- How to Apply
Surface Preparation (Cured Concrete):
- Surface must be clean, structurally sound, and fully cured 28 days.
- Remove any loose or unsound brick or concrete.
- 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.
- Abrade the surface by abrasive blasting or other mechanical scarification techniques to profile of ICRI CSP 4.
- Water blasting is not recommended.
- For full surface restoration ½-4" (13-102 mm) deep, use MasterEmaco S 488CI.
- Trowel or spray MasterEmaco S 488CI onto the prepared surface and finish with a wood or plastic float.
- Allow the MasterEmaco S 488CI to cure a minimum of 4 hours at 70°F before applying MasterProtect 100CR.
- If the MasterEmaco S 488CI cures for more than 12 hours, scarify the surface to remove all laitance and prime the MasterEmaco S 488CI with MasterEmaco P 130 before applying a coat of MasterProtect 100CR.
- Mixing
- Precondition all components to 70°F for 24 hours before using.
- 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 sides of containers to ensure correct mixing ratios.
- Do not mix more material than is sprayable within the pot life of the mixed material. (approximately 20 minutes at 70°F).
- Mix Part A and B together thoroughly for about 3 minutes using a slow-speed mechanical mixer to obtain a uniform color.
- Priming
- Prime surface with MasterEmaco P 130.
- Apply MasterProtect 100CR after the primer has become tack free (Approximately 3-5 hours at 70°F).
- Recoat with MasterProtect 100CR no later than 24 hours after priming with MasterEmaco P 130.
- Application
Spray Application:
- 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).
- For moderate chemical conditions, apply MasterProtect 100CR at 30 mils (0.76 mm) at approximately 50 ft2 /gallon (1.3 m2 /L).
- 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.
- Do not use this product if the air, substrate, or material temperature is below 45°F or expected to fall below 45°F 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 Masterprotect:
- 100CR Recoat within 24 hours at 70°F.
- After 24 hours, mechanically abrade the entire surface of the coating and clean with acetone or MEK.
- Allow MasterProtect 100CR to dry and reapply coating within 1 hour.
- Clean Up
- Purge the airless system with xylene before material has time to set.
- Cured material must be removed mechanically.
- For Best Performance
- Do not use this product if the air, substrate, or material temperature is below 45°F or expected to fall below 45°F within 12 hours.
- Temperature variations affect the 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 product data sheet and SDS are being used
- Field visits by Master Builders Solutions personnel are for the purpose of making technical recommendations only and are not for supervising or providing quality control on the jobsite.
