a breathable sealer and could cause problems if applied to natural stone substrates.
Q: Is it ok to walk over the first coat if not quite dry to apply the 2nd coat? I will wait the recommended 2-3 hrs (max 4hrs) before applying the 2nd coat.
A: After applying the 1st coat, the surface needs to be at least touch dry before applying the second coat of block paving sealer. Hope that helps.

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.
The sealant brought my block paving patio back to life enriching the colour and definition.
