hey there, ive been doing a lot of ceramic floors but this is my 1st shower - bathroom project. Doing a full wall of ceramic with buckets of Omnigrip wall tile adhesive from home depot. I seem to be getting a problem to spread that thing could it juts be too thick ? Im using it on Ditra mat ( shower ) and green Plasterboard with a 3\8 square trowel. it doesnt spread well and seems to roll of the wall at some place its really long to get those line of adhesive there.
( Tiles are 8inches by 20inches )
its bare plasterboard and ditra mat ( over denshield ) even tryed on a primed wall and its not working well anywhere could it just be the product ? or am i missing a step. Or does it just sticks so much on the trowel that it gets it back from the wall ?

Thx for the help!

Abandon the dispersion adhesive and buy a cement based addy. Always stick my membranes on with rapid flexi and a 4mm trowel

hello,tubbed adhesive would not be my choice for any membrane or large tile,as faithy says buy a bagged cement based addy

Hello..

Terminology here might just help..

The mastic adhesive you have is no good to use over the Ditra.

You will need an unmodified thinset and it is your choice as whether to use a fast set or standard set thinset..

What adhesive do you use to apply the Ditra.?

Saw the imperial measurements and realised your on the other side of the water

i applyed ditra over denshield using unmodified bagged thinset ( white )

i though i needed modified thinset over it because i was using porcelain tiles and it would not hold to unmodified ?

thx

We in the UK do use a modified thinset but Schluter .com say not to in the USA/Canada..

Something to do with setting times, personally i would use a modified thinset.

alright thx dave so much poducts its hard to know it all being a carpenter

Despite the trouble of putting the adhesive on the wall its holding pretty strong when im pulling on it. All grouted today and the shower will be ready soon

The base of the shower got an 1 inches lip, tiles overlap 1\2 inches over it do i still need to silicone it to the shower from under ? or is it fine without silicone ?

It would be best to silicone it..
