Help!: What notch?

[Mozza]

Hey guys need your advice, i'm use 300x225's wall tiles with keraquick in a tanked shower room also 300x300's on a wooden floor (new build chipboards) again keraquick.. both ceramics..

I was going to use 8x8mm square notch for the walls and a U notch 10mmdeep x20mmwide would this be ok??

Thanks all.....

ps. should i be using Latex Plus?

sounds ok if walls are straight,i personally wouldn't use keraquick on the walls !!
to quick a set time,keraflex maxi better suited to the walls as its a slow set.

I use a 5mm for walls, dont think you can go wrong with an 8mm, your just using a bit more addy than you have to, 10mm is fine for the floors

trowel sizes seem fine Mozza, but would overboard your chipboard with hardiebacker 250 mate

[whitebeam]

Personally for floors I use 12mm, if there that bad then increase. Chipboard on the floor, what tiles are going down

keraquick does have a good pot life tho' Joe, about 3 hours I think

i normally use a mixture of notches on walls 6mm and 8mm just incase of imperfections.
the notchsize for the floor should be fine......but in my opinion tiling on to chipboard is not a good idea as there is far too much deflection in it and should be overboarded with hardibacker or marine ply.

Keraquick is great for walls....long bucket life and nice and creamy to use...

I used it last week in the heat and no probs going off too quick unlike the previous week when i was using *** rapidset f/white and it was flash setting in 10 mins in the bucket...had to switch to standard f/set..

Thanks all .. tha chip board is the treated 18mm stuff, the area is at most 1.5x1.5 if i board it what thickness should i use?

Would you use latex plus in the floor mix?

[Dave]

I would over board with hardi 6mm then use keraquick if the floor was solid..

[Mozza]

Hardiboard it is then, where can i get it from i live in the stockton area? Do you mean i should also use Keraquick to set the boards also?

Thanks again!
