Finishing Recommendations and Load Span Tables 1. Further Finishing Not Required Regular SkidGuard is a finished product with overlaid surfaces requiring no further protection. The overlaid surface is superior to paint and stain in that it minimizes checking and grain raise in the wood underneath. However, the surface can be painted for aesthetic effect. 2. Painting The overlaid surface of Regular SkidGuard is an excellent base for paint. To ensure that no trace of the release agent used in manufacturing the product remains on the surface, clean with toluene, Socal #2 or a similar solvent and an abrasive pad (nylon or aluminum). This will assure maximum adhesion of the finish to the surface. After the surface has dried, apply two coats of exterior deck enamel. Since enamel tends to reduce the slip-resistant properties of the surface, the addition of sand to the top-coat of enamel is recommended. 3. Edge Sealing In exterior applications, the edges and ends of the panel should be sealed before installation with a good quality pigmented exterior polyurethane resin finish. Clear polyurethane sealers are not recommended for exterior use. Load Span Tables Allowable Uniform Load per square foot (PSF) for dry condiftions is shown in Tables 2 and 3. For wet conditions, see Tables 4 and 5. Figures shown are for storage, marinas, and commercial use. For Residential deck and balcony applications, refer to Table 1. 1,2,3 Table 1 Maximum Spans (in inches) Based on American Plywood Association recommendations for "feel" under normal walking conditions.
