In  my limited knowledge on this subject I'm under the impression the sealers used on block paving are pretty much like the ones we have for hard floors - either surface sealers or impregnators.

I have seen some AWFUL sealing jobs on drives which look like surface sealers have been applied too thick.  They are really slippery when wet, and also have gone white and hazy.

I have read on a few websites about other sealers which I think are impregnators - I'm guessing this would be more appropriate.

My parents are having a new block paved driveway laid soon and I'd like to seal it, providing it's the best thing to do.

Anyone have any useful info to share on the subject?

Cheers

(sorry to some people if they've read this in 3 different places!)

you can get none slip sealers jim and if driveways that have been sealed have got white patches, its becauase theyve sealed it while the driveway was still a bit damp, either from the clean or from the weather, always seal when the drive is bone dry, use your damp meter

if you do get white patches these can be rectified with xylene.

hope this helps.

Cheers.  Yeah putting sealers on when the material is not dry, have had a bad experience with that

I'd already found that smartseal website and also Resiblock but JEEEZUS that stuff is expensive!  THis is what I'm trying to determine, I'm sure all these block paving sealers are the same, they are acrylic cross-linked polymer wotsits, exactly the same as the topical sealers we use on hard floors.  But I suppose they are different grades, solids contents or something.

There must be some reason for the huge difference in prices between some of them.

I have ordered 2 free samples from Resiblock.  I've got some spare block paving bricks, already treated some with a topical floor sealer and some with HG impregnator.  I'll add the two Resiblock ones and then test them all out for water and oil repellancy.

Will post up findings!
