Application steps

APPLICATION INSTRUCTIONS

IMPORTANT

Strictly follow installation procedures

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

MIXING

  1. Mix Part A (resin) for ~30 seconds.
  2. Add Part B (hardener) to Part A.
  3. Mix continuously for 3 minutes, until a uniform mix is achieved.
    Note: Use a low speed electrical stirrer (300–400 rpm) to avoid air entrapment.
  4. During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing.

APPLICATION

IMPORTANT

Good ventilation

Always ensure good ventilation when applying the Product in a confined space.

IMPORTANT

Protect from moisture

After application, protect the Product from damp, condensation and direct water contact for at least 24 hours.

 

IMPORTANT

Substrate suitability

Do not apply the Product on gypsum plaster boards when used in wet areas such as shower rooms.

  1. Apply by brush, roller or airless spray.

CLEANING OF EQUIPMENT

Clean all tools with Water immediately after use. Hardened and/or cured material can only be removed mechanically.
