Mastic vs. Thinset

I have a shower/tub surround that will be re-tiled. 2 of the walls have cement board. The third wall was not damaged enough to re-place. It appears to be plaster over metal lathe.

I am hearing different oppinions on tile adhesive. Can you tell me the pros and cons to both? I believe that since I have cement board up, thinset is best. Am I wrong?

Thanks in advance.

Dan,

I will copy this to ceramic but my suggestion is to use mastic adhesives in non-wet interior areas only. i don't recommend the use of mastic in stand up shower stall walls nor on shower floors. Mastic adhesives are generally used over gypsum wallboard or cement backer board walls on countertops and bathroom walls.

For all other areas, especially in wet areas, thin set mortar is recommended. It has excellent adhesion and can dry quickly for application of grout. Provides more solid base for tiles.

Hope this helps!
