Sikagard®-180

(former MProtect 180)

Epoxy-based two-part protective coating   

Sikagard®-180 is a non toxic, solvent-free, high build Epoxy based protective coating, especially developed to protect concrete and steel. 

  • Provides a glossy surface finish.
  • Forms a surface structure that prevents the formation of micro-organisms.
  • Easy to clean and creates hygienic environments.
  • Exhibits high mechanical strength.
  • Demonstrates superior chemical resistance compared to standard epoxy coatings.
  • Applies easily using brush, roller, or spraying methods.
  • Ensures water impermeability.
  • Solvent free.

Consumption

The coverage is approximately 0.30-0.60 kg/m²/coat.

The dry film thickness (DFT) is around 400 microns.
Application steps

SUBSTRATE QUALITY

  • The concrete substrate must be at least 28 days old, 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.
  • Steel surfaces have to be cleaned of all kinds of oil, grease, and rust traces that can weaken adherence, and a suitable surface has to be obtained by sandblasting to SA 2 ½.

SUBSTRATE PREPARATION

  • 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.
  • Steel surface need to be sandblasted to SA 2 ½, where can not be sandblasted, cleaning must be made by an air scraper gun or dish wire brush. When the surface is greasy and oily, oil removers are used. Right after the cleaning, Sikagard®-180 must be applied. The corrosion of the surface has to be prevented.

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.
