MIXING

Note: Both components must be heated up to +70 °C. The accuracy of mixing and dosage must be controlled regularly with the spray equipment. Thoroughly stir part B (Amine) using a drum stirrer until a uniform consistent colour is obtained.

APPLICATION

Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

Prior to application, confirm substrate moisture content, relative air humidity, dew point, substrate, air and product temperatures.

Reference must be made to the Sika Method Statement: Sikalastic®-8800.

CLEANING OF TOOLS

Clean all tools with Thinner C or Sika® Remover-208  immediately after use. The application equipment must cleaned and filled with Mesamoll. Hardened material can only be removed mechanically.
