- .06 Pre-Approved Materials / Systems:
- The following laminate flooring manufacturers have been pre-approved subject to meeting specification requirements.
- SPEC NOTE:
Where different laminate flooring systems are used on the same project, define each in the specification and differentiate each on drawings and Finish Schedule by number / name using the following example:
- Type LF1 - Typical laminate flooring.
- Type LF2 - Laminate flooring in [specify area]
3 • EXECUTION
.03 Installation of Flooring Underlayment:
Select appropriate material:
.05 Installation of Bases and Trims:
.06 Installation of Stair Coverings:
- Review all conditions to ensure substrate conditions and levels, environmental conditions and work by other trades is acceptable prior to commencing work including moisture content. Refer to Part 1 installation requirements noted herein.
- Ensure concrete is tested for moisture and alkalinity and that moisture and alkalinity levels are in accordance with manufacturer and NFPA requirements.
- Ensure plywood subfloor installation meets minimum NFCA requirements.
- Check substrate levels with a metal straight edge and ensure that they are free from all bumps, ridges, and other imperfections detrimental to flooring installation. Grinding of concrete substrates and the addition of a cementitious self-levelling underlayment shall be by others in accordance with NFCA requirements. Such work by the flooring contractor shall be defined as additional work at additional cost.
- Fill low spots, cracks, joints and holes with substrate filler as required to limits defined by NFCA to correct substrate imperfections.
- Remove paint, varnish, oils, and other compounds not compatible with flooring underlayment.
- Seal and prime substrates in accordance with manufacturer's recommendations.
- Sand wood substrates smooth and vacuum clean as required, providing a suitable smooth surface for laminate flooring installation.
.03 Installation of Flooring Underlayment:
Select appropriate material:
- Install [sheathing paper] [moisture barrier] over concrete slabs below or on-grade lapping joints 150 mm (6") and seal with tape.
Install [acoustical] [resilient] underlayment over acceptable substrate surfaces [including stair treads] in strict accordance with flooring manufacturers written requirements with edges butted together (not overlapped) and with continuously taped seams.
- Verify strip flooring direction with [Consultant] [Owner] before starting installation.
- Install laminate flooring in strict accordance with flooring manufacturer's directions and to minimum NFCA requirements to areas and patterns scheduled and detailed on [drawings] [pre-approved shop drawings] and Finish Schedules.
- Provide expansion void at perimeter vertical interfaces (walls, millwork, adjacent floor finishes, and at openings as required) of width and in accordance with flooring manufacturer's recommendations and to minimum NFCA requirements using temporary blocking if and as required and expansion material as recommended by flooring manufacturer.
- Install laminate flooring planks from right to left, [free floating] over [panel underlayment and] resilient underlayment] with [mechanically] [glue] fastened tongue and groove joints].
- Unless otherwise indicated, install flooring symmetrically about room centre line and parallel to long dimension of room [and corridor], continuous through doorways, and cut to fit all projections, with all joints straight, true to plane, and with minimum half plank width at perimeters. Stagger end joint locations a minimum of 250 to 300 mm (10 to 12") and seal all cut ends as recommended by manufacturer.
- When required by manufacturer install specified adhesive to laminate joints in strict accordance with manufacturer's written instructions.
- Drill or cut holes for flooring penetrations in strict accordance with manufacturers requirements and seal perimeters of wet areas, i.e., in expansion gap under stoves, fridges, and dishwashers with a clear silicone sealant.
- At door frames:
- Wood frames: Undercut frames and allow for a minimum expansion clearance of 6 mm (1/4").
- Metal frames: Cut flooring to fit around frames - Do not undercut frames. Provide 5 mm (3/16") expansion space and fill with colour-matched perimeter sealant.
Verify if adhesive in joints is part of manufacturer's requirements.
.05 Installation of Bases and Trims:
- VInstall wood base (and quarter round if required) over expansion void at perimeter of flooring secured to vertical interfaces using nails in accordance with NFCA requirements. Ensure base does not contact floor surface and is not secured to it.
- Install protective edgings / reducer strips and laminate thresholds to all exposed laminate flooring edges and interfaces with other flooring materials as required to suit conditions, fixed as recommended by the manufacturer and to NFCA requirements.
- Install metal thresholds at openings and where indicated and attached to adjacent rigid floor surface. Where thresholds cover an expansion space, ensure that they are fastened to the substrate and not to laminate flooring, to allow flooring to move (i.e., expand and contract) under the threshold.
.06 Installation of Stair Coverings:
- Install laminate flooring to treads and riser faces fitted tightly to adjacent wall surfaces allowing for expansion as required.
- Install specified wood base and stringers fitted tightly to horizontal and vertical stair surfaces and to wall surfaces without gaps or voids.
- On completion remove waste, vacuum clean, and inspect flooring installation for apparent defects and adjust as required. Such cleaning does not include final cleaning for Substantial Performance.
- Avoid static loads on newly installed flooring until adhesives have thoroughly set.
- Do not permit any traffic over installed flooring until site-finish coats have dried and cured (for a minimum period of seven (7) days unless otherwise specified by coating manufacturer.).
- The overall responsibility for the protection of completed flooring to acceptance by the Owner shall be the responsibility of the General Contractor who shall reasonably prohibit all other work and traffic over flooring and provide a temporary breathable protective covering acceptable to the manufacturer. Do not use non-breathable sheet or film covering that could cause condensation to form.
- Subsequently remove protective covering and dispose of same and make good defects to flooring installation caused by other trades.
