Hi,
I have cast stone paving at my front door (from Haddonstone many years ago) which has gone black. I will be getting it cleaned with a DOFF system, but wanted some advice about what I should seal it with afterwards? As it is a few years old it is quite porous, and I want to stop it going black again so quickly!
As you can see from the photo, I also need to repoint the slabs. Whilst Haddonstone etc sell a pointing mix consisting of crushed stone that is mixed with white cement, I don't find that this lasts very well. Please could I get some advice on other options?
Many thanks in advance,
Lesley
