There are overlaps in recommended system applications;
however, select types of chemistries are generally used for specific
environments. Whether the system selection is dependent on exposure to harmful
liquids or excessive abrasion due to wear, the ultimate abuse the surface will
experience must be understood to ensure a successful installation.
The selection process begins after a thorough new assessment
is done and a full evaluation checklist is created of the potential abusive
agents (extreme chemical exposure, light-to-heavy duty wear, wheeled traffic
from rubber and / or steel wheel, floors exposed to extreme temperatures or
thermal cycling that can cause thermal shock. There may be several types of
polymeric industrial flooring systems available to match the job.
In general, system thickness, installation time, chemical
resistance, cost, thermal shock resistance, and life expectancy increase as one
moves from coatings, to slurries, to broadcast systems, to trowel applied
floors. Each of these installation methods use a variety of chemistries.
The properties that the chemistry controls are chemical resistance, adhesion,
mechanical properties such as tensile and compressive strength, weather-ability,
shrinkage, and speed of cure.
Sealers
- are generally classified and any concrete coating product that is less than 3
mils in thickness and designed to inhibit absorption of liquids into the
concrete. Hardeners are classified as a product that penetrates into the
concrete to create a more watertight surface and/or to strengthen the concrete.
Acrylic sealers are the most common type of sealer. They are very economical and
easy to install. These are often used as a curing compound. (See curing
compounds) more info on sealers
Coatings
- are an economical, thin-mil system providing chemical resistance, ease of
cleaning, and a non-dusting surface. Applications include areas exposed to
chemical splash or spill and light-to-moderate traffic. Because coatings are
typically 40 mils or less, they will not hide or mask surface imperfections
beyond he system thickness unless previously repaired. They will not provide
slope or pitch to drain, rather they follow the contour of the substrate.
Coatings withstand only light thermal shock. Many base chemistries are available
to choose from to meet specific chemical resistance.
Broadcasts
- are an economical flooring system using fine aggregate granules combined in a
resin matrix. Broadcasts provide good skid inhibition and chemical resistance.
Applications include areas experiencing light-to-moderate chemical, impact, and
traffic exposure. Full 1/8" to 3/16" broadcast systems can be used in many of
the applications where 1/4" mortar systems were previously specified. As is the
case with coatings, many base chemistries are available to choose from to meet
specific chemical resistance. Slurry Broadcast systems will mask minor surface
imperfections.
Thick-Mil
Troweled - systems employ a mortar material with aggregate
fillers in a resin matrix for maximum strength and protection. This approach
provides high impact resistance, level surface, easy maintenance, good skid
inhibition, and resistance to thermal shock, or chemicals. Mortar systems are
often used to re-pitch floors to provide slope to drain.
Thin Or
Thick-Mil Broadcast / Troweled - is a mortar-like system
with highly decorative aggregates combined in a resin matrix. Applications
include areas needing highly decorative surfaces and resistance to wear and
chemical attack.
