KNOCKOUT Rust Converter & Primer



Packaging: Sold online in 1 quart container. Larger sizes (1 gallon, 5 gallon, and 55 gallon) available.

Coverage: Approx. 80-100 square feet per quart. 360-400 square feet per gallon.

Knockout safely converts rust back to black steel and leaves a primed, paintable surface.

Simply knock off any loose rust scale, wipe clean, and apply with a brush or roller. Knockout will be dry in minutes, forming a clear acrylic surface that can be painted or coated.

Knockout is recommended for use on wood deck fasteners prior to the application of Encore’s deck coating or other paint. It can also be used to protect house siding nails prior to painting, keeping rust bleed-through away.

Knockout’s unique formulation stays where you put it. Where other rust converters are water-thin and run, Knockout stays in place, even on vertical and overhead surfaces!

A Safe, Bold, New Standard In Rust Protection.

KnockOut lies beneath the painted surface, providing the protection you need.

KnockOut is setting a new standard in safe, water-based priming systems – even for the most demanding applications.

KnockOut can be applied with an airless sprayer, brushed, or rolled. Knockout is unlike other converter/primers because it’s thick enough to stay in place on vertical surfaces without sagging. It can be sprayed overhead and won’t drip.

KnockOut converts within seconds, dries within minutes, and can be top-coated with any paint or coating that is compatible with an acrylic film. Only one coat is required, which saves considerable time and material expense.

KnockOut has surpassed other types of converter/primer systems in ASTM and Petroleum Institute testing by as much as 10:1 in service life testing (salt fog chamber and salt-water submersion).

KnockOut is available in 55-gallon drums, 5-gallon drums, 1 gallon and 1 quart containers.

Applications include: Marine. bridges, ships, barges, offshore platforms, oil and gas pipelines, marina dry stack storage, steel sheet piling, aluminum sheet piling, etc. Inland. amusement parks, steel staircases, water towers, golf cart bridges, and countless other home and farm applications.

KnockOut is compatible with Encore products.
Knockout is perfect for treating nail heads on outdoor decking prior to applying Encore, Cool, RustOx, or other paint/coating product. Simply brush Knockout onto the fasteners or rusted steel and allow it to dry.
