Adhesion (Pull-Off)

Precondition both A and B components to a temperature of approximately 21 °C (70 °F) before use.

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 not exceed 4 % by mass (p.b.w. – part by weight) as measured with a Tramex® CM/E concrete moisture meter on a mechanically-prepared surface (mechanical preparation to ICRI / CSP 3 minimum).
• Do not apply to concrete substrate with moisture levels exceeding 4 % mass (p.b.w. – part by weight) as measured with the above mentioned equipment.
• If moisture content of concrete substrate exceeds 4 % by mass (p.b.w. – part by weight) as measured with Tramex® CM/E concrete moisture meter, contact your local Sika Representative.

2−3 hours when tested at 23 °C (73 °F) and 50 % RH

Refer to Sikalastic® Deck Coating Solutions guide for total system yield.

• Add entire contents of Comp. A into Comp. B.
• Mix components for a minimum of three (3) minutes, using a a slow-speed (400–600) rpm drill fitted with an Exomixer® or Jiffy type paddle suited to the volume of the mixing container..
• Scrape down sides and bottom of mixing vessel, then mix again for two (2) minutes.
• Keep the mixing paddle submerged during mixing to avoid entrapping air into the mixture.

Refer to Sikalastic® Deck Coating Solutions guide for total system and aggregate surface preparation and application. Sikalastic® P 255 is applied in conjunction with Sikalastic® M 265/ M 270 N base coat.
