Hi – firstly, I must say that I have lost count of the times I have referred to Paving Expert – the information is second to none.
I am having about 200m2 of fossil mint sandstone laid (some sawn – some riven in different areas). I have trawled this forum (and others) to research jointing compounds (Easyjoint, GftK, Marshalls Weatherpoint 365, etc.) and it seems that there is no consensus on the best product.
I had settled on Easyjoint and based upon 30 tubs had been quoted a good deal of £28 / 12.5KG tub. However, I discovered today that my builder has bedded the paving on approx. 5:1 mortar (full bed – not dot-n-dab). Easyjoint’s advice is that the “Dry Application� method should be used where the mortar bed is stronger than 7:1 and that this method should be “used with caution and wherever possible avoided�!
Easyjoint stipulate a 7:1 or weaker mix to allow water to drain through the mortar and, presumably, to allow the jointing compound to cure and to prevent standing water below the joint. My question is: what would be the best alternative jointing compound which would be compatible with a hard 5:1 mortar bed?
Many thanks in anticipation.
