~ 45 minutes (at +23 °C)

12 - 18 hours (at +23 °C).

Open for foot traffic after 24 hours (at +23 °C).

Fully cured after 7 days (at +23 °C).

Sikagard®-180 must be applied in two layers. The coverage is approximately 0.20-0.40 kg/m² for each layer.

A total dry film thickness of minimum 400 microns is required to guarantee full perfomance of Sikagard®-180.

1 kg of mixed product will yield approx. 1.5 l of material. This amount will cover ~3.7 m² at a dry film thickness of 400 µm.

These consumptions are theoretical and can vary according to the absorption and roughness of the substrate. It is essential to carry out representative trials on site to evaluate the exact consumption.

Concrete / Mineral substrates

• The substrate must be sound and of sufficient compressive strength with a minimum pull-off strength of 1.5 MPa.

• 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 Sika products.

• All dust, loose, and friable material must be completely removed from the surface before application of the product, preferably by brush or vacuum cleaning.

Steel

• Remove all previous surface treatments and corrosion products by sand/shot blasting to SA 2½ finish or to bright metal finish.

• Application of Sikagard®-180 should be as soon as the steel is prepared to avoid surface rusting.

Sikagard®-180 is supplied in kits with the two parts in the correct mixing ratio. Material temperature should be preferably between +15 °C to +25 °C before mixing.

Add Part B into Part A without any remaining material in the pail. Ensure to scrape the sides of the containers to ensure a complete reaction. Mix properly for 3 minutes with a slow-speed drill and wing style mixing paddle at 300-400 rpm until a homogeneous colour is achieved. Keep the paddle below the surface to avoid entrapping air. Do not mix by hand!

Sikagard®-180 can be applied using short nap roller, shorthaired brushes or by airless spray. Apply in two coats, each at a wet fim thickness of 180 to 250 microns, the second coat applied cross-wise to the first coat after it has dried (after 12 - 18 hours at 23°C).

If the interval between layers exceeds 24 hours, the surface must be roughened before the application of the second coat.

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.

Clean all tools with a suitable solvent-based cleaner immediately after use. Hardened and/or cured material can only be removed mechanically.
