What causes timber to move/bow?

Timber is a natural hygroscopic material which releases or absorbs moisture in response to ambient changes in temperature and humidity.  

Being a seasoned material it is prone to move due to storage and moisture levels. 

Porta's timber mouldings are graded in accordance with the AS4785 & AS2796 standards.

What is the recommended height for Chair/Dado Rail?

Although originally designed to protect walls from damage inflicted by the backs of chairs, the chair rail today primarily serves as a decorative function – encircling the perimeter of a room and/or separating different wall finish treatments.  It is generally affixed horizontally along a wall at a height of approximately 900mm – 1000mm, or about 1/3 of the way up from the floor. 

Another tip is you can place your chair up against the wall and mark where it hits the wall.

How do I affix my timber mouldings?

Nailing is by far the most common method for affixing timber. When installing mouldings nail glue and nails/fasteners in strategic places along the length of the timber is recommended.

It is also suggested that you pre-drill holes in your timber before installing to prevent splitting in particular when working with Hardwood such as Tasmanian Oak.

What angles do I need for the mitres?
For square corners, 45 degree mitres are required, however the method used depends on your application – whether the moulding is to be affixed to a flat surface or wall as in the case of, for example, skirting or chair rail, or whether the moulding is to be affixed to two different surfaces at 90 degrees to one another e.g. wall and ceiling, as in the case of crown, cornice or scotia.

Can you route Porta panels?

Yes, Porta’s pine panels are constructed from quarter sawn clear grade timber components which are then edge-glued together in a huge press (a process termed “laminated”)  Being quarter sawn and of close lamination manufacture, the panel is up to 40 % more sturdy and stable than a standard panel of the same thickness, yet it can be routed and cut as one would any solid timber panel. 

Covering holes and nails on my mouldings

You can easily cover nail holes and blemishes in timber mouldings with filler/putty. Cover the area with the filler and give it a light sand before applying your final finish.  There are a wide range of wood fillers available from Hardware stores, which are tinted to suit the colour of  the timber you are trying to match, which is ideal for staining purposes.

How do I remove the product label from timber?

We suggest gently peeling the label off and lightly sanding to remove any residual gum. For smaller labels carefully remove with steam.

Older dry labels can be removed with the use of a citrus based solvent such as De-Solv-it or Un-du, then allowing to dry and gently sanding.
