Mannington W000736521 Installation & Assembly

GENERAL INFORMATION

These installation specifications are for ADURA®Rigid. All recommendations are based on the most recent available information. All instructions and recommendations must be followed for

satisfactory

installation. You may also visit

Mannington.com for recent updates.

• Although acclimation is not specifically required, best installation

practice recommends that the product be installed close to intended occupied service temperature, generally a target of 70° F (21°C), but at least between 55°F (13°C) and 100°F (38°C).

• ADURA®Rigid is recommended for three season rooms and

seasonal homes over concrete substrate. Installer must provide at least 5/8” (16mm) expansion.

• ADURA®Rigid is not recommended where the floor might

experience temperature extremes beyond -20°F (-29°C) or greater than 150° F (65°C). Occupied use temperature range is assumed to be between 55° (13°C) and 100° F (38°C).

• ADURA®Rigid can be installed up to 50’ x 50’ (15.2 m X 15.2 m) or

total of 2500 sq. ft. (232.3 sq m) with a ¼” (6.4mm) expansion. Larger areas must provide a 3/8” (16mm) expansion up to 100’ x 100’ (30.4 m X 30.4 m).

• Install ADURA®Rigid only after the jobsite

has

been cleaned and cleared of other trade apparatus that may damage a finished installation.

• Mix and install product from

several

different cartons to ach ieve

desi rable plank variation.

• All subfloor

underlayment patching must be done with a nonshrinking, water-resistant, high-quality Portland cement patching compound.

• Structural subfloor requirements must meet local building codes

as well as Mannington criteria. For concrete subfloors, conformance to ASTM F 710 and for panel underlayment, conformance to ASTM F 1482.

• ADURA®Rigid is designed to be installed as an angle/angle

installation only.

SUBFLOOR INFORMATION

• Careful and correct preparation of the subfloor is a major part of

satisfactory

installation. ADURA®Rigid is designed using a “floating floor” installation method. Although ADURA®Rigid will bridge minor floor imperfections and gaps, heavy

roughness

unevenness in

the subfloor may telegraph

through

the new floor

covering.

• All subfloors should be flat to within 3/16” (4.8 mm) in 10’ (3048

mm) and 1/32” (0.8 mm) in 12” (305 mm).

• Never install ADURA®Rigid products over residual asphalt-type

(cut

back) adhesive. Residual cut back adhesive should be completely

removed and covered with high quality latex underlayment.

• ADURA®Rigid has an underlayment pad. No additional pad is

recommended.

Wood Subfloors

• All wood floors must be suspended at least 18” (457.2 mm) above

the ground. It is important to provide adequate crossventilation. Cover the ground

surface

of a crawl space with a suitable vapor barrier. Wood subfloors directly on concrete or installed over sleeper construction are

not

satisfactory

for

installation.

• ADURA®Rigid can be installed over many wood substrates that are

not suitable for fully adhered products if they are smooth, flat, structurally sound and free

deflection – including particleboard, chipboard, flake board and OSB. Caution: Damage may occur on wood panel subfloors during construction. The suitability of these floors is the responsibility of the installer.

• If the

surface

of the wood subfloor is not smooth, a 1/4” (6.4mm) underlayment panel should be installed over the subfloor. Any panels selected

an underlayment must meet the following

criteria:

o Be dimensionally stable o

Have

a smooth, fully sanded face so the graining or texturing

will not show

through

o Be resistant to both static and impact

indentation

o Be free of any

surface

components that may

cause

staining

such

plastic fillers, marking

inks, sealers,

etc.

o Be of uniform density, porosity and thickness o

Have

a written warranty for suitability and performance from the panel manufacturer or have a history of proven performance

Concrete Subfloors

• Concrete subfloors must be dry, smooth, and free from dust,

solvent, paint,

wax, grease,

oil, asphalt sealing compounds and

other extraneous materials. The

surface

must be hard and dense

and free from powder or flaking.

• Surface of the slab should be flat to within 3/16” (4.8 mm) in 10’

(3048 mm) and 1/32” (0.8 mm) in 12” (305 mm).

• New concrete

slabs

must be thoroughly dry (at least six

weeks)

and

completely cured.

ADURA®Rigid Installation Guidelines

ADURA®Rigid

Installation Guidelines

• All concrete

slabs

must be checked for moisture before installing material. Details for moisture testing can be found on our website. The final responsibility for determining if the concrete is dry enough for installation of the flooring lies with the floor covering installer. ADURA®Rigid must never be installed where excessive

moisture

emissions

may exist. In accordance with ASTM F1869 moisture emission from subfloor cannot exceed 8 lbs MVER (moisture vapor emission rate) per

1,000

sq. ft. per 24 hours

as measured with the calcium chloride test or ASTM F 2170 In Situ Relative Humidity Test not to exceed 85%. Mannington will not assume

responsibility for floor covering failure due to hydrostatic

pressure

or excessive

moisture vapor emission. New concrete

slabs

must be thoroughly dry (at least six

weeks)

and completely cured. Although the planks are not susceptible to damage from moisture,

excessive

subfloor moisture can be a breeding ground for mold, mildew and fungus – all of which can contribute to an unhealthy indoor environment. The Limited Warranties do not cover issues arising from flooding, leaking plumbing or appliances, water entering through sliding

glass

doors, presence

of mold, discoloration from mold or fungi or similar conditions.

