- Extensive color spectrum 34 standard colors, plus Matrix colors and custom matching.
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 or repairs must cure a minimum of 7 days prior to application.
- Substrate must be absorptive for proper application.
Priming
- M3P is a self‐priming two coat system. Mockups will determine if chalking can occur as a result of an unusually high absorption rate of the substrate
Mixing
- Stir or mechanically mix using a low speed drill (400 ‐ 600) until homogenous. Product may settle during storage or shipping.
- Box mix pails from different batches when an entire surface is visible.
- For opaque finishes, no dilution is required.
- For transparent finishes, mix with M3P‐X 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 ‐ ½‐inch synthetic nap roller depending on texture of substrate.
- Brush or back roll into substrate for pinhole free, uniform coverage.
- 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 – 150 – 300 ft²/gal.

For Cement Based Materials
The gallons per minute volume of a rotor/stator pump is determined by the pump size (i.e. size 6 has a larger capacity than size 3). The pressure capacity of a pump is determined by the number of stages. Thicker materials and longer distances require higher pressure.

Mineral silicates chemically react with any substrate containing calcium hydroxide resulting in a surface that is will not peel or blister. Mineral silicates are highly vapor permeable finishes particularly suitable for concrete and masonry structures.
Mineral silicate technology is formulated to be used on concrete and masonry structures because it is highly permeable, durable, color fast, with a natural finish that does not look like paint. M3P is a self-priming system that protects concrete and masonry from water entry, carbonation and other environmental contaminants. M3P is a perfect choice when the goal is to preserve a natural appearance and provide a naturally organic matte finish.
M3P is a paint that can be diluted with M3P-X at various rates to change the opacity of the finish. At a dilution rate of 1:1 and higher M3P is a stain. As a stain, M3P is effective in blending color variations of the substrate to create a more uniform appearance.
Because of its chemistry it is important to perform color matching on the specific substrate that is to receive the product and at the specific dilution rate if any. Conproco maintains two color labs in the US, staffed by personnel who combined have over 100 years of color matching experience to help make the process as fast and foolproof as possible.

M3P: An inorganic mineral silicate based paint that provides long-term protection and water repellency without changing the natural appearance of the substrate.
Best Suited: Protection from water and carbonation for structures that are difficult to maintain or impractical to recoat in the future. Provides a natural “not painted” appearance. Use when the object is to blend the color of the substrate to be more uniform
M3P Overcoat: Highly breathable hybrid mineral silicate/acrylic coating for application over painted or unpainted surfaces providing a natural non-gloss finish.
Best Suited: Previously painted substrates, particularly silicone and elastomeric coatings which after multiple application reduce vapor transmission to low levels. On unpainted surfaces to preserve natural appearance while hiding significant color variations in the substrate.
Conpro Lastic: An elastomeric waterproof breathable membrane for vertical exterior surfaces.
Best Suited: Structures that require a membrane waterproofing treatment because of cracks, mortar joints, porosity and other physical characteristics that allow water, carbonation and other contaminants into the substrate.
Color Coat: A water-based acrylic coating for concrete and masonry substrates.
Best Suited: Ideal for weather protection of concrete and stucco. High vapor transmission makes this coating well suited for nosing and underside of balconies. Good performance to cost ratio.
Super Color Stain: A penetrating opaque water-based stain that provides uniform color to concrete and masonry.
Best Suited: Horizontal and vertical surfaces that require water repellency as well as uniform color.
TerraColor: Formulated to match colored glaze finishes.
Best Suited: Repairing and restoring terracotta and brick.

THINGS YOU SHOULD KNOW WHEN CHOOSING A COLOR AND COATING
The actual color of the coating and stain may vary from the color samples in this card.
Always order a wet sample to be applied to the intended substrate. Allow to cure for a minimum of 24 hours before evaluating.
Stains are generally used in a color similar to the substrate and tend to be more natural looking compared to paints.
Paints are generally used to change the color of the substrate.
Elastomeric coatings are used to waterproof substrates that have movement (cracking or when carbonation is a concern).
The curing rate will affect the final color of Conpro Stucco. Substrate absorption, temperature, wind, moisture and the changing angle of the sun or obstructions that block the sun while curing will contribute to color variation of cementitious coating.
Always apply a sample of the material to the structure to determine actual coverage and the degree of adhesion (ASTM D3359). Allow one week curing before conducting adhesion test.
Plastermix applied to concrete prior to a coating will dramatically improve the overall appearance by creating a uniform, bug-hole free surface.
Projects Showcase
Hersheypark Stadium
Project History
Opened in 1939, Hersheypark Stadium is the most prominent outdoor venue between Philadelphia and Pittsburgh. The stadium hosts very diverse events from concerts to rodeos to racing. It was important that the coating selected to refresh the appearance was respectful of the stadium’s architecture. Carbonation, a concern for any building, would be a particular concern for a venue hosting racing events. Having a low odor system was important for scheduled events. The coating also had to be highly vapor permeable, as the stadium has no roof and water intrusion was likely. Conproco’s mineral silicate system was a natural choice. Since this system does not peel, blister or flake, there was no concern that the thousands of fans streaming through the venue would abrade or damage the coating. The final result was a very natural, vibrant finish.

Old Montgomery Courthouse
Project History
The Old Court House in Montgomery County, Ohio, was completed in 1850. Since that time, 14 Presidents have visited the structure and used its classic front steps as a platform for addressing audiences. The courthouse underwent several renovations during the 1900s to accommodate the flow of legal traffic. These renovations had the unintended result of dulling the impact of the original architecture. In 2000, Montgomery County and the Montgomery County Historical Society partnered to restore the building, and establish it as a civic focal point, with a budget of 4.2 million dollars. The limestone exterior had to be repaired and finished with materials which would blend seamlessly with the existing stone. Matrix was used as a repair mortar, not only for its performance and workability, but because it could be color matched on site. M3P was used for the extensive cornice repairs on the gables. The ability of M3P Stain to blend with these large sections contributed greatly to the completion of the project.
