• Do not use this product if the air, substrate, or material temperature is below 45 °F (7 °C) or expected to fall below 45 °F (7 °C) within 12 hours.
• Temperature variations affect nonsag properties of this product. Higher temperatures may cause the product to sag; lower temperatures will decrease the workability of the product by causing it to thicken.
• Do not thin; solvents will prevent proper curing.
• 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 are not for supervising or providing quality control on the jobsite.

Cured Concrete

1. The surface must be clean, structurally sound, and fully cured for 28 days.
2. Remove any loose or unsound brick or concrete.
3. The surface must be entirely free of oil, grease, paint, detergent, rust, laitance, or other surface contaminants. Surfaces can be damp but must be free of standing water.
4. Abrade the surface by abrasive blasting or other mechanical scarification techniques to profile of ICRI CSP 4. Water blasting is not recommended.
5. For full surface restoration ½–4" (13–102 mm) deep, use SikaEmaco®-488 CI. Trowel or spray SikaEmaco®-488 CI onto the prepared surface and finish with a wood or plastic float.
6. Allow the SikaEmaco®-488 CI to cure for a minimum of 4 hours at 70 °F (21 °C) before applying Sikagard®-100 CR. If the SikaEmaco®-488 CI cures for more than 12 hours, scarify the surface to remove all laitance and prime the SikaEmaco®-488 CI with SikaEmaco® P 130 before applying a coat of Sikagard®-100 CR.

Priming

Prime surface with SikaEmaco® P 130. Apply Sikagard®-100 CR after the primer has become tack-free (Approximately 3–5 hours at 70 °F [21 °C]). Recoat with Sikagard®-100 CR no later than 24 hours after priming with SikaEmaco® P 130.

1. Precondition all components to 70 °F (21 °C) for 24 hours before using.
2. If using a conventional airless sprayer, mix each component separately, then pour equal volumes of Part A and Part B into a clean pail. Scrape the sides of containers to ensure correct mixing ratios.
3. Do not mix more material than is sprayable within the pot life of the mixed material. (approximately 20 minutes at 70 °F)
4. Mix Part A and B together thoroughly for about 3 minutes using a slow-speed mechanical mixer to obtain a uniform color.

Spray Application

1. Spray apply with a Graco® HydraMax™ 350 (4,000 psi) airless sprayer or equivalent. Use a high-pressure spray hose with an I.D. of 3⁄8" and a Graco® Flex Plus gun with a heavy-duty RAC tip (0.025–0.031).
2. For moderate chemical conditions, apply Sikagard®-100 CR at 30 mils (0.76 mm) at approximately 50 ft²/gallon (1.3 m²/L).
3. Harsh chemical environments require thicker applications at 80–125 mils (2.0–3.2 mm). Two coats may be required to achieve a void-free film on very porous surfaces.
4. Do not use this product if the air, substrate, or material temperature is below 45 °F (7 °C) or expected to fall below 45 °F (7 °C) within 12 hours of application.

Roller Application
Use a ¼" (6 mm) nap synthetic roller. Only mix enough material that can be applied within 20 minutes. Be aware that spraying is the preferred method of application.
Recoating Sikagard®-100 CR
Recoat within 24 hours at 70 °F (21 °C). After 24 hours, mechanically abrade the entire surface of the coating and clean it with acetone or MEK. Allow Sikagard®-100 CR to dry and reapply coating within 1 hour.

Purge the airless system with xylene before material has time to set. Cured material must be removed mechanically.
