When your floor arrives from Rosco…

Inspect the floor for any damage that may have occurred in shipping. Contact Rosco
immediately if the boxes or rolls show signs of mishandling. Be sure to note any damage on the deliv­ery driver’s B ill o f Lading. Onc e y ou ha ve determined the condition of your floor, allow the floor to w arm
to room temperature. This is essential in the winter months, as the floor has the potential of being
shipped in temperatures below freezing.

Preparing your subfloor…

Proper preparation of your sub floor is essential to the long-term health of your Rosco Dance Floor. All
screw heads, nails, and other hard edged protrusions should be removed or covered prior to the
installation of your Rosco Dance floor. These materials can damage your floor beyond repair and cause
injury to dancers. Fill cracks in the sub floor with appropriate filler and sand smooth.

Cutting the floor to fit the space…

If you plan to cut the floor, determine the size of the pieces before you unroll your floor. Traditionally
the floor runs the width of the studio or stage, but the seams may run perpendicular to the width of the
stage with no ill effects on the floor. Prior to cutting, unroll the floor on a flat
surface , pre fer ably y our stage or s tudio . Measure do wn one edge of the floor t o the desir ed length, mak e
a mark, (measure this distance twice), then measure down the other edge of the floor the same
distance. Using a straight edge long enough to meet the points you have measured, draw a line or snap
a line of chalk with a chalk line between the points. With a matte knife and a straight edge
carefully cut along the line you have marked. Repeat this procedure for each piece of floor.

Protecting your floor…

Minimize the amount of “street” dirt on your floor by placing carpet or mats inside any
doorways where there is street access. Do not drink, eat or smoke while on the floor. Avoid placing any
sharp edged item, scenery, chairs, tables or other equipment onto the floor as these items may gouge,
rip or damage the floor.

Any substanc e spilled or dropped on the floor should be removed immediately. Do not remove any spills
or stains with scouring powders or pads as they will remove the finish and permanently damage
the floor.

Rolling and storage of your floor…

Prior to remov al and s tor age s w eep the floor to r emo ve an y dirt or material that might damage the floor
when rolled. Remove the tape working parallel to the floor so as to minimize movement of the floor
before you roll it. Roll the floor on a solid core (using the core pr ovided or a 3” diameter PVC pipe) keep
the edges as straight as pos
creases and wrinkles. Tape the f
protectiv e covering, such as Visqene or polyethylene. Store y our Rosco floor correctly. Dance Floor and
Cabriole should be rolled, wrapped and hung on a floor cart. Adagio, Apprentice and Royale should be
rolled, wrapped and stood on end.

n PREPARING YOUR SUBSTRATE

WOOD SUBFLOORS:

ROSCO RECOMMENDS THE PERMANENT INSTALLATION OF FLOORING PRODUCTS ON PLYWOOD
SUBFL

OORS WITH A MINIMUM THICKNESS OF 1/2” (about 6.35mm) BY AN EXPERIENCED SHEET VINYL

CONTRACTOR / INSTALLER.

The plywood used must be of underlayment grade as specified in CSA Specification 0121. All plywood panels
must be solidly nailed in place. Spiral thread nails must be used. Rosco will not assume responsibility for any
improperly installed substrates. The flooring contractor should make sure that improperly installed panels be
replaced or made sound by additional nailing. All minor imperfections, damaged areas, and knotholes should be
filled and made flush, so as to provide a smooth surface. The wood subfloor must be dry, smooth, and free of
moisture, oil, dirt, greases and waxes.

Rosco does not approve the use of “particle board”, “flake board”, or “chip board” underlayment for use with
its floorings. Products presently available of this class vary widely in quality and performance with resilient
flooring. Certain “particle boards” are suitable for use as underlayment, but a guarantee to this effect should
be provided by the particle board manufacturer.

Any leveling or patching of wood subfloors must be done with a good grade of latex underlayment. Sand the
entire area using medium grade sandpaper to remove trowel marks and otherwise smooth the surface (latex
underlayment is not suitable for use in conjunction with certain adhesives).

