  • Smartseal Paving Sealant Before Application

Smartseal Application and Directions for Use:

On new blocks, you should apply this sealant as soon as possible after installation and sweep away any excess sand that may be leftover. 2 coats are needed but please make sure to leave 2 hours between coat applications. The temperature outdoors should be over 12 degrees Celsius when applying and the surface needs to be completely dry. Do not apply if rain is forecasted within 12 hours and do not apply if the surfaces are damp or wet.

On older blocks that are have been laid for some time, you will need to thoroughly clean first with a jet pressure washer and allow it to dry out completely for a minimum of 5 days before application of joints repairs and sealants. The solution can be applied with a specific nozzle sprayer but a brush or a roller works better in our opinion and the volume available goes further when just using a brush (but tends to be more difficult from a labour point of view). When applying 2 coats, you should plan for 2 meters squared per litre for the first coat and then 3.5 meters squared per litre on the second coat.

Part 3: Conclusion

As there are so many different types of block and patio paving out there be it concrete, natural stones or slabs, we would advise testing it out on a small patch before you commit to applying the full application to the entire area as it could be a very expensive mistake. Perhaps get 2 or 3 different variants or samples and test these out in small hidden areas so the entire area won’t be spoilt as there are no guarantees that you will like the final appearance. Some can change the colour slightly making them darker, some can give a wet slightly unnatural look and some will give a nice matt type wet sheen finish but again you are better off testing them first on one or 2 slabs first before you make your final commitment and leave it sit for a few days to see how it goes.

Which one would we choose? Our preference is the Smartseal 25 litre drum sealer which can cover 50 meters squared and works out at around £5 per litre which is fairly good value for what you get to be fair. Secondly then we would recommend the Adseal 25 litre drum as that generally works out at less than £4.50 per litre which again is good value and the finish is quite good and reliable. If you want the cheapest possible solution though, then choose the Rycal 20 litre drum as that one is available for less than £3.50 per litre when seen at the time of this review.
