6. Protruding nails should be leveled or removed. Holdfast or screw nails
should be used.
7. Single sheets of wooden sub-floors should not exceed 16 square feet or 1.2
square meters.
8. Expansion space between wood panels should be .038" or 1 mm.
9. Dents, seams and holes may be leveled with the rubber tile epoxy adhesive
or cementituous leveling compound. After cure, the adhesive must be sanded
to roughen its smooth surface.
10. Plywood sub-floors should be screwed down or nailed with flooring ring
nails. Use a minimum of 1 fastener per 9 square inches of sub-floor.
Note: the use of cement board such as Hardie Backer is acceptable. Be sure to
smooth all points and dimples made by fasteners with a cementituous patching
compound.
III. Laying Tile
A. Sufficient light is essential. Lighting conditions must be bright enough to observe
color consistency, registration and seaming quality during dry fit inspection.
B. Dry fitting rubber tile is required. Dry fit an entire floor by sections, positioning
the tiles point to point. Tile will display a “small” E, number or logo in one corner
on the top surface. Position the tile so that the E’s, numbers or logos, are all in the
same position.
1. Line up the first row of rubber tile with a chalk line. Lay a second row again
point to point. Do not pressure-fit the joints in order to prevent peaking of
seams.
2. When the tiles have been dry-fitted, check the flooring for possible imperfections
or defects including trim, thickness or color. Replace any such tiles prior to
adhesion. Any defects in the tile, including color variation, registration,
squareness etc. must be reported before the tile is adhered or the installer
will be liable for replacement labor and material.
IV. Tile Adhesive Descriptions and Procedures
Only approved adhesives must be used for warranty to apply.
A. Adhesive Descriptions
1. BR 721™ Epoxy – Solvent Free. This is the standard rubber tile adhesive
where solid strength but a flexible bond is required for heavy duty foot and
vehicle traffic. Above, on or below grade concrete or wood sub-floors, this
adhesive has high water resistance to surface flooding.
