| Surface Preparation
Proper surface preparation is essential to ensure coating success, performance, and longevity. In general, all surfaces must be clean, dry, undamaged, and free of contaminants prior to application.
STEEL
? Non-immersed surfaces: Abrasive blast to Sa2 in accordance with ISO 8501-1, achieving a surface profile of 50–100 µm.
?Immersed surfaces: Abrasive blast to Sa2½ (near-white metal finish) as per ISO 8501-1, with a surface profile of 50–100 µm.
Aged or previously coated steel: Abrasive blast to Sa3 according to ISO 8501-1, ensuring a surface profile of 50–100 µm.
Additional Instructions :
• Thoroughly remove all abrasive residues and dust from the prepared surface.
• Eliminate oil, grease, wax, and similar contaminants using S405 thinner (Epoxsol).
•Apply the coating system (EPX13) as soon as possible following surface preparation to prevent recontamination. Blasted steel must not be left exposed overnight.
•If immediate application of EPX13 is not feasible, a thin layer of EPX02 primer is strongly recommended as a temporary protective coating.
• Prior to the application of EPX13 over EPX02, ensure the primed surface is clean, completely dry, and free from oil, grease, or any other contaminants.
CONCRETE
?New concrete: Must be cured for at least 28 days at 21°C and 50% RH, or for an equivalent duration based on temperature and humidity.
EPX17 primer may be applied once the concrete has cured for at least 14 days at 21°C and 70% RH.
?Old concrete: Remove surface irregularities such as fins and protrusions by stoning, sanding, or grinding.
Abrasive blasting is the most effective method to remove previous coatings, form oils, laitance, and other foreign matter.
• Fill small holes and voids with STOP200 before applying EPX13.
• For highly porous concrete or poorly ventilated areas where solvent vapors are a concern, EPX17 is recommended as the primer.
If the surface has low absorption, EPX02 is a more suitable choice.
