ToggleWhere Can You Use Bitumen Paint?
Thanks to its weatherproofing, corrosion-resistant, and adhesive qualities, bitumen paint finds application in diverse settings. Its primary function is to act as a protective shield for buildings and construction materials, including metal guttering, fire escapes, stairways, ladders, railings, and fences.
Durability and Longevity
It boasts impressive durability, offering long-lasting protection against environmental factors. When applied to a felt roof, it can endure for 2 to 3 years before showing signs of wear. On more porous surfaces like masonry, its longevity extends even further, making it a reliable choice for extended protection.
