    Tannins are chemicals produced by plants to help protect them against insect attack. Tannins can appear as brown stains on the wood and, being mostly water soluble, can be washed from timber by the rain, stained pavers and other surfaces. Tannin stains are often mistaken for a timber coating that has been washed off by the rain.
    New or un-seasoned hardwoods such as Merbau, Tallowwood, Spotted Gum, Jarrah and Iron bark all contain natural tannins. These tannins need to be extracted prior to coating. This can be done naturally by leaving the timber to weather in the elements for a minimum period of 6 months. As an alternative, this weathering process can be accelerated by applying Cetol BL Tannin and Oil Remover to the timber.

    What’s the difference between oil based and water based coatings?

    Oil based coatings penetrate the wood better, they are also more durable. As this type of coating takes longer to dry, it tends to produce a more even finish. An advantage of using an oil-based coating is that it will not cause the wood grain to raise.
    However oil based coatings emit a strong odour whilst drying and drying times are typically longer than water based coatings. Additionally oil based coatings require mineral turps to wash up brushes and equipment.
    Water based coatings are more mildew resistant than oil based. They also don’t produce as much odour or harmful fumes and are non flammable. As they are based on water they are naturally more environmentally friendly and don’t emit VOCs (Volatile Organic Compounds).
    They dry quicker and allow faster recoat times and retain their colour longer. Clean up requires only soap and tap water.

    How can I clean my deck if it has gone grey?

    The grey results from the reaction of the sun’s UV rays with the wood fibres of the deck. First, clean the deck with Cetol BL Wood & Deck Cleaner to remove the grey without damaging the wood, then apply your desired finish.

    What is the difference between softwoods and hardwoods?

    The difference between timber from softwood and hardwood species results from differences in their cellular structure and chemical composition. The term hardwood or softwood has no direct relevance to the hardness or softness of the wood.
    Hardwood timbers are ideal for high strength structural applications, while their natural durability also makes them perfect for external applications, such as decking and cladding, and for interior flooring and stairs.
    Softwoods have a wide range of applications and are typically less expensive than hardwoods. The most common type of softwood is treated pine.

    What is Reeded Decking?

    Reeded decking has had grooves carved into it along the length of the timber. The grooves may be on one or both sides of the timber. Originally, the reeds were designed to be laid downwards to allow air movement around the joists they were laid onto to help prevent rotting.
    However, the reeds are often laid upwards as many believe they stop slipping. This is not the case as grooves trap water and encourage the growth of algae which makes the surface more slippery. Coatings applied to reeded decking have a shorter lifespan than those applied to smooth, un-reeded decks.

    How do I get the right stain colour?

    Before you apply the stain to your piece, test it!
    Testing your stain is very important because the colour of a stain, unlike a paint, is influenced by the wood it is applied to. You need to see the stain colour on your particular wood before you can be sure of exactly what colour you will end up with. Our sample pots are a great and economical way of giving you confidence of the colour you choose.
    Before you apply the stain to your piece, try it out either on an inconspicuous area or on a sample wood. Stain it in the same way you plan to stain your piece, following all the same steps. In this way, you can adjust the colour and get it right before you tackle the real thing.

    Do I need to clean the wood before coating?

    Absolutely. Even new wood needs to be cleaned thoroughly prior to coating. When the timber is clean it guarantees a strong adhesion of any top coats.

    How long will the Sikkens coating last?

    It varies with each project. However colour can fade with general use and weather conditions. For timber decks, we recommend to keep your timber looking its best that you re-coat approximately every 12-18 months.
