I am so happy to have found this forum!!:)
I have a few questions..
We are retiling our shower room and have removed the old ceramic tile on walls and floor. There is old ?mastic (yellow) left on the walls...
1. If I scrape it off I risk tearing off the top, paper layer of the drywall. Is this a problem in terms of how well the new adhesive will adhere to the wall? The current drywall is green which I assume is the type used for wet areas.
2. I went to a local building supply store and asked for waterproof adhesive. The employee told me that it's the GROUT that needs to be waterproof, not the adhesive. A retired contractor friend told me otherwise however I am unable to find a brand that states "waterproof".
3. If I install a mosaic tile on the wall, do I need to use a specific type of adhesive?
Thanks so much for your advice.

You can not use drywall (even the green stuff) in a wet area. For years it was done in some areas but has proven to be fatal. Now that you have damaged the paper the problems are even greater. The drywall should be removed and replaced with a tilebacker suitable for showers, there are many.:)

And you won't either. There basically is not such thing for use residentially, Epoxy grout comes the closet and there are others but even they wouldn't be waterproof under most conditions.
3. If I install a mosaic tile on the wall, do I need to use a specific type of adhesive?
Mosaics on THAT wall would be the end of the entire shower for sure.
Change the wallboard.
Waterproof the interior of the walls.
THEN, you can use any tile you wish.:)
The only problem now is the floor (receptor) also should be redone.

Here's an article about the use of greenboard in wet areas:

Thanks for your response. It was the one I was afraid of (changing the wallboard).
Today I was given another suggestion..take off the old adhesive, ripping the top layer if need be, spreading "mone grip" (?spelling), then putting a waterproof membrane on it, then spreading another layer of the mone grip and THEN tiling. Do you think that would work or is this shoddy advice?
I'm just trying to find another alternative to changing the wallboard as it would involve way more time/resources than I have. Not to mention the current wallboards were installed incorrectly (the longer wall extends behind the two shorter walls-it wasn't actually cut to meet the ends of the two shorter walls). Not to mention the fact that the vertical metal studs don't even have any horizontal support studs.
As my dad put it ... "this thing was built to never be tampered with!" He said if I take out the current wallboards I would need to remove and rebuild the entire frame of the shower room with wooden studs! He thinks I should just apply the adhesive over the old one and tile over...
I'm so confused!!!!:wall:
