Rust-oleum 338806 Concrete Floor Primer 1 Gallon

Product Description

The RUST-OLEUM 338806 is a water-based concrete floor primer designed to prepare garage and interior concrete surfaces for topcoat paint systems. It penetrates bare or previously painted concrete to promote adhesion without the need for mechanical surface prep such as sanding or grinding. Licensed flooring contractors, painting professionals, and experienced DIYers apply this primer as the first step before applying floor enamels or epoxy-style topcoats. The water-based formula allows for easier cleanup and lower VOC output compared to solvent-based alternatives, making it practical for enclosed garage and basement environments.

This primer is suited for residential and light commercial garage floors, basement slabs, and other interior horizontal concrete surfaces. It is applied as a penetrating bonding coat before full floor coating systems. Each unit contains one gallon of primer concentrate, and packages are sold in quantities of two units per package. The no-sand, no-grind requirement makes it well-suited for maintenance recoats and light-prep new installations where the surface is structurally sound and free of contamination.

Installation Notes

Surface preparation, adhesion, and coating work of this type is typically performed by licensed painting contractors or flooring professionals familiar with concrete coating systems. Before application, ensure the concrete surface is clean, dry, and free of oil, grease, wax, and loose material. Allow the primer to fully cure per manufacturer guidelines before applying any topcoat. Work in adequately ventilated spaces and follow all applicable local codes for interior coating applications.
