Question: How should I make a mountain with foam insulation?
Frankie writes from Newtown Square, Pennsylvania: "Mine is more of a hobby question. I'm making a mountain for my G-sons train set. I'm using PINK insulation. In piecing the mountain together - 1. What type of sealant can I use to brush or spray on to fill the cracks? 2. What paint can I use?"
Answer: Sounds like a great project. I assume you mean PINK FOAMULAR™ insulation (not PINK FIBERGLAS insulation). Adhesives, paints and other materials used with all extruded polystyrene (XPS) insulation products such as FOAMULAR insulation MUST be petroleum free. Have fun!
