Product description

Product Description

Sikalastic HLM 5000 GC (Formerly MasterSeal HLM 5000 GC) is a liquid, cold-applied, one-component, moisture-curing, bitumen-modified polyurethane elastomeric waterproofing membrane for exterior below-grade or between slab applications.

Apply Sikalastic HLM 5000 GC when substrates are dry and air temperatures are +40 °F to +90 °F (+4 °C to +32 °C); for application at temperatures below +40 °F (+4 °C), consult Technical Services.

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.

Appreciable properties develop within 24–48 hours at 75 °F (24 °C) and 50% relative humidity. Protect Sikalastic HLM 5000 GC from traffic during curing.

Product Uses

  • Concrete
  • Plywood (exterior)
  • Exterior below grade (on masonry, concrete, and incidental metal)
  • Above grade (between two-course concrete and within cavity walls)
  • Parking garages
  • Plaza decks and malls
  • Balconies and planters
  • Below-grade slabs and split slabs
  • Foundation walls
  • Walls and culverts

Product Characteristics and Advantages

  • Sikalastic HLM 5000 GC can be applied minimum 72 hrs after the concrete is poured, or as little as 24 hrs following the removal of the forms
  • Can be applied to damp concrete
  • Available in standard and high-build systems to prevent water penetration
  • Passes ASTM C 1305
  • Elastomeric product accommodates expansion and contraction
  • Wide service-temperature range, making Sikalastic HLM 5000 GC suitable for all climates
  • Chemical resistance to select acids, alkalis and salts
  • Seamless cold-applied membrane eliminates lapping, seaming and precutting
  • Does not require hot-melt equipment
  • Compliant with ASTM C 836 and SCAQMB
