Cuprinol Rollable Shed & Fence Treatment
No one relishes painting their fence, there is a new product now available however that cuts the time it takes in half. Cuprinol Rollable Shed & Fence Treatment applied with a Cuprinol Rapid Roller is twice as fast as a brush, The Rapid Roller looks and works like a paint roller, unlike a paint roller however it is specially designed to give even coverage over the typically uneven nature of fencing panels and sheds.
Available in five different colours, Cuprinol Rollable Shed & Fence Treatment requires you to apply only one coat, is a low odour formula that is safe for plants & pets, is wax enriched for improved water resistance and lasts six times as long as creosote.
SAFE for plants implies safe for humans but I would check with the company to verify. good luck LJ
