10mm trowel on wall.

[FreeD]

I'm currently fixing 330x250 ceramic tiles to the wall with a 6mm wall trowell using weber fix plus (max bed 3mm) i'm finding that although i tried to get the wall as level as poss before starting that using these bigger tiles its much harder to get them all level. Can i not just use a 10mm trowell on the wall? I feel it would save me so much time twisting and pulling and pushing etc...if so can i use weber fix plus or can u recommend another tub adhesive that would be ok for this depth white star maybe? prefer not to use rapid set on this job it will just make it even slower!

thanks

Hi mate, switch to cement based instead of tub then 10mm trowel ok.
Would not recommend using 10mm with tub adhesive, likely not to dry properly. Dispersion adhesive !!

Use a cement based addy with a 10mm trowel. Just make sure you use standard set and not rapid set. I usually plum for Ardex X7G+ with a 5 hour bucket life which means I can make a decent amount and not have to worry about it going off. I certainly wouldn't use a tubbed addy.

Prime gypsum based walls with appropriate acrylic primer first

5 hour bucket life thats good...don't know if i can get ardex something ctd or topps would sell? any other cement based with long bucket life and high adhesion?

[Dave]

I agree ......use a standard set cement addy...plenty working time then..

mapei p9 is good......8hr bucket like..

You should be able to get Mapei from CTD.

Good high grab as well !!

[Dave]

I use p9 for most wall tiling now...

some times rapid set if in a hurry...lol lol..

[Aztectiler]

Prime all area and use standard cement based addy not rapid set. Mapie or Ardex for me.

[FreeD]

whats the differencve between p9 and keraflex? both look the same or flex is flexible!? p9 available in white? Dave do u always use 10mm trowell on walls i see no point in using a 6mm if using cement based?

Interior and exterior bonding of ceramic tiles and mosaics of every type on floors, walls and ceilings on conventional substrates (cement renders and screeds, underfloor heating installations, brick walls, blocks walls, gypsum boards).
Also suitable for tile on tile with medium-size tiles (up to 900 cm2) and spot-bonding of insulating materials such as expanded polystyrene, expanded polyurethane, rock and glass wool, Eraclit® (wood-cement panels), sound-deadening panels, etc.
Installation over gypsum based or anhydrite based surfaces is possible after having first applied Primer G, Mapeprim SP or Primer S. Coverage
2-5 kg/m2. Packaging
20 kg bags, 4x5 kg boxes.

Keraflex
Cement based adhesive with fair deformability, good adhesion strength and no vertical slip, ideal for ceramic tiles and stone materials.

Interior and exterior bonding of ceramic tiles, stone material and mosaics of every type on floors, walls and ceilings on conventional substrates (cement renders and screeds, underfloor heating installations, brick walls, blocks walls, gypsum boards, concrete with more than 4 months curing time). Keraflex ensures perfect bonding to all normal material used in construction and is able to absorb substrate deformation.
Also suitable for tile on tile with medium-size tiles (up to 900 cm2) and spot-bonding of insulating materials.

I've used tubbed addy for those size tiles before now, and appear to have got away with it. BS recommends the max area is 12x12.

Having said that with so much expertees pointing towards cement based addy, I don't think I'll do that again. Although both Topps and CTD would recommend Tubbed addy.

One tile shop which I will not name sold cheap brand tub adhesive to a friend of mine who was tiling his bathroom in 600 x 400 travertine !!! They knew what he was tiling !!!
Just because they work at a tile shop does not mean that they always give the correct advice !

[cornish_crofter]

But both shops and all staff within them, now that's a PROMLEM!

rapid set is fine to use on walls but the pot life isnt very good probably best of using spf

I'll be using Keraflex soon on a conservatory floor.
Has a pot life of 8 hours and also an adhesive thickness of 3-15mm which may help FreeD with any rough walls.
Out of curiosity i have a 15mm depth trowel can this be used on a wall or is it's purpose be for a floor

[Leatherface]

Dread to think the state of the walls if a 15mm trowel is necessary !!

you will find that it will need to be keraflex maxi to get 15mm bed depth...

I know I'm on another planet but do any of you guys add cement to your adhesive to prevent slippage.
