Warehouse Roof Sealing


Warehouse Roof Sealing



Global’s range of products can also be used to waterproof warehouse and factory roofs. Our seamless membranes are applied via an airless spray pump to all surfaces ensuring a water-tight finish.

NOVALAST 151 LTM is a solvent free, acrylic membrane system designed to provide a continuous water-tight seal in situations where considerable structural movement of the substrate may be anticipated. The excellent waterproofing and durability characteristics of this product make it an ideal choice for flat pitch roofing and the sealing of metal, masonry, fibro and concrete surfaces for long-life performance through a wide range of climatic and environmental conditions. NOVALAST 151 LTM has an elongation of 350% for 2mm cured film thickness and has great insulation properties that would reduce the internal temperature by up to 40%.

NOVALAST 151 LTM was used to seal a 52,000m2 roof in Canning Vale in Western Australia with great success.
