ZAXXON Flooring should NOT be used in the following areas:

• Commercial kitchens and commercial food processing areas
• Heavy industrial and exterior areas
• Hospital operating rooms
• Where pointed spikes such as golf or track shoes will be used
• Where the floor will be subjected to unusually concentrated static or dynamic loads
• External/Outdoor locations or in unheated locations

ZAXXON is suitable for application over:

• Concrete, terrazzo, and other dry, structurally sound monolithic subfloors, which are suspended or on grade
• Suspended wood subfloor construction with approved wood underlayments, and a minimum of 18" of well-ventilated air space below
• Certain metals
• Radiant-heated subfloors with a maximum surface temperature of 85F (29°C). Please note that ZAXXON is suitable for use with underfloor heating,which should be switched off for 48 hours before and after installation.

ZAXXON is unsuitable for application over:

• Existing resilient floors that are not smooth and securely adhered to the subfloor. (In these cases, the existing resilient floor must be removed, and the subfloor re-leveled. Some older resilient floors and adhesives once made by other manufacturers can contain asbestos - in cases of doubt when removing existing tiles, contact the relevant local authority for advice on removal and disposal of flooring products containing asbestos). Instead of removal, covering the existing resilient floor with a 1 / 4" plywood may be an alternative
• Chipwood pressboard or other than "underlayment grade" particleboard
• Subfloors where excessive moisture or alkali is present
• On-grade or below-grade sleeper-constructed wood subfloors
• Lightweight aggregate concrete subfloors having a density of less than 90 lbs per cu. ft (1441 kg/m) or cellular concrete having a plastic (wet) density less than 100 lbs per cu. ft (1602 kg/m)[94 lbs per cu. ft (1506 kg/m) dry weight], or concrete having a compressive strength of less than 3500 psi (24 Mpa). Concrete slabs with heavy static and/or dynamic loads should have higher design strengths and densities calculated to accommodate such loads. Concrete curing agents, sealers, hardeners, or parting agents should be removed

Preparation:
Read these installation instructions, those on the adhesive, and the MSDS thoroughly prior to installation.

To ensure good quality appearance and adhesion of our products, the subfloor must be hard, smooth, clean, dry, and free from defects. Subfloors/underlayments must be free from paint, varnish, solvents, wax, oil, existing adhesive residue, or other foreign matter. The use of a suitable leveling compound in accordance with the manufacturer's instruction will ensure that no irregularities show through to the surface of the finished floor. For all installations, ZAXXON recommends the use of latex-modified Portland cement-based compounds or underlayments which have a minimum compressive strength of 3,500 psi for filling, smoothing or leveling subfloor imperfections. Direct to earth concrete and stone sub-floors must incorporate an effective damp proof membrane to ensure that they are sufficiently dry.

Concrete (new): Must be allowed to dry thoroughly since the new concrete can contain a high percentage of residual moisture. If it is impractical to wait until the base has fully dried, the use of a suitable surface damp-proof membrane is acceptable. Note that, once fully cured, this membrane must be primed before a water-based self-leveling compound is applied. The supplier of a leveling compound will advise on a suitable primer.

Concrete (old): must be cleaned of all paint, grease, wax and any other foreign matter. A suitable leveling compound should then be used to produce a smooth and level surface, with good bonding between concrete and leveling compound.

Terrazzo/Stone: worn or damaged areas must be repaired. The surface must be thoroughly cleaned and may require leveling using a suitable leveling compound.

Wood: must be overlaid with minimum 1/4" exterior grade plywood, which must be suitably secured. All joints must be filled with a suitable smoothing compound to ensure that a good quality surface is produced.

Temperature and Storage Conditions:
Temperature shall be maintained at a minimum of 65F (16°C) and a maximum of 100F (38°C) for 48 hours prior to installation, during installation and 48 hours after completion when using ZAXXON K-167 Vinyl Floor Tile Adhesive.
When using ZAXXON K-167 Vinyl Floor Tile Adhesive or other Epoxy Adhesives, the temperature shall be maintained at a minimum of 65 F (29 C) for 48 hours prior to and during installation and for 48 hours after completion.

A minimum temperature of 55F (13 C) shall be maintained thereafter. Tiles must be stored flat. Condition all flooring material and adhesives to room temperature at least 48 hours prior to starting installation. Protect all materials from direct flow of heat from hot-air registers, radiators, or other heating fixtures and appliances.

Installation:
Stir any liquid on the surface into the adhesive and then full spread the adhesive using recommended trowel.

For porous and non-porous substrates, follow manufacturer's recommendations for open time, working time, trowels, spread rate, clean up and how long to avoid traffic after installation.

After Installation:
Do not walk on tiles freshly installed for 5-6 hours. Clean away excessive adhesive before it is allowed to dry. It is preferable to protect the floor from heavy traffic for 24 hours after installation. Floors must not be washed for 48 hours.

Recommended Adhesives:
ZAXXON Flooring should be installed using ZAXXON K-167 Vinyl Floor Tile Adhesive full spread.
ZAXXON Flooring installed in areas subjected to direct sunlight or topical moisture, in shower rooms, in areas subject to excessive heat or moisture, heavy rolling loads or high traffic, or adjacent to plate glass windows must be installed with ZAXXON E-268 epoxy adhesive. Thoroughly read and follow the detailed in structions on the adhesive label.
