Decking Preservers

Protect garden decking from rot, mildew and parasites with an easy-to-apply wood preserver. Available in clear and coloured formulations, these decking preservers can be used to both colour and protect most types of softwood and hardwood decking prior to applying a decking oil.

To keep decked areas in tip top condition and free from mould algae and other biological growth, use a dedicated decking cleaner from time to time.
