never heard of the method before but i think i will now adopt it sounds good to meI'm sure this was one of Grumpy's tips......
Place a full glass of water in the middle of the floor. Walk and "bounce" on the floor, if the water spills you must strengthen (or at least eliminate the deflection). If the water remains in the glass, then either use Ardex 7001, Mapei Keraquick with Latex Plus or BAL Fastflex to tile with. Check the packs for details regarding priming.
Sorry Russ, just repeated what you've already said :smilewinkgrin:.
