Deck tips for Outdoor Rooms

When it comes to decking, the key to achieving a professional-looking result is a well-prepared surface. Ensure that the timber is well seasoned, free from natural extractives (tannin) and clean.

New Decks:
The most important step for homeowners installing a new deck is thorough seasoning. Seasoning is a natural weathering process that can take between three to six months. During this time, the new timber releases its natural extractives (tannins) which appear as a dark-coloured run-off.
Many people assume that decking timber does not need to be seasoned because it is kiln dried during the manufacturing process, but this is not the case. Proper seasoning is particularly important for oily, tannin-rich timbers such as Merbau, which have become a very popular choice for decking in recent times.
Coating unseasoned timber results in the premature break down of the applied coating and within a short space of time will leave discolouration and staining under the coated surface.
If completing the deck in a shorter time is desirable, new Sikkens Cetol BL Tannin and Oil Remover can extract the majority of tannins in a matter of minutes.

Existing Decks:
For established decks the primary concern is ensuring the timber is clean and free from dirt and grime. Thorough cleaning with a product such as Sikkens Cetol BL Deck and Wood Cleaner not only rejuvenates old decking by drawing out dirt and grime but allows the new coating to properly penetrate and adhere to the timber for long-lasting protection.
If the deck is in bad condition, it may be necessary to strip back and sand the surface before recoating. Signs a deck may need to be recoated include peeling, flaking, discolouration, mould growth or greying of the timber surface.
Any areas affected by mould or mildew must be properly treated before recoating, otherwise, mould will continue to grow underneath the fresh paintwork.

Choosing a coating:
Timber is a porous material and should always be coated after cleaning to protect the surface from dirt, grime, UV damage and moisture. Whether oil or water-based, always choose the best timber coating you can afford.
A quality coating such as Sikkens Cetol HLSe will last much longer (up to two years) than cheap decking oils, which may need to be applied every few months to keep the timber looking its best.

Cleaning and coating tools:
A pressure washer is ideal for cleaning hardwood decks such as ironbark, Merbau and blackbutt (pressure washers are not recommended for use on softwood). Otherwise, a good hard-bristle brush works well to remove stubborn dirt and grime.
When coating a freshly cleaned deck, use a pure-bristle brush for a smooth, even finish. Applicator pads and paint rollers are not ideal for coating timber as they can apply product unevenly. Additionally, rollers can aerate the timber coating causing air bubbles that will leave ‘pock-marks’ once the coating has cured.
The Sikkens Ezee Deck Brush is an ideal tool for applying timber coatings. The soft pure-bristle brush ensures coatings are worked evenly into the grain of the timber, while a long broom-like handle prevents the need to get down on hands and knees.
