Lap sealant and styrofoam


Recommended Posts

  I am curious if anyone has used Doctor lap sealant to seal styrofoam to a rv body. Going to be wintering In Montana this year.     I am thinking about using lap sealant to seal the styrofoam to the body. The sealant can be re removed fairly easy if needed.

   The styrofoam will be on a frame work for stability.

  Also what glue would good to use blue styrofoam together.

It depends on what you are gluing it to & how long you have for it to dry.  Here is a You Tube video showing the results of a bunch of different glues.

I used Lock tight PI Premium Fast grab to attach blue foam to fiberglass.  It is tacky enough that it holds almost immediately.

   A few days ago I put some dicor lap sealant on some blue styrofoam. It has not disturbed the styrofoam.

  So this is to seal the styrofoam to the fiberglass body where I can. I do have lots of other stuff to be doing.  But we are supposed to have 39 degrees on Monday night I think.  Rather get started early and figure out what I want to do. Before the grass turns white.
