  • For cracks greater than 1/16 inch, rout and caulk with a urethane sealant. Refer to SWRI Sealants – The Professionals’ Guide.
  • Apply Plastermix to concrete where a monolithic, void free texture is desired.
  • Apply Plastermix on reinforced concrete to increase carbonation resistance.

Priming

  • Priming is not necessary under normal circumstances.

Mixing

  • Stir or mechanically mix using a low speed drill (400 – 600) until homogenous.
  • Mix pails from different batches when an entire surface is visible.

Application

  • Apply a test sample to determine adhesion. Test using ASTM D3359 cross-hatch adhesion procedure.
  • Substrate temperature must be above 45°F.
  • Ambient temperature must be above 45°F for the entire curing period.
  • Roll, spray or brush apply a uniform 15 mils. wet – dries to 7 mils.
  • For roller applications use a 1 – 1-1/4 inch synthetic nap roller depending on texture of substrate.
  • For spray applications use a Graco 3500, President or Bulldog or equivalent with a 0.041 – 0.047 tip. Refer to Conproco Black Book.

An elastomeric coating uses acrylic chemistry modified to be flexible.  This flexibility allows the coating to stretch, bridging hairline cracks that are common in concrete and masonry surfaces.  Elastomeric coatings are typically applied at a higher mil thickness than most paints. 

Concrete, stucco, concrete masonry units and other masonry substrates are ridged by design.  Hairline cracks develop because of freeze/thaw cycles, movement caused by settling, and physical impact.   Once a crack develops water and environmental contaminants have a pathway which can lead to costly repairs.  The combination of a waterproof membrane with crack bridging capabilities is well suited to rigid structures.         

Lastic is available in 38 standard and unlimited custom colors.  Lastic is available in smooth and sanded finishes to accent architectural details.

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.

TWA Terminal

Project History

Eero Saarinen, an influential American architect was commissioned to design the TWA terminal in 1956. Along with the structural engineers Ammann & Whitney the “birdlike” structure was conceived as a complete environment. The architectural expression was intended to embody movement and transition. The construction of the terminal required a staff of 14 engineers and 150 craftsman. The selection of a shell-type structure offered the most dramatic architectural opportunities and made TWA stand out at the airport. For the concrete framework, steel-pipe scaffolding was erected on a grid, with each vertical accurately placed to support the underside of the form at the proper elevation and position. The terminal was closed in 2001 after TWA ceased to exist. DOCOMOMO-US, the Municipal Art Society of New York as well as the New York Landmarks Conservancy have been active in protecting the iconic structure. Today the beautifully restored terminal has reopened as a portal for Jet Blue Airways.

 

Harbor Towers 2008

Project History

The Harbor Towers were designed by architect I.M. Pei and constructed in the 1970s. In the mid 1990s the buildings had shown effects of their location in Boston Harbor.
Over a three-year period restorations and waterproofing to the building were made using Conpro Lastic. In 2008 the Towers were in need of a touch up, the appearance of the buildings was mottled and extremely dirty. These effects were again due to the constant ocean spray from the harbor coupled with the airborne particulate from the ten-year long “Big Dig”. Working with WJE, contractor NER Construction Management, Inc. found that the best solution was to prime the existing surface using Conproco Point 5 acrylic primer and recoat with Conpro Lastic elastomeric coating.
The building was power washed, primer was applied, followed by two 15-mil coats of Conpro Lastic. Conpro Lastic is a waterproof membrane, ideal for these high-rise buildings as it bridges minor cracking and performs well with the harsh conditions of the city and the driving rains of the North Atlantic.
