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

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.

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.

•Use high CFM vacuum to pick up dust.

•Wait for floor to dry thoroughly before applying floor finishes, usually 24 hours.

•Apply only thin coats of floor finishes and use a microfiber finish mop.

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.

D. ECOguard Clear Coat Sealer Procedures

Description

ECOguard is a water-based, clear, polyurethane maintenance coat. ECOguard is formulated for interior

applications.

Tools / Materials Required

Safety Glasses

Latex or Rubber Gloves

21” paint tray or rectangular mop bucket for sealer

Applicator Trim Pads

Safety / utility knife

Trash bags

18” stir sticks

Drill

Rags

Microfiber Mop

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.
