Splinterlock technology is a high build elastomeric coating designed specifically for new or old damaged wood and concrete surfaces. The unique formula provides long-lasting protection against moisture and the damaging effects of the sun. Designed to expand and contract along with the substrate while offering excellent scuff-resistance for heavy-duty foot traffic areas. Contains a highly effective mildewcide and algaecide and will lock down splinters and bridge dimensionally unstable cracks on old damaged wood surfaces. Use Duckback Anti-Skid additive to provide an attractive skid-resistant surface on decking, boat docks, stair treads, ramps, and walkways. Coverage: 75 to 125 sq ft per gal on most surfaces, 50 to 75 sq ft per gal on extremely damaged surfaces. Dry time: 24 to 48 hr for foot traffic.
