Ronseal Shed and Fence Preserver has been specially formulated to give colour and protection to sheds and fences. The deep penetrating 2-in-1 formula eradicates woodworm whilst preserving the wood to prevent rot and decay. The unique formula contains added water repellents, waterproofing the timber from the damage caused by water ingress. Before You Start Ensure all surfaces are clean, dry and free from surface coatings such as paint, varnish or stain etc. Where timbers are suffering from decay, before applying Ronseal Shed and Fence Preserver, remove all decayed wood and replace with sound, treated timber. Cut out and burn all decayed wood at least 45cm beyond the area of damage. Application Shake well before use. This is important to ensure uniform colour. Ronseal Shed & Fence Preserver can be applied by brush or dipping. Where possible, end grains should be treated by dipping to ensure complete penetration. Apply a minimum of 2 even coats of Ronseal Shed and Fence Preserver, covering all faces, sides and joints, paying particular attention to the end grain. Refer to all coverage guidelines. The second coat should be applied after the first coat is fully dry. Avoid contact with bitumen, bitumen felt or mastics and plastics.