• Holes, grooves, expansion joints and other depressions must be

filled with a high quality cementitious patching & leveling compound, troweled smooth and feathered even with the surrounding surface.

• Concrete floors with a hydronic radiant heating

system

are

satisfactory,

provided the temperature of the floor does not

exceed 85

°F

at any point. Before installing the flooring, the

heating

system

should be turned on to eliminate residual

moistur

e. Mannington does not recommend heated floor mats for

ADURA®Rigid.

Recommended Work Practices for Removal of Resilient Floor Coverings

WARNING: Do not

sand,

dry

scrape,

bead blast or

mechanically chip or pulverize existing resilient flooring, backing, lining felt, asphaltic

“cutback”

adhesive or other

adhesive. These

products

may contain

asbestos

fibers and/or crystalline

silica.

Avoid

creating dust. Inhalation of

such

dust is a cancer and respiratory

tract

hazard.

Smoking by individuals exposed to

asbestos

fibers

greatly

increases

the risk of

serious

bodily harm. Unless positively certain that the product is a non-asbestos-containing material, you must presume it contains

asbestos. Regulations

may require

that

the

material be tested to determine

asbestos

content.

RFCI’s

Recommended Work

Practices

for

Removal

Resilient

Floor

Coverings are a defined

set of instructions addressed to the task

of removing all resilient floor covering

structures. These instructions should be consulted with each installation. The link can be found on our website. See mannington.com or go to rfci.com.

Existing Floor Coverings

• ADURA®Rigid can also be installed over most existing

hard–surface floor coverings provided that the existing floor is well bonded, and the

surface made

flat and smooth.

•

Ceramic tile unevenness should be made smooth by applying an

overlay

such as cementitious

patching or leveling

compound.

• Existing floors should not be heavily cushioned and not exceed

one layer in thickness.

• Do not install over carpet.

• Floor should be flat, smooth, dimensionally sound and free from

deflection.

INSTALLATION

• ADURA®Rigid is designed to be installed

as a “floating”

floor. Do

not

secure

the planks to the subfloor. Always

undercut

wood doorjambs. Check local building code for metal door jambs. If they cannot be cut, then proper expansion must be maintained around the door jamb. Do not install cabinets or kitchen

islands

on top of

ADURA®Rigid.

Use

care when installing wall moldings and transition strips to not fasten through the product. ADURA®Rigid is an angle/angle installation which provides superior joint strength.

Layout

• It is important to balance the layout of the plank format. Proper

planning and layout will prevent narrow plank widths at wall junctures. Determine layout to prevent having

less

than half a

plank width or very short length pieces.

• As with all plank products, lay the long dimension of the plank

parallel to the long dimension of the work area.

• Accurately

measure

the room to determine the centerline, adjust this established line to accommodate a balanced layout and then transpose this line to a comfortable width

away

from the starting wall; approximately 2’ (609.6 mm) to 3’ (914.4 mm) wide. Determine if the starter row will need to be cut. If the first row of planks does not need to be trimmed in width, it may be

necessary to cut off the unsupported tongue, so a clean, solid edge is toward the wall.

• Position the first plank so that both the head and side

seam groove are exposed. NOTE: The groove is the longer of the locking profile, approximately 3/16” (4.8 mm).

This

requires installing the

product from left to right in

the

room.

Occasionally,

it may be

necessary

to install backwards.

This

may be done by sliding the

ADURA®Rigid

Installation Guidelines

grooves under the tongues and working

them

right to left, but

this is more

dif

ficult.

• Install the second plank in the row by angling the end tongue into

the end groove of the first plank. Be careful not to bend the corner of

the

plank. It is important to know that all structures expand and contract, including hardwood and laminate product. An

expansion gap of approximately 1/4” (6.4 mm) from the wall is recommended. Then cut a plank to length to start the second row. Stagger the end seam at least 6” (152.4 mm) from the first plank.

• Install the first plank in the second row by inserting the long side

tongue into the groove of the plank in the first row.

This

is best done with the low angle of the plank. Do not install ADURA®Rigid planks flat.

• Install the second plank in the second row by inserting the short

end tongue tightly into the previously installed plank end groove. Align the plank so

the

long side tongue tip is positioned just over the groove lip of the plank in the first row. Working from the end seam,

with a low angle, slide

the

long tongue into the groove of the adjoining plank. Use of finesse and slight pressure is required to seat the tongue into the groove. You will feel the tongue lock into the groove.

