How to prepare your deck for coating

Category Banner

Ready for summer, Aotearoa? Got the BBQ sizzling and the sunscreen stocked up? There might be one thing you’ve missed—getting your deck sorted. Just like us, our decks need protection from the harsh New Zealand sun. They’re where summer memories are made—whether it’s soaking up the rays, cooling off in the pool, or having the whānau over for a good catch-up. So give your timber some love and keep it looking great with a fresh coat of stain or oil. But before you do, don’t skip the most important step… prep!
