How to tell if bathtub is acrylic or fiberglass?


Hello. I'm not sure where I was suppose to post this in the forums so my best guess was here. I have a tub/shower combo with some hairline cracks in it that I need to repair. I was wondering if there is a way to tell if the material is acrylic or fiberglass so I can determine the correct repair procedure. Thanks

Fiberglass has a reek to it. If you are familiar with that particular bouquet then a close olfactory examination will tell you.

I never know fiberglass had a bad smell to it. I honestly don't smell anything because I just cleaned it. Is there any other way to tell?

Fiberglass would display what the name suggests if you were to look at in on edge. Either resin and fiberglass cloth or matting is laid up in a mold or more likely for a tub surround, a slurry is sprayed into one over a gel coat layer.

An acrylic tub and surround would be vacuumed formed over a mold and would be formed out of a sheet of plastic.

You need to find a cut opening.....fiberglass will have a few fibers....acrylic will be smoother.

If you can see under it....it's real obvious.....the underside will look like a bunch of straw compacted if it's FG

You can take off a knob and the escutcheon plate behind it then you will be able to examine the edge of the cut hole.

If it's cracking it's from the tub not being supported properly.
Applying some form of coating is not going to do anything.
