What is NTF Rust Converter? NTF Rust Converter, a water-based primer, contains two active ingredients. The first ingredient, reacts with iron oxide (rust) and chemically converts it to iron a dark-colored stable material. The second active ingredient, is an organic polymer that provides a protective primer layer. The overall chemical reaction converts rust into a stable, black protective polymeric coating that serves as an excellent primer for both oil and epoxy based paints.
How is NTF Rust Converter different than a rust remover? Rather than removing rust, a NTF Rust Converter mixes chemically with rust to create a black inert substance that can be painted over, concealing the existence of any rust and preventing further corrosion.
What objects can I use NTF Rust Converter on? NTF Rust Converter can be used on any rusty iron or steel object. It can be used on vehicles, trailers, fences & gates, iron railings and staircases, sheet metal, cast iron, outsides of tanks, lawn equipment, mower decks, farm equipment, tractors to name just a few. It will not work on aluminum, copper, stainless steel or galvanized metal. As a general rule, NTF Rust Converter is a good solution to fixing rust on items you would consider painting.
How do I prepare the surface for application? Good surface preparation will enable the NTF Rust Converter to work effectively and leads to a high quality end result. You will want to remove large rust and scale particles with a stiff bristled brush, hammer or sandpaper. The object of this step is to get any loose or flaking rust off as it does not provide a stable surface. The point is not to remove all the rust (this defeats the purpose of NTF Rust Converter) as NTF Rust Converter chemically bonds to the rust and seals it in. NTF Rust Converter cannot penetrate grease or oil, so clean and degrease the surface first, then let it dry. This step ensures that other surface contaminants will not interfere with the reaction of the NTF Rust Converter on the rusted surface. If the surface is subject to salt water spray for deicing salts, rinse the surface thoroughly with water, and allow it to dry prior to applying NTF Rust Converter.
How is NTF Rust Converter applied? For best results, apply NTF Rust Converter with a brush or a roller. Use a brush for smaller applications and a roller for larger surfaces. It can also be sprayed on, but we recommend using an airless sprayer.
Can I apply NTF Rust Converter over non-rusted or painted surfaces? Yes, NTF Rust Converter will adhere to non-rusted or painted surfaces but it does not provide any additional rust prevention when used on these surfaces.
Should NTF Rust Converter be thinned? NTF Rust Converter should not be thinned and should be applied as it comes out of the bottle, after being properly shaken or stirred.
How much metal will one gallon cover? One gallon covers up to 500 square feet of rusted metal. Porous, textured and irregular surfaces will require a heavier application rate.
Can I apply a primer coat over NTF Rust Converter? Yes, an oil based primer may be applied over NTF Rust Converter, but is not required.
Is it necessary to paint over NTF Rust Converter? Although it’s not required, if your surface is exposed to the outdoor elements, we highly recommend applying two coats of a quality oil-based paint over NTF Rust Converter. It will definitely extend the protective qualities of the surface from adverse weather including rain, salt mist and direct sunlight.
What type of paint should I use to cover the NTF Rust Converter? Use oil based or epoxy paints to paint over NTF Rust Converter, do not use Latex or water based paints.
How many coats of NTF Rust Converter should I apply? Many applications require one coat. We suggest applying a second coat to assure complete coverage and conversion.
How long does it take NTF Rust Converter to dry? NTF Rust Converter will dry to the touch in approximately 20 minutes. Application of a second coating will ensure proper rust conversion. If possible, wait 24 hours before applying a second coat of NTF Rust Converter to allow for curing. If applying an oil-based top coat, wait 48 hours after the last coat to ensure it has proper time to cure.
How should I clean my application equipment after applying NTF Rust Converter? Simply use soap and water for clean-up!
Can I use NTF Rust Converter on my grill, cast iron wood stove, engine, boiler, or any other heated surface? No, NTF Rust Converter is not heat resistant and should not be used on any surface that will be heated.
Can NTF Rust Converter be used on galvanized steel? It’s only effective on the highly rusted areas where iron oxide (rust) is present, and will not bond effectively to the galvanized areas.
Can NTF Rust Converter be used inside a tank? No, we do not recommend using NTF Rust Converter inside a tank, but it is commonly used on the outside of large tanks.
What is the shelf life for NTF Rust Converter? NTF Rust Converter has a shelf life of 9 months. We rotate our stock frequently to assure that the freshest batches reach our customers.
At what temperature can I apply NTF Rust Converter? Apply product when the temperature is between 50 and 100 degrees F. It’s best to avoid applying NTF Rust Converter in direct sunlight or under very damp conditions. Do not apply if the surface temperature is below 50 degrees F.
Can I use leftover NTF Rust Converter after I’ve poured it out of the bottle? No, once it’s been exposed and used, it should not be returned to the bottle with any unused liquid.
What protective equipment is required? It’s recommended that either safety glasses or goggles be worn along with chemical resistant gloves as it may cause eye or skin irritation. It is mild, but like with all chemicals (paint included), we recommend exercising caution.
How should I dispose of any unused NTF Rust Converter? Contact your local regulatory agency to determine the proper method of disposal.
Is NTF Rust Converter harmful if ingested? Yes, NTF Rust Converter contains tannic acid and medical attention should be sought immediately if ingested.
Are vapors from NTF Rust Converter harmful? The vapors emitted from NTF Rust Converter are similar to latex paints and are not harmful, but it is recommended that it be applied only in well ventilated areas.
Is NTF Rust Converter approved by the FDA or USDA? No, NTF Rust Converter shouldn’t be placed in contact with foods or human water supply.
How does NTF Rust Converter need to be stored? It’s best to store NTF Rust Converter out of direct sunlight at room temperature. Do not allow to freeze and avoid temperatures above 100 degrees F.
Can I put a powder coat over NTF Rust Converter? We have not tested NTF Rust Converter using a powder coating. From our information, powder coating is not typically applied over a primer coating, but instead is applied over bare metal. We do not know how effective the powder coating would be in adhering to the NTF Rust Converter product, and it may start to flake off. We do not recommend using a powder coating over the NTF Rust Converter.
