Hey guys

My dads just had his drive in a light grey. Now he's sealed it and it ranges shortly after now it's turned patchy. Can anything be done about it?

Bit more info needed, what products were used on what paving. Do you mean it rained shortly sealing?

Thanks for the reply. It was Polyurathane made by paintmaster 2000 and yes it rained around an hour after the sealant was applied

Just had a look at their site, which one have you used? as there are a couple of choices

I'm not 100% sure because it's my dads but I would of thought it would be this

Paintmaster Clear Floor Sealer 20L

Had a look at the MSDS sheet that this lot have on line, not much use at all, this is a polyurethane sealer so can be a pain to remove, but the MSDS sheets "recommends" thinners so might be worth try a bit on the effected paving to see if it will "liven" up the sealer if it does then this would allow the moisture to escape, allow to dry the just reseal the ones you have worked on, if this makes sense?
From the photo it doesn't look to bad a job, shame it rained (the joys of sealing) I'd try this if it does not work then usually I'd say you have to remove the whole lot and start again, messy and expensive, sorry.

thanks mate will tell him to give it A try. Can you recommend a sealer? he was on about getting them all taken up and replaced with brindle coloured blocks but it will be around 900 pound to do which is not good to say he only got it laid last week

For me Resiblock is about the best for block paving, they do a couple of different products, so depends on what sort of finish you want?
