To gravity feed cracks:
Pour neat HT-500 LV 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 HI-TECH Structural Gel or HI-TECH Structural Gel Fast. When the epoxy adhesive seal has cured, inject HT-500 LV with steady pressure. Consult Technical Service for additional information.

To seal slabs:
Spread neat HT-500 LV 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-500 LV. 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.
