- Uses
Use whenever a high performance, very strong, dimensionally stable, chemical resistant grout is desired. Use where loads, shocks, impacts and operational stresses are routine. K Pro HP Grout offers excellent chemical resistance. It may be used as a grout for precision alignment under dynamic load conditions, for vibration dampening filler for rotating equipment, support of chemical tanks, vessels and rotating equipment as well as anchoring bolts, reinforcing bars and dowels into concrete, rock, masonry. Use for compressors, crane rails, diesel generators, gas turbines, gear cases, engines, and storage tanks.
- Directions
Surface Preparation: Metal surfaces to be in contact with K Pro HP Grout should be dry and free of grease, paint, or rust. Sandblast to a bright metal surface. Concrete on which the grout will bear should have attained its full designed strength and shrinkage before grouting. All concrete surfaces that are to encounter K Pro HP Grout should be chipped approximately 1” in depth or until the large aggregate is exposed to remove laitance and provide a rough surface for good bonding and shear strength. If the concrete is oil soaked, chip until no oil or contaminants are visible. Cover all shims, leveling screws, wedges, and blocks, which are to be removed after grouting with wax prior to pouring.
Forming: Make all forms liquid tight to prevent seepage. Use a putty or caulking compound to seal all forms. If any parts of forms, or other areas, are not to be bonded to K Pro HP Grout, then treat with 3 coats of paste, auto wax or polyethylene to prevent adhesion. Long or deep pours should contain number 4 or 5 rebars on approximately 12-18” centers parallel to the equipment to reduce stress cracking. The rebars should be placed approximately 2” below the grout surface and if the rebar is tiered, the bottom rebar should be located 2” above the foundation surface. Very deep pours can be done in several lifts of approximately 12-16” each.
For bolt grouting, hole diameters, 1/4" to 1/2" greater than the bolt diameter are normally employed. Under 3,000 psi. concrete, 15 times bolt diameter is recommended for depth. Hole spacing is also important to avoid stress interaction caused by holes placed too closely or near the edge.
Mixing: Condition all ingredients to 70°F or more. Open cans and pour the contents of both containers into larger container. Stir both components together thoroughly. Pour all this liquid onto the 3-4.5 bags of K Pro HP Grout Aggregate in a mixing container or mortar mixer. Mix aggregate and liquid epoxy together until uniformly blended, approximately 3 minutes with paddle or low speed drill (400-600 rpm) until grout is uniform in color and consistency. Do not vary the ratio of resin and hardener or add solvent or water to change the consistency. For free-flowing, self-leveling grout, use only 3 bags. If a stiffer mix is desired, add an additional 1.5 bags of K Pro HP Grout Aggregate. Place K Pro HP Grout as soon as thoroughly mixed. Time will reduce the flowability somewhat.
Placement: Substrate must be at least 50°F and rising. Grout should be placed from only one side to avoid air entrapment. Rod or vibrate the material to achieve complete filling and consolidation is not necessary when only 3 bags are used but are necessary with 4.5 bags.
When placing under pads, maintain a head to insure intimate contact between grout and plate. A smooth finish can be achieved by steel troweling if 4.5 bags are used but is not necessary when using only 3 bags. Clean all equipment with SurePoxy Thinner before material hardens.
Curing:
The following chart is a guide for determining final cure times. The temperatures shown are of the baseplate and foundation, not ambient temperatures.
Temp. °F Cure Time, Hours
90 12 80 24 70 36 60 48 50 72 Notes: Do not thin. Store above 60°F. Cold temperatures slow strength gain and high temperatures speed strength gain. K Pro HP Grout is not designed for applications requiring resistance to continuous temperatures over 130°F. Do not use radiant heating. This warms the grouts upper surface more than below. The grout surface therefore cures in a thermally expanded state and after dissipation of heat, produces stress that tends to make the grout “curl up”, results in cracks in the foundation corners just below the grout line. For best results, fabricate temporary shelters around the equipment to be grouted and pre-warm the equipment and foundation. Try and prevent the grouting being performed in direct sunlight during hot days. Either erect a shade or perform this operation during the cooler part of the day or night. K Pro K Pro HP Grout has excellent flow characteristics and generally does not need assistance, but flow can be assisted using rods, trowels, or other pushing tools. Do not vibrate as this will induce excessive air entrapment and result in a poor bearing area upon curing. Head pressure is the preferred way to assist flow. Construct a head box or funnel 1-2 feet deep to place the grout in hard to reach places. Never allow the level of grout to fall beneath that of the base plate, because this will result in trapped air and voids. This product is intended for horizontal applications only. Please read Safety Data Sheet before using. Please refer to the General Epoxy Instructions for complete details on proper application during cold and hot weather
