Sealing of foamboard.......

StrogeyOGR Forum Member

Question for those of you that are expeienced with using Elmers foamboard. If the edges of the board get wet will the internal foam absord the water and in tuen distort thr surface? If so is it possible to seal the edges with anything in order to prvent this from hapeening? I ask because I have edges that will be eventually have scenic materials up against them and am worried that the foam will absord the water from the materials or the glue and swell. In most cases this will be Bill's Scenery Fiber which has quite a bit of water absorbed into it. How about the surface of the Foamboard. The same scenario exists. Fiber may be applied to the surface. Will it absorb the water? And if so can it just be sealed with clearcoat of some sort?

Thanks in advance folks!
