Profile – machined smooth 2 sides, slightly rounded corners.
We recommend customers order +10% over and above requirements to allow for waste on your project. We cannot supply every length defect free.
Please Note: Due to Tali’s ultra-dense, multi-directional compact grain, achieving a completely smooth machined finish can be challenging, and areas of raised or lifted grain may occur.
Some final sanding may be required on site after installation. For the best results, we recommend using an orbital sander with 80-grit sandpaper.
Please also be aware that, due to the natural characteristics of Tali, it may not be the most suitable choice for applications where a barefoot-friendly finish is required.
Certification
FSC® (Forest Stewardship Council®) certified stocks, which are sourced from well managed forests and other controlled sources.
Grading
FAS grade, which is effectively 90% A grade and 10% A/B grade. Almost free of knots, worm and Splits. With very low amounts of twist of cupping. Some small end splits maybe present. Please note once hardwood decking is exposed to the elements some fine face and end splits are normal.
Appearance
A Mixed array of colours from light to dark tones, giving a sense of real timber beauty, showing off all the variations that only real timber can offer. The grain pattern is varied with some straighter grain boards and a good volume of 'Zebra style' striped grain.
Lengths
Cut to Metric lengths starting at 2.1 metres and rising in 0.3 metre increments up to a maximum of around 4.5 metres
Machine tolerances
Boards have minimal variation in thickness and width with a tolerance of only +/- 1mm.
Moisture Content
Kiln Dried - circa 12% - 15%
Specie
A dense African hardwood, kiln dried for superior stability. Offering greater density than Yellow Balau and better stability. Rated as 'Class 1' Very Durable. Heavy in weight 900 > 1050kg per m3 which is similar to Ipe decking. Sourced from well-managed and FSC-certified logs. Weight per lineal metre for 21 x 145mm boards circa 3.05kg
Fitting
The frame should be built with larger section sizes of tanalised Softwood ideally 50x150mm or bigger as the frame will generally rot long before the Tali decking. We recommend some coats of further weather protection be added to the frame such as black bitumen to provide further longevity. Good drainage under the frame and ideally some air flow are essential to the life of the frame and also the stability of the decking boards on top. Frame centres are recommended at 400mm – 500mm with 450mm being the industry standard. Tali boards should be trimmed square both ends, removing the end wax. Tali Decking Boards should be securely fixed down where they cross every joist either with 2no. Spax Stainless Steel decking screws 5.0 x 60mm at around 25mm distance from the outer edges of the decking board. Every board should have fixings near each end at a maximum distance of 50mm from the ends. Alternatively this stable decking can be installed with Deckwise Extreme 4mm space hidden fixings, lay the boards on the frame and router the sides where needed to accept the clip. Follow the same guidance for fixings spacing as the above face fixing points. The Deckwise router bit is available on our website for this perfect groove depth for side fixings the hidden fasteners.
Finishing for silvered weathered look
Install decking and leave to silver over time no maintenance required.
Finishing maintaining/enhancing colour using Owatrol Trade quality products
1st Option (recommended)
1) Leave for approximately one year to allow natural weathering to breakdown Millglaze*
2) Wet timber scrub off ground in dirt, while still wet apply Net-Trol Wood cleaner & Colour restorer 3) Leave for 10 – 20 minutes (do not allow to dry apply more Net-trol or damp with water mist)
4) Wash off with plenty of water
5) Leave to fully dry usually 24 hours
6) Apply Textrol penetrating oil wet on wet two coat application
7) Repeat approximately every 18 months or as timber fades this will depend on exposure to sunlight
2nd Option
1) To achieve oiled finish on newly installed decking Millglaze* must be removed first, to do this wet timber and apply diluted Prepdeck (dilute 1predeck:1water for Ipe)
3) Leave Prepdeck to work 10 – 30 minutes do not allow to dry into decking spray mist water if required.
4) Rinse off Prepdeck with plenty of water
5) Neutralise Prepdeck with diluted Net-trol (1:1water) to stop Prepdeck reactivating when it becomes wet
6) Leave to fully dry usually 24 hours
7) Apply Owatrol Deks Olje D1 saturating oil (note this oil has minimal UV protection so will fade)
Note 1 – Always work small manageable areas of decking of say 2m x 1m rather than trying to tackle the complete deck in one go and risk products_BK_Test like Prepdeck or Net-Trol drying into the decking
Note 2 – If decking has become faded do not just apply more oil, the surface must be prepared first with Net-Trol following steps 2) to 6) on ‘1st Option’
*Millglaze is the compacted surface which occurs during the machining process. The heat from the cutters draws natural oil in the timber to the surface compacting the fibres and creating a hard slightly shiny surface which will prevent an oil finish from penetrating as intended.
