Expansion by Congoleum is a 15’ wide flexible floor that

features UltraTec construction. This construction

provides controlled stability and eliminates curl allowing

the flooring to be installed by the Your Choice Plus

Installation System which includes the fully adhered,

perimeter fastened and loose lay installation methods.

Depending on the method used, the floor can be

installed with UnderFlor AS01 adhesive or QuikStik Tape.

RECOMMENDED APPLICATIONS:

The best method for a particular job depends on the

subfloor conditions. For example, the fully adhered

method is recommended where the subfloor is smooth,

structurally sound and free of movement, in a variety of

applications including complex room layouts or where net

fitting or coving is required.

The perimeter fastening and loose lay methods provide

subfloor masking benefits to allow installation over a

greater variety of surfaces that might otherwise be

unsatisfactory

for a fully adhered application.

The loose lay method is recommended for room layouts

where trim can be installed around the entire perimeter.

The perimeter fastening method can be used for most

applications and it provides not only subfloor masking

benefits, but also provides the option to fit flooring net

where it is not desirable to install trim.

Installation Temperature

Congoleum residential sheet flooring is designed to be

installed in enclosed, heated areas only where HVAC has

been in operation for at least 7 days prior to installation

and thereafter.

For best results the sheet flooring should be installed at

the same temperature as the room(s) will be when

occupied or in service. The subfloor, all flooring material,

and adhesive must be conditioned at a constant

temperature between 65°F (18°C) and 85°F (29°C) for 48

hours before, during and 48 hours after installation.

Thereafter, maintain room temperature between 55°F

(13°C) and 100°F (38°C).

Handling and Storage

Roll all Congoleum sheet products face out, wrapped

tightly around a rigid core with a minimum 4” diameter

until ready for installation. Store and transport the roll on

a flat surface with continuous support in a clean, dry,

interior area where it is protected from the elements.

Ideal long-term storage temperatures range from 50°F

(10°C) to 70°F (21°C).

Avoid stacking other heavy rolls or objects on rolls that

can crush or distort them. Always handle rolls carefully to

avoid damage.

RECOMMENDED SUBFLOORS AND PREPARATION

Suitable Substrates

Congoleum sheet products are recommended for

installation over properly prepared suspended wood

floors and approved underlayments, concrete on all grade

levels, metal, terrazzo, ceramic and marble. The substrate

must be clean, dry, smooth, structurally sound, and free

of curing compounds, parting agents, old adhesive, paint,

varnish, oil, grease, wax, solvent and other foreign

material than can affect the flooring or interfere with the

adhesive bond.

Wood Floors must be double layer construction for fully

adhered installations, or single layer approved subfloor

panels for perimeter or loose lay installations, structurally

sound and free of movement with at least 18” (46 cm) of

well-ventilated air space below. Sand joints smooth and

set fasteners 1/32” (.8 mm) below the surface. Rough,

weathered or damaged subfloor panels must be sanded

smooth or covered with a suitable underlayment panel.

Fill underlayment joints wider than 1/32” (.8 mm).

Concrete Floors must be clean, dry and smooth. Level rough or uneven surfaces, cracks and control joints with a portland cement-based patching compound. Do not install flooring over expansion joints. Moisture vapor emissions must not exceed 3-lbs. /1,000 sq. ft. /24 hrs. when tested with the Anhydrous Calcium Chloride Test (ASTM F 1869) or 75% RH when tested in accordance with (ASTM F-2170) with a pH range between 6 and 9.

Note: The factory selvage edge may contain printed information that should be trimmed off. Prevent distortions from occurring during installation. Avoid folding, creasing, or kinking the flooring. Make sure the flooring is not bowed when installing around island cabinets, extending into alcoves or through doorways into adjacent rooms. Stretch a string or chalk line from one end of the sheet to the other, over a continuous grout line to make sure it's straight.

• Allow the flooring to relax and flatten. If necessary use a soft bristle push broom to remove any distortions or air pockets. If using a combination of QuikStik tape and staples, complete the taped areas first. Turn back one edge of the sheet and remove the release liner leaving 12" to 18" covered at the ends. This will allow the adjacent sides to be turned back easily. Lay the edge back into place and continue working around the room removing the release liner and pushing the flooring back into place.

Cut the seam with a sharp utility knife and steel straightedge. Hold the knife at a 90° angle from the floor and apply sufficient pressure to cut through both sheets in a single pass. Use caution to avoid cutting into the subfloor surface. Adhering the Seam Fully Adhered Floors Turn the seam edges back and apply AS01 adhesive over the entire dry zone. Adhesive can be applied with a 1/16" x 1/32" x 1/32" (1.6 mm x .8 mm x .
