3. All seamless floors
are
“manufactured” at
the jobsite, so any
detail or non-
standard
configuration of a
room can be coated
with a poured-in-
place flooring
system, yielding a
clean, monolithic
surface.
4. Seamless flooring is ideal for commercial, industrial, or institutional settings.
The partial list below indicates the range of seamless floor applications.
Any space where cleanliness, low maintenance, and high overall performance and
aesthetics are desired is an opportunity for a seamless flooring system.

• Laboratories
• Manufacturing Areas
• Medical Facilities
• Pharmaceutical Plants
• Research Facilities
• Airplane Hangar Floors
• Schools
• Shower, Locker, & Toilet Rooms
• Exterior/Interior Vehicle and Pedestrian Areas
5. No joints
• Non-porous
• Chemical and Stain resistant
• Resistant to Bacterial Growth
• High impact resistance
• High compressive strength
• Self-extinguishing

7. The seamless floor market segment has two broad-brush distinctions: decorative or
non-decorative.
Non-decorative seamless floors have a solid color look, with no speckled or mosaic
appearance. The binder and topcoat resin is usually one or more thin applications of
epoxy, urethane, polyaspartic, or methyl methacrylate (MMA) resin.

15. Decorative floors use a colored “filler,” usually either a vinyl flake or color-
coated quartz. The aggregates are finished with a clear resin (epoxy, etc.),
then a final top coat(s) is applied. The topcoat can be epoxy, urethane,
polyaspartic, or MMA. Water-based options can also be used. Typical system

are endless. Many custom patterns
and formulas can be achieved with
these systems.
Applications include:
•Lab floors
•Locker rooms
•Clean room environments
•Corridors
•Kitchens
•Retail spaces

•Numerous other applications
23. Some versions of seamless
flooring systems have soft base
coats and fillers that produce
cushioned floors that create an
ergonomic environment for the
user of the space.
Other benefits of this type of
seamless floor include chemical
resistance and improved
acoustic qualities.
For labs, hospitals,
pharmaceutical, and vet clinics,
the advent of soft, quiet floors
is an ever-growing market. For
such applications, a seamless
floor solution provides a
hygienic solution with no
unsightly seams or joints to
harbor dirt and bacteria.

29. When the needs of the space require an electro static dissipative system to eliminate
static discharge, a resinous floor with an ESD finish can be specified. An ESD system is
electrically conductive in the range of 1,000,000 to 1,000,000,000 ohms. The other
version of this system is categorized as a “Conductive” floor system, which provides
lower electrical resistance (i.e., greater conductivity) in the range of 25,000 to
1,000,000 ohms. Both ESD and Conductive finishes can be utilized with decorative and
non-decorative seamless floors, as well as epoxy terrazzo floors.
30. Common applications for
ESD/Conductive seamless
flooring systems include:
•Electronics Industry
• Manufacturing/Assem
bly
– Data Processing
– Repair
• Pharmaceutical
• Manufacturing
• Military/Avionics
• Chemical Processing
• Explosion Hazard Areas
• Plastics (Nuisance Static)
• Explosives
• Manufacturing
31. Thin-mil/high-build coating systems typically consist of a primer, a bodycoat, and a
topcoat(s). They are designed for light to medium duty traffic. The total thickness of a
thin-mil/high-build coating system ranges from 10 mils to 50+ mils, and may be
comprised of one or more of the following resins: Epoxy, urethane, polyaspartic, or
MMA.
32. Various thicknesses of cove base and termination strips can be
utilized. Sometimes, a sealant bead is used at the top of these
base details. Details are illustrated in the next slide.
34. These photos illustrate how the floor system may be carried up onto the wall,
creating a seamless surface. Terminations can be done with or without a strip,
depending on the adjacent floor finish. It is advisable to saw-cut and “key in” the
floor system into an unfinished space to negate any change in elevation from one
floor finish to the other.
35. This laboratory sample shows a concrete
crack running through the slab, into the
light gray filler epoxy, and stopping at
the yellow flexible epoxy membrane.
The fiberglass scrim, placed on top of
the membrane, provides additional
reinforcement against the movement. If
horizontal movement is less than 1/8″,
the cracks can be bridged using 32-40
mils of membrane.
Generally, this fluid-applied flexible
membrane is used for both slab-on-
grade and elevated slabs where crack
isolation and/or waterproofing is
needed. Note that a crack isolation
membrane is not also a moisture
mitigation system.
36. When installing a seamless
polymer floor it is required that
the concrete be tested for
moisture. If the test results are
high, a mitigation system must
first be applied to avoid any
potential for moisture-related
failure in the future.
Moisture mitigation systems are
applied directly on top of the
properly prepared concrete slab.
Some seamless floor systems
have incorporated a moisture
mitigation layer within the floor
system design, which is a more
economical way to deal with a
potential moisture issue.
65. Seamless floors have many different uses. To determine a suitable solution, one needs
to define the need of the space.
• Is it a decorative requirement? Or, is it truly a functional space first; aesthetics are secondary?
(e.g., a food processing plant or industrial facility)
• Is the space a public space, or is it only to be seen and walked on by the users of the facility?
• Is the area a “wet space,” requiring a slip-resistant seamless floor?
• Will people be standing on the floor for extended periods of time, requiring consideration of
an ergonomic cushioned system?
All of these are important considerations in the selection of the type, thickness, and appearance
of the seamless flooring system.
