Rust-oleum 9115402 Epoxy Mastic Coating 1 Gal Gloss Silver

Product Description

The RUST-OLEUM 9115402 is a single-component epoxy mastic coating formulated for direct-to-metal application on steel and concrete surfaces. It delivers a gloss silver finish with strong adhesion to properly prepared substrates without requiring a primer coat in most applications. Coverage runs 100 to 225 square feet per gallon depending on surface porosity and application method. The coating is rated for indoor use and carries a VOC content of 340 grams per liter. An activator is required for use and is sold separately. This product is typically specified and applied by industrial maintenance painters, commercial contractors, and experienced trade professionals handling rust-preventative coating work.

This epoxy mastic is designed for rust-preventative applications on steel and concrete in indoor industrial and commercial environments. It is suited for structural steel, equipment housings, tanks, and other metal surfaces where corrosion protection and a clean finish are required. The coating performs within an application temperature range of 50 degrees F to 120 degrees F. Compatible activators include part numbers 07836737, 00243543, 00243568, and 00243527, as specified by the manufacturer.

Installation Notes

Application should be performed by personnel familiar with industrial coating systems and applicable safety regulations. Ensure the substrate is clean, dry, and free of loose rust, oil, and mill scale before application. Do not apply below 50 degrees F or above 120 degrees F ambient temperature. Proper respirator and ventilation are required given the VOC content of 340 g/L — consult the product safety data sheet before use.
