I. JOB SITE CONDITIONS
A. Installation should not begin until after all other trades are finished in the area. If the job
requires other trades to work in the area after the installation of the floor, the flooring should
be protected with an appropriate cover.
B. Areas to receive flooring should be weather tight and maintained at a minimum uniform
temperature of 65˚ F (18˚ C) for 48 hours prior to, during, and after installation.
II. SUBFLOORS
ECOfit Plus rolls may be installed over concrete, approved Portland based self-leveling materials,
and wood.
Note: Gypsum based patching and leveling compounds are not acceptable.
A. Wood Subfloors: Wood subfloors should be double construction with a minimum thickness of
1”. The floor must be rigid, free from movement, and have at least 18” of well-ventilated air
space below.
B. Underlayments: The preferred underlayment panel is APA underlayment grade plywood,
minimum thickness of 1/4”, with a fully sanded face.
Note: Particle board, chip board, Masonite, and lauan are not suitable underlayments.
C. Concrete Floors: Concrete shall have a minimum compressive strength of 3000 psi. It must be
fully cured and permanently dry.
III. SUBFLOOR REQUIREMENTS AND PREPARATION
A. Subfloor shall be dry, clean, smooth, level, and structurally sound. It should be free of dust,
solvent, paint, wax, oil, grease, asphalt, sealers, curing and hardening compounds, alkaline
salts, old adhesive residue, and other extraneous materials, according to ASTM F710.
B. Subfloor should be smooth to prevent irregularities, roughness, or other defects from
telegraphing through the new flooring. The surface should be flat to the equivalent of 3/16”
(4.8 mm) in 10 feet (3.0 m).
C. Mechanically remove all traces of old adhesives, paint, or other debris by scraping, sanding, or
scarifying the substrate. Do not use solvents. All high spots shall be ground level and low spots
filled with an approved Portland based patching compound.
D. All saw cuts (control joints), cracks, indentations, and other non-moving joints in the concrete
must be filled with an approved Portland based patching compound.
E. Expansion joints in the concrete are designed to allow for expansion and contraction of the
concrete. If a floor covering is installed over an expansion joint, it more than likely will fail in
that area. Expansion joint covers designed for resilient floor coverings should be used.
F. Always allow patching materials to dry thoroughly and install according to the manufacturer’s
instructions. Excessive moisture in patching material may cause bonding problems or a
bubbling reaction with the E-Grip III™ adhesive.

HAZARDS
SILICA WARNING: Concrete, floor patching compounds, toppings, and leveling compounds can contain
free crystalline silica. Respirable crystalline silica (particles 1–10 micrometers) can be produced by
cutting, sawing, grinding, or drilling. Respirable silica is classified by OSHA as an IA carcinogen and is
known to cause silicosis and other respiratory diseases. Avoid actions that cause dust to become
airborne. Use local or general ventilation or protective equipment to reduce exposure below applicable
exposure limits.
ASBESTOS WARNING: Resilient flooring, backing, lining felt, paint or asphaltic “cutback” adhesives can
contain asbestos fibers. Avoid actions that cause dust to become airborne. Do not sand, dry sweep, dry
scrape, drill, saw, beadblast or mechanically chip or pulverize. Regulations may require that the material
be tested to determine asbestos content. Consult the documents titled Recommended Work Practices
for Removal of Existing Resilient Floor Coverings, available from the Resilient Floor Covering Institute.
LEAD WARNING: Certain paints can contain lead. Exposure to excessive amounts of lead dust presents a
health hazard. Refer to applicable federal, state, and local laws and the publication Lead Based Paint:
Guidelines for Hazard Identification and Abatement in Public and Indian Housing, available from the
United States Department of Housing and Urban Development.
G. Moisture must be measured using the RH Relative Humidity test method per ASTM F2170
standard. Moisture content should not exceed 85% RH. If the levels exceed the limitations, the
installation should not proceed until the situation has been corrected.
H. In the event that a moisture mitigation system is required, it must conform to the ASTM F3010
Standard Practice for Two-Component Resin Based Membrane Forming Moisture Mitigation
Systems for use Under Resilient Floor Coverings.
I. It is essential that pH tests be taken on all concrete floors. If the pH is greater than 9, it must be
neutralized prior to beginning the installation.
J. Adhesive bond tests should be conducted in several locations throughout the area. Glue down
3´ x 3´ test pieces of the flooring with the recommended adhesive and trowel. Allow to set for
72 hours before attempting to remove. A sufficient amount of force should be required to
remove the flooring and, when removed, there should be adhesive residue on the subfloor and
on the back of the test pieces.
IV. MATERIAL STORAGE AND HANDLING
A. Material should be delivered to the job site in its original unopened packaging with all labels
intact.
B. Roll material should always be stored lying down. Storing rubber on end will curl the edges,
resulting in permanent memory of the material. Do not store rolls higher than 4 rolls or for
more than 6 months. Material should only be stored on a clean, dry, smooth surface.
C. All edges with memory curl should be straight cut before installation. In some instances it may
be necessary to weigh down the seam until adhesive develops a firm set.
D. Inspect all material for visual defects prior to beginning the installation. No labor claim will be
honored on material installed with visual defects. Verify the material delivered is the correct
style, color, and amount. Any discrepancies must be reported immediately before beginning
installation.

