Surface Preparation:

Clear Coating Over an Automotive Base Coat

Apply base coat as per the manufacturer's directions. Allow to dry, which is normally about one hour.

Note: If the surface being clear coated will be consistently exposed to sunlight, be sure your automotive base coat is UV stable.

Clear Coating Over Cured Coatings

Clean the surface with KBS Klean diluted 10 parts hot water to 1 part KBS Klean. If needed, scuff with 600-1200 grit sandpaper and repeat the cleaning process. Rinse and allow to thoroughly dry.

Note: If the surface being clear coated will be consistently exposed to sunlight, be sure your base coat is UV stable.

Clear Coating Bare Metals

For ferrous metals, clean with KBS Klean at a dilution rate of 10 parts hot water to 1 part KBS Klean (10% strength) using a soft non-abrasive cleaning pad. Rinse the KBS Klean solution immediately, making sure you do not let it sit on the surface and dry in a way that leaves water stains.

For aluminum, clean with KBS Klean at a dilution rate of 25 parts hot water to 1 part KBS Klean (4% strength) using a very soft non-abrasive cleaning pad. Wipe the surface and do not soak. Rinse the KBS Klean solution immediately, making sure you do not let it sit on the surface and dry in a way that leaves water stains.

Clear Coating Wood

Wood surfaces should be smooth and dry with the wood having a low moisture content. Remove all existing failed coatings, sand smooth, and remove dust. Thin the initial coat of KBS MAXX Clear 30-50% with KBS #1 Thinner and apply a single covering coat to seal the wood. Allow to cure 24 hours. The wood will generally need to be sanded smooth again, since KBS MAXX Clear tends to raise the wood grain with the first coat. Sand the surface smooth with a fine grade of sandpaper (280-320). Apply at least one additional full coat for general applications, and a minimum of 3 coats for marine or industrial use.

Clear Coating Fiberglass or Carbon Fiber

Clean the surface with KBS Klean diluted 10 parts hot water to 1 part KBS Klean. Scuff with 600-1200 grit sandpaper and repeat the cleaning process. Rinse and allow to thoroughly dry.

Do not apply if the surface temperature is below 45°F or above 110°F, or if the surface temperature is within 5°F of the dew point. Always clean the surface well with KBS Klean. The surface should be free of all grease, dirt, oil, rust, and foreign material that would be detrimental to proper adhesion and the desired performance of the coating system being applied.

Mixing and Mix Ratio:

Always mix KBS MAXX Clear Base thoroughly. Use of the KBS Hurricane Paint Mixer or a similar mechanical mixing blade attached to a variable speed drill is highly recommended.

After the KBS MAXX Clear Base has been mixed well and is smooth in consistency, in a mixing cup or container, carefully measure 3 parts mixed KBS MAXX Clear Base. Add 1 part MAXX Activator. Mix thoroughly, again using a mechanical mixer such as the KBS Hurricane Paint Mixer.

KBS MAXX Clear Base and MAXX Activator are pre-thinned and ready to brush, roll, or spray, but you can add KBS #1 Thinner or Xylene as needed at this point, then mix well again with a mechanical mixer.

Application Characteristics:

Mix Ratio: 3:1 (Base Component : Activator)

Reducer: Ready to apply. KBS #1 Thinner or Xylene may be added if needed.

Pot Life: Doubles in viscosity in 30 minutes.

Dry Times:

Touch: 30 minutes
Through Dry: 1 – 2 hours
Hard: 3 – 4 hours
Recoat: 30 minutes to 3 days

Force Cure: Allow 15 minutes to flash, then 20-30 minutes at 140°-180°F.

Full Cure: A function of time, temperature, and film build. This product will not reach full cure for 7 days.

Note: Testing performed at 77°F, 50% relative humidity.

Application:

For optimum results, KBS MAXX Clear can be applied by brush or roller, or with spray equipment such as conventional electrostatic, conventional suction spray gun, HVLP, air assisted airless, or airless.

Brush and Roll: Use a natural bristle brush or high-density foam roller and reduce or thin with KBS #1 Thinner or Xylene. When brushing KBS MAXX Clear, for best results do not overwork the brush, as this can cause the coating to cure too quickly and leave visible brush marks. It is best to brush an area and move on immediately rather than brushing an area over and over again. Reworking an area forces the solvents out and risks the brush marks not flowing out as designed.

Note: The above parameters are guidelines only. Customer-specific equipment may require a different setup.

Clean Up:

KBS #1 Thinner, Xylene, or lacquer thinner for cleanup. KBS MAXX Clear must be cleaned up immediately, before it dries. Once cured, KBS MAXX Clear cannot be removed by any solvent. Wear protective gloves to avoid skin contact.

Dry Time / Cure:

Air Dry: Curing is a function of time, temperature, and film build. Air dry in 30 minutes to touch, thorough dry in 1-2 hours, dry hard in 3-4 hours. Tested at 77°F, approximately 70% relative humidity.

Note: The above information is a guideline for our customers. The user must be aware of the cleaning, pretreatment, application, and testing requirements for their specific job.
