Slurry pointing

[Pablo]

hi fellas I've a quick question about something that's been on my mind for a while. Has anyone one on here ever experimented with or got experience of adding the likes of accelerators and frost proofers etc in slurry mortar. Also has anyone ever tried rapid set cement the reason I ask is that we do a lot of it and I'm looking for ways of speeding things up in the winter months due to the climate. Pointing both flags and setts any thoughts appreciated even if you think it's a stupid idea. Cheers

I never liked slurry jointing in winter. It never dries properly (although it does cure, which is a different thing) and so it was always a bloody nightmare to get the surface properly clean and free of any stain.

Accelerators and frost-proofers just exacerbate the problem at this time of year, so again, they were avoided if at all possible.

there is a thread on another forum regarding slurry pointing and the guys doing the work are Swiss

to quote:-
After all paving had been installed, dressed and cleaned; they sprayed down the paving and simply emptied wheel barrows of very wet mortar onto the paving.

They then used hoses and massive sheets of sponge and whilst walking backwards and dragging these large sponges left the paving looking spot on. No mess, perfect pointing, smooth and flawless.

Every now and again they would carry the mattress like sponges to one side and clean them down with fresh water then continue dragging... the pointing looked perfect. No stains on the paving either

--------------------------

now that's not much different to the way cookie explained it to me other than he uses a carpet and then jet washes the following day with water and acid

this seems to be a cleaner way using the sponge and more like you would finish a tile floor if you had grouted the joints and when you have cleaned up the pointing is finished so you don't need to return the following day to clean the surface from any staining

thanks for the replies. Cookie I've used ready use slurry whenever it's specified but just can't afford it when I'm quoting against others on standard work. I've never found that staining or residue is a problem for me. I pointed some sawn sandstone yesterday with slurry and it's turned out very well but I had it covered by 9.30 and had to wait till 3 before it was ready for cleaning. Just looking for a faster finish but I'll just keep on keeping on.
