if i wanted to glass both sides of my board would i do the two sides seperately?

2.) Could i just stick a graphic on to the wet fiberglass, then put another layer of glass on top of it?
(so the graphic would be sealed between to layers of glass?)
3.) prices to cover a mini? say 2 layers per side, so 4 in all? 32 inches long, about 9 wide?

well you i bought my Fiberglass at TAB Plastics in a 1 foot wide strip, 4 yards long, and along with a quart of polyester resin, and catalyst, along with a three disposable measuring cups, a dozen stir sticks, an application squeegee like thing, it was about 40 dollars total. for a mini you would need two yards and the other stuff, so it would be 35 dollars. i dont see why you would want 2 layers a side. wood would be a better stiffener that FG, i use FG to reinforce strength, and alowing flex, but not alowing overflex.

for your Q about the graphic. put the graphic on the board, seal it with some clear coat, then glass right over it. you can put it between coats, but fiberglas clears, and stays clear if you use UV treated epoxy, then it wont yellow.

Flanelman answered my question too! :

haven't read this one yet on here...

How long should i let it cure before i should ride it?
i put the mat on, glassed that, let it sit for 24hours
after the 24 was over i cut the extra mat off and added another layer of glass.
plus i can't really have it indoors other than the garage but that isn't warm...

thanks a lot minnesota winter....

well how long did let the first layer of Glass cure? i would say 48 hours would be a good cure time in the cold. if you need more, then let it sit longer. the colder it is, the longer is will take. just let it sit for 48 hours, then if it isn't cured yet, wait a day. you should be able to ride it fairly soon.

the key is that is isnt tacky, and is solid in the middle.

being out in California in winter is great. it is raining, so board building is as close to riding as i can get. i don slide cuz i dont have the gear.

ya... let the first one cure in the garage (40*) for about 5-6hours then in my room for 15 hours or longer, then put the second layer on...
the garage is gettin some 20* now over night... so i think i may need this to sit for a few days....

i save excess epoxy sometimes for little patch up jobs on my board, by putting it in the freezer, and it keeps for a few weeks. at 20 degrees it could take quite a while to cure as in weeks/months.

NNNOOOOO!!!!!!!good thing is jsut snowed again i suppose...

once the sentch goes away i'll be able to bring it to my room so it'll be plenty warm in here for it.

**duckhunt** · 02-19-2009 10:31 PM

well, i have the board in my room now and it get to sit in the sun for 6hours or so.
how long do you think it'll take to fully cure now?

where can you order rice paper online to print onto?

you can try here possibly
Rice, Wafer, Edible, White Paper 10 pack 8 X 11
but i dont want to make an guarantees, seeing as i have never done it before

Ok. Here's the deal. I have a board in my possession that I broke in half...... length wise. I don't really know how. Anyways, I was wondering if I could sand the broken innards of this board and apply a sheet of glass or two in the middle. Would the glass and epoxy hold the two pieces together sufficiently for, say, a 170 lb person? Would this method even be strong?

now that you have written this, you must put up a pic. i have got to see this. i am thinking that is broke bolt hole to bolt hole, not delamination. if so, then i wouldnt touch that. FG may fix it, but it could be a lost cause. i guess if you look at it this way, you have to V-Lam the broken Deck, then FG to really hold it together structurally.

i guess, with enough glass it can be done... i just wouldnt try it myself, and have falls hopes of inevitable success.

This picture is on my profile also.

As you can see, there is a top half and a bottom half. I was wondering if I could sand and fiber glass them together. And if it would hold. For even just a bit.

that is an easy fix. just pretend that you are laminating plywood, just that the wood has already been shaped and finished. epoxy that up, and you should be fine. i would epoxy,then clamp it, so it will form correctly.sand the inside only if you think that it will help the epoxy stick better. after the two parts are attaches i would then apply epoxy to the sides to seal it. if you want, you can wrap wi with Fiberglass, but the main prob is that it delaminated, so re-laminate, and then seal the edge. good luck.

the board seems to be is bad shape though. if the wood has gone bad, then you will need to sand it down. if it is too thin after you re-lam it, then wrap it in FG.

alto now that i really studied the pic, the nose will not have enough wood, at least thats what it looks like. what you might do is add plywood to the middle.

honestly i have seen board where the bolts riped through the bolt holes, and noses split 10 inches down the middle, as well as board held together with epoxy and sweat, so you do have a chance at saving it.

it might be wiser to just start from scratch, and use the board for a model.

Yes. It has seen better days. But I can get all the fiber glassing materials for free and I'm fairly sure I don't have any 1/8th inch birch ply just laying around, so I figured experimenting with this would be fun.

Since the board is delaminated, if I tried to put more or less concavity in it when I relaminate it, will it hold?

if you can glass it for free, then by all means, do it. just use alot of glass.
