Gazebo Maintenance:

The Mercia Gazebo is made from pressure-treated timbers for excellent durability and longevity. These products have an anti-rot solution in the timber structure, improving rot resistance. Mercia Garden Pressure Treated products come with a 15-year Anti-Rot guarantee. The manufacturer recommends that if you want to paint your garden gazebo with a different colour, ensure the treatment you choose is recommended for pressure-treated timber.  The manufacturer requires the gazebo to be treated with waterproofing upon construction. Applying a water-repellent product to your wooden garden bar is required for even more longevity and extra protection.
