Although the building plans do not specify fiberglass sheathing of the deck, I have decided to do sheathing not realizing the amount of work involved. It will however increase the strength and stiffness of the deck, provide added impact and abrasion resistance and an overall better resistance to wear.
To do the sheathing dry fiberglass cloth was positioned on the surface and epoxy poured directly onto the fabric in small puddles and the epoxy was then worked into the fabric using a plastic squeegee and/or foam roller to remove trapped air. When tacky another layer of white epoxy was applied and Peel Ply applied on the wet epoxy.
The use of Peel Ply in the sheathing process is extremely important. The closely woven nylon cloth of the Peel Ply is a release fabric to which epoxy will not adhere and is applied as the last layer of the sheathing process. When the Peel Ply is removed at a later stage, the textured surface will need no or only a little sanding thus allowing further layers of glass/epoxy, fairing compounds or coatings to be applied.

| The peelply provides a rough surface for bonding of the final layer of paint. |
