25 mil w.f.t (0.64 mm)

Between 4 °C and 32 °C (40 °F and 90 °F).

Substrate temperature must be at least 3 °C (5.5 °F) above measured dew point temperature.

Between 4 °C and 32 °C (40 °F and 90 °F).

Moisture content of concrete substrate must be ≤ 4 % by mass (part by weight) as measured with a Tramex®CME / CMExpert type concrete moisture meter on mechanically-prepared surface according to this product data sheet. Do not apply to concrete substrate with moisture levels exceeding 4 % mass (part by weight) as measured with Tramex® CME / CMExpert type concrete moisture meter. If moisture content of concrete substrate exceeds 4 % by mass (part by weight) as measured with Tramex® CME / CMExpert type concrete moisture meter, contact Sika Canada Inc.

20 minutes ± 5 ( at 21 °C (70 °F) and 50 % R.H)

Once the material has been mixed, the coating must be poured onto the surface and applied immediately.

3−4 hours*

*When tested at 73 °F (23 °C) and 50 % relative humidity.

Approx. 1.35–1.47 m²/L (55–60 ft²/US gal)

Concrete must be fully cured (28 days), structurally sound, clean and dry (ASTM D4263). All concrete surfaces (new and old) must be shot blasted to remove previous coatings, laitance and all miscellaneous surface contamination and to provide profile for proper adhesion. Abrasive shot blasting must occur after concrete repair has taken place. Acid-etching is not permitted. Proper surface profile should be a minimum of ICRI CSP-3 (as prescribed in ICRI document 03732.)

The compressive strength of the concrete substrate should be at least 25 MPa (3625 psi) and at least 1.5 MPa (218 psi) in tension at the time of application. Consult Sikalastic® Deck Coating Solutions for detailed surface preparation.

Precondition A and B components to a temperature of approximately 21 °C (70 °F). Add entire contents of Part A into Part B. Mix both components with a slow-speed drill (400–600 rpm), for a minimum of three (3) minutes. Scrape down sides and bottom of mixing vessel, then mix again for two (2) additional minutes. Keep the mixing paddle submerged in material during mixing to avoid air entrapment into the mixture.

Apply Sikalastic® M 270 NP at 25 mil w.f.t (0.64 mm) using a properly notched squeegee at the rate of approximately 1.35–1.47 m²/L (55–60 ft²/US gal) and immediately back roll the surface. Sikalastic® M 270 NP is applied without primer but also can be used with primer applications per system application instructions. Refer to the applicable Sikalastic®Deck Coatings system data sheet for total system and aggregate surface preparation and application.

Remove liquid coating immediately with dry cloth. Once cured, coating can only be removed by mechanical means.
