hi Dave, managed to use the grimex today on the top patio where the acid was, no change there,but we thought there wouldnt be anyway as the patio cleaner with the acid has probably removed the sealant,(the only problem here is the lack of colour, the greyish white) so now we need to do the next process with the stone oil. The bottom area of the patio where the marks were, have lifted and we can see a result, but not sure if the one coat of thompsons sealant has been fully removed, so would it be worthwhile cleaning bottom patio again? Or do we put the stone oil on these followed by the colour intesifier or because these havent been touched with the original patio cleaner and still remain dark do we just apply the colour intensifier?

Yes, you do need to make sure you have removed the thompsons sealer fully.. even if it means a mild solution of what you used before.. once cleaned the stone oil will work.. followed by the colour enhancer to give a lasting seal.

thanks Dave, the top patio, where the patio/acid cleaner was applied, I dont think that will come up anymore, and we have applied the Grimex to this area also, I guess the acid would have removed all the sealant of that, as its definately took the colour, so when its dry and we get some nice weather (as I think its heavy rain all week) and it has dried out, should I just brush it down and proceed with the stone oil? I think we are going to concetrate on the top patio first and get that right! Thanks for your sound advice, Lucy

As long as it is dry then ye.. sounds good to me.

Hi Dave, have applied the stone oil yesterday and already its looking great! Not sure whether to apply another coat or just go on to use the colour intensifier as I am quite happy with the colour that they have come out and dont really want them any darker! So is it ok to apply just one coat of the oil? I have noticed tonight that the flags feel quite sticky so not sure what to do about that, any suggestions? I am hoping to get some good weather so i can do the colout intensifier, if this doesnt get done in the next couple of days, could the rain harm the stone oil on the flags?
