There are cloudy, white areas on my Paving – what can I do?

Posted in Block Paving, External Sealants, Paving   

If there is any moisture left in the paving [or the sand joints on block paving], this moisture will cause a clouding or whitening of the surface. This is not a problem and is really easy to remove. The whiteness or clouding is caused by escaping moisture forming microscopic carbon dioxide bubbles which are trapped within the thickness of the resin coating as it is curing. To remove the whiteness or clouding, simply spray a light coating of AdSeal solvent over the affected areas. This will allow the surface of the resin to soften which will, in turn, allow the carbon dioxide bubbles to escape. The sealer will then re-solidify without any adverse effect. If the clouding/whitening returns simply repeat the process.
