The primary methods are:
1. Handt roweled
2. Power troweled
3. Spray
4. Pour in place/self-level
5. Broadcast
Small areas, or areas with multiple obstructions, should be handtroweled.
Topcoat sealers should be applied to provide imperviousness and increased
densityw ith as mooth, easy-to-clean finish.
Large areas with aminimumofobstructions are best handled with power
troweling. The minimum thickness would be 1/4 in. (6.5 mm). The density
of the finish can be improved by the use of appropriate sealers.
For areas subjectedt oa ggressive corrosion,s pray application is
recommended. The consistency of the material can be formulated to control
slump and typeoffinish. This permits the material to be sprayed on vertical
and overhead surfaces including structuralcomponentswith thicknesses of
1/16 to 3/32in. (1.5 to 2.4 mm) as is suitablef or light dutya reas.
Economical and aesthetically attractive floors can be applied by the broadcast system where resins are “squeegee”applied to the concrete stab.Filler
or colored quartz aggregates of varying color and size are sprinkled or
broadcast into the resin. Excess filler and quartz are vacuumed or swept
from the floor after the resin has set. This results in afloor thickness of 3/32
to 1/8 in. (2 to 3mm).T hist ype of floori so utstanding for light industrial
and interior floors.
10.4 Epoxy andE poxy Novolac Coatings
The three most often used epoxy resins for monolithic surfacingsa re the
bisphenol A, bisphenol F( epoxy novolac), and epoxy phenol novolac.
These base components are reacted with epichlorhydrin to form resins of
varying viscosity and molecular weight. The hardening system employed
to effect the cure or solidification willdetermine the following properties of
the cureds ystem:
1. Chemical and thermal resistance
2. Physical properties
3. Moisture tolerance
4. Workability
5. Safety during use
