Sealing a poly blank question

General Discussion

Seeing if you guys seal your polyurathane blanks before glassing.  If you do what do you use. Ive heard sealing artwork with that future floor cleaner, so is that what you use to seal the blank. The purpose for me wanting to seal the blank is to keep the foam from sucking resin giving me the lightest board possible. thanks

You don’t need to seal poly.  I believe that future floor cleaner has wax – my bet is that it will cause adhesion issues.

For a lighter board, laminate / hot coat with epoxy.

I just seal for better bonding especially when using flat weave cloth, 3 parts resin to 1 part styrene so it flows and soaks in evenly.  This method won’t reduce weight.  I agree with da5 that any type of quick seal to prevent soakage and reduce weight will compromise the bond.

[/quote] future has no wax in it...........is doesn't effect bonding..............great for mixing paints with ,instead of using water.

it also seals airbrush work so you can run tape over it w/o mad pull offs.

as far as what gene said i agree to a point..........better bond and it doesn't make it any lighter.............i think you still owe me lunch gene ?........lol.....jk.

Thanks for your comments guys I apprecaite talking with legends. Anyway so your saying no benefit sealing a board with future to make it lighter, how about say spraying entire board white using say acyrlic paint thinned with future or whatever. You think that would make a board lighter. I use primarily eskimo foam and us blanks and i glass em 4oz top, 4oz bottom s cloth and pull em as dry as I can without being too dry but I cant seem to get that ultra light weight that I feel when i pick up a pro’s board. And yes to da5ids comments I have used eps and epoxy with the same glassing schedule above and that is on another level light. However at this point im just trying to make my poly boards as light as I can with that glassing schedule.
