10. OTHER SUBFLOOR REQUIREMENTS

a. Vinyl sheet goods, linoleum and resilient (VCT) tiles:

Old vinyl and linoleum tiles or sheet goods normally

do not need to be removed. Some older vinyl sheet

goods and tile contain asbestos. Should you choose

to remove these older ﬂoor coverings, consult a ﬂoor

covering retailer or the manufacturer of the vinyl ﬂoor

covering regarding the contents. Should it contain

asbestos special precautions for your safety must

be taken.

b. When Pergo ﬂooring is installed over vinyl, linoleum

sheet goods, over resilient tiles or ceramic tiles and

the subﬂoor is concrete, a vapor barrier is always

required.

c. Ceramic tiles and terrazzo: Old ceramic tiles normally

don’t need to be removed. Usually, Pergo ﬂooring

can be installed directly over ceramic tiles and ter-

razzo providing they are smooth, sound and dry.

These ﬂooring materials must be smooth and ﬂat to

within

⁄16" in a 10' radius. (See Subﬂoor

Requirements/General, section 7.)

d. Use Pergo Moisturbloc

together with Pergo

SilientStep

or Pergo Soundbloc Foam

or use the 2

in 1 product, Pergo SoftSeal

Foam/Film combina-

tion, or equivalent if the subﬂoor is concrete.

• If the Pergo Product being installed has an attached

foam underlayment then use only a vapor barrier

when installing over a concrete subﬂoor.

• When installing a Pergo Product with an attached

underlayment foam over a wood subﬂoor no other

additional underlayment is needed.

11. NEW C ONSTRUCTION REQUIREM ENTS: There are

several special considerations that must be evaluated

before installing Pergo ﬂooring in new construction.

a. As with all wood-based ﬂooring products, the installa-

tion should be scheduled as late in the building cycle

process as possible. This will prevent any unnecessary

damage from occurring as the result of other trades

involved with the construction process. Always protect

the ﬂoor if other trades will be walking on the ﬂoor

after installation.

b. The house/building must be closed and the climate

controls should be in operation for at least two weeks.

The temperature should be maintained between

65°F and 85°F during these two weeks and the relative

humidity should average between 30% and 90%.

c. Close attention must be paid to the condition of the

subﬂoor. (See sections 7 through 10 for your speciﬁc

subﬂoor requirements.)

d. Moisture in the wood or concrete subﬂoor, founda-

tion walls, basement, or crawl space must be checked

and veriﬁed to be in compliance with the subﬂoor

requirements. (See Job Site Evaluation, section 6—

exterior/interior moisture conditions and sections 7

through 10 for your speciﬁc subﬂoor requirements.)

e. Kitchen cabinets should be installed before the ﬂoor

is installed. However, cabinets may be installed after

the ﬂoor is in place providing the cabinets, island

cabinets, etc. are not ﬁxed/attached to the Pergo

ﬂoor. Island cabinets can be anchored to the sub-

ﬂoor. The holes for the anchoring bolts or screws must

⁄2" on center, larger than the diameter of the bolts

or screws—this allows for the

⁄4" expansion space

needed for a ﬂoating ﬂoor to move without being

obstructed by the fastener. Other cabinets must be

fastened to walls or to the subﬂoor as described for

island cabinets.

f. Speciﬁc areas of the expansion spaces, and only

speciﬁc areas where there is water exposure, such as

the expansion space in front of the kitchen sink, in

front of the dishwasher or around the dishwasher

space if the dishwasher has not been installed yet, in

the refrigerator space and around any water supply

line, in front of any exterior doors and sliding glass

doors must be ﬁlled with Pergo Sealant or a 100%

mildew-resistant silicone sealant that will remain ﬂexi-

ble. (Also see sections 12 through 14, for Kitchen,

Bathroom and Laundry Room Installations.)

12. BATHROOM INSTALLATIONS: Because the Pergo sur-

face

is resistant to water, Pergo laminate ﬂooring can be

installed in bathrooms. However, it is very important to

prevent water or moisture from getting under the ﬂoor.

Installation in bathrooms must be made in accordance

with the following instructions:

a. The expansion spaces, all expansion spaces,

between the Pergo ﬂooring and walls, the doorway

transition or other ﬁxed objects such as pipes for radi-

ators, sinks, water supply to water closet or toilet

ﬂanges MUST be sealed with Pergo Sealant or 100%

mildew-resistant silicone.

b. The space around the perimeter of the Pergo ﬂoor

must be

⁄4" wide and sealed prior to installing the wall

trim. The

⁄4" expansion space must be completely

ﬁlled with sealant to avoid water getting underneath

the ﬂoor.

c. When Pergo ﬂooring is installed in a bathroom and

an adjoining hall or room, a T-Molding must be

installed in the doorway between the rooms or hall-

way and the expansion space under the T-Molding

must be ﬁlled with the proper sealant. Place sealant

in the expansion space of any ﬂooring transition in

the doorway of a bathroom.

d. Pergo must not be installed in rooms with a ﬂoor drain.

e. Pergo must not be installed over any ﬂoor that has a

sump pump—i.e. should there be a bathroom at a

below grade level or on-grade concrete slab in the

home and a sump pump is located on that below-

grade level ﬂooring or on the on-grade level subﬂoor,

then Pergo ﬂooring cannot be installed anywhere on

that ﬂoor.

f. Standing water should not remain on the surface of

a Pergo ﬂoor. Standing water is deﬁned as water that

has set on the surface of the ﬂooring for longer than

30 minutes.
