M3P-X

Performance Characteristics

• Anti-carbonation Reacts with calcium hydroxide at surface, mitigating carbonation to n depth of penetration.
• Water repellent Siloxane component provides long-term protection from water and water borne contaminants.
• Non-film forming Will not peel, blister or flake.
• Breathability 97% vapor permeable.
• Stable Unaffected by UV. Fire resistant.
• Environmentally friendly Water based, low odor, low VOC.
• Ease of application Mix with M3P in various ratios to create a mineral stain effect.

Surface Preparation

• Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper penetration.
• Prepare surface to be sandpaper-like texture (CSP 3) by mechanical abrasion or water blasting. Refer to ICRI Surface Preparation Guide 03732 for information about Concrete Surface Profile (CSP).
• Surface must be dry and frost free.
• New concrete must cure at least 14 days before application.

Mixing

• Stir or mechanically mix using a low speed drill (400 – 600) until homogenous.
• Box mix pails from different batches when an entire surface is visible.
• For transparent finishes, mix with M3P in ratios of 1:1, 1:2, 1:3,  1:4, etc. The more M3P-X added, the greater transparency in the finish.
• Higher dilution rates require more frequent stirring, be sure to mix/stir often to maintain color consistency.

Application

• Two coats of M3P at selected dilution is required to achieve best results.
• Apply a test sample to determine suitability. Ensure by visual inspection that M3P has penetrated the substrate. Surface must be absorptive for M3P application to be successful.
• Ambient temperature must be above 45°F for the entire curing period.
• For roller applications use a 3/8 – 1/2-inch synthetic nap roller depending on texture of substrate.
• For spray applications use an airless sprayer with a 0.017 – 0.021 tip.
• Work to pre-determined break points in the structure. DO NOT CUT IN!
• Maintain a wet edge while working to each architectural break point.
• A second application of M3P can be applied after the first is dry-to-touch.

Curing

• Protect from moisture for 24-48 hours.

Clean Up

• Clean tools and equipment with water. Clean adjacent areas with water before material dries.

Coverage/Yield

• Coverage rates vary considerably from substrate to substrate for all potassium silicate coatings due to surface texture and absorption rates of the masonry being coated. Apply a mockup to determine coverage rates for specific project.
• M3P-X – 150 – 300 ft²/gal.

Product Handling

• Packaging 5 gallon containers. 45 lbs. per unit 1 gallon containers. 9 lbs. per unit
• Shelf Life 18 months in unopened containers.
• Storage Protect from freezing. Transport and store in cool, clean, dry conditions in unopened containers. High temperature will reduce shelf life.

Limitations

• Do not apply if precipitation is forecast within 24 hours of application.
• Do not apply in strong  winds.
• Do not apply to frozen surfaces.
• Do not apply if temperature of substrate is below 45°F.
• Do not apply if ambient temperature is below 45°F. Ambient temperature must stay above 45°F during curing period.

Health and Safety

• Product is alkaline.
• Do not ingest.
• Avoid contact with skin and eyes.
• Refer to Safety Data Sheet (SDS) for additional information.

First Aid

• In case of skin contact, wash thoroughly with soap and water.
• For eye contact, flush immediately with a high volume of water for at least 15 minutes and contact a medical professional.
• For respiratory problems, remove person to fresh air.
• If respiratory difficulty persists, contact a medical professional.

Disposal

• Dispose of material in accordance with local, state and federal regulations.