ECOfit & ECOfit Plus Rolls Technical Manual
www.ecorecommercial.com 5
E. The material and adhesive must be acclimated at room temperature for a minimum of 48 hours
before starting installation.
V. INSTALLATION PREP
A. Rolls must be unrolled and installed in the same direction (Directional arrows are stamped on
bottom of the rolls; see Figure 1.) Rolls are labeled with batch numbers and roll numbers. Do
not mix batch numbers together and install all rolls in consecutive order. Laying rolls in the
opposite direction and out of sequence can cause color variations between the rolls.
Figure 1
B. Note: Custom roll lengths eliminate the possibility of the rolls being manufactured and
numbered in the customer’s desired installation sequence, and Ecore cannot be responsible for
any resulting shading issues.
C. Roll material is stretched slightly when it is rolled at the factory. Unroll all rolls and allow to
relax for a minimum of two hours before gluing or cutting material. Shaking the material once
unrolled can help it to relax.
D. Snap a chalk line where the first seam will be located. Straight cut the edge of the first piece if
required. Align the first roll factory edge to the chalk line.
E. Straight edge the second lineal drop if the first lineal drop is not long enough to span the entire
length or width of the room. If end or head seams are necessary, they should be staggered on
the floor and overlapped approximately 3-6”.
F. Position second row with no more than 1/8” overlap over the first roll at the seam (see Figure
2). After adhesive is applied to the substrate, the material will be worked back to eliminate the
overlap. This procedure will leave tight seams and eliminate any gaps. Care should be taken to
not over compress the seams. Over compressed seams will cause peaking.
Figure 2
G. Repeat for each consecutive roll to be installed that day.

ECOfit & ECOfit Plus Rolls Technical Manual

VI. INSTALLATION
A. After all above procedures are performed, begin application of the adhesive. Apply E-Grip III to
the substrate using a 1/16” square notched trowel.
B. Fold the first drop lengthwise (half the width of the roll).
C. Spread adhesive, taking care not to spread more E-Grip III than can be covered by flooring and
rolled within 30 minutes. The open time of the adhesive is 30 - 40 minutes at 70°F and 50%
relative humidity.
D. NOTE: Temperature and humidity affect the open time of the adhesive. Temperatures above
70°F and/or relative humidity above 50% will cause the adhesive to set up more quickly.
Temperatures below 70°F and/or relative humidity above 50% will cause the adhesive to set up
more slowly. The installer should monitor the on-site conditions and adjust the open time
accordingly.
E. Fold over second half of first roll and half of second sheet. Spread adhesive. At seam area
spread adhesive at 90 degrees to seam to eliminate excessive adhesive oozing up at seam. Roll
material.
F. Carefully lay the material into the wet adhesive. DO NOT let the material drop because this will
cause air to be trapped beneath the flooring.
G. Immediately roll the floor with a 75–100 lb. roller to ensure proper adhesive transfer. Overlap
each pass of the roller by 50% of the previous pass to ensure the floor is properly rolled. Roll
the width first and then the length. Roll again within the first 60 minutes. It may be necessary
to weigh down the seams until the adhesive develops a firm set.
H. Continue the process for each consecutive drop. Work at a pace so that you are always folding
material back into wet adhesive.
I. Do not allow E-Grip III to cure on your hands or the flooring. We strongly suggest wearing
gloves when using E-Grip III.
J. Immediately wipe off excess adhesive from floor with a rag dampened with mineral spirits!
Cured adhesive is very difficult to remove. Then wipe off the mineral spirits with a rag damp
with water.
NOTE: Use mineral spirits sparingly. Saturating the rubber with mineral spirits may cause the
adhesive to be pushed too deeply into the pores of the rubber.
K. Hand roll all seams after the entire floor has been rolled. If some seams are gapping, hold them
together temporarily with blue painter’s tape. Do not use duct tape as it may leave a residue on
the floor. Remove tape after adhesive has developed a firm set (approximately 2-3 hours).
Ecore will not be responsible for residue left behind from tape of any kind.
L. Keep foot traffic off the floor for a minimum of 24 hours. Floor should be kept free from rolling
loads for a minimum of 48-72 hours. Foot traffic and rolling loads can cause permanent
indentations or bond failure in the uncured adhesive.

