In-floor, hot water (hydronic) radiant heat systems work well with hardwood floors when site conditions are managed according to manufacturers' recommendations. The opposite is true when conditions are not managed properly. Ambient relative humidity; air, surface and product temperature; subfloor and product moisture content, all must be maintained within specific ranges. Thermostat temperature controls for rooms must be connected to regulate heat 24/7. Without proper management and site control, thousands of dollars or perfectly good product and installation work can be quickly ruined. Surface temperature, as in this image, is most commonly overlooked. An overly hot surface can cause splits, checks, delamination, gaps and buckling in hardwood flooring . Many manufacturers, for example, advise a max surface temperature of 28c (82f). Always check the installation guidelines that (should) accompany the product. Avoid products that do not provide detailed installation guides. www.nfca.ca

Reducing risk… the fewer warranties the better!

2/10/2020

Flooring systems can be complex, involving concrete slabs, moisture barriers, primers, leveling cements, adhesive and finally a floor covering product. Multiple products are often used to complete one flooring system and so the risk of being caught up in a question of failure between two unrelated manufacturers is likely. With fewer manufacturers involved in a system, there's less chance of finger pointing and dispute if an issue arises. For example, switching products like adhesives from the original specification to save money is a common cause of problems in the floor covering industry. Technical support offered by product manufacturers should be consulted to ensure approval of their products when used in combination with other unrelated manufacturers. Manufacturers who do not have accessible and comprehensive technical support should be avoided.

Floors installed in poor lighting get inspected after installation in good lighting

2/10/2020

Floors installed in poor lighting get inspected after installation in good lighting. This increases the likelihood of deficiencies, complaints and hold backs. Quality of workmanship depends on a number of factors, one of them being adequate lighting on site. Work Safe regulations separate different tasks/trades and designate onsite lighting requirements accordingly. All flooring installation work, for example, is in the same lighting category as ‘finish carpentry’ and therefore requires a minimum LUX (light measurement) of 500 be maintained in the area of work (easily achieved with halogen lighting). The Construction Manager is responsible to provide adequate lighting when the NFCA installation standards manual is specified. The floor covering installer is responsible to ensure acceptable conditions exist before proceeding and issue written advice to the Contractor and or Building owner if they do not. www.nfca.ca

Hospitals and Mold don't mix

2/10/2020

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 (Quality Assurance Program) protects building owners from the process of fast track construction which so often overlooks critically important details such as slab dryness, flatness, temperature, porosity, surface profile, approved testing to ASTM standards, and who should take those tests under contract, correctly. The result is an increased likelihood that site conditions will be ready for trained installers, ‘accepted’ instead of ‘rejected’ slabs, quality flooring systems and products installed correctly, on time and with warranties intact lasting for decades as the manufacturer intended. www.nfca.ca

Ensuring skilled and trained installers are on the job

2/10/2020

For the most part, building owners have no idea who is going to show up on site to install their flooring. This is not the case when NFCA is specified along with the Quality Assurance Program third party inspection service. As part of NFCA's membership requirement, all NFCA member contractors must be able to provide Trade or Product qualified installers in accordance with PART A05 TRADE QUALIFICATIONS of the Floor Covering Reference Manual of Canada. They must also be able to provide their own Bond for projects where the NFCA Quality Assurance Program is specified. For building owners concerned about quality of workmanship, this goes along way to ensure skilled and trained installers are on the job. This also raises the value of a trained and certified installer. PART A05 outlines the details and is downloadable for free at: www.nfca.ca/store/c1/Featured_Products.html

HCU (Hydraulic Cement Underlayment) committee forms and meets for the first time January 20th 2020.

1/22/2020

The gap between Division 3 Concrete and Division 9 Finishes (flooring) is a terrible place to be for the General Contractor, Flooring Contractor, Consultant and Developer when connecting the divisions isn’t properly planned. For years, the construction industry has dealt with this issue by avoiding it until the flooring contractor arrives on site to reject (quite rightly) an unacceptable surface. Now what? Short cuts, arguments and threats of litigation for non-performance! For this reason, we created the HCU (Hydraulic Cement Underlayment) Committee to review 1. Why the problem exists 2. Specification solutions that ensure early planning and budgeting, and 3. How to best share solutions with the construction industry. Thank you to the following industry professionals for participating on the committee to shed light on this very important & contentious issue: Monica Baillie (Landmark Architecture), Matt Dalkie (Lafarge), Don Styka (Tarkett), Kathleen Kompauer (KDR Engineering), David Sherley (Custom Building Products), Rob Visscher (Atmosphere Floors), Michael Pereira (EllisDon), Kelvin Klapak (Yellowridge Const.), David Randall (Mapei), Diana Klingner (Canadian National Trades). We look forward to sharing our progress over the coming months.

Seam sealer (adhesive) prevents cut carpet seams from unravelling after installation and it's required according National Floor Covering Association specification

1/8/2020

Seam sealer (adhesive) prevents cut carpet seams from unravelling after installation and is required according National Floor Covering Association (NFCA) specification, The Carpet and Rug Institute (CRI) 104/105 standards and Manufacturer installation guidelines for warranty purposes. To save installation time, seam sealer is often not applied by the installer which leads to the problems such as shown in this image. Seams will quickly unravel in exposed areas as they are constantly tested by vacuuming, dragged furniture legs and foot traffic. It's easy for an inspector to check for the presence of seam sealer after installation using an inspection light, however, it's not easy for the installer to correct the issue afterwards and yet this is one of the most common problems we experience when inspecting carpet installations. www.nfca.ca

Correcting concrete slab surfaces prior to floor covering installation requires time, money - and is outside the scope of work for the trade of 'Floor Covering installer'

1/8/2020

Correcting concrete slab surfaces prior to floor covering installation requires time and money and is outside the scope of work for the trade of 'Floor Covering installer'. This work can however, be taken on as a billable extra. The following is an excerpt from the NFCA Floor Covering Reference Manual regarding this... 2. The General Contractor (GC) shall provide a substrate surface acceptable for the installation of specified flooring materials. Unless otherwise defined by local trade jurisdiction, or agreed to between the GC and the flooring contractor prior to commencement of the Work, the GC will be responsible for: .a Filling and levelling all substrate surfaces including control and construction joints, structural cracks, grooves, gaps, and other irregularities. .b Grinding smooth all ridges, undulations, projections and areas of carbonation and scaling. .c Correcting low density or powdery concrete surfaces in order to provide substrate surfaces that are acceptable for the installation of flooring materials. .d Major patching or installation of an underlayment using products that are suitable for substrate surfaces, and compatible with flooring materials.
