Part 3EXECUTION

3.1PREPARATION

.1Concrete floor slab must be smooth and level and be within tolerance of + 3 mm in 3 m radius. Remove ridges and bumps. Fill low spots, cracks, joints, holes and other defects with an approved filler. Remove any other contaminants such as grease, paint, dust, solvents or rust.

.2Moisture vapour emission content of the concrete floor slab shall not exceed 3 lbs/100ft2 (1.46 kg/100m2) per 24 hours when using the calcium chloride test method moisture vapour emission content prior to safety sheet flooring installation in new construction.Any corrective measures are the responsibility of the contractor. In the case of existing facilities where the safety sheet flooring is being replaced, the flooring supplier is to provide a flooring system suitable for the existing moisture vapour emission content as determined by the flooring supplier during the tender period.

.3Remove or treat old adhesives to prevent residual, old flooring adhesives from bleeding through to new flooring and/or interfering with the bonding of new adhesives.

.4Seal concrete slab or plywood sub-floor to safety flooring manufacturer's printed instructions.

3.2APPLICATION: FLOORING

.1Provide a high ventilation rate, with maximum outside air, during installation, and for 48 to 72 hours after installation. If possible, vent directly to the outside. Do not let contaminated air recirculate through a district or whole building air distribution system. Upon completion of work, maintain ventilation at maximum capacity until building occupation.

.2To minimize emissions from adhesives, use water-based, solvent-free styrene-butadiene-rubber adhesive for linoleum. Butadiene exposure may cause eye and nose irritation, headaches, dizziness, and vomiting.

.3Apply water based adhesive uniformly using recommended trowel. Do not spread more adhesive than can be covered by flooring before initial set takes place.

.4Lay flooring with seams parallel to building lines to produce a minimum number of seams. Border widths minimum 1/3 width of full material.

.5Run sheets in direction of traffic. Double cut sheet joints and continuously heat weld according to manufacturer's printed instructions.

.6Heat weld seams of safety sheet flooring in accordance with manufacturer's printed instructions.

.7As installation progresses, and after installation roll flooring with 65 kg minimum roller to ensure full adhesion.

.8Cut flooring neatly around fixed objects.

.9Install feature strips and floor markings where indicated. Fit joints tightly.

.10Install flooring in pan type floor access covers. Maintain floor pattern.

.11Continue flooring over areas which will be under built-in furniture.

.12Continue flooring through areas to receive movable type partitions without interrupting floor pattern.

.13Terminate flooring at centreline of door in openings where adjacent floor finish or colour is dissimilar.

.14Install metal edge strips at unprotected or exposed edges where flooring terminates.

3.3APPLICATION: BASE

.1Lay out base to keep number of joints at minimum.

.2Clean substrate and prime with one coat of adhesive.

.3Apply adhesive to back of base.

.4Set base against wall and floor surfaces tightly by using 3 kg hand roller.

.5Install straight and level to variation of 1:1000.

.6Scribe and fit to door frames and other obstructions. Use premoulded end pieces at flush door frames.

.7Cope internal corners. Use premoulded corner units for right angle external corners. Use formed straight base material for external corners of other angles.

.8Heat weld base in accordance with manufacturer's printed instructions.

3.4CLEANING

.1Remove excess adhesive from floor, base and wall surfaces without damage.

.2Clean, seal and apply 2 coats of an approved floor wax plus one wear layer of floor wax to flooring and base surface in accordance with manufacturer's instructions.

3.5PROTECTION

.1Prohibit traffic on floor for 48 hours after installation.

.2Protect new floors from time of final set of adhesive until substantial inspection and to handover of completed project.

3.6COMMISSIONING

.1Train area staff in the care, cleaning and sealing of resilient sheet flooring.

.2Acceptance of maintenance material turned over to owner.
