Oh no not another re-pointing question - Re-point old 2x2 slabs x 200

[menoken]

Looking for some advice after reading re-jointing info, have roughly 200 old 2x2 slabs to do. At the moment i am in the process of cleaning out the joints, won't manage to do this all at once, so is it ok to clean them out, then finally wash down them all with hose before re-jointing.

Understand about the preparation being very important, re-bedding a couple of slabs that are loose. Been asking friends and so called experts advice and i have had about a half dozen or so different answers so ended up here.

Now when i go to my local buildbase or diy store what do i ask for, i am leaning towards epoxy resin mortar, but i am not a professional.

Any help would be much appreciated.

looking at those pictures a whole lot need relaying
for that type of slab and layout be careful as they are probably just laid on sharp sand,they may move if you remove the pointing
personally with such big joints I would use 3 :1 plastering sand : cement and point them with a pointing trowel slow but cheap on material
if you use weatherpoint365 its going to cost you a couple of hundred quid in gear at least

Thanks for your quick response, i tend to agree about them all kinda needing re-bedded, too big a job for me i'm afraid. Not keen on spending £100s on stuff that won't really work.

Can i purchase the plastering sand and cement pre-mixed 3:1?

Personly i would of cleaned them off first because you'll wash all the shite into the joints and, also you'll liquify ( is that actually a word? ) the bedding layer. A LLL suggests it is probably just sand and not a cbm. You could relay the lot bit by bit, won't take a kings ransom, or to long.

Thanks for the advice sean, so do you mean i could maybe work on re-laying maybe a dozen at a time, and what do i use for the bedding, cement based mortar (cbm)? Do i need any special tools?

[seanandruby]

Although ideally it is best to take up and lay in one go it is possible for a diyer to do it in stages at your own pace. They can be laid straight onto a grit sand bed, or a cbm ( cement bound material ) no "special tools" required, you could maybe pick up what you need cheaply at a car boot sale etc: Can't direct you to the main index on my phone but if you go to bedding layer, material and flag laying pages there is all the info' you need. Come back to us for guidance. Good luck.
