Application instruction
Surface preparation:
Pre-clean the steel if the surface has dirt, grease, or loose heavy rust scale.
Application:
Apply onto the surface to be treated with a brush or sprayer, or immerse the steel directly in the product for 15 - 30 minutes. Each subsequent coat should be applied 5 - 20 minutes after the previous one.
After 3 hours from application, the surface can be rinsed again with clean water and then concreted over, or the steel used as normal.
Notes:
Shake the product well before use.
Apply in dry conditions and avoid contact with water. Do not dilute the product with water.
If the steel surface contacts water during application, white particles may form on the steel, but this does not affect the properties of the steel.
Cleaning:
Clean equipment and tools with clean water immediately after application.
Safety guidance:
The product causes allergic reactions and skin corrosion. Wear gloves, a mask, and safety goggles when using the product.
In case of contact with eyes, nose, or mouth, rinse immediately with plenty of clean water several times before going to the nearest medical facility for timely and proper treatment.
