Deck Restoration Services

Hardwoods such as Kwila come from tropical climates that have a lot of moisture in the air that makes the timber less likely to dry out and splinter. New Zealand’s harsh climate and intense sun quickly dries out the timber causing it to splinter, and Kwila is the most susceptible to this.

We recommend maintaining new Kwila decks by an annual application of linseed oil stain that will nourish the timber and stop it drying out.

There is very little that can be done to fix Kwila that has already dried out and splintered, short of replacing the boards. Because of this, Kwila is becoming less popular as a decking timber with other hardwoods such as Vitex and Garapa becoming more popular.

A wood stain generally requires a top up coat every 12-18 months to replenish the nourishing oils and UV blockers. We can arrange an on-going maintenance schedule with you following the restoration process that will include a light clean followed by a recoat of the wood stain. In between scheduled maintenance, a mild detergent is all that is needed to remove any bird droppings or spills, and a spray with a moss and lichen inhibitor during winter can also help. It is important to not use harsh deck cleaning agents that may remove the oils contained in the stain. Painted surfaces generally last longer than stained ones but are more susceptible to abrasion.
