C2 Protector - 5L

Product Information

Crete Colors C2 Protector - Water, Oil and Stain Repellent Concrete Sealer

C2 Protector is a penetrating, reactive treatment that provides water, oil and stain repellency for every kind of finished concrete floor. Treated surfaces retain their natural texture and breathability. C2 Protector improves stain resistance and simplifies maintenance cleaning of interior and exterior, horizontal and vertical concrete surfaces. Solvent-based and low-odor, this VOC compliant protective treatment is easily applied with pump-up sprayers.

Crete Colors C2 Protector Advantages

• Resists oil and food stains, and repels water and water-related stains
• Works on floors previously treated with C2 Super Hard, C2 Hard or C2 Hard Blend.
• May be applied to surfaces previously treated with C2 Seal or C2 Ultra Seal.
• Appropriate for application to any cured concrete, from steel troweled to highly polished.
• Low-odor suitable for interior application to occupied buildings.
• Fast drying – reduces down time.
• Treated surfaces “breathe” – does not trap moisture.
• Can be burnished.
• Coverage rate higher than typical water repellents or other stain-resistant impregnators
• Re-coatable; penetrates and bonds to concrete previously treated with C2 Protector – no stripping required

Limitations of C2 Protector

• May slightly darken concrete surfaces.
• Not for use on surfaces exposed to standing or pooling water.
• Will not compensate for structural defects or bridge cracks, gaps and voids.
• Not suitable for surfaces subjected to below grade water exposure.
• Will not provide UV protection to concrete flooring colored with C2 Tint or C2 Color Hard. C2 Ultra Seal or C2 Seal would be more appropriate.

VOC Compliance

C2 Protector is compliant with the US Environmental Protection Agency's AIM VOC regulations.

Preparation

Protect people, vehicles, property, plants and all surfaces not designated for treatment from the product, splash and wind drift. Use polyethylene or other proven protective material.

Do not apply to surfaces which are frozen, dirty or have standing water.

C2 Protector may be applied to existing, cured concrete of any age. New concrete should be cured for at least 28 days prior to application. Surfaces must be clean and structurally sound. Remove all foreign materials including bond breakers, curing agents, surface grease and oil, and construction debris using the appropriate C2 surface prep cleaner. Follow the appropriate cleaner with thorough water rinsing.

If a d-limonene based cleaner/stripper is used, clean treated surfaces with C2 Degrease and rinse thoroughly.

Application may begin as soon as prepared surfaces are dry.

Surface & Air Temperatures

Should be 4-38°C (40-100°F) during application. Avoid application on hot, windy days.

Spray equipment for application of the C2 Protector - Sealer

Preferred method of application is with a lowpressure (<50 psi), pump-up sprayer and a microfiber or synthetic lint-free mop. Fit sprayer with spray tip. Sprayers should be fitted with solvent-resistant hoses and gaskets to avoid discoloration. Do not atomize during application.

Storage & Handling

Store in a cool, dry place. Keep tightly closed when not dispensing. Do not alter or mix with other chemicals. Always seal container after dispensing. Published shelf life assumes upright storage of factory-sealed containers in a dry place. Maintain temperatures of 4? 38° C (40 - 100° F). Do not double stack pallets. Dispose of unused product and container in accordance with local regulations.

Application of C2 Protector - Crete Colors Penetrating sealer

Read Preparation and the Safety Data Sheet before use.

ALWAYS TEST a small area of each surface to confirm suitability, coverage rate and desired results before beginning overall application. Test with the same equipment, recommended surface preparation and application procedures planned for general application. Let surface dry thoroughly before inspection.

Dilution & Mixing

Do not dilute or alter. Apply as packaged. Stir or mix well before use.

Typical Coverage Rates

Variations in concrete quality, porosity, job site conditions, temperature and relative humidity will affect coverage rates and drying times.

