Here's a question, what is the wall made of next to the toilet? Why isn't it just fiberglass like the rest of the bathroom and easy to clean? It also tends to want to mold, does anybody know what it is and why they didn't put (or leave it, if it is a coating) fiberglass on that wall?
You have a Standard Scamp
side Dinette, right? I believe they used a product called Smooth Panel Board
. My Fiber Stream
has it on one wall in the bathroom. It is a very common product, used in the Mobile Home and RV industry, in kitchens and bathrooms. It is supposed to be water resistant, and has been used in shower stalls and as back-splash in Mobile Homes since the 1950's. It is a sprayed-on Melamine coating over thin "hardboard". It was probably used because of the way the divider wall between the bathroom/closet and the rest of the trailer is constructed, as a load-bearing wall, with an internal frame to support the roof.
The Melamine coating is thin, and you are not supposed to use anything abrasive to clean it. Any scratch on it will expose the core, which may be why you have mold. The surface might be fixed if it is prepped and painted with either Melamine Paint
or Enamel Paint
. If it is badly damaged, then it needs to be removed and replaced.
