Product Information

Stop Flash Rusting Before It Starts!


Fiberlock IAQ 4000 is a rust inhibiting 100% acrylic latex metal coating for use on ferrous metal, galvanized metal and other surfaces exposed to general industrial and atmospheric conditions.


IAQ 4000 is ideal for both new and previously coated roof decks, metal paneling, structural steel, corrugated metal siding, and miscellaneous iron and bar joists.


Does not contain flammable solvents found in other rust inhibiting paints, has low odor and fast re-coatability.


Complies with the requirements for LEED® EQ Credit 4.2, low-emitting materials: paints and coatings.


Fiberlock IAQ 4000 has excellent water resistance and resistance to most alkalis, deter­gents and mild acids. This metal coating does not contain the flammable solvents contained in other rust inhibiting paints, has low odor and fast re-coatability.


Application Information


Remove all oil, grease, dirt, loose or scaling paint, rust, mil scale and other foreign matter. CLEAN ALL MOLD-INFESTED SURFACES WITH IAQ 2000 SERIES DISINFECTANT/CLEANER.


GALVANIZED METAL: Surface oil should be wiped off with mineral spirits and a clean rag.


PREVIOUSLY PAINTED SURFACES: Prepare ruptured or scratched surfaces as for unfinished metal. Spot prime bare ferrous metal as conditions dictate.


Apply Fiberlock IAQ 4000 with brush or roller. Spray application is not recommended because the mineral content is abrasive to spray equipment.
Brush: Nylon or polyester synthetic bristle
Roller: Synthetic fiber 3/8”nap or longer


Stir thoroughly with a lifting action to fully incorporate pigments. Fiberlock IAQ 4000 is supplied at application consistency, but can be thinned sparingly with water to improve application consistency if necessary. Apply with appropriate application equipment. Apply 2 coats of Fiberlock IAQ4000. Finish coat will seal spots of ‘flash rusting’ which may appear on ferrous metal after first coat.


Clean tools and drippings with warm soapy water before Fiberlock IAQ 4000 dries. Dispose of all waste according to all existing local, state and federal regulations.


Stir thoroughly. Do not mix with any other coatings, solvents or colors in oil. Do not apply Fiberlock IAQ 4000 when air or surface temperature is below 50°F or when drying conditions are poor. Keep from freezing. IAQ 4000 is not designed for tank interiors or immersion services.
