Description

Don't remove rust, convert rust. Corroseal rust converter is an elite, industrial strength product for all your marine, household, automotive, and industrial rust problems. Extend the life of your metal equipment by protecting it from rust and corrosion. Rust occurs naturally when the iron in steel oxidizes and returns to its original state, iron oxide. Through an innovative chemical conversion process, Corroseal Rust Converter converts rust (iron oxide) into a stable substance, magnetite. It also primes the surface with a high quality latex metal primer at the same time. Corroseal truly provides one step corrosion control. Corroseal is the best way to deal with rust because it is less expensive, less time consuming, and is much more environmentally friendly than sandblasting. Corroseal eliminates the need to sandblast rust by chemically converting rust from iron oxide to magnetite, a black and inert substance. Corroseal rust converter is your best rust treatment and corrosion control option because it meets all your metal surface preparation needs by converting the rust and priming the metal surface at the same time.

Description

The POR-15 3-Step System is designed to stop rust on metal surfaces and ensures the best results when applying POR-15 Rust Preventive Coating. The clear-cut process allows for the proper cleaning, prepping, and coating of metal to create a non-porous surface that seals and protects metal from water, chemicals, and salt, and other corrosive contaminants. The POR-15 Stop Rust Kit covers a 6 square foot area with two coats making it ideal for small projects like sub frames, axle replacements, control arms, brake shields, etc. Kit contains POR-15 Cleaner Degreaser, POR-15 Metal Prep, POR-15 Rust Preventive Coating, paint brushes, latex gloves, and detailed instructions. Basic directions: Gloves, eye protection, and a properly fitted respirator should be worn whenever handling these products. STEP 1. Remove loose rust with a wire brush. Apply POR-15 Cleaner Degreaser to the surface, keep wet 10-15 minutes then rinse thoroughly with water and allow the surface to dry. For areas with noticeable build up use a stiff brush to break up material and continue to keep wet with POR-15 Cleaner Degreaser. It is important not to allow the product to dry on the surface prior to rinsing with water. POR-15 Cleaner Degreaser is a heavy duty water soluble cleaner that may be used over metal, wood, fiberglass, vinyl and concrete. STEP 2. Apply POR-15 Metal Prep to the bare metal surface, keep wet 10-15 minutes then rinse thoroughly with water and allow the surface to dry. It is important not to allow POR-15 Metal Prep to dry on the surface prior to rinsing with water. Once dry the surface may show a flash rust or white powdery residue this is perfectly normal. POR-15 Metal Prep provides the best surface profile and greatly improves paint adhesion to any type of metal surface. STEP 3. Apply two thin covering coats of POR-15 Rust Preventive Coating. Apply the first coat to the properly prepared substrate with the supplied brush. Apply the second coat when the first coat is almost dry, slightly tacky to the touch. If POR-15 Rust Preventive Coating is applied too heavy, brush marks may result in the finish. Do not apply this product if the humidity is above 70%. If the humidity is too high POR-15 Rust Preventive Coating will surface dry too quickly which may result in small bubbles in the finish. POR-15 Rust Preventive Coating requires a top coat only if exposed to direct sunlight. For top coating use POR-15 Top Coat or our two part topcoat POR-15 2K Urethane.
