7.2.2.4 Installation Instructions
Surface Preparation
The surface to be repaired must be clean, dry, and free of oil, grease and loose matter. The bonding surface should be roughened, using a small chipping hammer or bushing tool, swept clean and blown with clean, dry, oil-free compressed air, or vacuumed clean.
Where the patch will terminate, the concrete must be sawcut and chipped out 1/4" deep.
No priming is required with RM 700 EP, so installation is quick, easy and economical.
Temperature
RM 700 EP should be stored at temperatures between 50°F and 90°F (10°C and 32°C) prior to use. Substrate temperatures may be between 50°F and 80°F (10°C and 27°C).
Mixing
Proper mixing is critical when installing epoxy repair mortars. Do not mix more mortar than can be applied in 30 minutes. Drain the contents of Part B completely into a clean mixing container. Then drain the contents of Part A into the same container. Mix the liquids until the resultant mixture is free of streaking. Next, add the aggregate, a little at a time, while mixing with a mortar mixer or a drill with a mixing paddle. Mix until uniform, being sure that there is no dry aggregate on the bottom or sides of the pail. Do Not Mix Partial Units. Failure to combine components in the proper ratios can result in poor cure or no cure.
Troweling
For large patches, apply RM 700 EP mortar in 2 foot wide strips. Lattice boards will help ensure proper thickness. Spread and finish with a rectangular steel trowel, taking care to minimize trowel marks. Be sure the edges of patch are flush with the surrounding concrete. For smaller patches, a trowel alone may be sufficient.
Trowels may be coated with a commercial solvent such as mineral spirits, to give the finished work a smoother appearance.
Maintenance
RM 700 EP may be cleaned with most floor cleaning detergents. Aggressive solvents should be avoided.
Floor Cleaning
Caution: Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.
Recoat or Topcoating
No recoating or topcoating is necessary. However, if you opt to topcoat the applied mortar, allow it to cure before topcoating. Many epoxies and urethanes can be used. Contact your Hilti Sales Representative for suitable topcoat selections.
