Epoxy and Urethane Floor Overlays Floor overlays are typically trowel applied or self-leveling materials that are meant for more severe service conditions than a 20 to 30 mil coating system.  They are anywhere from  3/32"  (100 mills) to 3/8" (375 mils) thick.   These are heavy duty, industrial floor systems used in chemical process, hot water or steam wash down environments, high impact and abrasion conditions, heavy wheeled traffic  service or any environment that would subject a floor to considerable wear and tear. Overlays can also be used to recondition and correct defects in floor slabs that have been worn or spalled over the years.  Self-leveling (SL) floors are fluid applied and are typically Epoxy SL or Urethane SL resins.  The floors are 80 to 125 mils (1/8" thick) and would be applied over a heavy primer to minimize air bubbles.  Topcoats and non-slip textures are optional. Other types of overlay floors can be either trowell applied Epoxy or Urethane resins with sand or graded aggregate fillers that are finished like concrete using a flat trowel. These types of floor overlays are typically 1/4" to 3/8" thick.  Primers are used dependent on the resin base.  Some products are self-priming,  Topcoats are normally used to seal the surface or used with a broadcast over top and back rolled to add texture for a non-slip surface.
Self-Leveling Overlay The existing concrete slab of a bunker had deteriorated from constant dumping and abrasion from a front end loader. A  1/2" self-leveling cementicious urethane from Rock-Tred was screeded over the entire slab as a wear surface and has continued to function after more than three years of daily use
