Super low viscosity for deeper penetration, high strength, two component epoxy adhesive binder. HT-150 SLV conforms to ASTM C-881, Types I and IV, Grade 1, Classes B & C. It also meets USDA specifications for use in food processing areas. An excellent epoxy adhesive for use in crack grouting by pressure injection or gravity-feed, and as a general purpose binder for sealing many concrete slab conditions and for making epoxy patching mortars and grouts.

  • Pressure-injection for cracks in structural concrete, masonry, wood, etc.
  • Gravity-feed of cracks in horizontal concrete and masonry.
  • Epoxy resin binder for epoxy mortar patching and overlay of interior, horizontal surfaces.
  • Seal interior slabs and exterior above-grade slabs for water, chlorides, mild chemical attack and to improve performance.
  • Grouting bolts, dowels, pins, etc.

To gravity feed cracks:
Pour neat HT-150 SLV into  vee-notched crack. Continue placement until completely filled. Seal underside of slab prior to filling if cracks reflect through.

To pressure-inject cracks:
Use automated injection equipment of manual methods. Set appropriate injection ports based on system used. Seal ports and cracks with HT Structural Gel or HT Structural Gel Fast. When the epoxy adhesive seal has cured, inject HT-150 SLV with steady pressure. Consult Technical Service for additional information.

To seal slabs:
Spread neat HT-150 SLV over slab. Allow penetration. Remove excess to prevent surface        film. Seal interior slabs and above grade exterior slabs only.

For use as an epoxy mortar:
Prime prepared surface with neat HT-150 SLV. Place prepared epoxy mortar before primer becomes tack-free. Place the epoxy mortar using trowels. Compact and level with vibrating screed or trowels. Finish with finishing trowel. Exterior application may darken with ultra violet exposure.
