Epoxy Floors Vary In Price & Quality
Why should I pay
for more for one epoxy floor system over another epoxy floor system?
When it comes to durability there are for the most part little durability
difference form one epoxy resin to another epoxy resin. There are additives such
as ceramic, aluminum oxide, or silica sand that will add to the abrasion
resistance and durability of an epoxy floor coating. Additives like fiberglass
reinforcing may be added to that will increase flexural strength and thus the
durability of the resinous flooring system this is found most commonly in
chemical containment and chemical resistant coating systems.
The areas where one epoxy floor coating system is better than another epoxy
floor systems is seen more often in chemical resistance, deterioration from
Ultraviolet light, speed of catalyzation, and viscosity.
A standard epoxy floor resin will hold up to common household chemicals and
automotive fluids. A chemical resistant epoxy floor coating will cost typically
50% more but will hold better to regular exposure urine and bleach and is
recommend for bathrooms, locker rooms, shower areas and kitchens. Novalac
epoxies are the next step and are used most commonly in area subject to chemical
attack in chemical containment areas, such as secondary containment and battery
charging areas, as well as chemical manufacturing and processing facilities.
This is not to say that while able to withstand exposure to a given chemical
such as sulfuric acid, found most commonly in fork lift batteries, that there
will prevent discoloration of the coating.
One of the weakness of resins such as epoxy is ultraviolet light. UV exposure to
synthetic resins plastics and rubbers will cause at the minimum drying out of
the resin lessening the flexibility of the polymer and may eventually result in
cracking. The other side effect from UV exposure is in the form of yellowing or
discoloration of the resin. These two issues can be seen with epoxy floor
coatings as well. Generally the drying out of an epoxy resin on an interior
application will take decades to become brittle enough to effect durability. In
the case of UV stability the effects may be seen in a matter of months or years.
Roughly 25% manufactures offer a interior UV stable epoxy floor coating. These
typically come at a 20 to 50% premium over standard epoxies but may be worth the
investment. UV discoloration happens most quickly under natural sunlight.
Fluorescent lighting is second in it’s ability to discolor epoxy coatings,
followed by metal halide, and sodium vapor followed by incandescent light.
Second to the light source is the amount of lighting and the distance of the
light source is from the flooring system. High intensity low hung lights will
more quickly discolor an epoxy floor than less intense higher hung light
sources. After considering the lighting of the area to be epoxy coated the
second is the level of traffic and abuse and the expected recoat cycle. If an
area is to receive high fork lift traffic, exposure to steel wheel traffic and
or steel shavings an lower cost epoxy floor coating may be a better option than
a UV stable epoxy floor coating since the epoxy floor will likely be recoating
in less than 5 years and any yellowing of the floor will be limited in this time
period and then covered up with a new application of epoxy flooring hiding the
unsightly yellowing. If on the other hand your epoxy floor coated area is a
light traffic area or a showpiece area it may be worth the extra investment for
a UV stable epoxy floor coating resin.
The second biggest factor to chemical resistance affecting the cost of an epoxy
resin is the speed of catalyzation. When it comes to driving it is said that
speed kills. In the world of resinous flooring, speed costs. Some manufactures
offer the same resin in standard dry times of 8-12 hours also offer a fast cure
version of the same product of as little as 4-6 hours. If you have a short
installation window for you industrial coating where your time is more expensive
than the additional money for a fast cure resin. It is important to note with
the decreased catalyzation time and increased cost is likely to decrease UV
stability as well.
The last of the major factor affecting the cost of an epoxy resin system is
viscosity. There are some manufactures that offer low cost 100% solids that work
well for most applications but in order to keep costs down they may contain
fillers that create a much higher viscosity and limiting their ability to self
level and thus smooth out rough or eroded concrete. In some cases it may require
as much as twice the epoxy to smooth out the same surface due to the thinner
viscosity epoxies ability to self level and the final appearance of the floor
