I had an issue with a lot of small fish eyes all over my deck’s hotcoat. I plan to fix it by using a soft squegee and going back over the deck to fill in the small holes. should i sand the deck first very lightly before i reapply a little bit of resin or should I leave it unsanded?
Other Idea… from what I read it seems that even with a new coat that some of the fish eyes might fish eye a second time… i hope not, but if they do I was thinking about spraying them down with some clear acrylic spray paint and then sanding the deck. the acrylic paint will be down in the holes and therefore will not get hit with my sanding pad.
Does any of this sound like a disaster waiting to happen?
I have some regular poly suncure resin… is that what you are recommending that I put in them? Why not use epoxy?
I have a lot of i guess what you would call “fish eyes”. They are small about half the size of an ant and there are probably about 100 of them. It would be hard to tackle each one individually so I was thinking about using the squegee to fill them in. I kept things pretty clean with new buckets and brush so I am guessing that perhaps it had to do with the temp?
use sanding resin; if you do not have UV cat sanding resin, you can do it putting styrene with wax.
If not, use the conventional sanding resin…and wait.
The way I tell ya is the easy way, less time consuming and labor.
You can sand down all the damaged hot coat with a heavy grit sandpaper; but too much labor intense (and a bit more weight in the end) then apply another hot coat
sometimes the tiny ones are not really fish eyes and more about some dust or like that that do not let the resin flow right and stabilize it
So when you ask advise your going to have to make it 100% clear what you are useing ,EPOXY or PE, . Also good idea if you post a picture of the problem. If you don’t your going to get answeres and advise for both and will just be confused !! You did not give enough information so all answeres are invalid !!!
Sorry… i thought that fish eyeing was specific to expoxy and then once I realized that I forgot to specify I appologized for forgetting and indicated that the board was eps… I just hotcoated the bottom and it looks great. I think the board was gassing last night when i did the deck.
Thanks to everyone for their help as I am new to swaylocks.
Without seeing your fish eyes, or knowing your sanding abilities etc, etc. here's what I do: I just sand the board down to the fish eyes....no big deal. Most guys don't sand there hot coats enough anyway. if you look closely you will see the interior of the fish eye still has a little hotcoat on the fiberglass...remember the hotcoat is just there to fill the top of the weave. it's not structural, and it's only purpose is to fill any little voids in the lam coat. it makes the lam coat waterproof..in theory. Epoxy or poly is just glue for the fiberglass...that's all it is glue
So just sand the hell out of it, and carry on as usual. next topic will be how to put a clear coat over the sanded hotcoat.
get back to us on that one after you have read the archives.
wait.... now you think it wa gassing? Boards only gass when the temperature is rising.. So if it was cooling off...err no gassing.
explain: When board core cools, the board sucks in air, this is agood time to hotcoat or glass. When board heats up, core heats up too, and blank puffs gass....not good time to hotcoat or glass.
