Selection & Specification Data

Generic Type

Epoxy Polyamide


Solvent-free patching compound used for repairing pits, cracks and voids in steel, concrete, wood and other surfaces. Has the unique ability to be mixed, applied and cured underwater.


• Designed for underwater and other wet applications.
• Can be applied up to 2" in thickness.
• Self-priming on most surfaces and over most generic types of coatings.
• Rapid cure characteristics.
• VOC compliant to current AIM regulations.


Olive Green


Low Gloss




Epoxies, Polyurethanes if required.

Dry Film Thickness

1/8"-2" (3.1-50 mm) for most applications.
1/4" (6.4 mm) is practical maximum thickness for vertical and overhead applications.

Solids Content

By Volume: 99% ± 1

Theoretical Coverage Rate

1604 mil ft2 (24.5 m2/I at 25 microns). Allow for loss in mixing and application. Field experience has displayed a realistic coverage rate of 8 ft2/gallon (.2 m2/I). This figure accounts for actual losses and the fact that the product is frequently applied at higher dry film thicknesses.

Nominal VOC Values

As supplied: 0.00 Ibs/gal (0 g/I)

Dry Temperature Resistance

Continuous: 200°F (93°C)
Non-Continuous: 250°F (121°C)

Substrates & Surface Preparation


Remove all oil or grease from the surface with Carboline Surface Cleaner 3 in accordance with SSPC-SP1. Remove all dirt, loose paint, sparring concrete, rotted wood, marine growth and other contaminants by abrasive blasting or high pressure water blasting. Hand or power tool cleaning methods may be used, but are of limited benefit and are time consuming. Abrasive blasting can be done underwater as the initial air blast will clear a path through the water for the abrasive/air mixture. When working at the splash zone or in salt water, coat cleaned metal surfaces as soon as possible to minimize new corrosion.
