I'd like to know if liquid nails can be used to install leash plugs. As far as I know there are three different types of liquid nails- epoxy, super glue and silicone sealant. On the package af one of them it states that it can be used with fiberglass and foam. Can it be used with both eps and polyurethane foam ? The last board I made was a materially hybrid of polyurethane foam and epoxy resin.
Hey tony,
Drop a little on some spare chunks and see what happens. Report back on your plug install. I’m interested in plug install alternatives for eps. Thanks. Mike

i've used 5200 Marine Adhesive to install a leash plug in one board. no problems. it says once you open the tube, you have to use the whole thing because it will all set... NOT TRUE i installed the leash plug over a year ago and just went back out and used some more. i couldn't get the lid off so i cut a corner off of the tube and it squeezed out fine. i plan on cutting the other corner next time i need some and maybe getting some more after that from some holes poked in the middle of the tube... the leash plug install doesn't look bad either. after the glue had set, i cut off the excess with a razor blade then sanded down the plug/glue. thanks Herb Spitzer for the heads up.
Howzit tony, If you are trying liquid nails,use the sub-floor and not the project,it isn't near as strong as the sufloor.Aloha,Kokua
I'll second that Kokua. Don't ask how I know. :)
Isn't "liquid nails" a type of poyurethane? If so; there's a good chance it would react with EPS. I'm pretty sure they are making an acrylic formula now as well.
The subfloor adhesive may not stand up to prolonged immersion. I’ve seen it fail in the rain more than once. What’s wrong with a couple of glass patches and good old epoxy? Even the five minute type works. I glued and nailed plywood sheathing at the same time and had three days of rain (on & off) only to come back and see the glue had failed. Admittedly, this could be due to lack of curing time because in times of no rain the stuff has worked very well.
ps. if you have a slightly oversized hole and rough up or scribe the inside of hole to create “keyways” for the epoxy to fill in, with two layers of 2 or 4 oz. glass I’d doubt there would be any failures.
pps. Funny story, in 1990 we did a house right on the beach with 1x6 cedar horizontal siding with no batts! ALL MITERS! inside and out! This is a three story house so you can imagine how many courses there were. At the time the best choice of glues for the miters (OR mitres) was the subfloor adhesive. By the end of the day our hands were covered in glue and we tried many types of solvent for removal. WD40 worked fairly well but not complete. One day after saying screw it to the lengthy clean up, we split and stopped at Arby’s roast beef for a couple of sammies. I’m driving while I hear my buddy start laughing and he shows me his hands…totally clean!!! No residue at all. We trip out on this and then realize that if the glue wasn’t still on our hands then… Arby’s, nature’s solvent.
