DiamondFinish Clear

To achieve expert results, please take the time to carefully read and understand the following directions before you begin your restoration project. These directions are meant to be general guidelines only and do not cover every application or environmental situation. If you have remaining questions or concerns, please call us toll-free for technical assistance.

ALWAYS WEAR PROTECTIVE GLOVES AND SAFETY GLASSES. ALWAYS WORK IN A WELL-VENTILATED AREA. Please heed all labeled warning and caution notices on all products.


Theoretical coverage at one mil (25 µm) is 400 sq.ft. per gallon/9.8 m² per liter. Recommended thickness of two mils (50 µm) would require two full coats. Three coats recommended for marine applications. Material losses during mixing and application will vary and must be taken into consideration. Expect up to 50% less coverage on bare wood, rough or sandblasted surfaces.

Surface Preparation:

Clear Coating Over an Automotive-Type Base Coat:
Apply base coat as per manufacturers directions. Allow to dry which is normally about one hour.

Clear Coating Over Cured Coatings:
Clean surface with KBS Klean diluted 10 parts hot water to 1 part KBS Klean. Scuff with 600-1200 grit sandpaper and repeat cleaning process. Rinse & allow to thoroughly dry.

Clear Coating Bare Metals:
Metals should be freshly polished or sanded to the finish required.

For ferrous mateals, clean with KBS Klean at a dilution rate of 10 parts hot water to 1 part KBS Klean (10% strength) with the use of 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 minimizes any water stains.

For non-ferrous metals (aluminum, copper, brass, etc.), clean with KBS Klean at a dilution rate of 25 parts hot water to 1 part KBS Klean (4% strength) with the use of a very 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 minimizes any water stains.

Clear Coating Wood:
Wood surfaces should be smooth and dry with the wood having a low moisture content. All existing failed coatings should be removed, sand smooth and remove dust. Thin initial coat of DiamondFinish Clear 30-50% 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 as DiamondFinish Clear will tend to raise the wood grain with the first coat. Sand the surface smooth with fine grade of sand paper (280-320). Apply at least an additional full coat for general applications and at least a minimum of 3 coats for marine or industrial users.

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

Preparing For Application:

Ideal application temperatures are 50-82°F (15-28°C). Use only in moderate to dry atmospheric conditions Avoid rainy or high heat/humidity conditions.

DO NOT PAINT OUT OF CAN! Do not shake can. Stir thoroughly & frequently. Dispense a working amount of DiamondFinish Clear into a separate container (steel or glass is best) and seal original can immediately. 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 DiamondFinish Clear can permanently seal the lid. Unused paint should NEVER be put back into the can as it will shorten can shelf life and cause pressure build-up possibly popping the lid. If there is any trouble resealing the can lid tightly, transfer and store DiamondFinish Clear in a proportionally sized clean glass jar or new paint can. Always store in a cool dry place.

Applying DiamondFinish Clear (Non-Aerosol):

ALWAYS WORK IN A WELL VENTILATED AREA. Apply DiamondFinish Clear to clean and dry prepared surfaces using a bristle brush, foam brush, roller, or spray equipment. DiamondFinish Clear has superior self-leveling characteristics. Brush marks will flow out nicely. When brushing, apply covering coats, AVOID PUDDLING OR POOLING.

NOTE ABOUT BRUSHING: When brushing DiamondFinish Clear, apply thin, covering coats and do not overwork the brush as this can cause the DiamondFinish Clear to cure too quickly possibly leaving visible brush marks. It is best to brush an area with DiamondFinish Clear and move on immediately versus brushing an area over and over again. If you brush over an area over and over again forcing the solvents out, you run the risk of the brush marks not flowing out as well they are designed to flow out.

IF SPRAYING, ALWAYS WEAR AN AIR SUPPLIED RESPIRATOR AND EYE PROTECTION: NIOSH/MSHA approved organic vapor particulate respirator. Thinning is not generally required if brushing. When spraying, 10%-15% is normally adequate. DiamondFinish Clear can be thinned up to 30%. Use KBS #1 Thinner or Xylene ONLY.

