Watching Glue Dry is exciting!

[jacon12]

Thanks everybody. I glued the first couple of pieces down about 24 hours ago and weighed it down..

I knew those books would come in handy for something one day! But, I ran out of them and have held off glueing the last 3 sections down til I can find something to use for weights.
Hmmmm.... must be something around here..

Jarrell -

I used Elmers carpenters glue, and it seemed to dry pretty quick (overnight) between the foam and OSB base I had... But between the foam and the WS Roadbed I used, I could peel that stuff up for almost a week after laying it down without ripping anything...

How long have you had the foam glued down? Is it still
"sliding" on the plywood?

I don't know about LN, but I used wood glue and it dried overnight and seems to have a strong bond.

Hope it holds up.

BTW, your posts have been entertaining. You and I are at about the same point in the building process.

There's a long time between "stuck down so it's not going anywhere," which is only a few hours, and "rock solid." I take all my wife's cookbooks off the table at the first point, and then I'm quite happy to lay track.

Since foam doesn't "breathe" like most natural materials (wood, homasote, etc) it can take quite a while. The longest time I've had to wait for LN or wood glue to dry was two weeks! That's one reason I've switched to silicone caulk for gluing foam to foam and foam to wood: it only takes 1-2 days to fully cure and offgas.

Jarrell,

I've heard as long as a week or more - but that may have been under less than optimal conditions. Sounds like your surroundings are better than most...

I think I've read somewhere on here it can take upto 24-48 hours to dry all the way, this was because the glue couldnt 'breathe' between the foam and as its basically airtight in there the glue doesnt dry too quick. Dont take my word for it though.

I would advise not to keep prying it appart to 'check' though as this will weaken the bond although I know its not going to need to be that strong anyway.

I remember an old bumper sticker ...... "God give me patience.......BUT HURRY !!!"

Have fun & be safe.

Not!
How long does it take Liquid Nails for projects sandwiched between extruded foam and plywood to dry (bond) anyway? With books piled on top and in an airconditioned space.