Install the plywood with cross-joints staggered at least 16”(406 mm). Fasten to under-floor using angular
(ring-grooved) or screw nails that will penetrate 1-1/4”(31.75mm) into the subfloor. These fasteners are to be
spaced 24”(152.4mm) throughout the board and spaced 18”(76.2 mm) apart along the edges. Nail center of
board working out toward the edges to eliminate any irregularity. Do not fit the underlayment too snugly; leave
space between the boards equal to the thickness of a dime to allow for expansion in warmer temperatures.
Fasteners are to be driven flush with the surface or set no more than 1/16”(1.59mm) below. Lightly sand any
surface roughness, particularly at joints and around nails.

u Open Wood Joists:

Use 1/2”(15.87mm) plywood for 16”(406mm) or les s joist sp acing and 3/4”(19mm) plywood for joist spacing up
to 2’0”(609.6mm). Blocking is required under plywood along the edges perpendicular to the joists. Fasten the
plywood to the joists with angular (ring-grooved) or screw nails which will penetrate 1-1/4”(31.75 mm) into the
joist. Nail at 3”(76.2 mm) intervals along all edges and at 6”(152.4 mm) intervals over the joists.

NEW CONCRETE SUBFLOORS:

For newly poured concrete slabs on or below grade, the use of a permanent effective moisture barrier (such as
12 mil. polyethylene) should be installed beneath the slab. New concrete subfloors should be properly cured and

oughly dry before installation may be attempted. Depending on atmospheric conditions and/or possible

thor
excess water content, such subfloors will require at least six weeks drying time before they may be considered

eady for moisture tests.

r
Floors containing lightweight aggregate or excess water with steel or plastic pan construction may need a

longer drying time and should not be covered with resilient flooring until dry. Some lightweight concrete has
such low strength that it is unsuitable for vinyl flooring unless 1” (25.4mm) or more regular concrete is used as
a topping. This topping layer should be installed following recommendations of the Portland Cement
Association.

Since dampness must always be suspected, RMA moisture test units are available for use in checking subfloors
before solid vinyl floor installation. Consult with a floor installation professional for more information. IT IS THE

RESPONSIBILITY OF THE FLOORING CONTRACTOR TO DETERMINE WHETHER OR NOT THE CONCRETE IS
SUFFICIENTLY DRY FOR COVERING.

New concrete floors may be neutralized to remove excess alkali in those geographical areas where such
conditions exist. All adhesives are subject to serious deterioration resulting in bond failure in the presence of
alkaline conditions. One part muriatic acid and nine parts water make a satisfactory neutralizing solution.
DURING THIS PROCESS THE USE OF RUBBER GLOVES, APRON, BOOTS AND GOGGLES IS RECOMMENDED.
Flood the floor with the neutralizing solution and allow to remain at least one hour before rinsing off with clear
water. Be sure that ALL NEUTRALIZING SOLUTION IS REMOVED WITH RINSE WATER.

Allow concrete to dry thoroughly.
Concrete curing agents, parting compounds, surface hardeners and the like should not be used on the subfloor

unless the manufacturers of such agents, compounds and hardeners guarantee that these materials will not
adversely affect the bond of the adhesive to the concrete. If such materials have been used without the
manufacturer’s guarantee, such materials must be ground off before any tile installation. Such agents, in many
cases, form a surface film of oil, wax or resin which tends to obstruct the bond between the concrete and the
adhesive. Removal, if required, is extremely difficult. Surface grinding is found to be the most effective.

EXISTING CONCRETE SUBFLOORS:

For best results, old c oncr et e floor s should be pr epar ed t o con f orm as clos ely as possible t o ne w c oncre t e floors .
Cracks, expansion joints, uneven and rough areas require the application of good quality cement based
underlayment to level.

The subfloor must be firm and fr ee of moist ure , dust, s olvent , paint, w ax, oil, gr eas e, asphalt , sealing compounds ,
and other foreign substances. Paint should be removed by sanding the floor until clean. Use coarse No. 4 or No.
5 open grit sandpaper. A strong solution of trisodium phosphate or lye may be required in difficult cases.

RADIANT HEATED SUBFLOOR:

The requirements that apply to suspended, or on grade concrete floor, should be observed with radiant heating
systems. Rosco Floors may be installed provided the maximum temperature of the surface of the floor does not
exceed 89º Fahrenheit (32º Centigrade) under any condition of use. If radiant heated floors have been allowed
to cool after installation, it is possible that moisture will be absorbed in the concrete subfloor. It is, therefore,
recommended that the floor t
