Resurfacing a Board Bottom

General Discussion
1

I’ve got this board thats about 6 years old and is a Magic Board for me.

Its a regular polyester/Clark foam board.

I can surf it into the ground for the next 1-2 years or I can try to extend its life.

I want to resurface the bottom.

Its yellowing on the bottom here and there so I thought I dig into a few places questinable places and patch it up.

However, I want to recondition or resurface the bottom.

I pulled it out of summer storage and there were these little salt volcanoes in scattered spot along the bottom emanating

from little teensy weensy pin holes.

(the board was stored bottom up in a hot garage)

Which means I’ll be sanding the bottom somewhat then applying a hot coat of finishing resin.

You guys got any better ideas.

Have you thought about measuring it carefully and making another one? If you do resurface, measure it anyway to make sure you end up with what you started with.

if it were myself i would Sand it down with 40 grit and sand it pretty far down and then use some 120 grit then i’d hot coat.

you’ve got the right idea.

however I wish there was an even better idea too.

I’d sand it back as Josh said, a little lighter maybe, 80 grit.

Chuck a layer of 2oz over and glass and hotcoat as usual.

That’ll save having to find all those little leaks, strengthen the board and give you a really nice finish…

Wrap the rails too, it’ll last another 20 years without affecting the performance too much…

As a collector of surfboards I can say that when you want to hang that board on your wall eventually, then to remove the yellow signs of water damage ( on a previously plain blank),you need to drill 1.3 mm holes(just make them small OK) about 1/4 in apart and put bleach down the holes. It whitens the blank and after you smear resin over and a quick polish, no-one would ever know…

Thanks for the reply guys,

I am divided over the 2oz reglass w/ rail lap vs. the major sand and hot coat.

You guys delivered thanks.

Brett,

I am intrigued by your bleach procedure. I have never heard of it before. Can you provide some more details? Do you use straight bleach from the bottle or dilute it with water? Do you flush out the bleach with pure water after it has whitened the foam? Can you control the amount of whitening, for example, if you don’t want it pure white but want it to match a board that has yellowed slightly over time?

Brett,

Thanks for the details. I’ve got a few boards that need something like this. I’m going to try it out right way.
