Friend showers being done

[btw574]

Took a picture of a shower beeing done at my friends house. He is having two done and they have already started tiling one of them and it is the same. None of the joints between the backer board were thinset and neither were the corners. They put mesh tape on the joints and then redgard. Most of the corners look like this and this on you can see the framing because the gap is about 3/8". I told him to have them stop as all the joints should have been filled
with thinset and mesh tape and that he will end up with a leak. This is a large bath and kitchen place doing the remodel.
He did not believe me but if I can get some advice to show him before they finish.

Brian,

You can get the information straight from the manufacturers web site

I don't see an awful lot of screws on those boards either. Check the specs for the spacing on those as well so he can present it to the installers. Might be best for him to just skip straight to the owners if it's a larger company though.

they also specify which fasteners can be used. (NO drywall screws)

Besides not reading simple installation instructions, they need to put on a few more coats of RedGuard. Not even close to enough. Shouldn't be able to read the printing on the board.

YEah, I was going to say, that didn't look like enough RedGard on the walls. To be certain, you need to use a wet film gauge to verify the proper thickness of each coat (and it requires more than one!). It is crucial to get the proper thickness and to prepare the subsurface properly.

Lots of things wrong there...good catch. It's really sorry that supposed pros can't or won't follow manufacturer's instructions or think they know better than the people that make the stuff and provide a warranty.

The TCNA says 75% of the tiled showers built in the USA do not meet standards, and it's people like this that keep that average so high. Done right, one can work reliably for as long as you care to keep it around because of the style.
