H&C® Broom Finish Repair
H&C Broom Finish Repair is perfect for salt damaged driveways and sidewalks. It's a cementitious non-slip surface that goes on very thin and has the typical broomed concrete look. It can be used with any H&C Color Pack to provide additional color options.
Where to Use
- Parking decks
- Pool decks
H&C Broom Finish Repair has excellent bond and freeze/thaw resistance making it ideal for driveways and parking decks in any climate. It is a trowel and squeegee applied topping for interior and exterior concrete repairs, with the ability to slope and fill spalls and low areas.
- 1/2" drill - must be a slow or variable speed drill to control the shear and mixing speed.
- Mixing paddle
- 5 gallon pail
- Tape and paper to mask all areas for protection
Concrete must be cured. Remove all laitance, efflorescence, chemical contaminants, grease, oil, old paint, and other foreign matter. The prepared surface must be clean and structurally sound. Shot blasting, scarifying or water blasting may be necessary to achieve the proper profile for both a chemical and mechanical bond. Acid etching or other treatments should be evaluated for profiling. H&C Concrete Etching Solution is an effective, safe alternative to muriatic acid. Substrate must be 40°F and rising before installation. Surface at 90°F and above must be cooled before installation. Dampen area with fog tipped sprayer before using, leaving no puddles.
On irregular slabs requiring extensive patching, it is recommended to use H&C® Quick Patch & Repair. H&C Broom Finish Repair will sag and shrink in deeper pits and voids. H&C Broom Finish Repair may be installed in multiple lifts with no brooming to create a superior smooth surface. As product dries, scrape and use leaf blower to remove loose material.
Base Coat: Apply in ambient and substrate temperatures between 40ºF and rising and 90ºF. Cover or mask all areas requiring protection with tape and paper so that material does not bond to unwanted surfaces. Dampen concrete before applying base coat. Concrete MUST be damp with no standing water prior to base coat application. Mix water at the rate of 7 – 8 qts. to 1 - 50 lb. bucket. Mechanically mix to a lump-free consistency. Pour mixed material onto the existing damp slab and steel squeegee a tight coat (usually less than 1/16"), depending on desired finish. This will fill in any slight inconsistencies in the concrete surface and leave a flat, even base that is essential for successful application. The base coat may be broomed immediately after placement, which will give a superior surface for the following finish broom coat to mechanically bond. A very irregular slab with divots and spalls should be patched prior to application of base coat. For slight irregularities do not broom the base coat. The broom will pull away material from the irregularities. As the base coat dries, scrape the surface and sweep and use leaf blower to remove loose material.
Finish Coat: The broom finish coat is exactly the same as the base coat including the ratios and mixing instructions. Dampen the base coat. Again pour out the mixed material and trowel to approximately 1/16" thickness. The material can be broomed with a concrete broom immediately after placement. For a finer broom finish allow the product to set slightly before brooming. Clean the broom frequently to prevent the finish coat from balling up. Have sufficient extensions for broom handle to prevent inadvertently stepping onto broom finish. Steel-cleated golf spikes or spikes are useful if the slab is so large that it cannot be worked completely from the sides. A piece of plywood to step off the slab with spikes will prevent turf from being tracked back onto the new broom finish. A piece of scrap cardboard to shake off the broom will facilitate easier clean-up. As product dries, scrape and use leaf blower to remove loose material. To complete the installation, two thin coats of H&C Solvent or Waterborne Sealer are required.
