Ask the Concrete Expert
How much epoxy do I need?
There are three main determining factors to look at when
determining how much self-leveling resin, most often 100% solids epoxy, a
concrete floor requires. The first is condition of the surface. A rough eroded
surface will require more resin to self level than a new concrete slab. The
second is preparation. Aggressive forms of preparation such as scarification may
require ¼ inch (250 mils) of material and shot blasted new or like new concrete
slab may require 12-20 mils of material. An acid etched or diamond ground floor
will likely require even less. The last factor to consider is wear. The thicker
a floor the longer it will take to wear through the floor coating. It may be
helpful in these cases to use a urethane topcoat.
Urethane has roughly twice the abrasion resistance of epoxy for the same dry
film thickness with some high traffic urethanes having four times the abrasion
resistance of epoxy.
Will welding damage my epoxy floor?
Yes, welding sparks can be in excess of 1500 degrees F.
Standard epoxy floors are designed to withstand temperatures up to 250 degrees
and some high temperature systems such as urethane mortars up to 360 degrees.
These sparks will result in burn marks not unlike cigarette burns. While most if
not all resinous floors on the market are self extinguishing if you get it hot
enough it will melt and burn. I recommend the protection of you floor with the
use of steel plates for weld areas or welding blanket for the occasional weld
available from your local welding supply company.
Why do some tires stain / discolor resinous floors?
There are occasions when high performance tires found on
exotic sports cars and aircraft leach an anti-ozonant compound, in the tire as
part of the vulcanization process, into the coating. This is rare however it has
been are experience that Speed rated Tires W, Y and Z are more likely to stain
than their more common counterparts. We recommend protecting your floor when
storing any vehicle for extended periods or vehicles with W, Y and Z rated on
parking pads as prevention.
What can you do to improve the quality of installation and save money on
Industrial floor coatings are designed for durability,
chemical resistance, concrete restoration, and appearance. Most are far from
user friendly and not designed for do it yourself applicators. Application
consists of a great deal more than rolling on a coat of paint. Helping an
installer control the application environment can greatly improve the results of
the coating installation. While installers can work around these issues such as
by using cold temperature products on cold concrete these will add to the cost
Quoted dry times are based on 75 degrees F and 50%
Relative humidity. The range of 60-80 degrees F is generally
acceptable for most applications. Colder temperatures will require
increased dry times, warmer temperatures will reduce dry times, but
may reduce the ability of some products to “self level”.
Adequate lighting is necessary for the best
possible application of product. Especially in the case of new
construction temporary lighting may not be sufficient to highlight
application flaws that under standard lighting may become more
In all applications 110-volt electricity is
required. In some cases 440V 3-phase (20 amp), 220 1-phase (20 amp)
or a combination of the two will be required within 150ft of the
area to be coated. If this might be a problem please let us know so
that we may take appropriate action.
On site access to water is necessary for
applications to be wet prepped by scrubbing and/or etching (not
including shotblasting or scarifying unless otherwise stated).
Site is to be free of equipment, materials, and
supplies PRIOR to crew arrival. Please allow a two foot “buffer”
around areas to be coated whenever possible to allow for over
cleaning. In the event objects are not moved or are unable to be
moved our crews have been instructed to coat up to and around these
The customer shall also be responsible for broom
cleaning prior to coating.
The owner is responsible to remove any paint over
spray, concrete spillage, or stains prior to coating. These may not
be completely removed during the preparation process unless
otherwise stated. In the case of clear coatings remember that the
finish will highlight and inconsistencies or irregularities.
Please notify Vanguard if area to be coated has
been exposed to standing water or is less than 28 days old prior to
coating so that we may do anything necessary to provide our coating
the best possible bond and ultimate coating lifespan. Please confirm
that all valves, pipes, tanks, roofs (yes, roofs) etc. are not
leaking to avoid damage to wet coating.
In some cases it may be necessary for the customer
to provide a storage area for floor treatment materials as they
arrive. In some cases this storage area must be suitable for the
storage area of flammable, corrosive and combustible materials. If
storage is required you will be notified prior to its arrival.
The customer is responsible to establish and
maintain safeguards as are necessary for the protection of its
employees, its equipment or personal property and the public on the
job site. Vanguard will protect and identify coated areas with
caution tape. Unfortunately many individuals choose to ignore this
identification and walk on soon to be or already coated floors,
which may affect bond to concrete, create unsightly foot-prints in
or around the floor, cause injury. Please speak with any individuals
that may be at or around the job site before or arrival as we are
not responsible for damage to the floor or persons for failure to
observe posted cautions.
Unless otherwise stated the customer must provide
a Dumpster for disposal of waste generated on the job site. In the
case of mechanical preparation such as shotblasting, scarification,
or grinding concrete dust will be generated. In the case of product
containers unless otherwise stated all products used by Vanguard are
non-hazardous when dried. In some cases it may be necessary to allow
for these materials to dry prior to placement in dumpsters. All
cleaners and detergents use by Vanguard are “sewer safe” and will be
sent down a sanitary sewer. If this is a problem please contact
Vanguard so that other arrangements may be made.
