Hi everyone, I have a block paved driveway charcoal and brindle in colour which was laid roughly 3 years ago.Last year i got a resin coating put on which looked fantstic for the first few months.Then it started to turn light grey in patches(not eff) then after a few more months the whole drive was coverd in this light grey coating to the point where you cant see the colour of the paving.Its as if the resin has had a reaction with the block paving?the resin does crumble away but only in small areas.I have tried jet washers/scrubbing but cant remove the resin even contractors dont want to know(not enough profit for the effort to take it off maybe) ive heard only bad things about brick acid but it might be my last resort.Is there anyone out there who can help, any input would be much appreciated.

Truth is i dont know it was done by The Driveway Doctor franchise group (a right bunch of cowboys) they were very vague not even giving us a technical spec only saying its a resin.

Oh dear! Another clown that has sent the very same question in by email, thereby doubling the amount of work I have to plough through, despite it stating quite explicitly in the T&C's not to do so.

Only just seen this post, sounds like you have been ripped off, have heard about this franchise, won't say anymore.
Anyway do you know what the resin is, acrylic or poly?
Brick acid won't get this off so don't even go there.

I think it was poly?(Wet Look) sorry to be so vague.

That don't help sorry, as acrylic can have the "gloss wet look" also.
Give me a day or so, I'll try to find out what they use as a sealer and we can see what will remove it, will put my Sherlock Holmes hat on.

i am very wary of anyone not qualified calling themselves "summat doctor"
i had a clown round to fix my tv called "tv doctor" he took the back off and left allsorts all over the living room before leaving with a cheque muttering about "must order parts bla bla bla"
the next time i saw him he was delivering milk,so i collared him.

Had a look at their web-site, betacoat is what they say they use, it's a "Specialist Pre-Polymer Urethanes" so a polyurethane. It is going to be a pain to remove, but not impossible. I understand you have spoken to Tensid, and Richard gave you some advice, I too would have recomended eZee strip for this if you are going to do this yourself. It will be a messy job though. Tried a search for betacoat.com and it don't seem to exsist? so that's a worry. Are "Drive Doctor" still going? I thought they had gone out of business. Let me know if I can be of anymore help.

Yes but not house-hold bleach, what you need is Sodium Hypochlorite aka chlorine bleach, try to get 12-14% it's what is used in swimming pools. If you can get hold of some let me know and I'll tell you how to "mix it". You do have to be careful as this stuff does burn the skin etc.

Yes, but will a bit more expensive from those places, I get my from a chemical supply I pay around £7.50 for 10 lts. You are not to far from me, let me know how big the area is etc, and I'll price it for me to do it for you if you want, saves you the hassle?

Roger: why not household bleach for algae? It's always worked for me, with no visible problems or undesirable aftereffects
