Block paving sealant

[Andrew Westwood]

Can anyone help?

We have had block paving sealed, the person who done it was useless and now have white marks because it had rained morning he did it.

Can we get advice on its removal, as he can't seem to do it.

Thanks

Hi Andrew,

I'm also looking to find out how to strip a sealer. Had a patio done and the sealer was put on too early and now has gone from black to grey because of trapped water.

From my understanding it's a case of putting a chemical on and letting it break the sealer down a bit, then jetting it all off.

Just need to know what chemical to use.

Anyone?
