Restrictions:
The packaging should not be opened until the components are used.

Surface Preparation:
Generally, coating performance and surface adhesion are directly proportional to surface preparation. Surfaces must be free of dust, oil, rust, corrosion, and other contaminants. The most common cause of surface coating problems is poor surface preparation. Surface preparation varies depending on the application. Therefore, the primer used on the surface will also vary. Primers may vary depending on both the surface and the product. To achieve optimal application efficiency, the recommended products and primers should be used.

New and Old Concrete:
For Jehoel polyurea to adhere well to the surface, the surface must be clean, dry, and sound. Dust, dirt, oil, mold release agents, curing agents, salts, and easily removable, weak particles should be removed using a milling machine, water jet, or sandblasting. If the old concrete surface is damaged and uneven, as well as has holes, cracks, or voids, it should be repaired by mixing sand into the epoxy-based primer.

Wood:
The surface must be dry and clean, and all freely removable parts must be removed. Splinters and excessively rough surfaces must be smoothed, and cracks must be repaired with a mixture of sand and a suitable primer. Polyurea Insulating Floor Coating

Steel (surface exposed to atmosphere and water):
Oil, grease, weld beads, and sharp edges must be removed from the surface. The surface should be prepared by sandblasting to international standards. The surface should be primed on the same day as sandblasting to prevent flash rust.

Aluminum:
The aluminum surface should be cleaned with aluminum oxide or sandblasted. Excessive sandblasting can damage the surface. After sandblasting, the surface should be cleaned again with a suitable aluminum cleaner. The surface should be dried and then primed.

Brass and Copper:
Brass and copper surfaces should be sandblasted. After sandblasting, a primer should be applied.

Galvanized Surface:
The surface should not be sandblasted. Oil and dirt should be removed with a suitable cleaner, and a primer should be applied. Polyurea Insulation Floor Coating

Glass Fiber Reinforced Plastic (Polyester):
The gel-coat layer should be lightly sanded or sanded with 80-grit sandpaper.

Plastic Foams:
Better adhesion is achieved when polyurethane and polystyrene foam surfaces are mechanically roughened. Primer can be applied if necessary.

Canvas-Fabric:
It can be applied directly onto many fabrics and fiber structures and does not require a primer.

Stainless steel:
Sandblasting is recommended after removing grease, oil, and other contaminants from stainless steel surfaces. Due to the structure of some stainless steel alloys, adhesion problems may occur. Preliminary testing is recommended. Polyurea Insulating Floor Coating

The shelf life of Polyurea A and B components is 6 months from the date of production as long as the packaging lids are not opened.
Barrels should be stored on wooden pallets and direct contact with the ground should be prevented.
Components A and B should be stored above 15 oC.
Precautions must be taken to prevent components from freezing.
