Preparation & Application

All surfaces must be thoroughly cleaned to remove dirt, grease, mill scale, loose rust and any other contaminants that can reduce adhesion via SSPC-SP1 solvent cleaning with recommended surface preparation.

Ferrous Metal
SSPC-SP10 (NACE No.2) to obtain a 1.5-3 mil mil (37-75 micron) blast profile. Weld slag must be removed. Striping of properly prepared welds with primer by brush or spray is recommended.

Stainless Steel
Surface profile should be a dense angular 1-3 mils and is best achieved through abrasive blasting. Remove all contaminants that would interfere with the performance of stainless steel for the intended service such as, but not limited to, imbedded iron or chlorides.

Power mix components separately, then combine and mix to homogeneity. DO NOT MIX PARTIAL KITS. Requires short 15 minute sweat-in time.

May be thinned up to 20% (24 oz/gal) with Thinner 2. Use of thinners other than those supplied or approved by Carboline may adversely affect product performance and will void product warranty whether express or implied.
