Shed Preservatives

Protect and preserve garden sheds with these clear and colour shed preservatives.

These highly effective shed preservatives are designed to protect garden sheds from mould, algae, insect attack, and wood rot, choose from a range of clear and natural wood tone colours to compliment any garden setting.

Before treating any shed, we recommend that it is first cleaned with a mould and algae cleaner to remove and kill any existing green growth or biological spores already present in the wood. Once preserved, sheds can be overcoated with a shed paint or oiled-based shed treatment for improved weather protection.

If overcoating a shed with a paint or exterior wood oil, always use a wood preserver that does not contain water-repellent ingredients such as wax and silicon.
