I have an older fiberglass pool filter where the outer layer of the
resin has worn away over time and now the fibers are exposed. I want to
put some sort of thick coating or paint (epoxy?) on it to cover up the
Does anyone know of something I could use on this that I can apply with
a paint roller and pick up at a Home Depot?
Do you have a recommendation on a product brand that's available at Home
And when you say "done", what does that mean? I don't plan on removing
this stuff once it's on.
I had already planned on the disposable roller. :)
They are unlikely to have anything. Ditto Lowes. Try a marine or surfboard
place. Or maybe auto supply like NAPA.
Both require a catalyst to set. Epoxy sets up slowly once the catalyst is
added, takes up to a day to get reasonably hard. Polyester hardens much
more rapidly - minutes - and the set up time can be controlled a bit by
using more/less catalyst. The curing process generates heat, BTW, so use a
shallow container for mixing and don't put the container in the trash until
all is cured.
Also BTW, there are two types of polyester resin: laminating and finishing.
Use laminating when you plan to add additional coats as the surface remains
tacky after setting. The finishing has a small amount of wax added; the wax
keeps air from the surface so the resin sets hard.
I would suggest going to a marine supply house/marina/boatyard. I
think you might be after what is known as "gel coat." I did some
repairs on a sailboat many years ago. Used epoxy and fiberglass mat,
then a special fiberglass paint, in my case. Can't believe your
problem is all that different.
