When all the edges are complete, the main field areas of the
deck can be coated (Figure 9).Figure 9. At the main deck, a bedding coat of fresh
resin is applied in 4-foot bands using a short-nap paint
roller, covered with a full-width sheet of fiberglass mat, then
rolled again (left). Clean sand is then spread over the still
wet mat to provide a nonskid surface (right).
Using a new batch of resin and hardener, the deck is coated
in 4-foot sections. First, resin is rolled onto the plywood
using a paint roller with short-nap throwaway covers; then a
4-foot run of 2-ounce mat is laid, "wet out," and rolled to
remove any air. The mat is precut to save time, and the edges
are frayed to feather the joints and make them less visible.
The mat is non-woven, so fibers can be pulled out by hand to
thin or fray the edge. Before moving to the next 4-foot
section, clean sand is broadcast by hand over the still-wet
surface to create a nonslip texture. Work proceeds in 4-foot
increments until this first coat is complete.
The fiberglass doesn’t fully set up for about 8 hours
(faster if it’s in direct sunlight), so the surface
should be protected from all traffic, including children, pets,
and curious passersby. The resin will cure completely in
