I'm trying to fix a few holes about one inch each in size that my tenants left as a gift before they had to vacate. I will outline the steps I intend to do and is somebody disagrees or have better suggestions, PLEASE let me know: I will fill each hole with a fiber glass filler and let it dry completely. Then I will sand it down super fine. After that I will spray paint the holes with a matching high gloss color. When this spray paint dries I will spray a coat of gloss gel coat on top of the paint. Thank you.

 

sand surrounding area to be repaired so glass/gelcoat will adhere. if hole is emty(plug knocked completely out) try to use adheasive on back side through hole and work a thin piece of fiberglass through to hold repair. let dry!!! apply glass-gelcoat to area as thickly as needed. allow to dry.sand hole repair flush(use glass filler as needed). apply tinted gelcoat as finish if available. there used to be a repair kit for these things but i haven't seen one in a while. Check at a home imp. store. I don't think the glass filler alone will stay in place. Good Luck.

 

All the gelcoat I find is clear (no color). How can I make the repaired area match in color the rest of the shower ? You don't make any reference in your response to paint. I'm a bit confused as the shower's color is actually Almond. Thanks for your time.

 

if you don't know who built the shower surround, then a diy store may have a repair kit for almond colored fiberglass surrounds. there is really no perfect way to ever match existing colors/paint etc. you just do the best you can. any paint you apply to the fiberglass should have a flex additive in it to allow it to move without cracking. either a plumbing supply that sells that type surround, or possibly an automotive paint supply store, may have tint available to color match the gelcoat. most new cars have the bumpers painted with the flex additive. automotive stores also deal with fiberglass cars and parts (corvettes) so they may have a better knowledge and supply of what you need. i have actually repaired a stall like that, but it has been several years and the repair kit may not be available. HOPE THIS HELPS!
