Staining and Oiling Cedar

Staining or oiling the weatherboards, cladding, shingles
and other Cedar on your property

Staining or oiling the Cedar weatherboards, cladding, shingles, entrance and garage doors, or other timber on your home is a great way to protect the timber from the elements while enhancing the natural look and beauty of the Cedar.

The process of staining or oiling your Cedar starts with a thorough chemical wash of the Cedar on your home to remove the dirt, dust, mould, other contamination and oxidised product.  Then you have the choice of treating the Cedar either by staining it with a timber stain or applying a wood oil.


Once washed and prepared the Cedar is treated with 2 coats of timber stain.

Stain by nature is semi transparent and, while creating a protective surface coating, can allow for the natural grain of the Cedar to show through.

To maintain its weather resistant properties and appearance stained Cedar cladding that is exposed to the elements will likely require a wash and be re-stained with 2 coats of stain after 3-5 years.  See FAQ about re-treatment times.


After the chemical wash, and any preparation required, the Cedar is treated with 1 coat of wood oil.  The wood oil is absorbed into the Cedar, replenishing the natural oils and adding anti-fungal properties. 

Wood oils come with a variety of colour options and the pigment in the coloured oil acts as a UV barrier, which enhances the protection levels for your Cedar.  See FAQ about using a clear oil.

Oiling of your Cedar is a recommended procedure due to the ease of application, maintenance, and the fact that only 1 coat of oil is required for each re-treatment.  That means less labour is required. 

After an initial oiling of either new Cedar weatherboards, cladding, or doors that has been stripped, it is recommended that a “top-up” coat of oil is applied within 12 months to maximize the oil’s protective qualities and further extend the life span of the colour tone.  After this, the re-treatment regime is the same as for a timber stain, but only 1 coat of oil being applied each time.

Changing from stain to Oil

If your Cedar has been stained and you want to change to a wood oil, it may be possible to do a chemical or paint strip of the cladding to remove the existing product completely, bringing you back to a blank canvas of bare Cedar timber ready for the application of wood oil.