• Work

across

the length of the room installing planks along the wall in the first row and then aligning the planks in the second row. It is critical

keep these two rows straight and

square, as

they are the

“foundation”

for the rest of the installation. Check

squareness

and

straightness

often.

• Cut the last plank in the first row to fit approximately 1/4” (6.4

mm) short of the end wall.

Planks

may be cut with a saw or guillotine type cutter such as Bullet Tools Mega Shear. Often the remainder of this plank may be used to start the third row.

• Continue installing

planks,

being certain to maintain a random

appearance and offset end

seams

by at least 6” (152.4 mm). Maintain a 1/4” (6.4 mm) expansion space at all fixed vertical surfaces.

Make sure all planks are fully engaged – if slight gapping

is noticed the gap can be tapped closed by using a

scrap

of flooring and a tapping block. It is always work practice to use a Mannington Laminate Tapping Block (Order Code TPBK80115513NB - single or case of 25) to lightly tap rows as you install to ensure they are fully engaged in the locking system.

• When fitting under door

casings, toe kick

etc. plank must be modified using a small block plane. Remove a thin layer from the tongue to allow tongue and groove to be flat fitted while keeping the integrity of the tongue and groove. After checking the fit, apply a thin bead of MSS 20 (Order Code: 832202) or MCS 42 (Order Code: 849832) seam sealer on the groove then slide planks together to seal the joint tight. Wipe any excess sealer off the surface. If

necessary,

a flat pull bar may be used to

assist

in adjoining the modified planks. When fitting around obstacles or into irregular spaces

, ADURA®RIGID

can be cut

easily

and cleanly

using a multi tool or jigsaw. It is

often

beneficial to make a

cardboard template of the area and transfer this pattern to the plank.

Finishing the

Job

• Protect all exposed edges of ADURA®Rigid by installing wall base

and/or ADURA matching moldings.

Use

caution to prevent the

fasteners

from securing

the

planks to the subfloor. Do not allow the floor to become pinched. Considerations for transitions should be made for substrate changes, room to room environment changes, complicated layouts and subfloor elevation. Please see insert information on full glue step (using V88 adhesive or urethane adhesive) and Flush mount Stairnose installation (using urethane adhesive). Caulk along tubs, toilet bowls, etc. using 100% silicone caulk.

• After 48 hours, damp mop to remove residual surface dirt. Follow

appropriate maintenance schedule using Mannington Ultraclean or quality rinse free cleaner.

REPAIRS

• ADURA®Rigid is tough and durable; however, if a plank becomes

damaged it can be replaced.

• If the damaged plank is along the perimeter of the room, the

easiest

technique is to just disconnect the planks until the

damaged plank is removed.

Replace

the material and

reassemble

the planks.

• If it is impractical to just disconnect and

reassemble

the flooring,

follow this procedure:

• Using a circular saw and or a multi-tool saw, cut out and remove

the center of the damaged piece, leaving approximately a 1” (25.4mm) strip attached to the surrounding material.

• Carefully cut back from the corners of the plank or tile to the

inside

edge.

•

Remove

the edges by wiggling the cut plank out from the

tongue and groove of the surrounding pieces.

•

Prepare

the replacement plank by removing the leading edge of the tongue profile on the long side and the end of the plank. Careful not to damage the decorative surface. Remove the bottom of the groove on the short end side by cutting on an angle to remove. Once the plank is prepared, install groove into tongue to test the fit. Once you check the fit is correct you are now ready to complete the install.

• Position the replacement piece by engaging the groove into

the tongue of the adjoining material.

“Hinge”

the prepar

replacement plank into

position.

• Slightly lift prepared side of plank and apply a thin application

of M S S 20 (Order Code: 832202) or MCS 42 (Order Code:

ADURA®Rigid

Installation Guidelines

849832)

onto the three exposed seams and carefully position

plank into place,

wipe

excess

from surface.

• Use

a hand roller to

assist

in aligning the edges into

position.

• Weight the replaced plank for at least 15 minutes until the

sealer secures

the material.

CAUTIONS

AND MISCELLANEOUS

• Furniture should be moved onto the newly installed floor using an

appliance hand truck over hardboard runways.

•

Heavy

furniture should be equipped with suitable non-staining,

wide-bearing

casters

or protectors. Non-staining felt protectors are recommended for table and chair legs to help prevent scratching.

• Like with all floor coverings, it is best to protect ADURA®Rigid

installation

from exposure to direct sunlight. A

combination

of heat and sunlight can cause most home furnishings t o fade and discolor. Avoid exposure to direct sunlight for

prolonged periods. During peak sunlight hours, the use of blinds or drapes is

recommended.

• Oil or petroleum-based products can result in

surface

staining. Do not track

asphalt-driveway sealer

or automobile-oil drips onto the

ADURA®Rigid.

• Use rugs or mats labeled

“non-staining” that provide a

manufacturer warranty.
