Decking Preservers

Wooden Decking Preservers

Using a decking preserver will help to protect decking timbers, posts and supports from mould, algae, fungi, wood rot and insect attack, all of which can degrade untreated wood over time.

Types of Wood Preservative

There are 2 types of wood preserver, water based and solvent based, both of which are available in clear and coloured formulas. Although solvent based wood preservatives penetrate deeper in to the timber, changes in legislation regarding high VOC’s (Volatile Organic Compounds) wood treatments means that many traditional solvent based wood preservers are slowly being phased out or re-formulated.

Water based preservers for decking still provide excellent protection. They are less smelly to use and less harmful to the user and environment.

Most brands of Wood preservative are generally available in both clear and coloured formulations. This means that decking can be treated but kept looking natural or coloured. Using a wood preservative as a stand alone treatment will normally keep wood protected from biological threats but will only provide limited weather protection. For this reason, we recommend that when using a wood preservative on decking, it is always over-coated with a suitable decking oil.

How to preserve wooden decking

For the best protection preserve all or as many of the timber components as possible with two coats of wood preservative. This should include both sides, edges and especially the end grain or sawn ends of the timber. The same should then be done with a suitable decking oil or http://www.home-gardener.co.uk/decking-stain/ after the preservative has fully dried. This will help to protect vulnerable areas that are near or that come into contact with the ground from condensation and moisture.

Choosing the right decking preserver

If you’re planning on painting or using a varnish type decking stain its worth remembering that some decking preservers contain wax. Although this is fine with decking oils, the wax content will prevent decking paints and varnish type stains from adhering to the wood. This could result in the paint or stain flaking off prematurely.
