SurePoxy HM Gel is primarily designed for vertical and overhead structural bonding of either old concrete to old concrete or old concrete to new concrete and/or repair mortars, patching and for bolt embedment. Use wherever a rigid, nonsag, gap filling adhesive is needed, such as bonding irregularly shaped structural materials and to seal cracks for injection grouting. Use as a pickproof sealant around windows, etc inside correctional facilities. Use for bonding parking bumpers and barriers to concrete or asphalt.
- Directions
Surface Preparation: Concrete - Surface must be clean and sound. It 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 is the preferred method of preparation to provide a fractured aggregate profile. Also satisfactory are sandblasting or shotblasting individually. Acid etching according to ASTM D- 4260 with 15-20% muriatic acid solution can be used as an alternative, Wash acid and loose mortar off with high-pressure 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 HM Gel is 2:1 (A:B). To mix, proportion 2 parts A and 1 part B into a clean pail. Mix thoroughly for 1-2 minutes with paddle on low speed (400-600 rpm) drill until blend is a uniform color.
The product comes ready to use. The addition of aggregates is not necessary or desired.
Place the prepared mortar in void, working the material into the prepared substrate, filling the cavity. Strike off level. Do not exceed lifts of 4 inches each.
SurePoxy HM Gel can be smoothed easily by coating trowel with Mineral Spirits after void is filled.

Safety & Health
- Precautions
Material forms a vapor barrier after cure. Maximum mortar thickness is 4 inches per lift. Do not thin. Pot life may vary due to different temperatures. Store this product 40-90°F. If stored below 45°F, some lumps appear in the B component, but disappear after combining with component A and does not harm the product. Read Safety Data Sheet before using. Please refer to the General Epoxy Instructions for complete details on proper application during cold and hot weather. When used as a vertical/overhead anchoring adhesive that will carry a sustained tension load, this product is intended only for short-term use. This product is manufactured to meet all aspects of ASTM C-881 which includes no performance standards with regard to creep and/or deformation. It is the responsibility of the engineer and/or contractor to determine the suitability of this product for the intended use. 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.
