Elongation

Precondition material to a temperature of approximately 21 °C (70 °F).

between +4 °C and +32 °C (40 °F / 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 / 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.

Sikalastic® M 200 cures in 12−14 hours when tested at 23 °C (73 °F) and 50% relative humidity.

Mix Sikalastic® M 200 to ensure uniform colour and consistency, 3 minutes at low-speed (300 to 450 rpm), using a drill fitted with an Exomixer® or Jiffy type paddle suited to the volume of the mixing container. Keep the mixing paddle immersed constantly in the material to avoid introducing or entrapping air while mixing.

Apply Sikalastic® M 200 at 25 wet mils thick (0.64 mm) using a proper notched squeegee to entire deck surface, and back roll, overcoating the properly prepared cracks, joints and flashings.

Do not coat expansion joints over 1" (25 mm) wide.

Slope grade product should be used on a slope greater than 15%.

Allow curing time of overnight (16-hour minimum). Extend the curing time in cool or dry weather conditions. The surface of Sikalastic® M 200 should have a slight tack. If the coating has been exposed for a prolonged period, consult Technical Service for recommendations.
