SikaWall®-20 Surface Stabilizer WB

Base coat adhesion promoter to chalky vertical substrates.

A water-based, environmentally friendly surface stabilizer. Light brown in color to facilitate uniform application by brush or roller.

  • Conditions the surface and improves the bond of the EIFS or base coat/mesh surfacing system to the surface.
  • Acrylic polymer dispersion enhances surface penetration and promotes adhesion.
  • Safe water-based and non-toxic. Cleans up easily with soap and water.

Usage

Prepare chalky, previously painted masonry surfaces and sound-glazed brick or tile that will be renovated using an adhesively attached EIFS or base coat/mesh surfacing system.   

Advantages

  • Conditions the surface and improves the bond of the EIFS or base coat/mesh surfacing system to the surface.
  • Acrylic polymer dispersion enhances surface penetration and promotes adhesion.
  • Safe water-based and non-toxic. Cleans up easily with soap and water.

Product Details

Product Information

Shelf Life

One (1) year, when properly stored in the original container.

Storage Conditions

  • Store in a cool, dry place protected from freezing, extreme heat and direct sun. Store at no less than 40°F (4.5°C).
  • Do not stack pallets.

Volatile organic compound (VOC) content

ASTM D3960 (based in part on EPA Method 24)

<100 g/l, or 0.83 lbs/gal less water and exempt solvents

Application

Application Information

Ambient Air Temperature

  • When temperatures less than 40°F (4.5°C) prevail, provide supplementary heat during installation and drying period for at least 24 hours after installation and until dry.
  • Do not apply in ambient temperature above 100°F (38°C) or surface temperature above 120°F (49°C).

Substrates

  • Previously Painted Masonry
  • Sound Glazed Brick or Tile

Drying Time

Under average conditions [70°F (21°C), 50% Relative Humidity

  • Approximately 6-8 hours. Drying time is dependent on humidity, air temperature, sun exposure, surface conditions and finish thickness. Lower temperature, higher humidity and application in shaded areas will extend drying time.
  • Protect the surface from rain or other precipitation and temperatures less than 40°F (4.5°C) for a minimum of 12 hours and until dry.
Consumption

Coverage

800-1200 ft2 (74-111 m2) per pail

Coverage rates vary depending on the porosity of substrates and application techniques.
