Cracks in bathroom walls

[Jeremy9107]

Any suggestions on how to fix the small superficial cracks that have developed in the walls of my bathroom? Is there a filler product out there or some other home remedy to erase them?

If it is fiber glass you can grind a "v" in the crack and use a product called mar-glass..this is a fiberglass reinforced filler be sure and sand the surrounding area with 150 grit apply mar-glass to crack and let dry then block sand with 150 grit, then 220 grit then 320grit prime it with automotive primer let dry then wet sand it with 800 grit....wipe clean then paint it...also look up mobile touch up companys and they will come out fix and match your paint all for you..hope this helps..

I've heard it's ABS....

The abs plastic degrades with age and gets brittle and shrinks a little. That leads to cracks opening up. You can sometimes stop the progression of the crack by drilling a hole in the end of it. There is very little you can do to restore the properties. If the curvature is not too tight you might be able to cover the defects with vinyl bathroom wall "paper". Some brands have a little stretch and work better than others. I have also seen vinyl with pressure sensitive adhesive cover the problem.
