This is a legitimate concern, especially when considering a finish for your pool deck or patio. Of course, safety is a foremost concern in all aspects of any Kern Enterprize Inc. project. As a rule, we use specialized additives in all of our sealers that help provide traction and grip, without diminishing the cosmetic appeal of our concrete. This additive greatly reduces the slickness of the concrete's surface by introducing a sand-like, yet virtually invisible texture to the sealer. This, coupled with the physical texture of the concrete itself, makes for a surface that typically is no more hazardous than comparable unsealed hardscape materials.
