All TrueGrain products (except for TrueGrain SugarCane and Bamboo and the TrueGrain Natural range) are made from natural timber veneer, dyed all the way through, then laminated together and re-sliced to make veneer in unique colours and patterns. TrueGrain Sugarcane and Bamboo are made from sections of undyed or heat-treated bamboo stems, laminated then sliced. TrueGrain Natural is made from the species of its name, undyed. The nominal sizes of TrueGrain leaves are 2500mm x 640mm or 2800mm x 640mm for the dyed timber based veneers, 2440mm x 340mm for TrueGrain Bamboo and 2500mm x 430mm for TrueGrain SugarCane and 2500mm x 350mm for TrueGrain Natural veneers. The thickness of TrueGrain is 0.55mm/0.6mm, except for TrueGrain WinterWhite, which is 0.7mm.
TrueGrain timber-based veneers are made from Poplar from plantations or from Obeche, selectively logged from managed forests. TrueGrain Sugarcane and Bamboo are made from plantation grown bamboo.
TrueGrain veneer can be used in the same applications as natural timber decorative veneers. Like natural timber veneers, it is not generally suitable for use in wet areas such as vanity tops, or exterior applications such as external doors and walls. Veneered panels should never be used in the raw state but must always be finished with a suitable coating. Like natural veneer and dyed materials such as fabric and paint, TrueGrain may fade or discolour on exposure to light. Using the correct type of coating can significantly reduce this, but it can never be entirely eliminated (see below).
It is best for TrueGrain to be finished with a high-quality, non-yellowing, 2-pack Acrylic-urethane, with manufacturer approved UV inhibitors in the sealer and top-coats. Because the performance of coatings varies between manufacturers, and coating suitability depends on the desired application, we recommend that fabricators prepare TrueGrain veneered panels to test their coating system for colour stability and any other properties desired in the intended application, such as wear resistance and hardness. This is particularly important if alternative coating systems are used, for instance Single-pack lacquers and Acid-catalysed lacquers.
Veneer and veneered panels should not be stored exposed to bright light, excessive heat, high-humidity, chemicals, water and other liquids. To protect from the effects of light and dry air/wind, always keep the raw veneer and uncoated veneered panels completely covered with a panel of flat plywood, MDF, etc. Surface finished/coated panels should not be exposed to extended periods of direct sunlight or other bright light.
Like other timber veneers, TrueGrain should be glued onto substrates such as Particleboard, MDF and Plywood, with a balancing back, by professional panel-layers using panel presses. (Hand lamination is not generally recommended.) Normal veneering Cross-linking PVA or UF glues are suitable. It is best for TrueGrain to be laminated “tight” (smooth) side towards the glue-line and to be Slip-matched, unless the pattern indicates otherwise. TrueGrain Caramel should be Reverse Slip-matched. If any of the TrueGrain veneers are Book-matched, a visual colour shift may be noticeable.
As with other dyed products such as fabrics, all TrueGrain made from natural timber veneers may vary slightly in colour and pattern from dye-lot to dye-lot (approximately 1000 sheets). For consistency across a project, all veneer should be ordered at one time, identified by the project name. In the case of very large projects, it is best if several months’ notice is given to Briggs Veneers, with information on the quantity of veneer and date required, so we can look to having multiple crates manufactured in one dye-lot. The same coating system and processing methods should be used across the entire project, that is, across all packages.
With regards to TrueGrain SugarCane and Bamboo, although we endeavour at all times to provide material as consistent as possible, because these are undyed natural products made from different bamboo stems, there may be some colour variation within and between leaves.
TrueGrain is made with Urea-Formaldehyde glues. Formaldehyde emissions comply with the European E1 Standard (0.1ppm) and are less than 1.4 mg/m2h (according to the EN 717/2 method). To prevent build-up of formaldehyde, ensure adequate ventilation in places where TrueGrain packs are stored. The dyes used in TrueGrain veneers do not contain heavy metals. As in all wood working operations, it is essential that adequate protection is taken against the contact and the breathing of wood dust when processing, and that normal workplace hygiene practices are followed.
As it is not possible to cover all associated manufacturing materials and conditions, the end-user is responsible for carrying the necessary tests to check that the veneer, fabrication methods, associated materials and coating are suitable for the desired application. Discolouration due to sunlight or extended periods of bright light cannot be considered to be a material defect. The limit of liability for TrueGrain is up to the value of the goods supplied by Briggs Veneers, and supply is subject to our standard terms and conditions.
