GRAY COAT

Gray Coat

Picture
Picture
GRAY COAT is a single component liquid applied, water based, waterproofing membrane. It uniquely combines the features of a sealer and an elastomeric waterproofing membrane. Its high solid and low viscosity make this material effective for waterproofing and sealing concrete, asphalt, wood, metal and other common surfaces.

​GRAY COAT is easy to apply and when cured, it provides a tough, highly flexible seamless membrane, with excellent adhesion to most substrates. When fully cured, it is highly resistant to water and salts.

Usage

GRAY COAT has been specifically formulated as a waterproofing membrane. It may be applied to all common surfaces and suitable for both new construction and restoration.
​
Typical applications include below grade foundation wall waterproofing, horizontal, sloped, and vertical surfaces such as:

  • Below grade walls
  • Mechanical rooms
  • Between slabs
  • Shower rooms
  • Planters
  • Reflection pools
  • Podium decks
  • Balconies
  • Reservoirs and tanks
  • Asphalt, tiles etc.

Surface Preparation

Substrate should be clean, sound, dry, and free of any contaminants which may affect the membrane during or after cure. The presence of small amount of moisture in the substrate (such as in concrete, not fully cured) will not be detrimental to the performance of GRAY COAT.

Application

  • GRAY COAT may be sprayed, brushed, or applied with a trowel. 

Curing & Drying

Allow the material to dry at air and surface temperature of 2°C (35°F) or higher. Curing times will be affected by relative humidity temperature and air flow. The following times are given for average conditions and standard thickness. Actual times may differ depending on specific conditions present on job at time of application.

  • Track free film                          2 to 5 hours
  • 60% cure                                  7 days
  • 90% cure                                  28 days

​It is recommended that GRAY COAT be allowed to air dry to a tack free, gray film before application of specified insulation, protection board or other cover.

Clean-up

Uncured material can be cleaned using light soap and water. Cured material is best removed by xylol or by mechanical means.
