[quote]QUOTE: Originally posted by rrinker Well, all the benchwork is built, now it's time to fasten on the 2" foamboard tops. Everywhere I've seen, the preferred product seems to be Liquid Nails for Foamboards. I previously has 2 sections of 2x8' foam side by side with 4 crosspieces of wood to help maintain stability as a basic for my test oval. I used Liquid Nails and weighted the whole thing down with stacks of MR's (I have a pretty extensive collection of back issues) and left it sitting for 24 hours, then flipped the whole thing over and put it on top of a large table. When I went to take it all apart to make room to start building again, I found that the foam lifted clean off the wood with no effort, like it was never stuck fast. There is Liquid Nails strongly adhered to the foam (can't pick it off without gouging the foam), and there is Liquid Nails strongly adhered to the pieces of wood (ditto). So obviously is sticks to both materials, but seems to not stick to istself very well? What did I do wrong here, not leave it dry long enough? I am concernced here because those boards were some old pieces of shelving that I has, each board was 8" wide so there was a large contact surface. Now I will be trying to fasten a sheet of foam to a grid made from 1x4's, so the contact surface is only 3/4" wide around the perimeter with a crosspiece ever 16" on center. If not Liquid Nails, what shold I be using here? --Randy [/quote] Latex Liquid Nails will be fine. However I have personally found 24 hrs to be to short a time span. I did the same basic thing you did with a mountain and a hill after 24 they came right off. I finally said the heck with it and left it for 3 days. Now to pull it off I'd have to break the foam
