Surface preparation
Painted surfaces – These surfaces must be completely clean and free of any grease and other contaminants. Before painting, the surface should be completely dry and if a long time has passed since the application of the undercoat, a suitable roughness should be created by soft sanding on the surface. Steel surfaces – Wash the steel surface with a suitable solvent to remove grease, salt and any other contaminants. De-rust and create profiles on surfaces by various methods such as sand blasting up to 2.5 degrees Swedish or by mechanical tools up to ISO-ST3 degree. In metal structures and welded points and corners should be smooth and polished and free of any appendages and sharpness. After de-rusting and creating a profile, remove the particles from the preparation and other contaminants from the surface with a pressure of air free of moisture and grease and with the method of vacuum and thoroughly clean. Note that the application of the first layer (primer) should be done no later than two hours after preparation. Concrete surfaces – If the concrete is fresh, it must be 28 days after the concrete has been applied (the concrete surface is completely dry). If the concrete is old, the surface must be washed with fresh water to remove contaminants such as salts, grease, dust and Dust, loose and unstable particles, etc. from its surface
Description of Epoxy Putty
Its properties include:
- High hardness
- Good physical resistance
- Very good spatula
- Final and smooth surface
- Proper moisture resistance
- Excellent adhesion to concrete and primer surfaces
Uses
Due to the hardness and filling properties of this putty is very suitable for use in parts that are under high pressure. Its uses include:
- Industrial and health halls
- Warehouses
- Gym flooring
- Storage Silver
- Floors of control halls of refineries, power plants and chemical factories
- Parking lots

Surface preparation
Painted surfaces – These surfaces must be completely clean and free of any grease and other contaminants. Before painting the surface must be perfect
Dry and if a long time has passed since the application of the undercoat, a suitable roughness should be created by soft sanding on the surface. Steel surfaces – Wash the steel surface thoroughly to remove grease, salt and any other contaminants. De-ring and create Profiles on surfaces by various methods such as ballast document up to 2.5 SA Swedish or by mechanical tools up to ST3-ISO
(SP10-SSPC). In metal structures and welded points and corners should be smooth and polished and free of any appendages and sharpness. After de-rusting and creating the profile of the particles obtained from the preparation and other contaminants, remove the surface with moisture and grease free from moisture and grease by vacuum method. Note that the application of the first layer (primer) should be done no later than two hours after preparation.
Staining instructions
After preparing the surface and choosing the method of painting, first mix the fabric of the relevant solution with the recommended ratio and mix the mixture thoroughly to make it uniform. Add a special amount of ethyl silicate thinner if needed (usually not needed) (add to the mixture and stir until a primer is applied, then apply the paint with a suitable tool.
Storage and transportation
The above paint is flammable, so it should be sealed in a sealed container and kept away from moisture, fire, and strong currents of electricity and incendiary materials. It is recommended to consume the contents of the container as soon as possible after opening the lid. Suitable storage temperature is 20 degrees Celsius.
Safety
When applying paint, use safety equipment such as masks, glasses, robes and proper ventilation. In case of contact with skin, clean the area with a cloth soaked in a suitable condition and wash with plenty of lukewarm water and soap. Avoid breathing paint vapors, especially during application.
