About Flex-Mold

Flex-Mold is dedicated to developing products and methods for solving some of the problems associated with the tooling, production and repair of non-skid surfaces.

‘Gibco-Flexmold’ was invented by man with an idea, named Gibbs Slaughter Jr.  Gibbs was a proclaimed genius when it came to chemical and mechanical engineering, who luckily loved the boating world, giving us the gift of Flexmold non-skid patterns.

For over 30 years, we have successfully produced over 50 patterns for new installation and repairs. Our non-skid patterns are used by mold makers around the world to produce non-skid surfaces on fiberglass boat molds, fiberglass showers and tubs, waterpark decks, pools, wheelchair ramps, steps and other areas where a non-skid surface is desired. We also produce flexible molds designed for repairing existing non-skid patterns used on hundreds of production fiberglass and one-off boats.

Flex-Mold is the Pattern of Choice

Flex-Mold is the pattern of choice for many tool and production mold builders because:

  • The “limited slip” characteristics are good with shoes or bare feet
  • Flat-top design helps prevent wax buildup, unlike with sand or roll on patterns
  • Provides consistent pattern unlike spray or roll on applications
  • Clean-ability – ample spacing in pattern design limits particles getting trapped
  • Comfortable feel on bare feet and hands
  • Repair-ability in field
  • Appearance – over 50 patterns to select from
  • Ease of application to tooling
  • Use for mold maintenance and repairs
  • UL listed patterns available

We can assist your personnel in tooling applications and in factory repairs, and dealers with warranty repairs. Our objective is to help you solve some of your production problems so you can focus on selling your products.
