SurePoxy HMLV is recommended for base plates and bolt grouting and for use as a low viscosity, penetrating sealer. SurePoxy HMLV is ideal for pressure injection high modulus grouting. When mixed with SurePoxy Aggregate, it provides an excellent setting bed for precast concrete, marble and granite.
- Directions
Surface Preparation: Concrete - Surface must be clean and sound. may be dry or damp but free of standing water. Remove oil, wax, curing compound, laitance, and other foreign matter as per ASTM D-4258 and D-4259. Waterblasting followed by shotblasting the preferred method of preparation to provide fractured aggregate profile. Also satisfactory are sandblasting or shotblasting individually. Acid etching according to ASTM D-4260 with Kaufman Products Concrete Floor Etch or 15-20% muriatic acid solution can be used as an alternative. Wash acid and loose mortar off with highpressure water until slush is removed. Test with litmus paper to be sure acid is removed. Final rinse with 1% ammonia solution is beneficial. Steel - Sandblast to appropriate finish.
Proportioning/Mixing: The volumetric ratio of SurePoxy HMLV is 2:1 (A:B). To mix, proportion 2 parts A and 1 part B into a clean pail. Mix thoroughly for 3 minutes with paddle on low speed (400-600 rpm) drill until blend is a uniform color. Add approximately 7 parts by volume of SurePoxy Mortar Aggregate or K Pro HP Grout Aggregate to 1 part neat SurePoxy HMLV to produce a mortar. Mix thoroughly.
Application Grout Cracks: Gravity feed SurePoxy HMLV into horizontal cracks, pressure feed into vertical or overhead cracks. Be sure and insert ports into crack first. Then seal around ports and along crack with proper gel. Anchor Bolts, Rods, etc - Use either neat or with SurePoxy Aggregate, added at the rate of 5-7 parts to 1 part of SurePoxy HMLV by volume. If used neat, hole size should be 1/8" larger diameter than imbedded item.
Mortar - Mix with approximately 5-7 parts aggregate.
Seal Slabs - Spread neat SurePoxy HMLV over surface of slab with flat rubber squeegee or roller. Allow to penetrate, squeegee off excess before it hardens.

Safety & Health
- Precautions
Do not thin SurePoxy HMLV. The contractor shall use the test method prescribed ACI 503R to determine that the preparation produced a surface capable of providing tensile bond strength greater than 250 psi. If stored below 45°F, some settling and lumping appear. Read Safety Data Sheet before using. Please refer to the General Epoxy Instructions for complete details on proper application during cold and hot weather. Please refer to Recommended Field Procedures for Epoxy Injection Using Cartridges when necessary.
The NTSB has stated that epoxy adhesive products are approved for short term loads only and should not be used in sustained tensile load adhesive anchoring applications where adhesive failure could result in a public safety risk. Consult a design professional prior to use.
