- How to Apply
Surface Preparation:
- Surface must be clean, structurally sound, and fully cured 28 days.
- Mechanically profile the surface of both old and new concrete by shot blasting to ICRI CSP 4, then remove dust by vacuuming.
- Prime with MasterEmaco P 130.
Priming:
- Prime the prepared substrate with MasterEmaco P 130.
- Apply MasterEmaco P 130 at a coverage rate of 150-300 ft2 /gallon.
- Allow MasterEmaco P 130 to become tack free (approximately 3-4 hours) before applying MasterProtect 170CR.
- Mixing
- Precondition all components to 70°F for 24 hours before using.
- Thoroughly stir each separate component (epoxy resin Part A and the hardener Part B) before mixing the 2 components together.
- The mix ratio by volume is 2:1 (A:B).
- Combine 1 part B with 2 parts A in a clean, suitably sized container.
- Scrape the sides of the containers to remove as much material as possible to ensure an accurate mixing ratio.
- Mix the components together using a slowspeed (400-600 rpm) drill with Jiffy mixer for at least 3 minutes until uniform in color with no streaks of color in the mixture.
- Application
As a Coating for Concrete Substrates:
- Apply the mixed product to the clean, primed surface by roller or brush.
- Use the shortest nap roller suitable for the prepared substrate profile.
- Backroll the coating to ensure good wetting of the substrate, uniform thickness of the coating, and removal of any roller marks.
- Apply two 20-mil coats at the rate of 80 ft2 / gal (2 m2 /L) per coat.
- To make the coating slip resistant, broadcast clean, dry sand into the first coat while it is wet.
- Apply sand to the point of saturation (approximately 80 lbs/100 ft2 [3.9 kg/m2 ]).
- When coating is dry, sweep excess sand and apply the second coat of MasterProtect 170CR.
- Recoating must be done within 24 hours at 70°F.
- After 24 hours, mechanically abrade the entire surface of the coating and clean with acetone or xylene.
- Allow MasterProtect 170CR to dry and reapply the coating within 1 hour.
As a Topcoat for Epoxy or Polyurethane Floor and Wall Coatings:
- When applying MasterProtect 170CR over an existing coating, first conduct a test application.
- Lightly sand the surface with medium sandpaper or a 60-80 mesh 3M screen back.
- Vacuum up all dust and solvent wipe floor with acetone.
- Allow to dry.
- Apply the MasterProtect 170CR within 1 hour and according to application instructions.
As a Trowel-down Topping:
- After mixing, slowly add 2-3 parts clean, dry sand by volume to 1 part mixed MasterProtect 170CR epoxy by volume.
- Trowel or screed the sand-modified MasterProtect 170CR to desired thickness (minimum ¼" or 6 mm).
- Clean Up
- Clean equipment immediately after use with xylene.
- Clean hands and skin immediately with soap and water, industrial hand cleaner, or denatured alcohol.
- Cured material can be removed by mechanical means only.
- For Best Performance
- Minimum ambient, surface, and material temperature should be 50°F and rising at the time of application.
- Acceptable service temperatures vary depending on type and frequency of chemical exposure.
- For professional use only; not for sale to or use by the general public.
- Make certain the most current versions of the product data sheet and SDS are being used.
- Proper application is the responsibility of the user.
- Field visits by Master Builders Solutions personnel are to make technical recommendations only and are not for supervising or providing quality control on the job site.
