I was just looking for a bit of info regarding pointing with a cement slurry. We have just laid a 60m2 drive in sawn granite setts with a flame top 400x100x100mm. I have used 'Instamac Flowpoint' before now but not 100% happy with it.
Back to the slurry....What mix is best ? 3-1 with a washed sand ? SBR and plastisicer in mix ? I know it requires a lot of squeeging, cleaning, light hoseing, belt cleaner ?
Any tips greatly appreciated ! Thank you

Hello Mick, the last one we did (150m2 on 3x2 standard flags) has crumbled in many places, it was a rake out and re-point job on an existing drive (not one we had laid) so maybe the joints just weren't clean enough, whizzed out the old gear/soil about 50mm, or there was slight movement in the flags, it has knocked my confidence in the product now. Also it would cost an arm and a leg to point this area as the setts are 100mm deep so was looking to try a cement slurry at a fraction of the cost as long as it was up to the job. Just sruggeling to source a belt cleaner at the mo !

Got ya mate, how about brushing and compacting in some semi dry concrete, with 10mm aggregate, and leave yourself 25 mm to point, let that go off and either Flow-point or Slurry, personally I'd flowpoint, but I understand if you've had issues. Go with Cookie, he's very old so he knows lots of tricks.

'Amost Yoda like'.....Brilliant !
Yeah I have done what you suggested on another job, the only problem is, it's about a 6mm joint on these setts so would just have to use a washed sand, no stone, but the only problems with doing it that way is that its very hard to get it an even (ish) depth of fill in the joints, i.e none in some areas and filled to the top in others. Also I'd be concerned that washing it into the joints with copious amounts of water would seperate the sand from the cement, or would this not matter if it was topped with the Flowpoint ? What is the minimium depth for Flowpoint ? 25mm ? Thanks

Hi matty you would be better using 2 part epoxy on that job give Gtfk a call size of units sq m and they should give you a good rate mention me and Tony mc done in one day and no cleaning slurry is two days extra work with the cleaning element if your busy it's a no brainer ps must be the two part and mix in small mixer for good results ring me for more info cheers cookie ps should be doing a job in Liverpool shortly

Thanks Cookie, sorry just seen your latest reply now. I used the flowpoint after half ish filling the joints with a cement slurry (A few days before) and hosing the tops off. Worked ok but set me back £320 plus vat for the flowpoint. Ive never used that Gtfk before, heard of it but thats about it. Where in Liverpool will you be working ?
