I have a Fiberglass shower stall in my bathroom, and on the base of where
you stand to take a shower, there is a hairline crack. How can I repair
this small but needed repair without tearing out the entire stall and
replacing it with a new one. Can someone give me some advice on what is the
best approach to repairing this crack. Is there a product like at HomeDepo
where you can suggest I try using to repair this. Thanks for your advice!
Yeah, there are products out there, though a crack in the floor doesn't
sound good. I've been told that this is a repair that you really want
to have a professional do. There are people who patch tubs for a
Odd thought, but you might want to post this in rec.boats. As the other
person said, you might want a pro to do this work, but if you really want to
do it yourself, I'm sure you'll get some great fiberglass repair suggestions
in that other newsgroup.
Is the crack right through the floor and leaking? It might be a surface crack
that is not critical.
If the crack has severed the reinforcing, you will have to remove it to repair.
That kind of fracture will require reinforcing on the backside to repair. If the
crack is just in the resin/gelcoat and the glass fibers are intact, you can sand
the surface until you get to the fibers and then fill the sanded area til it's
back to the
same thinkness as the adjacent material. What you fill it with will depend in
what it's made of - acrylic, polyester, vinylester etc. I've never dealt with
acylic so you'll have to use google. For gelcoat, you can repair it as you
would a boat:
If appearance is not a major concern. A basic fiberglass patch kit should
do the trick. These usually come with a can of resin and one of hardner
plus an assortment of fiberglass fabric patches (matts). Get these at most
The resulting repair looks like a "bubble gum" or "big bandaid" patch but
it will hold the water in.
With a bit of careful sanding before and after applying the patch, and some
matching color Gel coat, you can blend it in reasonably well. It will be
difficult to make an invisible repair though.
Several layers of fiberglass cloth(from a boat products store) and epoxy
resin;do the *whole* bottom,not just the cracked area,then fill in with the
finishing coat of epoxy/filler(fumed silica).Then use a tub refinishing kit
from HD,the one for fiberglass tubs.
Hint;System Three(systemthree.com,IIRC) has a booklet you can download for
free that is EXCELLENT for learning about epoxy-glass work.
