INSTALLATION INSTRUCTIONS
Tile Floors Over a Heated Wire Floor System
on a Concrete Slab Subfl oor
The following installation instructions are a recommendation, but
are not intended as a defi nitive project specifi cation. They are
presented in an attempt to be used with recommended installation
procedures, as published by the Tile Council of America and as
specifi ed by the American National Standards Institute (ANSI).
SUBFLOOR
1. All subfl oor work should be in accordance with the recommended
procedures as published by the Tile Council of North America
(TCNA) and the American National Standards Institute (ANSI).
2. Concrete subfl oor should be level, properly sloped and structurally
sound.
3. Inspect concrete subfl oor for any open cracks and fi ll with a high-
grade epoxy fi ller.
4. Remove any excess concrete lumps or residue that may interfere
with the installation of the CORK underlayment.
TESTING FOR MOISTURE
1. Test any concrete slab subfl oor in direct contact with the ground,
either above or below grade, for excessive moisture vapor
transmission prior to the installation of the Cork underlayment.
2. If excessive moisture is present in the subfl oor, normally
>5 lbs. per 1000 s/f in 24hrs as per ASTM Test # F1869-04
(Calcium Chloride Test), some form of moisture vapor-retarding
remediation must be installed to correct the problem. Consult the
project architect or fl ooring adhesive manufacturer for details.
CORK UNDERLAYMENT
1. Starting in one corner of the space to be covered, measure the
length of the space and cut a piece, or several pieces, of Cork
underlayment to fi t the length of the space to be covered.
2. Snap a chalk line on the fl oor along the edge of the material
farthest from the wall. Move the Cork material out of the way to
begin applying the adhesive.
3. Using a properly sized V-notched trowel (minimum 1/8”) apply
a Latex-Modifi ed Thin-Set Mortar compliant to ANSI Standard
118.4 in the area between the chalk line and the wall down the
entire length of the area to be covered.
4. Lay the Cork material into the bed of adhesive mortar applied,
butting the pieces tightly against each other. Trim the last piece
to length to fi t the space to be covered.
5. Snap another chalk line the width of the Cork sheets from the
edge of the previously laid sheets and repeat the process of
applying the adhesive and installing the sheets, starting with a ½
sheet on alternating rows to stagger the seams.
6. Proceed to cover the entire room, making sure the sheets
are tightly butted together, without gaps. Roll the fl oor in both
directions using a 50 to 100# fl oor roller.
7. After completion, the Cork material should cover the entire fl oor
area without gaps and be securely bonded with any joints tightly
butted. It is recommended that you wait 24hours for the mortar
to set before proceeding.
ELECTRICAL HEATING SYSTEM
1. It is important to read and follow the WarmlyYours Instructions
COMPLETELY with regard to the installation of and the connection
of the system to the Electrical System of the building.
CERAMIC TILE INSTALLATION
1. Follow the tile and setting material manufacturers recommended
instructions for the installation of the fi nished fl oor tile conforming
to ANSI A108.1 A, B, C and A108.5, depending on the method
of installation.
2. Direct bonded applications of tile should be done with a Latex
Modifi ed Thin-Set Mortar compliant to ANSI Standard 118.4.
Note: The use of plastic trowels is recommended by some
manufacturers, to avoid damaging any wires during the tile
setting process.
3. Perform another connectivity test prior to the installation of the
grout.
