APPLICATION AND USE
Preparation
PREVIOUSLY PAINTED SURFACES In Good Condition Consult the Antifouling Compatibility Chart and prepare the surface as required. Apply at least 2 coats of Fiberglass Bottomkote® NT. In Poor Condition Completely remove all old antifouling paint using Interstrip 299E for fiberglass and wood, and by sandblasting to near white metal for steel. Follow application systems below.
BARE FIBERGLASS It is essential to remove mold release wax and other contamination in order to ensure that the antifouling paint properly adheres to the substrate. Remove mold release wax using one of the following Interlux products, Fiberglass Surface Prep YMA601V or Fiberglass Solvent Wash 202 following the product label instructions. Fill any surface imperfections with Interlux Watertite YAV135 following the label instructions. After the surface has been properly cleaned, follow one of the application systems below.
BARE FIBERGLASS - NO SANDING SYSTEM Clean the surface with Fiberglass Surface Prep YMA601V. Consult the relevant technical datasheet for product directions. Ultimate No Sand System Apply one coat of Interlux Interprotect 2000E. Refer to the Ultimate No Sand System Technical Bulletin for more information. Simple No Sand System Apply 1 coat of No Sand Primer YPA200. Refer to the No Sand System Technical Bulletin for more information.
BARE FIBERGLASS - SANDING SYSTEM Clean the surface following the preparation procedure above. Sand entire surface well with 80 grade (grit) paper until flat matte finish is obtained. Remove sanding residue. Apply two coats of Fiberglass Bottomkote® NT allowing appropriate drying times.
BARE FIBERGLASS - BLISTER PREVENTION SYSTEM Apply the InterProtect system for the prevention of blisters. Contact the Interlux Technical Service Department at 1-800-468-7589 or visit yachtpaint.com for complete instructions on the application of The InterProtect System.
BARE WOOD Sand with 80 grade (grit) paper. Remove sanding residue. Apply the first coat of Fiberglass Bottomkote® NT thinned 10% with Special Thinner 216 or Brush-Ease 433. Fill seams with Interlux Seam Compound 30 (if necessary). Apply two or more coats of Fiberglass Bottomkote® NT unthinned, allowing for the appropriate dry times.
Method For use on fiberglass, wood or properly primed steel and lead. At least 2 coats should be applied. Do not apply when temperature is below 10°C/50°F.
