I have a large fiberglass laundry tub with a divider in the middle, making it a double bowl affair. I want to remove the divider and glass up the "wound" so the sink can be used to wash the doggies. What do I need to use for this? Can I use resin, then gel coat? Do I need to use cloth, matte, or fibers of any kind? What type of resin? Where do I get gel coat? I plan to paint it after I'm done, so that will protect the work I do. Would the cheap polyester resin work? I guess this would be just like a boat repair, of which I know zip.

Thanks!

Do you know it's fiberglass and not a glass impregnated plastic?

And the next question... are they two separate sinks, or one with a wall for separation?

The tubs I know of are not fiberglass, but a plastic.

This is an old, HEAVY fiberglass tub, and it is one piece with a divider, not 2 sinks stuck together. I have confirmed the material and that what i want to do will work, both structurally and cosmetically, I just don't know what materials to use.

use the cloth - gives it the most strength
also, when you remove the center divider, you are removing support
you may want to a steel strip on the "long" sides, about 2/3rds the way up, to keep it from bowing outwards

This is an old, heavy walled unit that won't flex much, but I have considered glassing in some metal or wood if it appears weak. I am installing this without stoppers in the drains (fixed strainers only) to keep anyone from filling it and stressing the sides, so that's not going to be an issue.

My concern is making the sides smooth and water proof, as well as making it pretty enough to please the boss.

Wouldn't it be cheaper to just replace the tub, with a new laundry tub, then going through the hassle of fiberglassing, and not knowing if it is going to hold?!

Just food for thought...

"The PRE10DR"

I agree, a new laundry tub can be had for cheep, probibly twice the cost of materials

I can't find a large one without a divider. So far I have $0 invested, so I'm doing pretty good. I also have some resin and cloth, so after it's all said and done I'll probably have less than $20 in it. Can't get a new sink for that.

personal satisfaction
I prefer to do many things myself
anyone can buy stuff

if you have a local habitat for humanity store they might have somthing aswell and stuff from there is dirt cheep (locally it is anyway)

cloth is strong
but it doesNOT stick well to existing F/G
mat is better for a strong bond to exist F/G
you MUST remove the gel coat or paint and ruff the F/G
or nothing will stick
then wet the surface with resin
a layer of mat then cloth
repeat intill about as thick as the tub
6'' wide should work
you can taper the layers wider on bottom
to avoid a thick ridge

you want to do it layers all at once
to avoid sanding between layers

you can get fab-mat [mat and cloth together ]
use bonding resin not casting

Question wonder and be wierd
are you kind?

i was just at Menards and i happened to walk down the sink isle, and i did see that they have a large open utility sink with no divider for $57

Was it as large as 2 big singles side by side? That's what I have. I have looked and haven't been able to find one like this. Thanks for the info, though.

it did seem to be an odd size, kind of in the middle i'd say, but just as deep as the deepest one
