Surface Preparation
Conproco Impact Wall System- Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper bond.
- Repair spalled areas, static cracks and voids with Conpro Set or Conpro One Coat.
- Substrate should have open-pored and textured surface.
- Apply Conpro Start where a consolidant is of benefit.
- Saturate substrate with clean water, (saturated surface dry/SSD). Wall should be wet when Conpro One Coat is applied.
- For best results on concrete grind or abrasive blast (CSP 3). Refer to ICRI Surface Preparation Guide 03732 for information about Concrete Surface Preparation (CSP).
- Substrates must be structurally sound, sheathing must be firmly fastened and comply with all applicable building codes.
- Place building wrap or air barrier depending upon type of substrate.
Priming
- No priming is required under normal circumstances.
Mixing
- Mechanically mix using a low speed drill (400 – 600 rpm) and mixing paddle or mortar mixer.
- Pour 3.5 – 4 quarts of potable water into a clean mixing vessel to each 50 lb. bag of Conpro One Coat.
- Mix continuously for 3 minutes to a uniform, lump-free consistency.
- Add up to 2 pints of additional water if needed.
- Allow to “breathe” for 1 minute and remix for 1 minute. This will improve workability and open time.
- Do not over mix, as this will entrain air and cause damage to the glass fibers.
Application
Conproco Impact (direct applied to concrete and masonry)- At the time of application, surfaces should be saturated surface dry (SSD) but hold no standing water.
- Trowel or spray apply material to a uniform minimum of between 3/8 inch and a maximum 7/8 inch.
- Apply additional coat of 1/16 – 1/8 inch to achieve a level plane where desirable.
- Place trim accessories (expansion joints, corner bead, etc.) as specified.
- Mechanically fasten self-furring diamond mesh metal lath (complying with ASTM C841 and ASTM C847) within the confines of the panels created by the trim accessories. Make sure to overlap the flanges of the trim accessories.
- Trowel or spray apply material to a uniform minimum of 3/16 inch, to completely cover the lath.
- Apply additional material up to 1 inch thick for added impact resistance.
Curing
- Keep damp with a fine mist of water for 24 hours.
- Protect from direct sunlight, wind, rain and frost during curing period.
Clean Up
- Clean tools and equipment with water immediately after use.
- Cured material must be removed mechanically.

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.

One Coat is used with metal lath when the application is greater than 1/4". One Coat can be troweled or machine applied. Most carousel and rotor stator pumps are capable of spraying One Coat.
Maintaining existing concrete block, brick, stucco and concrete surfaces that are structurally sound but can be expensive to repair or repoint. A value engineered solution is to apply a monolithic stucco coating to protect from further degradation and improve physical appearance.

Bush Memorial Center

Project History
Bush Memorial Center is one of the finest examples of Greek Revival Architecture in the Country. It serves as an elegant, formal approach to the northern end of the historic Sage College Campus. It was originally designed by James Dakin in 1836 as the First Presbyterian Church. The firm, Architectural+, was selected to design the complete interior and exterior renovation. The existing stucco system had extensive cracking and was delaminating. Investigation of the structure determined that the entire stucco system which was applied directly to the multi-wythe brick walls, required replacement. Exterior restoration included replacing the deteriorated stucco system with a polymer-modified fiber reinforced base coat and a traditional cementitious stucco finish. The base coat varied from 1/2 – 1-1/2 inches in thickness. The contractor recreated the original profiles with the use of templates and imagination. The project received an Excellence in Historic Preservation Award from the Preservation League of New York State.

Danville State Hospital

Project History
Danville State Hospital was constructed in 1869. Dr. Thomas S. Kirkbride developed a building design for asylums which optimized light, ventilation, and each patient’s view. Danville’s main building consists of a central structure of exposed serpentine stone, with two primary wings constructed of stucco covered schist, all with brownstone accents. C & D Waterproofing stripped all areas of deteriorated and delaminated stucco back to the original substrate. Conpro One Coat was applied directly to the substrate, without the need for expanded wire mesh. Conpro One Coat may be applied in thicker lifts than traditional stucco, making it the ideal material to replace the original scratch and brown coats. A finish coat of Conpro Stucco was applied to provide a uniform finish. The stucco restoration was completed with two coats of an acrylic elastomeric paint. The brownstone accents were repaired with MIMIC, which was slightly overbuilt and then shaved to achieve the same surface texture as the original stone.
