How do I fix my sink?

[bestfriend]

This is about a 3/16 inch hole in the bottom corner of the sink. How do I fix it? Whats the quick and easy way, and what is the longer, correct way? Thanks.

BF-

is it a hole or just a ding in the sink's gelcoat?

If it is a hole, tape over the bottom of the hole and fill it with thickened epoxy...then gelcoat over it.

The gelcoat is punched through, but I forgot to look and see if it goes all the way through. I wasn't sure what it was made of, thanks SD.

If it is gelcoat, then it is probably a fiberglass sink. In any case, as long as it isn't some of the slicker plastics...the thickened epoxy should seal a hold that size fairly well.

If the hole doesn't go through and it is just a shallow divot in the gelcoat... grind the divot a bit, wipe with acetone and then just gelcoat it. Deeper divots need to be filled, even if they don't go through.

bestfriend,
That sure dosen't look like gelcoat to my eyes.





My galley sink is stainless, but the head sinks are both of a porcelain enameled finish over metal. The best way to repair a porcelain chip is with a repair compound made exclusively for this. There are several out there - here's one I found after a quick search:

If it is porcelain and the underlying sink is stainless, and you've managed to punch a hole in the steel...I'd still be for filling it with thickened epoxy and then coating it.

TB-

How can you tell.... the photo is badly exposed and a bit out of focus...

Yeah - I know it's out of focus, but porcelain chips circumferent around an impact and the blackened base material looks like cast iron - a popular metal for porcelain enameled plumbing fixtures.

I broke up my old cast iron bath tub with a sledge hammer last year to replace with a whirlpool tub . . . that was one heavy tub, and this was the easiest way to get it out of the house. After laboring over that nasty job for an hour - I learned the physical properties of chipped porcelain over cast iron -

LOL...that's one way to learn about it... But cast iron is a wierd choice of materials for a boat sink... They're usually fiberglass or stainless steel.

Could very well be gelcoat over a dark glass mat material - most likely is. Most firemen I know are part-time tradesmen, so this should be easy enough for BF to find out.

I'll be down there tomorrow, place your bets....
