Hello,
I have a towel rack in my bathroom that has porcelain ends that appeared to be just drywalled?? or plastered into the wall. There is no bracket to attach the end to the wall. The fixture is countersunk a bit and not just flush with the wall surface. The bathroom is wallpapered so it is cut to fit around the end. I looked in your "Glue what to what?" section but it did not mention how to glue porcelain to a drywall or plasterboard wall. The house was built in 1971 so, not sure if this is drywall or something else. Can you suggest a product? Home Depot suggested a Hydraulic Cement. I picked up Drylock Fast Plug. However, this states it is really for masonry or concrete. I have not opened it yet as I am waiting on your response.
Thank you.
