a mate of mine just applied the first filler coat to his hollow board ( ceder/pine )
and all these crater air bubbles kept coming up through the job. as im just about to glass mine, i was just wondering if there is any way to avoid this?
Pre seal the wood with a coat of thinned resin before glassing, wipe the board down to remove greasy finger prints and contaminasion, heat resin (epoxy) before adding hardner, glass on a falling temp and don’t over work the resin
glass it as the temperature (of the board) is falling. Use additive F (If you’re using Resin Research) to help the bubbles release the surface tension if you do have some.
“glass on a falling temp”
thats the best advice Ive heard in a long time
I get those nasty crater things once in awile
I knew it was from sun heating up the board (gassing) I like using uv hardner
I usualy glass in the morning when the wind is off
I guess I should do my lamming and sand coats in the afternoon
just do the gloss coat in the morning
