Tile Spacers and Grout lines

[grumpygrouter]

It is interesting this Hardie stuff. The 6mm hardie ia a denser product than the 10mm according to Hardie spec sheets and was designed specifically for floors. Whether it adds strength or not has been questioned before and as yet Hardie has not provided any definitive answer.

It would be good to get this clarified if possible.......Holahana?????

Personally i wouldnt use a backer board for strength anyway.

Other parts of the world, such as downunder, don't consider either 6 or 10mm cementboard (hardi etc) to add any significant strength to a floor. It's merely deemed a more stable substrate for tile than plywood. I think if you approach it with that attitude - get the subfloor up to minimum deflection standards (l/360 over there?) you'll be right.

Over here, the benchmark for floor strength is 22mm chipboard on joists with 30cm spacing. Anything weaker than that has to be reinforced before recieving tiles, and that's either done with a minimum of 12mm SLC reinforced with 2.5mm rebar netting, or through gluing 12mm fibercementboards or floor grade plasterboards (alot denser, heavier, and more rigid than regular ones) with cement based adhesive, specifically C2F/S1-S2 type adhesive.

Epoxy grout is waterproof, but if you have a leak, you need to be very sure it is just the grout joints causing the problem. If your grout has cracked and leaking why has it cracked? Just replacing the current grout with epoxy stuff may not actually solve the problem.

Hi TQ, I am afraid I really don't know what to suggest about finding epoxy grout. Maybe if you check out [DLMURL="http://www.ardex.com"]Ardex Global Loading...[/DLMURL] you may find somewhere in your country that supplies it. They make an epoxy grout but I have never used it.
