Garden Decking Preservers

Protect garden decking from rot, mildew and parasites with an easy-to-apply decking preserver. Available in both clear and coloured formulations, these decking preservative treatments can be used to both colour and protect most types of softwood and hardwood decking. To further extend the life of wooden decking, we recommend the application of a Decking Oil, after the wood preservative has fully dried. To keep decked areas in tip top condition and free from mould algae and other biological growth, use a Decking Cleaner. from time to time.
