FliteskinTM can be attached to a balsa or ply frame in three different ways: with Elmer's UltimateTM polyurethane glue, with a good quality contact cement or slow curing CA (Cyano) glue. In every case the areas to receive the glue need to be sanded with 180 grit or similar.

Polyurethane glue: Cut the sheets to fit 1/4" to 1/2" over the leading edges and wing tips, sand with 80/100 grit the areas of Fliteskin that will be in contact with the frame and especially the edges. Apply glue only to the frame (ribs, spars, etc.) After positioning the skin in place, secure with tape, pins and weights. One method is to pin strips of balsa or spruce to the ribs and spars, holding the ends with small clamps. Use a sheet of wax paper in between to avoid accidental bonding. This assures the skin is held tightly against the wood frame while the glue sets (about 4 hours).

Once dry remove pins and trim edges with scisors and/or sand paper. Excess dry glue sands easily.
Contact cement: using good cement like PlioBond assures a strong bond that will not be affected by temperature changes. Follow the instructions on the cement container, making sure that the wing is flat on the building board when placing the FliteskinTM over the frame.
