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
