INSTALLATION
Limitations
Laytac 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
Laytac flooring 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 45.72cm (18 in.) of well-ventilated air space below
- Certain metals
- Radiant-heated subfloors with a maximum surface temperature of 29C (85F)
- The tiles will need to be the temperature of the room prior to installation
- Existing resilient flooring, laminates, and wood flooring that are clean, dry,
stripped of wax and even
Laytac flooring is UNSUITABLE for application over:
- Any floor that has excessive debris, dust particles, or sand
- Existing ceramic floors (existing ceramic floors must be either removed and the
subfloor re-leveled or the existing ceramic floor must be leveled to eliminate
unevenness of grout lines)
- Carpeting
- Rooms with excessive temperature swings (more than 25C degrees)
- 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 1441
kg/m (90 lbs per cu. ft.) or cellular concrete having a plastic (wet) density
less than 1602 kg/m (100 lbs per cu. ft.) [1506 kg/m (94 lbs per cu ft.) 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
Installation
Subfloor Preparation:
- 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, a cementitious, water-based leveling compound should be
used. Direct to earth concrete and stone sub-floors must incorporate an
effective damp proof membrane to ensure that they are sufficiently dry
- While it is not required, the use of a quality primer prior to installation
will assist with the initial adhesion of the tile to the subfloor
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 6mm (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
Moisture Test on Subfloor:
- Calcium Chloride (or Relative Humidity) Tests for moisture must be conducted. We recommend a guideline of a maximum acceptable moisture emission level of 5.0 lbs per 1000 sq ft. per 24 hours, according to the Calcium Chloride test...and 80% RH in the Relative Humidity Test. Bond Test should be conducted for compatibility with substrate. When testing for alkalinity, the allowable readings for the installation of Oasis flooring are 5 to 9 on the pH scale.
Temperature and Storage Conditions:
- Temperature shall be maintained at a minimum of 16 C (65F) and a maximum of 38
C (100 F) for 48 hours prior to installation. Ideal temperature should be the
room temperature during installation and 48 hours after completion. 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 or exposure to freezing conditions 48 hrs prior
to installation
Installation Procedure:
- Simply remove the release paper from the back of the product and push firmly
into place. It is recommended that a roller be used to ensure even pressure and
secure initial adhesion of Latyac to the subfloor
Adhesives (if used) Procedure:
- It is not necessary to install Latyac flooring with an adhesive. However, for
areas of excessive topical moisture, in shower rooms, in areas subject to
excessive heat or moisture, excessive sunlight, heavy rolling loads or high
traffic, or adjacent to plate glass windows, Latyac flooring may be installed
with an acrylic polymer-based premium vinyl-backed flooring adhesive
Warning
Do not sand, dry sweep, dry scrape, drill, saw, beadblast or mechanically chip
or pulverize existing resilient flooring, backing, lining felt, asphaltic "cut
back" adhesives or other adhesives. These products manufactured by other makers
may contain asbestos fibers and/or crystalline silica. Avoid creating dust.
Inhalation of such dust is a cancer and respiratory tract hazard.
After Installation:
- The floor is ready for traffic once installation is complete
