It is easy to see why liquid-applied membranes (LAMs) are one of the fastest growing sectors of the construction industry. Systems are becoming an increasingly popular choice for commercial roofing projects due to their versatility, durability, and reliability.
Roofs are most vulnerable at the seams and around detail areas. LAMs cure to form a completely seamless and joint-free waterproof coating, providing a hard-wearing and long-lasting waterproofing solution, even around complex details.
While they are a great choice for new build projects because of the long guarantees that systems offer, LAMs also are ideal for repair or refurbishment projects. They are suitable for overlay and help extend the life of the roof without the cost of replacement. Systems are usually compatible with a wide range of roof substrates, including:
H.B. Fuller’s Apollo Roofing has been supplying single-component, moisture-triggered, polyurethane waterproofing systems for over 15 years.
The Apollo-branded Moisture-Triggered Polyurethane Liquid Waterproofing System is a cold-applied multi-layer system, consisting of a base-coat, an embedded glass fibre mat layer to reinforce the coating, and one or more top-coat layers. Polyurethane is already a very tough material on its own, but the reinforcement layer ensures the coating provides a lasting durable waterproofing solution.
Independent tests prove that our Moisture-Triggered Polyurethane Liquid Waterproofing System provides long-lasting performance (up to 25 years) and can withstand significant stress due to its carefully selected elastomeric properties. This provides high levels of flexibility, reducing the occurrence of potential cracks due to the coating mitigating any movement in the existing structure. It also utilises the latest fast-curing and cross-linking technology to ensure speed, ease, and consistency of application.
In addition to LAMs, we offer a wide range of high-performance primers to improve the adhesion of the substrate you are working with. Using the appropriate primer is vital to maximise the longevity of the roof and to comply with tested data.
When applying LAMs, different substrates and applications will present different complexities. Primers come in a variety of different forms and are often substrate specific. Each LAM primer has been formulated for a specific application/substrate, from overlaying asphalt, RBM, metal and various single-ply membranes.
