I dont know the difference between sandstone and limestone,
but lets say its kota black limestone
laid on 6in of crush'n'run compacted
1in of merseygrit sand very blinding layer
stones set on a full bed of 4:1 merseygrit and cement
the backs of the stones were pva'd
joints of 7mm
I want to use gftk's vdw840 polymeric sand to point the joints.
I want to seal the patio for that rained on look and to protect from stains.
I phoned NCC who supply the vdw840 and asked should I seal first then point and he said he would do it that way round
question - would you seal now (few days after laying) or wait for potential efflorescence to show? the family are desperate to use the patio.
and would you use lithofin stainstop outside? or another product
and would the lithofin effect the polymeric sand
and where in the mersey region would you get the lithofin or just ebay it
any input grately appreciated
ps the polymeric sand; is it water proof, does it matter with a full motar bed below?
