The plywood deck had a number of soft spots due to ponding water and failed waterproofing. We repaired the rotted sections and flattened out the low spots and installed Life Deck FM (Fiberglass Mesh) waterproofing system (kinda like a surfboard skin). The plywood is coated with a primer and then a fiberglass cloth is embedded in resin. Texture coating tops the resin to provide a non-skid surface and finished with a color sealer top coat that provides UV protection and uniform color.