Estimated Coverage Rates

Steel Troweled Concrete:

37.75 m2 /L

1500 - 3000 ft2 / US gal

Mechanically Honed & Polished Concrete:

60 - 100 m2 /L

2500 - 4000 ft2 / US gal

C2 Seal or C2 Ultra Seal

Treated Concrete Floors:

100 - 120 m2 /L

4000 - 5000 ft2 / US gal

Applications to highly polished floors yield the highest coverage rates. Two thin applications achieve better results than one heavy coat.

Application Instructions

Horizontal Surfaces: C2 Protector may be applied to steel troweled, honed, polished or highly polished concrete surfaces. For best results, treat floors with C2 Super Hard, C2 Hard or C2 Hard Blend before application.

1. Lightly wet a clean microfiber pad with C2 Protector, leaving the pad damp.

2. Using a clean, pump-up sprayer, and working from one control joint to another, apply a light, fine spray to a small section of the floor.

3. Using the damp microfiber pad and firm downward pressure, immediately spread C2 Protector to produce a thin, even application. Spread the product as far as possible while maintaining a wet edge.

4. Allow to dry tack free, typically 60?90 minutes. Best results are achieved when C2 Protector is allowed to dry and cure for at least 4 hours prior to burnishing.

5. Once dry, C2 Protector may be burnished using a high-speed burnisher fitted with a C2 Heat Burnishing Pad or #1500?#3000 grit diamond polishing pad suitable for use on high-gloss finishes. In addition to smoothing and polishing the treated surface, high-speed burnishing can help to remove any surface haze from possible over application.

6. Repeat steps 1-5 above as necessary to provide additional stain protection. Apply up to two coats for maximum protection. Subsequent application or applications over surfaces treated with C2 Seal or C2 Ultra Seal will require less material and may take longer to dry.

Vertical Surfaces:

1. Apply uniformly with low-pressure, pump-up sprayer using enough product to saturate the surface.

2. Brush out heavy runs or drips thoroughly for uniform coverage.

3. An additional coat can be applied after material has dried for at least 60-90 minutes. The second coat will require less material.

Drying Time

Under typical conditions, treated surfaces are ready for foot traffic when dry to the touch. C2 Protector gains its stain resistance and water repellency after 24 hours. Stain resistance properties continue to improve for 7 days after application.

Cleanup

Before product dries, clean tools and equipment with mineral spirits or equivalent cleaning solvent. Immediately wipe off over- spray from glass, aluminum, or other surfaces.

Maintenance

Sweep treated surfaces daily with a microfiber pad or dry dust mop.

Remove spills or stains from surfaces treated with C2 Protector as soon as possible to minimize any potential for damage. Though C2 Protector will improve the resistance of concrete surfaces to staining, acid concentrates and acidic foods may etch the floor and leave a residual stain.

Use C2 Clean or C2 Maintenance for maintenance cleaning. C2 Maintenance contains lithium-silicate for improving surface density and preserving the surface sheen of C2 floors.

Do not use other cleaners, including off-the-shelf and common household cleaners, which may contain acidic or alkaline ingredients that can dull the finish of C2 floors.

To restore maximum water and stain protection to high traffic areas on vertical floors, repeat Application Instructions steps 1-5 in affected areas.

Best Practices

C2 Protector may be applied to steel troweled, honed, polished or highly polished concrete surfaces. C2 Protector can also be applied to surfaces previously treated with C2 Seal or C2 Ultra Seal. For best results, treat floors with C2 Hard, C2 Super Hard or C2 Hard Blend before application.

Variations in concrete quality, porosity, job site conditions, temperature and relative humidity will affect coverage rates and drying times. Over application can result in excessive darkening, extended drying times and significant surface haze.

ALWAYS TEST a representative area of each surface to confirm suitability, coverage rates and desired results before beginning overall application. Preferred method of application is low pressure pump-up spray equipment. Do not atomize during application. Use a fan-type spray tip and adjust pressure to prevent atomization.

Best results are obtained when C2 Protector is allowed to dry and cure for at least 4 hours prior to burnishing.

Use C2 Clean as part of a comprehensive floor maintenance program that includes deep cleaning with C2 Maintenance.
