How Much Pettit Black Widow Do I Need for My Boat?

Refer to the chart below to calculate how much Black Widow paint you will need for your boat.

1. Calculate the square footage of the hull to be painted - multiply the length of the hull by the beam then multiply that total by .85
2. Divide that number (your square foot total) by the amount of coverage Black Widow provides. (440 square foot per gallon). This will give you a one-coat total.

Example: If your boat has a length of 28', and a beam of 8.5', you will multiply 28 x 8.5 x .85 to get your total square footage. The total square footage for this boat is 202.3 square feet. A gallon of Black Widow has a coverage of 440 square feet per gallon for one coat, so one gallon will be enough for two coats.

How to Apply Pettit Black Widow Hard Racing Bottom Paint

Pettit Black Widow Bottom Paint is easily applied by brush, roller, or spray. When rolling, only use a high-quality short nap (3/16" maximum) roller cover. Mix paint thoroughly prior to application to ensure ingredients are evenly dispersed throughout the can. All surfaces must be clean, dry, and properly prepared prior to painting. Do not apply Black Widow directly on aluminum hulls or outdrives without properly priming first. When spraying, do not thin Black Widow more that 5% or inadequate film thickness will occur.

Burnishing of Black Widow to create a slicker finish can be done with 400 - 1200 grit wet or dry sandpaper after the coating has dried for at least 48 hours to achieve a smooth but matte finish. For a glossy finish, sand with 3000-5000 grit sandpaper. If burnishing, a third or fourth coat of Black Widow is recommended depending on application method.

• Application Method: Brush, roller, airless or conventional spray.
• Number of Coats: 1 minimum per season with additional coats for extended service
• Dry Film Thickness: 2 mils (3.6 wet mils)
• Coverage: 440 sq. ft/gal.
• Application Temp: 50°F Min. / 90°F Max.
• Thinner: 120 Brushing Thinner. 121 Spraying Thinner, or 120VOC Thinner
