What is Weathering and Why is it Important?

What is Weathering and Why is it Important?

When you have invested in a new deck, there are two key steps you need to take before coating the timber, which will help enhance its lifespan for the long-term.

WEATHERING YOUR DECK

The first step is weathering, which involves exposing the timber to rain, sunshine and everything in-between. The purpose of weathering is to help remove the tannins and oils from the surface of new timber. If not properly removed from the surface, Tannins can cause the timber’s appearance to look patchy and discoloured once coated. If your deck is undercover, be sure to hose it down regularly to replicate some of the effects of natural weathering.

Typically, new bare timber needs to weather for between four and six weeks, although more oily species like Spotted Gum benefit from at least a couple of months of weathering prior to coating. During this period, timber can become grey in colour – a natural part of the process that indicates the deck is weathering successfully. It signals that the lignin holding the timber’s surface fibres together is breaking down, which will open up the grain and allow the coating product to penetrate more deeply into the wood, offering greater protection against the elements.

CLEANING YOUR DECK

Before you begin coating your deck, you need to give it a thorough clean. Use the following guide to ensure the surface is entirely free from contaminants.
