TotalBoat TotalTread non-skid deck paint can be applied to concrete patios that are free of any surface contaminants. TotalTread will have a harder time achieving a proper bond if the concrete surface is extremely smooth, though. It may be necessary to abrade the concrete to a rougher surface prior to application. Applying a concrete etch will help improve the bond strength, then priming with an epoxy primer is strongly recommended to promote the best adhesion.
It should be noted that on concrete that is omitting higher amounts of moisture, the any coatings may delaminate from the concrete surface.
The expected service life of TotalTread on an exterior patio would not exceed five years. It is recommended that every 2-3 years, some maintenance will be required to maintain the most consistent finish. Remove bubbled up areas, lightly sand or scuff the surface, and reapplying a fresh coat of TotalTread, as directed.
