ALWAYS WEAR PROTECTIVE GLOVES AND SAFETY GLASSES when using KBS Coatings 3-STEP SYSTEM. Please heed all warning and caution notices on containers and cans.
KBS Coatings 3-STEP SYSTEM of RustSeal (a rust preventive coating), AquaKlean (an industrial strength water-based cleaner / degreaser) and RustBlast (a powerful rust remover / metal etch) is the most technologically advanced metal protection system in the world today! RustSeal is a single-component, ready-to-use, high-solid content rust preventive paint. These exceptional properties make RustSeal specifically formulated to stop and encapsulate existing rust and corrosion thus permanently protecting and sealing bare metal from moisture. RustSeal cures to a rock hard yet flexible watertight seal that won’t chip, blister or peel and endures the harshest weather conditions including moderate resistance to UV rays. Because RustSeal is moisture-cured, this superior coating is made even stronger by continued exposure to moisture. RustSeal is also highly resistant to some of the most aggressive chemicals such as acids, alkalis, salts, abrasive materials, fertilizers, coal dusts, solvents, oils, and other refined petroleum products. RustSeal is highly surface tolerant and capable of adhering to almost any prepared substrate. RustSeal is VOC Compliant and is the first moisture-cured high performance coating offered in the widest range (EIGHT) of rust preventive paint color options.
Despite what others may lead you to believe, it does not matter how good the rust prevention product is if the surface is not prepared properly. Organic and corrosion contamination will block and inhibit any coating from deeply penetrating and permanently adhering to the surface. Simply put…the cleaner the surface, the more effective RustBlast will work and the deeper RustSeal will penetrate into the pores and permanently seal and protect the surface.
FOR BEST END RESULTS, apply RustSeal to clean, dry, bare metals with good surface profiles such as rusted, sandblasted, porous and abraded textures it can “bite” into. Newly sandblasted metal surfaces usually require little preparation other than blowing off loose dust and are the ideal choice for direct RustSeal applications. For all other rusted metal surfaces, begin by removing any LOOSE & FLAKEY rust by sanding with 320 grit sandpaper, wire brushing and/or wire wheeling. RustSeal loves rusted surfaces, but in order for it to stick well it needs a solid surface profile to adhere to. It is also necessary to remove all surface contaminates including oil, grease & road film which can interfere with RustSeal’s ability to seep deep down into the pores of the metal. For this reason, it is highly recommended that you use AquaKlean, a heavy-duty water-based cleaner/degreaser, which will rinse clean without leaving surface residue. AVOID any solvent-based cleaners which will also leave an invisible residue and affect RustSeal’s adhesion.
AquaKlean should always be diluted with water. The warmer the water used, the more effective and powerful the cleaning action of AquaKlean. Effective dilution rates will vary according to the type and degree of contaminants as well as surface materials. AquaKlean may be used in power washing equipment.
For general purpose cleaning, apply liberally and wash surface for 5-10 minutes. For heavy-duty cleaning, extended soaking times up to 24 hours or more may be necessary. Use a bristle brush or scouring pad to expedite the cleaning of heavily soiled surfaces. Retreat surface as necessary until clean. DO NOT ALLOW AQUAKLEAN TO DRY before rinsing. Rinse thoroughly with water after cleaning and then let dry. NOTE: Metal surfaces cleaned with AquaKlean should always be treated with RustBlast before painting to ensure proper adhesion.
NOTE: For all alloys and non-ferrous metals, AquaKlean application times and dilution rates should be kept to a MINIMUM due to the wide variations in these materials. For maximum performance, follow with RustBlast to remove surface rust, etch the metal, and leave a zinc phosphate coating (a white powdery film) for superior RustSeal adhesion. For all smooth or shiny metal surfaces, we recommend a light scuffing with 400 grit sandpaper followed by AquaKlean and RustBlast systems. For previously painted surfaces, remove all paint via chemical stripping followed by AquaKlean and RustBlast systems. If unable to remove any or all paint from metal surfaces, lightly scuff with 400 grit sandpaper followed by AquaKlean.
NOTE: If RustSeal is applied over an existing painted coating and not bare metal, it may not permanently seal rust but it will provide a durable, moisture-resistant coating.
