Application Guidelines

1. Surface Preparation:

   • Ensure all surfaces are sound, clean, and free from dust, grease, and loose materials.

   • Remove any flaking or peeling paint.

   • Highly absorbent surfaces may require light dampening prior to application.

2. Application:

   • Stir the product thoroughly before use.

   • Apply one coat evenly using a roller or brush.

   • Do not dilute. Use straight from the tub.

   • Ensure full coverage; the blue tint helps identify missed spots.

   • Allow to dry completely before applying plaster, typically 6 hours at 20°C.

   • Do not apply to wet or very cold surfaces (below 5°C).

Health & Safety

• Use in well-ventilated areas.

• In case of skin or eye contact, rinse thoroughly with water.
