   need clarrification, the main field of pavers are on sand over the conc patio, and the border is over ???

   use plastic curb if over earth, treat the same as field if on concrete ....

   Thanks,
   20'x20' slab. Thin paver covering all. Border on the slab, all four sides. Needs to be fixed some way so it won't move off the edge of the slab. Field pavers, thin also, on 1/2" screeded sand. I had my pool deck done a few years back and the border was fixed in place. Just don't know what they used.

   Any paver supplier will have paver adhesive- basically PLPremium type stuff, formulated for masonry situations. Works like a charm. Get the qt tubes. I did an overlay on a heated 'crete sidewalk, and filled the joints with polymeric sand. Run a double bead and set the pavers in place. Plenty of open time to shift things around. Smear some of it on your hands and you won't need gloves. For a week.

   Thanks,
   The only issue I see with that is can it bring the paver up to the same level as the pavers on the 1/2 bed of sand?

   Then use mortar.  And the white ceement adhesive painted on the slab where the border brick goes.

   The good landscape yards have an edging that anchors these border bricks in place.  Several different variaties, depending on the shop you go to.   If'n the slab extends out beyond the border, this edging tapconned to the slab may make the job easier.

   No, but maybe you can use regular bricks, or another type of thicker paver that will make up the difference?

   Or, as peteshlager sez, use the adhesive and mortar. Looks like Elmers, paint it on and let it dry, then mortar. That stuff works great.

   I guess my question now will be 'why do you need 1/2" sand bed? You can glue the whole thing down, or just set it on the concrete with a fine dusting of sand to absorb any discrepancies in the paver, or just brush in the poly sand and that'll lock everything in tight.Steve

   Thanks,
   I actually was going to try get away with 1/4" of sand, just to even out the lumps n bumps. I just thought I had to use 1/2 "

   If you use sand as a bed over a concrete patio what's to keep it from washing out in heavy rains? I can see using sand as a filler like grout. But when you get a deluge and the water cannot seep into the absorbent ground, it will wash out your "bedding" sand.

   Don't know why, but it doesn't wash away, and here in FL it can piss down hard. I had my pool deck done this way about 5 yrs ago and it's as solid as day 1, there's plenty of water sloshing around that thing. I'll have to get Ripley's to do a feature on it. I think the border will hold it in.

   you need to etch the concrete with a diluted mariatic solution before type S or paver adhesive

   if you have nasty swales that you need to even out do it with thinset mortar

   I'd set teh whole thing with thinset.

   Is that regular modified thinset? What size trowel do you use?Steve

   danusan10 | Mar 10, 2009 04:47pm | #15

   Yes use a high quality modified thinset. Notch size depends on slab.  If slab is fairly consistent 3/8" would probably be fine 1/2" if  it has alot of inconsistencies
