Timspec Decking

At Timspec, we offer a range of decking options, including traditional timbers and modern composite solutions. Suggestions and guidelines to choose the right decking for your project are below.

Lengths Available

Generally, decking is only sold on a mixed length 'random spread' specification, this means that if you order 100 lineal meters, you will get a range of lengths within thespread.

Certain species such as Kwila, Radiata, Western Red Cedar and Accoya have good length specifications, so you can expect a nice mix of short, medium and long lengths.  Other timbers such as Jarrah and Vitex, have shorter lengths so, expect to encounter short lengths. This is generally not a problem as the installer would usually stagger the shortest lengths around the deck so, they are not too obvious. 

Moisture Content

Timber is hygroscopic, so it will swell and shrink as it gains/lose moisture from the environment. The moisture content of the sub-frame must not exceed 20% at the time of fixing as problems may arise later resulting in excessive timber movement (shrinkage) if the framing is too wet. 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

The expected serviceable life span will depend on the timber specified. Refer to Timspec installation manual for more information on durability of the various species we offer, or check out our EVA-Last composite decking.

Profile

Usually, decking is available with smooth face on both sides. A reeded one face is available on request(also known as griptread) which has a smooth back. 

Bleeding

Most timber 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 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 preferable astimber naturally swells and shrinks, and may push up a smooth shanked nail. It is also recommended 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 900mm apart and at least 100mm 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.
