Cutting and pasting old specs into new documents devalues the purpose of the spec, leads to incorrect installation process and can result in perfectly good flooring products under performing or failing altogether. There are generic, Canadian floor covering specifications online at https://lnkd.in/ezn6udg available to design authorities for specifying floor covering installation work. This specification resource guides the process of floor covering installation and advises all parties on product acclimation, correct indoor environmental conditions, testing requirements, sub-floor flatness requirements, surface preparation, installer qualifications and clearly assigns scope of work to the correct party. Include the correct language in your next floor covering spec with the words: 'Perform all work in accordance with the NFCA Floor Covering Reference Manual of Canada and the manufacturer’s recommendations for the type of work that applies'. With this done, industry standards and correct procedure can be referenced throughout the installation.
To simultaneously protect budgets, deadlines and product warranties, planning ahead is critical. This means ‘Scope of Work’ (who is responsible for what on site) must be clearly understood in advance so that the Construction Manager and Flooring Contractor have accurately covered their work scope in their initial bid for the work and can subsequently afford (based on original bid) to work together throughout the build. This way deflected, curled slabs can be properly managed before floor coverings are scheduled, correct ASTM moisture testing requirements can be budgeted and factored into the schedule, surface prep reviewed understood and managed properly and indoor ‘service’ conditions provided prior to and during installation. With these four items properly specified, understood by all involved and planned for, installers can do the work they are trained to do and clients will stand a better chance of getting the flooring they expect... on budget, on time and with warranty intact.

Timely provision of an acceptable surface to the floor covering installer is necessary to avoid delays and ensure quality
The timely provision of an acceptable surface to the floor covering installer is necessary to avoid delays and ensure quality. The Floor Covering Reference/Specification Manual of Canada states 'The General Contractor shall provide substrate surface level and flatness conditions acceptable for floor covering materials (straightedge measure of 3/16" over 10'). This shall include grinding or sanding of ridges, undulations, projections, and areas of carbonation and scaling and filling and leveling of expansion joints, cracks, grooves and other irregularities. Where patching or leveling is required, the use of an approved Hydraulic Cement Underlayment is recommended'. For existing slabs the same applies including the removal of any and all surface contaminants including old adhesives. The flooring contractor may take on this work as a billable extra. www.floorcoveringreferencemanual.com
Luxury Vinyl Planks and Tiles change shape according to changes in temperature that exceed manufacturers' recommendations. Avoid the problems of post-installation shrinkage (gapping between planks) and/or expansion (lifting at joints). Deliver all flooring materials (including adhesives and accessories) wrapped/ sealed in original labeled and unopened packaging a minimum of 48 hours before installation, to a round-the- clock (night time too) temperature controlled environment (20c / 45% RH). Confirm the temperature of the subfloor surface, the installation space (room), the floor covering product and related materials have ALL reached the recommended temperature before installing. SPEC NOTE: Sufficient, secure, dry, and heated storage space to store floor covering materials, tools and equipment necessary for installation shall be provided by the General Contractor or Owner. Do not deliver floor covering products to site until correct conditions exist. www.nfca.ca
