Having a nightmare with a 80m2 stone sett drive we finished last week . We originally pointed the joints with a semi-dry mortar mix dyed dark Grey, but some small areas of slight tonal difference caused the clients to change their mind, after we'd bloody
finished the whole area !! and asked us to clean it out and apply a slurry grout, Instarmac's, that I'd originally quoted for but the extra cost had put them off. They have offered to cover the difference and to pay for the extra labour, not the headache though, but on Saturday we did a small area, approx 9m2 which needed to be done because the client has cunningly booked his windows to be replaced today and the contractors can't call off. Alas with the mini hot spell we experienced on Sat afternoon part of the area, approx 1.5m2 went off before we had chance to clean it, pure inexperience really, but I need to get it off obviously or lift and replace. Anyone with any ideas???
i normaly make my own slurry and clean of with 32% hydercloric acid then a very good preasure washer not normal brick acid as its only up to 16% strong you need a chemical manufactorer

Cheers, managed to get it off with "Lithofin" cement residue cleaner and a large amount of elbow ...well not me , one of the lads, the rest looks pretty damned good, picked up 3 quotes off it already and that was whilst still cleaning it!!
The job must be paying well if you can afford the Lithofin Cement Cleaner jollop!
Cookie: get some of that high-strength juice you use, dilute it 50%, put it in a fancy bottle, call it "Cookie's No1 Cleaning Compound" and sell it for a tenner a litre - you'll never need to lay a sett again! :p
£15 a bottle mate and it worked a treat, like I said it needed a bit of a scrub as well. Job looking good and Grout will be something to use for future jobs, we'll just make sure we move a bit quicker next time
the brother got it neat from the roof tile place next to his work (10l to a 1000l of water as it stops new roofing tiles turning green), burnt through his shed floor. must admit it did get the stains off his patio.