Important Information for the Specifier
Ecore recommends our Environmentally Friendly Maintenance Products and Procedures for ECOfit.
Proper protection and maintenance of ECOfit post-installation should be specified by the
architect/designer. ECOfit products should not be subject to construction debris and potential damage
caused from heavy duty construction activities.
FLOOR PROTECTION
The specifier should include specification details to protect the floor post-installation and until job
construction is complete, such as covering the entire floor with paper or another floor covering device
(plastic, plywood, etc.) until construction is completed and thorough cleaning and maintenance can be
implemented.
ASSIGNMENT OF CLEANING AND MAINTENANCE
The specifier should determine and assign the responsibility for the initial cleaning and finishing. This
responsibility should be specifically assigned to the flooring contractor, general contractor, maintenance
contractor, or owner.

Maintenance
Cleaning Procedures – ECOfit & ECOfit Plus Coated with ECOguard
A. Initial Cleaning
NOTE: Adhesive should have 24 hours minimum to cure before cleaning the floor.
1. Remove all surface soil, debris, sand, and grit by sweeping or vacuuming.
2. Scrub floor with Ecore’s recommended E-Cleaner, using a buffer or auto scrubber with tool /
pad from table above. We recommend a 175 RPM buffer or auto scrubber. If soil is minimal, a
microfiber mop may be used.
3. Pick up remaining residue with a wet vac and damp mop floor. Allow floor to thoroughly dry.
B. Daily/Weekly Cleaning
1. Remove all surface soil, debris, sand, and grit by sweeping or vacuuming.
2. Damp mop or scrub floor using Ecore’s recommended E-Cleaner or equivalent with tool / pad
from table above.
3. Clean remaining residue from floor with a wet vac and damp mop floor. Allow floor to dry
thoroughly.
C. Heavy Soil Cleaning
1. Remove all surface soil, debris, sand, and grit by sweeping or vacuuming.
2. Scrub floor using ECORE’s recommended E-Cleaner with tool / pad from table above. Follow
“Dilution" above.
3. Pick up remaining residue with a wet vac and damp mop floor. Allow floor to dry thoroughly.
Note: If area is too small for a buffer or auto scrubber, a nylon deck brush may be used to remove
scuff marks or heavy soil. Brush should be approximately 22 gauge.
CAUTION – A “standard” black pad should be the most aggressive pad used. Ahigh productivity black
pad such as 3M’s 7300 series will act as a sander and damage the surface of the rubber. Ecore assumes
no liability in the event of damage to the rubber in the removal process. ECOguard is considered a
permanent sealer and not intended to be stripped from the rubber as a standard procedure. This
procedure is for restorative maintenance purposes only.

Surface Preparation
•An improperly prepared surface can act as a bond breaker and result in a project failure. It is
important to remove all dirt, grease, wax, oil, paint or other contaminants before applying the
ECOguard. ECOguard can be applied over the existing factory applied finish after all construction
debris and soil have been removed from the surface.
Precautionary Measures
•Allow ECOguard to cure for 24 hours before introducing foot traffic.
•Allow ECOguard to cure for 48 hours before cleaning, rolling chairs or dollies.
•If traffic and/or rolling loads need to be introduced earlier than listed above, the surface must
be protected from damage.
•Remove ECOguard spills and drips immediately from other surfaces before dry.
•Do not re-use microfiber pads after applying ECOguard.
•Seal floor in one step rather than in sections for best results.

