Scope
of work
This work consists of furnishing all labor, materials, tools, equipment,
and service necessary to satisfactorily complete the rubber flooring
and/or rubber stair treads shown on drawings or in finish schedule. |
Performance
Requirements
Resistance to Dynamic or Rolling Loads Care must be taken to prevent
damage to rubber flooring by wheeled vehicles and furniture or appliances
with casters. To reduce rolling resistance and minimize risk of
cutting, indenting, or grooving the rubber flooring, the proper
wheels and casters should be selected to carry a load of not more
than 150 pounds per square inch (10.6kg per cm2). Since rollers,
casters, and wheels on furniture and appliances may
damage resilient flooring, any warranty as to their suitability
lies with the furniture or appliance manufacturer. |
Static
Loading
Floor protectors should be chosen so that stationary loads do not
exceed 150 pounds per square inch (10.6kg/cm2). At room temperature,
the rubber flooring shall bend around
a 3/4" (19 mm) mandrel without breaking, crazing, cracking,
or showing any change in color. |
Certifications
Rubber Stair Treads meet requirements of ADA.
Rubber Stair Treads meet Federal Specification RR- T -650e (Composition
A).
Vinyl Stair Treads meet Federal Specification RR- T -650e (Composition
B).
VI Series Stair Treads meet California Standard Code Title 24 for
the Visually Impaired.
None of the products contains ozone-depleting chemicals (ODC's)
nor are they produced using ODC-containing materials. |
Environmental
Conditions
The room and material temperature should be 70°F (21°C) 48 hours
prior to, during and after installation. (Temporary HVAC is not
acceptable. Systems should be fully functional prior to any resilient
flooring installation.) The sub-floors which are to receive rubber
flooring shall be smooth, clean, and dry and shall be inspected,
approved, and accepted as satisfactory by the sub-contractor for
resilient flooring before installing this material. (When rubber
flooring is to be
installed over a wood sub-floor treated with fire retardants or
a metal sub-floor, contact us for recommendations.)
For on-grade installations where there is a possibility of moisture
being present, it is recommended that The R.C.A. Rubber Company's
#5 Epoxy Flooring Adhesive be used.
Moisture transmission should not exceed three pounds per thousand
square feet per twenty-four hours. Where excessive moisture exists,
we do not recommend the installation of our Rubber Flooring products.
We do not recommend that our Sheet Rubber or Rubber 1ile Flooring
be installed in the following: below grade, commercial kitchens,
chemistry or biology laboratories, exterior installations or over
existing installations of floor coverings. |

| Sub-Floor
Preparation for Rubber Flooring and Stair Treads |
| General |
| Just
prior to the installation of the resilient flooring, the sub-floor
should be broom swept and damp mopped and allowed to dry. |
| New
Concrete Sub-Floors |
Concrete
should be troweled to a smooth, even surface and be aged for at
least 90 days. Expansion joints should be properly filled. Neutralize
the surface of the concrete. Use either 1 part Muriatic Acid and
9 parts water or 1 part white vinegar and 5 parts water to make
a good neutralizing agent. Solution should remain on floor for at
least one hour then flushed thoroughly with water. Allow to dry
thoroughly (minimum 48 hours at 70°F). Concrete should be sound,
hard and free from scale or other imperfections and thoroughly dry
when installation is made. CAUTION; cinder fill, vermiculite, pumice,
and other aggregates, which are hygroscopic in
nature, cause the concrete to be very slow drying. This type of
concrete will easily absorb excessive moisture from the atmosphere
and other sources. Any concrete curing compound must be completely
removed. |
| Wood
Sub-Floors |
A
solid core, exterior grade plywood with one side sanded is recommended.
Lauan, Particle Board, Chip Board or Hard Board should not be used
as underlayment. Be sure wood
sub-floor is thoroughly nailed or otherwise securely fastened to
the substrate. If the wood sub-floor is uneven, it should be sanded
smooth. The dust from the sanding operation should
be removed by vacuuming.
It is recommended that floor patching or leveling compounds are
to be non-gypsum based. |

| Installation
recommendations for Rubber Flooring and Stair Treads |
| General
Installation Considerations |
The
rubber flooring shall be installed in a neat and professional manner
with tight seams or joints, and with an adhesive appropriate for
the installation. For most installations, The R.C.A. Rubber Company's
#56 Latex Adhesive is appropriate. The R.C.A. Rubber Company's
#5 Epoxy Adhesive MUST be used for installations of Target®
Tile and Stair Treads.
It is recommended that all flooring materials be dry laid and inspected
to detect any possible abnormalities before beginning installation.
|
It
is recommended that flat wheels with no ridge(s) be used on rolling
equipment.
Immediately after installation, the rubber flooring shall be thoroughly
rolled in both directions with a 150 pound (68kg) sectional roller.
It may be necessary to weight the seam until
a suitable bond has been established.
The R.C.A. Rubber company's #5 Epoxy Flooring Adhesive MUST be used
in Hospital Operating Suites. |
| Flexi-Flo®
Sheet
Rubber Flooring Installations |
Overlap
edges of sheet rubber so that all seams can be double cut to assure
a better appearance. Underscribing is not an acceptable installation
method.
When flashing the rubber flooring up the wall to base height, a
rubber fillet strip as manufactured by The R.C.A. Rubber Company
shall be installed where the floor and wall meet,
properly adhered. The top edge of the flashed rubber shall be fitted
to a metal cap or other suitable trim. The flashed rubber shall
be securely adhered to the fillet strip and the wall. (Where specified
or indicated on the drawing, metal caps, end-stops and corners shall
be manufactured by the B&T Metals Company of Columbus, Ohio.) |
| Optional
Chemical Seam Bonding |
After
dry cutting and fitting the Flexi-Flor Sheet Rubber Flooring, a
4" to 6" (10cm to 15cm) wide band of The R.C.A. Rubber
Company's #5 Epoxy Flooring Adhesive is applied
at the seam and field cuts. At the same time, The R.C.A. Rubber
Company's #56 Latex Adhesive is spread in the field areas. The Flexi-Flor
should then be placed into the adhesive and rolled with a 150 pound
(68kg) roller. To assure proper bonding, a hand roller should be
used at the seams to force the adhesive into the seam and create
a chemical bond. Follow adhesive label directions. Clean up excess
adhesive immediately. It may be necessary to weight the seams until
a suitable bond has been established. |
| Stair
Tread Installation |
The
surface of the steps, risers, landings, and sub-floors should be
sound, clean, free of foreign matter and dry. Moisture transmission
should not exceed 3 pounds per thousand square feet per twenty-four
hours. Wooden steps shall be thoroughly nailed before installation
of treads. The surface of the concrete in metal pan-filled stairs
shall be troweled smooth with no ridges and level with the top of
the pan. The treads and risers shall be carefully fitted in a
neat and professional manner, securely bonded with the appropriate
adhesive. (#5 Epoxy Adhesive MUST be used on all Target stair treads.
Neoprene Contact Adhesive MUST be used on all Vinyl stair treads.
For most other tread installations, #56 Latex Adhesive is appropriate.)
The nose of the stair tread shall fit tightly against, and be securely
bonded to, the face of the stair riser or nosing. Open spaces at
the nosing between the step and the stair tread shall be filled
with The R.C.A. Rubber Company's #1 O Epoxy Stir Caulk. All stairs
and risers shall be
thoroughly rolled until a suitable bond has been established. (Abrasive
strip stair treads should be installed with a 1/16" (10mm)
gap at each end of the stair tread to prevent loosening of the abrasive
strip). |
