Clearco 877 is an alternative I and many other Weasel folks use: more

A word of caution with the new 3M-77. I have read several post stating that if you mist it on it will not melt the foam. Well I did a few test sections trying this method. The first one I misted it from a distance but applied a lighter coat than I would usually apply. I left it a day and checked it. The foam was fine, no melting BUT the bond was not very strong and I believe it would surely delaminate after some time. here

There are a lot of adhesives that work well with EPS foam, but there don't seem to be a lot of SPRAY adhesives that work well with EPS foam.

I can do without 77, if I can figure out a good way to tack down a strip of fiberglass to a cores leading edge before I vacuum bag.

i'm building my first scratchbuilt right now and ran out of GWS contact adhesive this morning. i tried some welder i had on hand on some scrap peices of dollar tree readiboard, but it kinda ate the foam. i used welder on the spar of my slow stick and it ate the leading edge pretty good. it did make a nice little groove for the spar, but it sure wasn't pretty. is this the desired effect of using welder on foam? i would think super 77 would have a similar effect on foam. i have a can, but the nozzle is clogged atm. i'll give it a shot later if i can get the sucka sprayin' again.

i went to michael's this afternoon and after staring at a entire wall of glues, i finally found one that looked promising. its called "CraftFoam Glue" and its made by Beacon. i paid $3.79 for a 2oz bottle. directions call for application to one peice of foam, wait 15-30min, then press parts together. to use glue as contact cement, apply to both peices. this is recommened for hard to bond situations or when foam is likely to lift (thats us! ). uncured adhesive cleans up with soap and water.

a search of the scratchbuilt forum brings up a couple of mentions, but i'll not detail so i'll give you my perspective. so i tried it out on some scraps first to see what its all about. its white like elmer's school glue, but a little runnier. spreads very easily across the readiboard (paper removed) unlike the gws that got sticky as it speaded thin. a little bit goes a long way. wiped right off my glove with denatured alcohol and a paper shop rag. let stand for 25 min. both peices appeared almost dry. sammich'd the two together firmly for about a minute. initial impressions are very good! i can't pull the two apart with reasonable force! no idea the long-term reliability or the effects of temperature or humidity, but since their "hold the foam" adhesive claims its not water proof and this has no mention, its reasonable to assume its at least water resistant. no fumes, no mess, non-toxic, appears very strong and flexible. (contact cement flexible) more
