I have done a few tiling jobs for myself over the past few years and would rate myself as reasonably competent!
I like to ask questions before going in head-first so as to limit any avoidable mistakes.
So, first question for you hepful chaps is..... I am laying UFH in my flat (kitchen & bathroom) which is constructed with block and beam floor with 100mm polystyrene insulation and 22mm chipboard floor. I am using 6mm insulation panels which I believe need to be stuck to the chipboard floor with Rapid Set Flexible Adhesive.
Now, do I have to first prime the chipboard floor with acrylic primer before sticking the boards down and do I have to prime the top of the insulation board before applying the Adhesive for the tiles?
Finally, The UFH mat is 3mm thick, can I lay the mat within the wet Adhesive and lay the tiles directly on this or do I have to lay the mat on a thin bed of adhesive first and let this go off before the tile adhesive bed and tile!?
Hope I am making myself legible!?
