How do I coat a deck in cold weather?

How do I coat a deck in cold weather?

Summer’s gone and the barbie is packed away. But that doesn’t mean you can ignore your deck until spring. Protecting timber through the winter months is essential; a good coat of stain or oil will keep moisture out, and make sure it’s ready for use again next barbecue season.

There’s a sweet spot for re-coating; if the wood is too hot, the stain will dry too quickly and look patchy; if the wood is too cold, the deck could start to have a milky or wrinkled appearance as moisture is trapped under the coating.

1.Don’t coat wood with a surface temperature of less than 10°C. Be warned; timber can often be cooler than the external temperature.

2.Choose a water-based product. These dry faster than solvent-based products, and are more robust when applied in cooler temperatures.

3. Always apply product in the direction of the grain to ensure a smooth finish. In cooler temperatures, ensure you’re not applying too much product. This can start to look milky and cause re-coating issues. Don’t overwork the product on the timber.

4. If you’re painting interior timber, warm the room to above 18 degrees to help in the drying process and avoid a milky finish.

Help! My deck still has a milky finish. What should I do?

The easiest way to get rid of heat rings is by using a hairdryer to draw the moisture out of the timber. Keep it on a low-heat, and move it around the damaged area, making sure one area doesn’t get too hot. As the coating gets warm and the moisture starts to evaporate, the white marks should start to disappear. If the timber is fully cured, wipe milky marks with a cloth soaked with methylated spirits. This should draw the moisture out from the coating. Rub gently so you don’t damage the coating.
