Micro-Mesh® Urethane Coating Rectification Procedures

---

Micro-Mesh® is a unique cushioned abrasive that produces a very fine and uniform scratch pattern. The nine grits range from 1500 up to 12000. The 1500 is slightly coarser than common 600 grit sandpaper. The 12000 will leave a scratch pattern that cannot be detected by the human eye. Micro-Mesh can be used by hand or for a more aggressive result use with power tools. Micro-Mesh can be used both with or without water or lubricant. A lubricant will extend the life of the material. It is very important not to use Micro-Mesh with any type of solvent or alcohol based lubricants that would result in delamination of the Micro-Mesh.

Micro-Buff™ is an environmentally safe, water-based compound used for removing haze and swirl from coatings, composites and painted surfaces. Micro-Buff can be used by hand or for a more aggressive application use with power tools and a wool and foam polishing pad.

TufBuf™ lambs wool polishing pads are mode of the finest natural shearling hides available. The TufBuf is durable and washable. Its dense pile distributes and applies compounds evenly and consistently leaving your finishes with less haze and swirl than conventional polishing pads.

Please note: due to differences in paint types and conditions, not all of the steps set forth in these procedures may be necessary for you to attain the desired result. They should be used as guidelines to assist you in the development of your own specialized processes.

1. Repair of Urethane Coated Wood

Use Micro-Mesh 8000 by hand to remove scratches. Always sand in a straight line pattern making certain to completely cover the entire area being restored. If Micro-Mesh 8000 is not aggressive enough, go to Micro-Mesh 6000 followed by Micro-Mesh 8000. Be careful not to sand through the coating. With a slow 750-1000 rpm rotary polisher, polish the sanded area using a dime-size amount of Micro-Buff and a TufBuf lambs wool polishing pad. Wipe any residual Micro-Buff off with a soft cotton cloth.

2. Repair of Urethane Coated Composites

Use Micro-Mesh 8000 by hand to remove scratches. Always sand in a straight line pattern making certain to completely cover the entire area being restored. If Micro-Mesh 8000 is not aggressive enough, go to Micro-Mesh 6000, followed by Micro-Mesh 8000. Be careful not to sand through the coating. With a slow 750-1000 rpm right angle polisher, polish the sanded area using a dime-size amount of Micro-Buff and a TufBuf lambs wool polishing pad. Wipe any residual Micro-Buff off with a soft, cotton cloth.

3. Urethane Catalyzed Paint - Removing Damage from Uncured Paint

Using a mist of water on the Micro-Mesh and using very light pressure, begin with Micro-Mesh 3600 to remove defects, followed by 4000, 8000 and 12000 by hand. To polish, hand rub using Micro-Buff and a soft flannel cloth.

For any of the above procedures:

Rinse out the TufBuf lambs wool polishing pad and Micro-Mesh abrasives in mild detergent, dry and store for future use.
