Timspec Hardwood Decking

ITI Timspec offers a range of Hardwood decking species. Suggestions and guidelines to make a right choice are: lengths available, moisture content, durability, profile, bleeding, splintering, hardness, width of the board and cost.

Lengths Available

Generally, decking is only sold on a mixed length specification, this means that if you order 100 linear meters, you will get a range of lengths.

Some of the species such as Kwila, Radiata, Western Red Cedar and Yellow Cedar have very good length specifications, so expect a nice mix of short, medium and long lengths. Other timbers such as Jarrah and Vitex, have short length specifications, so expect lots of shorter lengths and few longer ones. Short lengths are not normally a problem as the installer would usually scatter the shortest lengths around the deck so they are not too obvious.

Moisture Content

Timber swells and shrinks as it gains/loses moisture from the environment.  If you are ordering decking timber, make sure it has an appropriate moisture content (usually Air Dried is sufficient, but some timbers may need to be Kiln Dried).

Durability

Durability is explained in more detail in our installation manual on downloads page. Basically, decking should be long lasting and stable. Many factors are considered to build a durable deck which includes choosing right species, giving the right treatment, fixing correctly and the list goes on. For example, we would not recommend using Macrocarpa for decking because the boards may have sap on the edge that will decay very quickly. Find more information on decking in our installation manual : Here.

Profile

Usually, Decking is available with smooth face on both sides. Reeded one face is available on request (also known as grip-tread) which has a smooth back. 

Bleeding

Most timber species will bleed. which is leeching of a coloured sap or tannin. For many timbers, the amount of bleeding is minimal and will have no effect. Please contact ITI Timspec for a suggestion on the minimum and maximum bleeding species.  

Fixing

It is recommended that only decking screws are used for fixing decking to joists. This is because as the timber naturally swells and shrinks, it may push up a smooth shanked nail. It is also recommended (but not as common in practice) to pre-drill screw pilot holes.

Care & Maintenance

Care must be taken to ensure that the timber and accessories are kept clean and dry, and are not damaged whilst in storage awaiting application. Extra care is to be taken while handling timber profiles to ensure that they are not damaged. Upon delivery, timber is to be stacked flat and level on bearers/dunnage that are a maximum of 900 mm apart and atleast 100 mm off the ground. Timber should either be sorted inside an enclosed building or covered with an additional waterproof layer and protected from the elements when stored outside.

Decking Maintenance 

The serviceable life assumes regular maintenance. Appearance will degrade overtime unless timber is coated and both the coatings and all aspect of the decking system are maintained. 

Maintenance requirements will vary, depending on the species of timber, site, location, aspect, exposure, and coating selected, but in general terms, annual cleaning of the deck should be carried out to ensure the surface is free from moss, fungal and organic growths, and air-borne pollutants. 

This should be carried out using water and a mild detergent and soft nylon brush, ensuring all the residue is washed away. Avoid using harsh chemicals, and high pressure waterblasters as these may damage the surface of timber. 

Periodically, relocate furniture, pots, and planters etc. to reduce th erisk of water trapped on deck surface and to ensure a more even weathering.

Re-application of the stain or oil finish, to the cleaned decking, should be carried out in accordance with the coating manufacturer's instructions.