When spraying: Spray pressure of 35-45 psi(250-330 kpa) for siphon/pot guns and 25-35psi (170-250 kpa) for gravity/top container guns. As a general rule of thumb, we recommend a 1.4-1.5 nozzle.

Always apply a MINIMUM of 2 covering coats, apply a thin covering initial coat followed by a moderate to full coat (2 mils each) for general applications.

For marine or industrial applications, apply a MINIMUM of 3 thin covering coats (2 mils each).

Re-coating can be done once the first or consecutive coat is dry-to-touch and does not leave a fingerprint which is usually within 2-4 hours. Remember to clean your spray gun immediately after using DiamondFinish Clear. FOR BEST END RESULTS, always apply coats consecutively within 6 hours of each coat curing. Average cure times are 1-2 hours, depending on humidity levels.

NOTE: Do not apply DiamondFinish Clear in wet or high humidity conditions to avoid rapid curing. Do not apply DiamondFinish Clear too heavy or too quickly between coats.

In each of these instances, surface bubbling may result as released carbon dioxide becomes entrapped beneath the top surface layer of paint.


NOTE ON DIAMONDFINISH CLEAR STORAGE: If storing for a period of time, hold can lid and plastic wrap (described above) closely above can and spray KBS Paint Saver towards side of the can to avoid splashing. Spray KBS Paint Saver two seconds for quarts or less and four seconds for gallons. KBS Paint Saver prevents oxygen and moisture damage and extends storage times of DiamondFinish Clear.

Applying DiamondFinish Clear (Aerosol):

FOR BEST END RESULTS. Apply DiamondFinish Clear to prepared surfaces as described above. ALWAYS WEAR PROTECTIVE GLOVES AND EYE WEAR when using DiamondFinish Clear. Always use NIOSH/MSHA approved air supplied respirator.

For best results, spray at room temperature 50° to 90°F (10° to 32°C). Use only in moderate to dry atmospheric conditions (i.e. 70% humidity or lower). Shake can for at least one minute after listening for rattle or mixing ball. During application, shake intermittently for approximately 10 seconds at 1 to 2 minute intervals. Press valve all the way down. Do not extend finger beyond the valve. Hold container about 8 to 10 inches from surface to be sprayed. Do not cover with continuous spray. Move back and forth, releasing sprayhead after stroke. Overlap each stroke. If clogging develops, turn sprayhead 1/4 turn or remove and clean sprayhead. Do not stick pin or other objects in to can opening. With sprayhead pointed away from you, reinsert sprayhead with gentle twisting motion.

IMPORTANT: Apply thin coats rather than heavy coats. If paint runs or sags, paint is being applied too heavily or paint can is too close to surface. Apply one or two thin covering coats for general automotive applications. For marine or industrial applications, apply a minimum of 2 - 3 thin covering coats. Recoating can be done once first or consecutive coat is dry-to-touch. For best results, always apply coats consecutively within 24 hours of each coat curing. Average recoat cure times are 1-2 hours depending on humidity levels. Full cure is usually achieved within 48 hours.

NOTE: Flow and gloss are increased with multiple coats. For maximum gloss, apply 4 passes, wait 10-15 minutes, then apply 4 more passes. To clear sprayhead for future use, turn can upside down and spray for 3 seconds.


Clean Up:

Use KBS #1 Thinner for immediate clean up including your spray gun.

IMPORTANT: Remember DiamondFinish Clear must be cleaned up before it dries. It cannot be removed by any solvent once cured. Always wear protective gloves to avoid skin contact and temporary staining. If skin contact accidentally occurs, immediately remove with #1 Thinner or lacquer thinner followed by soap and water. If DiamondFinish Clear should stain your skin, only the course of time will remove it.

DiamondFinish Clear - TIPS AND GUIDES:

  • If painting in conditions of high temperature and/or humidity, thin DiamondFinish Clear more than normal to avoid gassing.
  • Do not use UV or bake lights to cure DiamondFinish Clear.
  • DiamondFinish Clear will take 4 days to become hard under normal conditions and will continue to harden over the following weeks.
  • In spray booths, use low air flow and moderate temperatures for curing.
  • DiamondFinish Clear can be cut and polished as a normal clear coat after 24 hours under normal conditions.
