FULL INSTRUCTIONS:
SURFACE PREPARATION:
1. Mechanically remove loose, unsound, contaminated concrete.
2. Concrete must be free of materials such as paint, oil, curing compound, bond breaker, etc. that will inhibit bonding.
3. Thoroughly clean extraneous material such as dirt, loose chips, and dust from concrete surface. If compressed air is used, it shall be free of oil.
4. Concrete surface shall be dry.
MIXING:
1. Organize personnel and equipment before mixing.
2. Use 1 part water to 2 parts of material.
3. Mixed material should have a temperature of about 70°F. Warmer material will set faster than expected and cooler material will have slower strength gain. Control the mixed temperature by protecting the bags of repair material from temperature extremes and adjust the mixed temperature by using hot or cold water.
4. Add potable water first then add material while mixing mechanically with a drill and mixing paddle.
5. Do NOT add any other admixtures. Do NOT add sand, aggregate, or cement.
6. Mix until smooth, uniform, and lump-free (usually 3 to 5 minutes).
7. Do NOT re-temper.
8. Clean mixing bucket and tools between batches.
PLACEMENT:
1. Place material onto the dry substrate.
2. Maintain surface and ambient temperature between 45°F and 100°F during and for 4 hours after placement.
3. Protect adjacent surfaces with drop cloths, waterproof paper, or other means to maintain them free of material splashes, water, and debris.
4. Place material immediately after mixing.
5. Apply material in one pass and avoid re-troweling.
6. As the material becomes stiff (usually 10 to 20 minutes) use a trowel to shave or cut the material to the desired shape.
7. Sanding may be begun as soon as material has dried and must be completed within 24 hours.
8. Material may be painted 4 hours after it has dried because the Ph matches the concrete Ph at that time.
CURING:
1. None required.
CLEAN UP:
1. Clean all tools immediately after use.
2. Clean excess material from surrounding areas immediately.
