|Many thanks for your prompt response. I am thinking of using Resiblock Superior matt finish. I've read plenty of good reports about I and it does seem to be the best. I've also read the points about making sure all is clean first, so I plan dot pressure wash it after a few months to get rid of the efflorescence and then let it dry for at least 3 to 4 days providing the weather is good enough for that. I don't plan to do it until about June next year. Hopefully I can then time it so it has a couple of days to go off after application. Hope I've got all the bases covered but if there is anything else you can think of please let me know. Thanks again for your input. Cheers,|
Pressure washing alone won't get rid of the efflorescence but don't worry about that for now, as you are IMO doing the right thing, as in leaving the paving to go through a couple of seasons weather wise. So come next year, and lets say all you have is a dirty paving, bit green (algae) and maybe a few weeds starting to show themselves, what you need to do, is give the paving a good clean, use the cleaning mix that I have put up on the stain removal's page on the main site. After you have cleaned the paving, if you did have quite a bit of weed growth, pains taking as it is, apply a weed killer to all the joins/gaps, and leave it to dry out for around 3-4 days weather permitting. Then re-sand & seal in the same day (size dependent here) You need to make sure you have sanded properly so that no sand is sitting on the surface or proud of the joins use a soft bristled brush to re-sand, once you have done this (I now use a leaf blower to make sure the surface is clear of any sand) you can seal the paving, Superior Matt is a good choice.
