All surfaces to be coated should be clean, absolutely dry and oil or moisture free before painting application. Oil and grease should be removed by solvent cleaning.


Repair Cases : Corroded areas should be power tool cleaned to St3 or blast cleaned to Sa2 or better. Existing system should be dry and free from loose paint, salt, grease and other contaminants prior to overcoating.


New steel : Abrasive blasting to Sa 2½ (ISO 8501-1:2007). 990CT is also designed to apply on manually cleaned steel surface. However all damage of shopprimer and contamination from storage and fabrication should be thoroughly cleaned prior to final painting.


Maintenance : : Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to St 3 (ISO 8501-1:2007) (minor areas) or by abrasive blasting to min. Sa 2, preferably to Sa 2½ (ISO 8501-1:2007). Improved surface preparation will improve the performance of the product.


Concrete : The surface should be perfectly dry and clean before applying 990CT. Grease, Oil etc should be removed by solvent. If needed roughen the surface by acid etching. New concrete shoule be cured for minimum 2 months. Slip agent and other possible contaminants should be cleaned by detergent washing followed by high pressure hosing with fresh water. Remove scum layer and loose matter to a hard, rough and uniform surface, preferably by abrasive blasting, or any other mechanical treatment or acid etching
