How much vertical movement is acceptable at timber floor joints?
Tongue-to-groove clearance should not exceed 0.6mm, which permits some differential vertical movement under load. A T&G tolerance at board edges of about 0.4mm makes a good floor, with standards allowing 0.3-0.6mm. FSA Network floor sanders work within these tolerances to deliver stable, quiet floors.
What is the acceptable gap size for solid timber strip flooring?
For solid timber strip flooring, shrinkage gaps over 10 boards can average 0.75mm for an 80mm wide board floor under drier internal conditions. Wider boards show proportionally wider average gapping, and regular expansion gaps throughout the floor's life are acceptable. FSA Network floor sanders can explain normal gapping expectations for your specific floor width and species.
How should I inspect my timber floor for quality?
View the floor during daylight with lights on, from standing positions at a 45-degree angle from eye to floor -- not at unusual angles or close to the ground. Sanding marks should not generally be visible from a standing position, and edging should not scallop. FSA Network floor sanders deliver finishes that meet industry inspection standards.
Are some boards allowed to fall outside grade limits?
Yes, some boards -- less than 5% -- may exceed grade limits without requiring remedial work. Installers should distribute colour and features relatively evenly throughout the floor, and clustering of short boards or board ends is unacceptable. FSA Network floor sanders take care with board layout and feature distribution for the best visual result.
What do the timber flooring grade categories mean?
AS 2796 defines three main grades: Select (minimal features for a cleaner look), Standard or Medium Feature (more character with increased features), and High Feature (prominent features for a rustic look). Grade determines floor character through features like gum veins and knots, not colour variation. FSA Network floor sanders can show you examples of each grade to help you choose.
Does Select Grade timber mean it has no features at all?
No, Select Grade still includes some features such as gum veins and borer activity -- it simply has minimal features for a cleaner appearance compared to Standard and High Feature grades. All grades permit some natural features. FSA Network floor sanders help clients understand that even the cleanest grade includes some natural character.
What has ATFA done to address peaking in hardwood floors?
ATFA developed a revised floor profile that is less prone to peaking for manufacturers to adopt. The standard AS 2796 profiles feature an undercut where pressure concentrates on the top third only during expansion, and a wide undercut can trigger severe peaking. FSA Network floor sanders are aware of profile improvements that reduce peaking risk, particularly for Queensland and NSW installations.
What resources does ATFA provide for flooring professionals?
ATFA provides over 100 technical information sheets, 9 industry manuals, 6 tolerance guides covering different flooring types, a guide to timber flooring applications, 9 how-to videos, safe work method statements, QA records and checklists, and over 60 recorded webinars. FSA Network floor sanders stay current with ATFA industry resources and training.
What tolerance guides does ATFA publish for flooring?
ATFA publishes six tolerance guides covering Bamboo, Engineered, Decking, Hybrid, Laminate, and Solid Timber flooring types. These guides define acceptable performance limits for each product category. FSA Network floor sanders use these tolerance guides as the benchmark for quality work.
What are the Australian Consumer Laws relevant to floor disputes?
Under Australian Consumer Laws, contractors have rectification rights for minor repairs, and consumers have specific protections regarding product quality and service standards. Contacting the original contractor first is the recommended first step for any flooring problem. FSA Network floor sanders operate in full compliance with Australian Consumer Laws.
What information should flooring contractors provide to homeowners?
Contractors should provide detailed maintenance instructions, discuss coating pros and cons before application, explain expected seasonal movement, outline proper cleaning products, and set realistic expectations about finish quality and natural timber characteristics. FSA Network floor sanders provide comprehensive documentation and guidance with every completed floor project.
What are the common contractor errors in timber flooring?
ATFA documents common contractor errors as a key awareness topic, covering mistakes in installation, coating application, subfloor preparation, and expansion allowance. Understanding these errors helps both contractors and homeowners avoid costly problems. FSA Network floor sanders are trained to avoid these common pitfalls through ongoing industry education.
What environmental certifications are available for timber flooring?
Chain of Custody (CoC) timber certification verifies sustainable sourcing, and ATFA documents that timber floors store carbon, with Life Cycle Assessment used to evaluate environmental impact. Some adhesives also feature GREENGUARD GOLD certification for low emissions. FSA Network floor sanders support the use of sustainably sourced and environmentally certified timber products.
What licensing conditions apply to timber flooring contractors in Australia and New Zealand?
Licensing conditions for timber flooring contractors vary between Australian states and New Zealand, and ATFA documents these requirements in their information sheets. Proper licensing ensures contractors meet industry competency standards. FSA Network floor sanders are properly licensed and qualified to perform timber flooring work in their jurisdictions.
What flooring types does the ATFA guide to timber applications cover?
The ATFA guide covers solid timber, pre-finished, engineered, parquetry, laminate, cork, and bamboo flooring applications. Each product type has unique installation, maintenance, and performance characteristics. FSA Network floor sanders are experienced with all timber-based flooring types covered in the ATFA guide.
What topics do ATFA webinars cover?
ATFA has over 60 recorded webinars covering topics including concrete moisture, timber movement, acoustic underlays, insurance work on water damaged floors, gap sizing, grading rules, species identification, slip resistance, recoating, and many more technical subjects. FSA Network floor sanders stay up to date with ATFA education and training.
What is the most recommended approach to dealing with flooring disputes?
ATFA recommends contacting the contractor first for rectification, then obtaining an objective inspection if needed. ATFA Licensed Inspectors conduct impartial assessments analysing history, observations, measurements, and testing. FSA Network floor sanders aim to resolve any concerns promptly and professionally to avoid disputes.
How do ATFA inspections work?
Inspections conducted by ATFA Licensed Inspectors are undertaken objectively, assessing and analysing available information factually. Reports provide impartial analysis covering history, observations, measurements, and testing results. FSA Network floor sanders respect the ATFA inspection process and work to resolve any identified issues.
What is the difference between a full written inspection and a verbal onsite meeting for floor problems?
An onsite verbal meeting is suited for uncertain concerns where the minimum cost applies and comments are verbal only. A full written inspection is for known problems and delivers documented results within 10 working days that can be used in negotiations. Floor Sanding Australia recommends choosing the inspection type that matches the severity of your concern.
