Question:

I recently bought a roof kit from you. I am in the process of replacing the it now. I have run into bad plywood and have removed it. I am looking for recommendations of what type of glue to use on the plywood to the polystyrene roof.

The adhesive I recommend for your Polystyrene and Plywood roof is the Alpha Systems Anti-Wicking Adhesive for RV Roofs # AL97CV. This seals the edges of the plywood and expanded polystyrene and comes in a 5-gallon bucket. It covers 160 sq ft per gallon so you should only need this one bucket.
