flooring is any monolithic, poured in place, resin
based floor system. The intent and purpose of a seamless
floor system is to encapsulate an area so that no contamination
can get underneath, between, or past the floor’s
surface. There are a multitude of finishes that can
be incorporated into a seamless floor system with various
The most commonly used seamless floors will typically incorporate epoxy and
urethane resins in conjunction with quartz or silica aggregates, decorative
flakes, aluminum oxide, or other specialty aggregate materials which can increase
wear and performance. The type of finish incorporated will be chosen based
on the use expected for the facility. Factors such as slip resistance, chemical
resistance, compressive strength, and aesthetic properties of the finished
system will all contribute to the product selection process.
Seamless floors have specific requirements that must be met for a successful
installation. As with all adhered floors, the concrete substrate must be tested
for moisture. Compliance with moisture limitations should always precede surface
preparation of the concrete.
Since polymer based products have a set or tack time in which they remain open
or “sticky”, it is important to have the building enclosed and
prevent any traffic on the surface while curing. Open doors can allow dirt
and debris to become trapped into the product thus affecting the surface finish.
Some products may contain solvents or other VOC’s (Volatile Organic Compounds)
which may require respiratory protection for anyone in close proximity to the
application. Always obtain and post the Manufacturers Safety and Data Sheets
(MSDS) on-site in a conspicuous location.
Each product has its own specific guidelines for installation. Always follow
the manufacturers written instructions and consult the technical department
if questions arise. Seamless floors require the installation to be completed
in a single phase to achieve the desired finish. Therefore, it is necessary
to have a complete understanding of what is required prior to commencing work.
Patching can be troublesome, problematic, ineffective, as well as unsightly.
After moisture testing is performed and compliance requirements are met, most
systems require mechanical surface preparation prior to flooring installation.
Surface preparation insures that the substrate is sound, free of bond breaking
contaminants, and in an open and porous condition that will allow the seamless
floor system to achieve good surface adhesion. Most products are squeegee and
back-rolled or brushed.
All floor systems have specific requirements for successful installation. It
is important to verify that the product manufacturer’s written guidelines
govern the installation process. Adherence to instructions is critical for
maintaining the manufacturers’ warranty; neglecting them will almost
certainly void the warranty. Proper product selection based on end use, appropriate
scheduling with other trades, testing and compliance to product moisture requirements,
and installation per industry Best Practice methods are the keys to a quality
Seamless floors offer an easily cleaned and sanitary surface that reduces the
build up or deposit of soil generally associated with other flooring materials.
However, to achieve a monolithic installation over large areas it is necessary
to complete the installation in a single phase. This can pose challenges to
Contractors who have to remove most, if not all, sub-contractors for the duration
of the product installation and subsequent cure time. Proper coordination is
critical to maintaining time schedules as well as insuring the best possible
Regular maintenance is vital to the long term welfare of all floors. There
is no surface available that remains in optimum condition without regular cleaning
and maintenance. The floor is subjected to the most abuse in any normal business.
Keeping the floor in good condition takes a little forethought and consistent
effort. The first key to maintaining floors is preventing as much soil, debris,
and potential damaging agents from being introduced to the environment in the
first place. Interior and exterior walk-off mats can minimize the amount of
sand, water, and foreign matter that are tracked onto the floor. Limiting contaminants
will simplify the maintenance process.
Since most seamless floors are installed inside, cleaning methods generally
incorporate floor scrubbers, steam cleaners, wet vacuums, squeegees and mops
to perform daily floor maintenance. The type of cleaning equipment and chemicals
should be specified by the seamless flooring manufacturer.