Ideal working temperature 55-80˚F (13-27˚C). Surface to be treated should be free of dirt, oil, grease and other contaminants. The cleaner the surface, the more effective RustBlast will work. Scrape off any loose rust, mill scale, paint, etc. and clean with a water-based cleaner/degreaser. FOR END BEST RESULTS, use AquaKlean. Avoid any solvent-based cleaners as they will leave an invisible residue. Liberally apply RustBlast FULL-STRENGTH TO A DRY SURFACE using a spray bottle, brush, roller, or backpack sprayer for larger applications. Re-apply often and as needed to keep the surface wet for a minimum of 10 minutes for smooth or lightly rusted surfaces, 20-40 minutes for moderately rusted surfaces and 1-2 hours for heavily rusted or corroded surfaces. Do NOT allow surface to dry. After treatment, rinse thoroughly with water and then allow surface to dry completely. For removal of light corrosion or etching of non-ferrous metals (such as aluminium, brass, copper), prepare surface as above and apply RustBlast for 10-20 minutes then rinse thoroughly with water and then allow surface to dry completely.
NOTE: After treatment with RustBlast, there may appear a slight powder residue which is the zinc phosphate coating. Items treated with RustBlast can remain uncoated for up to 30 days depending on environmental conditions.
Ideal RustSeal application temperatures are 55º-82ºF (13º-28ºC). Use only in moderate to dry atmospheric conditions. AVOID applying RustSeal in extreme humid conditions because it is impossible to keep the metal dry and bubbling and improper adhesion may occur. Along with that, brush marks will not flow out. Always work in a well ventilated area. Remember to always wear protective gloves to avoid skin contact and temporary staining. RustSeal must be cleaned up before it dries. It cannot be removed by any solvent once cured.
DO NOT SHAKE CAN! Shaking will introduce air bubbles. STIR contents thoroughly for at least 3-5 minutes and often during the course of your painting project to make sure the pigments stay well-dispersed.
DO NOT PAINT OUT OF CAN! Dispense a working amount of RustSeal into a separate container (steel or glass is best) and seal can immediately. Unused paint should NEVER be put back into the can as it will shorten its shelf life and cause pressure build-up possibly popping the lid. Keep can groove free of paint by using a scoop or KBS Paint Spout. Use plastic wrap between the lid and the top of the can to stop metal to metal contact as RustSeal is extremely strong and tough and can permanently seal the lid. You may store RustSeal in a clean glass jar if you have trouble resealing the can lid tightly. Store in a cool dry place.
Apply RustSeal to clean & dry prepared surfaces by brush, roller, or spray equipment. Brush marks will level out as if sprayed. IF SPRAYING, ALWAYS WEAR AN AIR SUPPLIED RESPIRATOR: NIOSH/MSHA approved organic vapor particulate respirator. Spray pressure of 35-45 psi (250-330kpa) for siphon/pot guns and 25-35psi (170-250kpa) for gravity/top container guns. Thinning is not generally required, but if needed 5%-10% is normally adequate. Use KBS #1 Thinner only.
Always apply a MINIMUM of 2 thin covering coats (2 mils each) for general applications. For marine or industrial applications, apply a minimum of 3 thin covering coats (2 mils each). Recoating can be done once the first or consecutive coat is dry-to-touch and does not leave a fingerprint. FOR BEST END RESULTS, always apply coats consecutively within 6 hours of each coat curing. Average cure times are 2-4 hours, depending on humidity levels. NOTE: The more humidity or moisture in the air, the quicker RustSeal will dry. Applying RustSeal too thick or too quick between coats may cause surface bubbling. When RustSeal cures, Carbon Dioxide is released. Bubbling occurs when Carbon Dioxide becomes entrapped.
In areas not exposed to direct UV light, RustSeal will seal and encapsulate just like a topcoat. Although RustSeal exhibits moderate UV stability, continual exposure to UV light will cause RustSeal to become cosmetically altered or discolored but your rust protection will remain intact and not be destroyed. To protect against fading, you can topcoat RustSeal with any opaque paint system. Please note that a clear topcoat will not provide UV protection. KBS BlackTop is recommended for all Chassis applications. BlackTop is a high performance protective coating like RustSeal. When used as a topcoat over RustSeal, BlackTop produces an incredibly tough and professional looking finish.
To topcoat freshly painted RustSeal surfaces (less than 4 days old), apply BlackTop directly as no other prep is required. For all other applications, lightly sand with 320 grit sandpaper or spray with KBS Fusion Self-Etching Primer to promote good adhesion between the coatings.
KBS #1 Thinner is ideal for clean up. IMPORTANT: RustSeal must be cleaned up before it dries. It cannot be removed by any solvent once cured. Remember to always wear protective gloves to avoid skin contact and temporary staining. If skin contact accidentally occurs, immediately remove with KBS #1 Thinner followed by soap and water.
