Slurry grouting

[eddy600]

i have a customer who wants their driveway pointing, so i have cleaned them up and blasted out all the dirt from in between and i am left with how it is in the photos, would these setts be suitable for a slurry grout or are the joints not deep enough?

Was thinking a 4/1 sharp sand cement and sbr and plenty of sweeping budget dictates this method over pricier resins.

the 2 part resins will last a whole lot longer than 10-15mm of slurry,
I hear you on budget of course
be a lot of cleaning using sand and cement

Not my budget so working on a day rate for the pointing, how long should this take 2 guys to slurry point?

Cookie or Dempsey would tell you better than me,as never done slurry
you will get it in there quick enough,its keeping it cean that will be the heart ache
think cookie uses a belt cleaner, dempsey a lazy boy

how many metres you got?

Theres about 70sqm total will be brushing like crazy and have a industrial pressure washer to aid clean up if need be, just hoping it can be done in a day between two of us.

I have only ever done epoxy grouting but I reckon a day is a bit ambitious for 70 m2
allow more and gives you a comfort zone if it doesnt go to plan

Managed it now but has dried the stones a little hazy which I thought it would, next question is what percent hydrochloric acid and diluted to what ratio should I use to remove the haze thank you all photos to follow.

[lutonlagerlout]

main thing is you need to pre wet the stone before using hydrochloric, i would use strong stuff
obviously full PPE that stuff is nasty

Sorry didn't see this post I've never used acid to date we always clean off as much as possible with squeegee then everything with buckets and sponge.
