There are many different coatings on the current market and there seems to be new products appearing nearly every month, making great new claims. One thing for sure is, that there is no perfect finish for exterior wood. Australia has some of the harshest weather conditions for timber to endure. High UV, hot temperatures, high rain fall, sea salt etc. all contribute to significant weathering and every product has its “pro’s and con’s”. Most products are designed to either penetrate/preserve the timber or create a protective film over the wood. Below is just our observations of some of the coatings on the market.
Always recommend making a test patch so you can see the expected results.
