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.

INSTALLATION

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.
