NOTES ON INSTALLATION
For Best Performance
- Precondition these materials to approximately 70°F (21°C) for 24 hours before using.
- Water content should not exceed 0.9 gallons per 55 lb bag during application.
- Minimum application thickness is 3⁄8” (10 mm).
- Maximum application thickness is 6” (152 mm) per lift.
- Do not mix partial bags.
- Minimum ambient and surface temperatures should be 45°F (7°C) and rising at the time
- of application.
- 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 Sika personnel are for the purpose of making technical recommendations only and not for supervising or providing quality control on the jobsite.
SURFACE PREPARATION
- The substrate must be structurally sound and fully cured (28 days).
- Saw cut the perimeter of the area being repaired into a square with a minimum depth of 1/4" (6 mm).
- The surface to be repaired must be clean, free of laitance, and saturated surface-dry (SSD) following ICRI Guideline no. 310.2 to permit proper bond.
Reinforcing Steel
- Remove all oxidation and scale from the exposed reinforcing steel in accordance with ICRI Technical Guideline No. 310.1R.
- For additional protection from future corrosion, coat the prepared reinforcing steel with Sikagard® P 8100 AP.
MIXING
Wet Process
- Add 0.68–0.77 gallons (2.57–2.91 L) of potable water per 55 lb (25 kg) bag of SikaEmaco®-211 SP.
- Mechanically mix using an appropriately sized forced-action mortar mixer. Pour approximately 90% of the water into the mixing container, then charge the mixer with the material. Add the remaining mix water as required.
- Mix for 3–5 minutes to reach a homogeneous consistency.
APPLICATION
- Apply in accordance with ACI 506R.
- Apply while taking proper consideration for rebound and compaction around reinforcing steel. The successful application depends primarily on the skill of the nozzleman.
- When applying multiple lifts, scratch the preliminary lift before the initial set. Apply the succeeding lift after the preliminary lift has reached the final set. If the succeeding lift will not be immediately placed, keep the surface continually moist.
- Cut off or level the application as required, matching the original concrete elevation.
- In rapid-drying conditions (e.g., hot, dry, and windy weather) use Sika® Antisol® ER 50 evaporation reducer.
- Finish the final surface as required.
CURING TREATMENT
Wet cure for a minimum of seven days or cure with an approved curing compound compliant with ASTM C 309 or preferably ASTM C 1315.
CLEANING OF TOOLS
Clean tools and equipment with clean water immediately after use. Cured material must be removed mechanically
