Cuprinol Exterior Wood Preserver (BP)

Cuprinol Exterior Wood Preserver (BP) is an exterior lightly pigmented wood preservative for rough sawn and smooth garden timbers, such as cladding, fencing, sheds, greenhouses and summerhouses. It contains active ingredients that penetrate into the timber to prevent rot, decay and blue stain. It is a water-based product that can be used near plants.

Apply 2-3 uniform coats to achieve a total coverage range of between 5 and 6.2 m2/l. Allow the previous coat to soak in before applying the next, usually 2-6 hours under normal weather conditions. This product is wax enriched to repel water. Recoat within 2-3 days of previous coat. Note that the colour in the can may be different to the final shade when dry. The product becomes effective against blue staining and wood rotting fungi when the required amount has been applied and allowed to dry. Do not apply in temperatures below 5°C, in damp conditions or if rain is likely before the product has dried. Apply evenly, avoiding splashing of surrounding plants, brickwork, glass, PVCu, etc. Any splashing should be cleaned up immediately (whilst still wet) with water and household detergent. Excessive spillage on plants should be rinsed off immediately before drying. TIP: where a strong colour change is involved, more coats may be required. If using more than 1 pack it is advisable to mix them together in a larger container or finish in a corner before starting a new pack.
