SHELF LIFE

Do not store product exposed to weather and sun. When kept in a cool, dry and protect area, sealed pail have a 12-months shelf life.


SURFACE PREPARATION
  • All surfaces must  be structurally sound, dry, clean and free from movement, oil, grease, wax, curing compounds, release agents and any other loose or contaminating material
  • Prior to application, remove all sharp protrusions, which may pierce the membrane
  • The external and internal corner are made to be arc.
         Internal corner: D≥ 50mm
         External corner: D≥ 10mm

APPLICATION GUIDANCE
  • LEVELING: Substrate should be smooth and firm.
  • CLEANING: No garbage, floating pulp on the substrate, keep it dry. Prime the concrete surface
  • FIRST COATING: The first layer should be very thin, covering the substrate is enough, less than 0.5mm thickness.
  • SECOND & THIRD COATING: Apply the second layer provided the first layer is cured. Coating direction is vertical to the first one and then the third layer`s direction is the same as the first one.

PRECAUTION
  • Second layer is the thickest one, the third one is very thin, just for leveling.
  • Interval time depends on the application site, but typically full drying time is about 20 hours.
  • Fiber reinforcing layer is necessary for inside corner internal corner, floor drain, pipe joints etc, the lap width should not be less than 100mm, extensive application after joints treatment.
  • Use PU out after opening, time within 8 hours. Long-term storage will cause the forming of a thin film on the surface. Remove this when application. Does not affect the performance of product.
