Wood changes colour when first exposed to daylight. Floor protection from ongoing construction activity should be applied from wall to wall. Tape the protection at seams and NOT to the wood floor surface. NFCA Floor Covering Reference/Specification Manual states: Installed flooring shall be protected with heavy Kraft-paper or other suitable covering as recommended by the flooring manufacturer. Do not use non-breathable sheet or film that could cause condensation to form. This covering must be maintained throughout the remainder of construction period. The overall responsibility for the protection of all installed flooring, from completion of work until the Owner's take-over, is the responsibility of the General Contractor. The flooring contractor will not be able to control the work or actions of on-site workers, or the actions of persons causing damage from setting-up or delivering equipment, furniture, or other items to the site. www.floorcoveringreferencemanual.com
Many flooring products will develop expansion and contraction related issues because they were incorrectly conditioned (acclimated) prior to installation. Never send a floor covering product to a site unless the site is managed at eventual service (living) conditions. NFCA Floor Covering Reference Manual states: 'Product Delivery, Handling and Storage' • Deliver all flooring materials (including adhesives and accessories) wrapped / sealed in original labeled and unopened packaging a minimum of 48 hours before installation to condition materials to correct (service) site temperature and humidity conditions. A 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 proceed with installation until all unsatisfactory conditions have been corrected. Notify the General Contractor in writing of all defects likely to impair finished work. Start of work implies acceptance of surfaces and conditions. www.nfca.ca
Hospitals and mold DON'T mix, which underlines the importance of ensuring correct site conditions exist prior to floor covering installation. The NFCA commercial floor inspection service (QAP), protects building owners from the process of construction which so often over looks critically important details such as quantifiable moisture testing to ASTM standards, and who should take those tests to ensure they are done correctly. The result.... quality flooring, installed, correctly, on time and with warranties in place, lasting for decades as the manufacturer intended. www.nfca.ca
It can't be overstated...remove the word 'smooth' from the specifications when describing acceptable concrete surfaces for toppings and or floor coverings
It can't be overstated. Remove the word 'smooth' from the specifications when describing acceptable concrete surfaces for toppings and or floor coverings, and replace with: 'Provide a Concrete Surface Profile (CSP) of 3 prior to placement of Hydraulic Cement Underlayment (HCU), or a CSP of 2 prior to installation of floor coverings, or as required by the manufacturer of the scheduled topping or floor covering product'. Power Trowels have their place but must be managed so that they don't over do it! Overdoing it creates a multitude of problems including an overly smooth, dense surface which prevents moisture vapour from escaping which significantly slows the drying process. Excessive power towelling also removes surface porosity, required for adhesive bond, which in turn can force the need for shot blasting or grinding which wastes time and money, and doesn't necessarily solve the issues. www.nfca.ca

Most flooring manufacturers have high manufacturing standards and stringent inspection procedures for their finished products. Nevertheless, all types of flooring should be inspected upon delivery and before installation, and if any suspected defects are noted that might give rise to undesirable visual effects, installation should not proceed until the manufacturer has been given a chance to inspect the flooring and an agreed upon course of action has been established.
