HLM 5000 Roller Masterseal: Liquid, Cold-Applied Elastomeric Waterproofing Membrane System:
How does it work?
MasterSeal HLM-5000 is a one-component, moisture-curing, bitumen-modified polyurethane elastomeric waterproofing membrane for exterior below-grade or between-slab applications. Questions? Contact Us
- Plywood (exterior)
- Exterior below grade (on masonry, concrete, and incidental metal)
- Above grade (between two-course concrete and within cavity walls)
- Parking garages and concrete tanks
- Plaza decks and malls
- Fountains and pools
- Balconies and planters
- Below-grade slabs
- Walls and culverts
- Sea walls, dams and reservoirs
A test application is always recommended before proceeding with entire application. NOTE: Finish coat must be applied in a pinhole-free, continuous membrane for waterproofing integrity.
1.Select the grade of MasterSeal HLM 5000 that best meets individual job requirements. Use MasterSeal HLM 5000 T for trowel application, MasterSeal HLM 5000 S for spray application, MasterSeal HLM 5000 R for roller application or MasterSeal HLM 5000 SL for squeegee application.
2.For horizontal applications, empty contents of pail and spread immediately to ensure workability. Best results are obtained by marking off 125 ft2
(11.61 m2) areas and evenly spreading the contents of a 5 gallon (18.93 L) unit with a rubber-edged notched squeegee. Repeat the above procedure until the entire surface is covered.
3.For vertical applications, apply by trowel, roller or spray at the rate of 25 ft2/gallon (0.6 m2/L). Best results are obtained by marking off 125 ft2 (11.6 m2/L) and evenly applying the contents of a 5 gallon (18.93 L) pail.
4.Verify the applied thickness with a wet mil gauge as the work progresses.
5.The integrity of the cured membrane on a horizontal surface may be verified by damming the entire area and flooding with water to a minimum depth of 2″ (51 mm) and allowing the water to stand for 24–48 hours. Visually inspect the bottom surface to check for any water penetration. If repairs are necessary, the area should be drained
and allowed to dry before reapplying MasterSeal HLM 5000. After reapplication, the area should be tested again for membrane integrity.
What are the unique features?
