Master Builders MasterSeal HLM 5000 Low VOC 5 Gallon Pail

MasterSeal HLM 5000, a product by Master Builders Solutions, is a high-grade, single-component, moisture-curing, bitumen-modified polyurethane elastomeric waterproofing membrane. It is specifically designed for exterior below-grade or between-slab applications, providing an effective barrier against water intrusion. This product is ideal for contractors looking for a reliable and durable waterproofing solution for various construction projects.

MasterSeal HLM 5000 is available in four grades: MasterSeal HLM 5000 SL (self-leveling/squeegee), MasterSeal HLM 5000 S (spray), MasterSeal HLM 5000 T (trowel), and MasterSeal HLM 5000 R (roller-applied). This variety allows contractors to choose the most suitable application method for their specific project needs. Each grade is formulated to provide seamless, continuous waterproofing coverage, ensuring maximum protection against water penetration.

The product offers excellent chemical resistance, making it suitable for environments exposed to bacterial attack, select acids, alkalis, and salts. Its elastomeric properties allow for expansion and contraction, accommodating structural movements without compromising its waterproofing capabilities. MasterSeal HLM 5000 has a wide service temperature range, ensuring its effectiveness in all climates. Its seamless, cold-applied membrane eliminates the need for lapping, seaming, and precutting, which simplifies the application process.

MasterSeal HLM 5000 is versatile in its applications, suitable for use on exterior below-grade surfaces on masonry, concrete, and incidental metal. It is also effective for above-grade applications between two-course concrete and within cavity walls. The product's adaptability makes it an excellent choice for waterproofing foundations, basements, retaining walls, and other critical structures where water resistance is essential.
