Q: It wasn't supposed to rain but 2 hours after applying the second coat of the solvent free, eco sealant it poured down. Will this have ruined all of our hard work?
A: It might be OK, but the issue you may have is some surface whiteness if the sealer hasnt fully cured when the rain came. Best leave it for a few days to see if any surface whiteness appears. Please call our office if any issues as described above occur.
Q: I’ve sealed my block paved drive with the smart seal solvent based. Could I re-coat with solvent free on top of the solvent based later on in the year.
A: You should not put the solvent free block paving sealer over the solvent based block paving sealer you have already applied as they will not key together. If you want to put more sealer on you should use the solvent based block paving sealer.
Q: Can I seal my concrete block paving although a few look abit damp around the edge. Thank you
A: It is always best to avoid sealing when moisture is present. If moisture is present when you seal the block paving, it could result in surface whiteness (blooming) in areas.
Product not used yet. Delivered on time and well packaged. Excellent communication from Smartseal.
Good block paving sealer, easy to apply and went further than i hoped.
Easy to use sealer with no smell. Used on new pavioursand the slight colour change was an improvement. Job not yet finished on quite a large area and I'm not sure if I have ordered quite enough.