ECOfit & ECOfit Plus Rolls Technical Manual
www.ecorecommercial.com 10
•If sealer dries on microfiber pad, replace with new microfiber pad.
•Sealer will obtain full strength in 5-7 days. Care should be taken during the first 5-7 days to
prevent damage to the coating. Extra coats will extend the curing cycle.
•String mops or other unapproved applicators may result in a poor application of the sealer and
complete removal may be required.
•Work from one side of the room to the other using a scrubbing motion with microfiber mop
keeping a wet edge.
Application Methods
1. Application of ECOguard Over Uncoated ECOsurfaces
2. Application of ECOguard Over Existing ECOguard
3. Removal / Stripping of ECOguard Sealer
1. Application Of ECOguard Over Uncoated ECOsurfaces
•IMPORTANT! Stir the ECOguard thoroughly for 3-5 minutes or until all sediment at bottom
of pail is mixed up into solution before application to ensure consistent sheen
•Safety glasses should be worn when mixing, pouring or applying ECOguard.
•Apply first coating of ECOguard to the rubber surface using Ecore’s recommended
Microfiber Mop. An applicator trim pad may be used for areas around the perimeter.
Additional one to two coats are recommended and an ample amount of time is required
between coats. Allow each coat to dry thoroughly to touch before applying the next coat,
about 2 - 4 hours.
•Over unfinished rubber the coverage rate is approximately 400-500 sq ft per gallon. Second
and Third coat coverage approximately 600-800 sq ft per gallon.
•Apply ECOguard when surface temperature is 65 degrees Fahrenheit or higher and
maintained for 72 hours before and after installation.
•Wear rubber or latex gloves when applying the ECOguard. Sealer will not harm the skin but
is difficult to remove once it dries. Wash hands immediately after contact with ECOguard
with soap and water.
•Allow ECOguard to cure for 48 hours before cleaning the surface.
2. Application Of ECOguard Over Existing ECOguard
•IMPORTANT! Stir the ECOguard for 3-5 minutes or until all sediment at bottom of pail is mixed
up into solution before application to ensure consistent sheen.
•Factory coated product should not require additional field coats. Should an additional coat be
requested, one should suffice.
•Prepare surface and remove all dirt, grease, wax, oil, paint, construction debris or other
contaminants before re-applying the ECOguard. Clean the surface thoroughly with a buffer or
auto scrubber using a 3M 5100 Red or equivalent pad. Keep in mind that these pads will slightly
abrade the finish and continued use will remove the sealer. Slightly abrade the finish creates an
acceptable surface on which to apply the new finish coat.
•Safety glasses should be worn when mixing, pouring or applying ECOguard.
•Wear rubber or latex gloves when applying the ECOguard. Sealer will not harm the skin, but is
difficult to remove once it dries. Wash hands immediately after contact with ECOguard with
soap and water.

ECOfit & ECOfit Plus Rolls Technical Manual
www.ecorecommercial.com 11
•Apply ECOguard when surface temperature is 65 degrees Fahrenheit or higher and maintained
for 72 hours before and after installation.
•Apply one coat of ECOguard using using a Microfiber mop and trim pad as desired.
•Additional coats are acceptable. Allow each coat to dry thoroughly before applying the next
coat, about 2-4 hours.
•Coverage rate is approximately 600-800 sq. ft. per gallon over previously coated surfaces.
•Allow ECOguard to cure for 48 hours before cleaning the surface.
3. Removal / Stripping ECOguard Sealer
•ECOguard is difficult to completely remove from the surface of the rubber and may take several
attempts. ECOguard is removed by abrasion using an approved stripping pad. Anything used to
chemically remove the sealer will jeopardize the integrity of the rubber.
•To remove, use E-Strip 32 oz. per gallon water and a buffer fitted with a 3M 7200 Black or 7200
Brown or equivalent stripping pad.
•Apply a liberal amount of diluted stripper to floor and work buffer from one side to the other
until sealer is removed. Successfully removing the sealer may require several passes with the
buffer or auto scrubber.
•CAUTION –DO NOT USE a high performance black pad such as 3M’s 7300 series. It will act as a
sander and will damage the surface of the rubber. Ecore assumes no liability in the event of
damage to the rubber in the removal process. ECOguard is considered a permanent sealer and
not intended to be stripped from the rubber as a standard procedure. This procedure is for
restorative maintenance purposes only. To re-apply ECOguard please follow step 1.
