Performance Characteristics

  • Versatile Experienced tradesmen can create a wide variety of textures and finishes.
  • Durable Resistant to weathering action, excellent freeze/thaw stability and abrasion resistance.
  • Breathability Allows moisture to diffuse, preventing damage from moisture build-up in wall system.
  • Integral color Color K-88 Admix added to gray or white Conpro Stucco (depending on color choice) provides long lasting color. *Note: Gallant Gray, Dickensian Gray and Navajo Brown require gray stucco.
  • Color choices Available in 14 standard earth tone colors.
  • Impact resistance Significantly more resilient than EIFS.

Surface Preparation

  • Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper bond.
  • Substrate should have open-pored and textured surface.

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 and 1 quart of K-88 Admix or Color K-88 Admix into a clean mixing vessel and slowly add all of the powder.
  • The proper mix ratio is 4 parts powder to 1 part water to ¼ part K-88 Admix.
  • 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 excess air.

Application

  • At the time of application, surfaces should be saturated surface dry (SSD) but hold no standing water.
  • Apply a key coat of Conpro Stucco, filling all voids.
  • Allow material to take up to thumb-print hard.
  • Trowel or spray texture coat.
  • Work to break points to avoid cold joints.

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.

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.

Best Suited: Balconies, walkways and slab -on-grade surfaces. Excellent for pedestrian and light vehicular traffic.

Super Color Stain: A penetrating opaque water-based stain that provides uniform color to concrete and masonry.
Best Suited: Apply to Elastideck in the same color to provide resistance to dirt pick up and staining.

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.

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.

 

Project History

Seneca Falls was named after a group of canals that run along side the Seneca River. Over the last decade, villages along the canals have been restoring historic structures, including the Arcade Building. The canal side concrete columns and beams had been deteriorated for many years. The contractor applied ECB, an anti-corrosion coating to the cleaned reinforced steel followed by a long open time bonding agent to the substrate. Multiple repair zones were prepared then overbuilt using Conpro Set, an overhead and vertical repair mortar. This was hand applied in several lifts and shaved to the original profile. A finish coat was applied to the entire surface for protection. The upper concrete beams had severe damage and the decision was made to encapsulate the substrate with Conpro One Coat, a stucco base that combines the scratch and brown coat in one application up to 1 – 2 inches thick, followed by a cementitious stucco finish. Conpro Shield W was applied to the entire structure to prevent water penetration.
