Way back in May 2016, Preschem was asked to give a presentation to the Victorian Woodworkers Association. The topic was Why Timber Changes Colour, which we turned into a news article for the Preschem website. We decided to revisit this topic as we were recently contacted by Shane, who had developed an issue with Aussie Clear Light exterior timber oil on his new Silvertop Ash deck. He noticed that 2 weeks after he oiled and it rained and that the Aussie Clear Light had pretty much disappeared. What was alarming, was the timber had gone quite grey where the rain had fallen.
Rising damp is a common problem that affects many homes and buildings. It occurs when moisture from the ground travels up through porous building materials, such as bricks, mortar, and timber. Moisture in timber frames that have been affected by flood water, can also be trapped behind plaster sheet, tiles and architraves. This remains sight unseen. When this moisture reaches the timber frame of a building, it can cause a number of problems, including the growth of white rot.
