WHEN TO OIL, STAIN OR PAINT YOUR DECK
If your deck has been previously finished with either an oil or stain coating, it is recommended that you use a product that is compatible as this will give you the best result.
Here are a few tips on how to tell how your deck has been treated previously.
Oil: You will know if your deck has been treated with oil as oiling will not change the colour of your timber, hence it will appear natural in colour. If a timber is oiled and left too long, the timber will begin to turn grey in colour indicating it is time to re-treat the deck.
Stain: You will be able to tell if your deck has been stained as the wood colouring will appear blotchy when weathered. The other key sign to look for when distinguishing whether the boards have been stained is the stain will sit on top of the timber and not stain the sides of the timber boards.
Paint: You will be able to tell your deck has been painted as there will be no sign of timber colourings, instead a colour has been painted over the top. The paint may be beginning to chip or crack, indicating it is ready for a fresh coat.
