Sikagard®-180 KNS WB is a modified-acrylic-based liquid polymer.

15 months when properly stored

Store in unopened containers in a clean, dry area between 40°F and 85°F (4°C and 29°C). Keep from freezing.

Test results are averages obtained under laboratory conditions. Expect reasonable variations.

• Times are based upon temperatures of 65 to 85° F (18 to 29° C) and 50% relative humidity.
• Light foot traffic or between coats: 4 hours
• Normal traffic: overnight
• Maximum hardness: 7 days
• Material will take longer to dry at either higher humidity or lower temperatures.

Curing only:
200–400 ft² /gallon
(4.9–9.8 m² /L)

Second coat (dustproofing and sealing):
400–600 ft² /gallon
9.8–14.7 m² /L)

Recoating, dustproofing, and sealing:
200–300 ft² /gallon
(4.9 – 7.4 m² /L)

Coverage varies with the application method, texture, and porosity of the surface.

1. Freshly placed concrete must be properly finished. The surface is application ready when it is damp but not wet and when it cannot be marred by foot traffic.
2. Existing concrete surfaces should be thoroughly repaired and cleaned before application. Surface must be clean, dry and free of dust, oil, grease, sealers and all other surface contaminants that might inhibit proper bond of material.

1. Thoroughly mix material in original container before applying.
2. Apply a continuous, uniform film by lowpressure spray only, short-nap roller or lamb’s wool applicator.
3. For curing, one coat may be sufficient. However, two coats may be required in hot and windy conditions. Apply evenly and uniformly as soon as possible after final finishing.
4. To seal and dustproof, two coats are required. Apply the second coat when all trades have completed their work and site is ready for occupancy.
5. Do not overapply or soak concrete surfaces with the curing compound. Do not allow the curing compound to pool on the surface. Overapplication can result in alligatoring and mud cracking, whereby a film forms on the substrate before the material dries properly. Over- application may also cause opacity, as elements of the curing compound become trapped in the subsurface and cannot escape.

Clean tools immediately after use with soap and warm water.
