TECH TIPS —
Easy protection of cut timber ends, with Abodo’s new Protector End Seal Sealing the ends of external timbers is critically important. Too often the first place of failure in wood decking or wood cladding applications is the exposed end.
Fungal decay requires moisture to develop, and the end grain of wood absorbs moisture at up to 100 times the rate of absorption of the face of wood. This means that on average, the end grain retains more moisture than other parts of the wood, and is more likely to decay first. This phenomenon affects both treated timbers, and naturally durable species. Even “Class 1″ durability species such as Kwila/Merbau, Garapa and Vitex are affected by this problem. It is critical therefore, that the cut ends of wood are sealed prior to application with an end sealant.
End sealants are available as a wax based water repellent, designed to block moisture ingress, or as a chemical preservative, intended to protect the wood from fungal development. Homegrown natural timber specialist, Abodo, has launched Protector End Seal – a one coat colour matched end sealer for the easy protection of cut ends. In one easy step seal and colour the ends of your exterior timber cladding, decking and structural timbers. Learn more at www.abodo.co.nz/endseal
Any cutting of timber, whether from sawing, shaping or planning has the potential to exposure the end grain and allow the uptake of moisture. This is particularly relevant for timber decking, but also for timber cladding or weatherboards.
