Consumption

Consumption

Sikagard®-180 is recommended to be applied in two layers. The coverage is approximately 0.20-0.40 kg/m² for each layer. A dry film thickness of around 125 to 250 microns is sufficient for Sikagard®-180.
Application steps

SUBSTRATE PREPARATION

  • The substrate must be sound and of sufficient compressive strength with a minimum pull-off strength of 1.5 N/mm2.
  • The substrate must be clean, dry, and free of all contaminants such as dirt, oil, grease, coatings, and surface treatments, etc.
  • Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open-textured surface.
  • Weak concrete must be removed, and surface defects such as blowholes and voids must be fully exposed.
  • Repairs to the substrate, filling of blowholes/voids, and surface leveling must be carried out using appropriate products from the Sikafloor®, Sikadur®, and Sikagard® range of materials.
  • All dust, loose, and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.

MIXING

Sikagard®-180 has two parts in pails, produced according to the right mixing ratio. Material temperature should be between 15°C to 25°C before mixing. Part B should be added into Part A without any remaining material in the pail. It should be mixed using a proper mixer (~300rpm) for polymer mixing. Mix the parts for at least 3 to 5 minutes to have a homogenous mixture. After waiting for 3 to 5 minutes, the mixture is then mixed again for approximately 30 seconds and becomes ready to use.

APPLICATION

Sikagard®-180 can be applied using either a roller or a spray machine. It is recommended to apply the second layer before the first one is fully cured. If the interval between layers exceeds 24 hours, the surface must be roughened.

For re-coating due to damage or other reasons, prepare the surface by roughening it with a wire brush or emery paper to ensure adequate mechanical adhesion. Remove any damaged coating entirely, and apply the new coating as if it were the initial application."

CLEANING OF TOOLS

Clean all tools with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
