3 EXECUTION

•  SITE VERIFICATION OF CONDITIONS

.1 Examine floor areas to be covered and report any deficiencies to the Contractor. Do not proceed with installation until substrates and conditions comply with manufacturer's requirements for installation.

.2 Ensure floor substrate is clean and dry by using test methods recommended by flooring manufacturer.

.3 Ensure building area and materials for flooring application is maintained at minimum 15 degrees C, maximum 30 degrees C and at maximum 65 % relative humidity for minimum 48 hours before installation, during installation and for minimum 72 hours after completion of work.

.4 Provide ventilation to installation area during installation and for minimum 72 hours after completion of work.

Spec Note: Select appropriate substrate preparation

3.2 WOOD FLOOR PREPARATION

.1 Ensure wood subfloor material is CDX exterior plywood installed smooth side up.

.2 Caulk all nail, staple or screw fasteners and seal with epoxy sealant.

.3 Acclimatize subfloor for minimum 48 hours before installation of flooring tile.

.4 Ensure subfloor is clean, dry and free of dust, dirt and any contaminants and previous floor finishes.

.5 Patch cracks, holes and rough or uneven areas with manufacturer's recommended cement based leveling compound.

•  CONCRETE FLOOR PREPARATION

.1 Ensure subfloor is smooth and level to a tolerance of 3 mm in 1.8 m.

.2 Ensure concrete floors have cured for minimum 6 weeks.

.3 Perform moisture test recommended by flooring manufacturer on concrete floor.

      .a Poly File Test: Tape a sheet of plastic over a section of the concrete floor. Wait for 72 hours. Check for moisture droplets under the plastic sheet.

      .b Calcium Chloride Test: Perform quantitative test, maximum 1.36 kg moisture emissions per 24 hours per 93 m2.

.4 Seal new concrete floors.

.5 Ensure existing concrete floors are clean, dry and smooth.

.6 Remove any wax, paint, varnish, adhesive or any other material that would prevent proper bonding of adhesive.

.7 Repair any low spots with a cementitous based latex patch mix.

.8 Seal concrete that is rough or porous.

•  APPLICATION: FLOORING

.1 Ensure back of rubber flooring has been sanded to remove mold release. (if required).

.2 Apply adhesive uniformly using recommended trowel and application rate. Ensure a minimum 85% transfer from the floor to backing of flooring.

.3 Do not spread more adhesive than can be covered by flooring before initial set takes place.

.4 Lay flooring in a point to point installation with [colour swirls orientated in the same direction] [with colour swirls orientated in alternating directions]. Lay out to produce a minimum number of seams. Border widths minimum 1/3 width of full material.

.5 Adjoin factory edge to factory edge of tiles. Install cut edge of tiles along walls or vertical surfaces.

.6 Ensure joints are tight. Eliminate joints opening up between tiles by taping tile corners together with masking tape.

.7 Lay tiles in small sections and roll with a 45 kg sectional roller within 15 minutes of laying to ensure proper adhesive contact.

.8 Cut tiles neatly around fixed objects, and to fit irregular and fill-in spaces using a sharp utility knife. Make repeated passes when cutting to ensure straight cuts.

.9 Continue flooring through areas to receive movable type partitions without interrupting floor pattern.

.10 Terminate flooring at centreline of door in openings where adjacent floor finish or colour is dissimilar.

.11 Install beveled transition edge strips at unprotected or exposed edges where flooring terminates.

.12 Promptly clean adhesive from top surface of tiles using a soft cloth soaked in denatured alcohol.

.13 Prevent traffic on flooring for minimum 24 hours after installation.

3.5 CLEANING AND MAINTENANCE

.1 Initial Cleaning:

       .1 Wait 48 hours after installation before proceeding with cleaning.

       .2 Sweep tiles to remove all loose dirt and debris.

       .3 Ensure petroleum based cleaners are not used.

       .4 If required to remove mold release:

•  Work in small areas of floor at a time

•  Apply a recommended floor finish stripper diluted with water using a mop. Leave mix on floor for 5 to 7 minutes.

•  Scrub wet floor using a rotary buffing machine equipped with a medium ‘Scotch Brite' pad.

•  Remove wet residue using a wet-dry vacuum

•  Mop rinse floor with clean water and repeat removal and drying method.

•  Repeat cleaning operations as required to remove any remaining mold release or sediment.
