In 2014 the Australian Building Codes Board and the aligning State Government Regulators introduced changed regulations for slip resistance on stairs and ramps within the Building Code of Australia (BCA), part of the National Construction Code (NCC).
When timber floors are sanded and coated it is generally either an existing dwelling or new dwelling that is nearing completion.
Often internal stairs are made from timber or they are clad with timber flooring products. In other situations, timber flooring will be laid after the existing stairs are in place and existing floor covering have been removed.
Solid timber strip floors may be laid directly to joists or over sheet subfloors of particleboard and plywood
In years gone by air-conditioning was afforded by only relatively few, however nowadays air-conditioning is common especially with new dwellings having air-conditioning to part or all the dwelling.
It has become common practice to use adhesives in conjunction with fasteners to fix timber and bamboo flooring to the subfloor.
For as long as there have been timber floors there have been squeaks and it is generally accepted that many floors will make some noise when walked on.
When we refer to slip resistance with timber flooring products we are generally referring to the slip resistance of the coating on the product.
A high percentage of timber floors are laid over concrete slabs. Often a moisture vapour retarding barrier is applied to the slab or a black plastic membrane may be used.
Taber testing is quoted by many coatings manufacturers as a means of conveying predicted wear resistance by a standardised method.
This information sheet provides guidance and test results to the fire hazard properties of common solid timber flooring used in commercial Class 2 to 9 buildings under the National Construction Code.
There have been instances of floor failure due to tenting following the installation of overlay timber floors when direct adhesive fixed to concrete slabs during hot and very dry conditions.
There have been instances of floor failure due to tenting following the installation of overlay timber floors when direct adhesive fixed to concrete slabs during hot and very dry conditions.
Timber floors are often installed in high-rise and unit developments, where it is necessary to reduce noise transmission to acceptable levels through to the dwelling below.
When installing a solid T&G timber floor directly over a concrete slab, moisture vapour barriers may be applied
The correct use of resistance moisture meters with timber floors and how to interpret the results is of prime importance.
Some coatings will darken or yellow with time while other coatings may result in a floor becoming lighter with time.
Edge bonding can occur more so with some finishes if they penetrate gaps at board edges and act as an adhesive, and thereby bonding groups of boards together.
In this information sheet, we will look at the various aspects that can cause coatings to fry and provide us with a better understanding of how to avoid it, and also, should it occur, how to address it.
Outgassing, evaporation, diffusion and off-gassing are some of the terms used to describe the movement of volatile species from a coating that has been applied onto a surface.
