3.02 SURFACE PREPARATION

1. General: Perform surface preparation, including cleaning procedures, pursuant to coating manufacturer's published instructions and as specified for each particular substrate and coating condition.
   1. Remove all fixtures and other items not scheduled to receive coating, or provide surface-applied protection prior to surface preparation and coating application. Upon completion of coating work in each area, reinstall removed items.
   2. All surfaces must be sound and clean prior to coating system application. Remove dust, dirt, mildew, form oils, and similar surface contaminants.
   3. Completely remove existing painted surfaces exhibiting loose, flaking, or oxidized paint. Use sandblasting, waterblasting, electric sanding, or wire brushing for paint removal, and pursuant to coating manufacturer's published instructions.
   4. Fill large cracks, holes, and voids with an appropriate patching compound. Texture patched finish to match existing adjacent finish surface.
      1. For cracks less than 1/8 inch wide, cut out and fill with "Flex-Patch Patching Compound".

   6. Mask all adjacent areas not scheduled to receive coating system.
2. Interior Substrates:
   1. Remove all wallpaper paste residue, grease, tar, nicotine, and similar surface contaminants. Clean with TSP solution or acceptable equivalent. Thoroughly rinse.
   2. Remove and neutralize all mildew, fungus, and algae.
3. Exterior Substrates:
   1. Remove incompatible release agents, form oils, and all foreign matter.

3.03 MATERIAL PREPARATION

1. Mix and prepare coating system materials pursuant to coating manufacturer's published instructions.
2. Store materials not in actual use in tightly covered containers. Maintain containers used in storage, mixing, and application of coatings in a clean condition, free of foreign materials and residue. Do not store in sunlight. Do not allow to freeze.
3. Stir materials before application to produce a mixture of uniform density, and stir as required during application.

3.04 APPLICATION

1. General: Apply coating pursuant to coating manufacturer's published instructions. Use applicators and techniques best suited for substrate and type of material applied.
2. Base Coat: Over properly prepared substrates, including primer if required, apply base coat at the specified coverage rate.
   1. Coverage rate, interior substrates:
      150 to 250 sq. ft/gal.
   2. Coverage rate, exterior substrates:
      100 to 200 sq. ft/gal.
   3. Primer must cure pursuant to manufacturer's instructions under acceptable environmental conditions prior to base coat application.
   4. Thoroughly agitate base coat material prior to use. Do not thin.
   5. Apply base coat as a uniform pinhole-free continuous film over entire surface to receive coating system.
   6. Permit base coat to dry fully prior to splatter coat application.

   3. Flush equipment clean with water.
4. Lace Texture: Apply base coat and finish coat as specified. While finish coat is still wet, use knockdown tool over finish coat in a fashion to obtain desired lace texture. Use light pressure when knocking down finish.
5. Bark Texture: Apply base and finish coats as specified. While finish coat is still wet, roll over finish coat using light pressure.
6. Cypress Texture: Apply base and finish coats as specified. While finish coat is still wet, roll over finish using light pressure. Use knock down tool over rolled finish with very light pressure.
7. Optional Top Coats: Allow coating system, including texturing (if any), to cure for minimum 48 hours. Use of an optional finish topcoat must be indicated at the time of purchase for the MT/C Base and Finish Coats.
