  • Substrate must be free of dirt, waxes, curing agents,and other foreign materials
  • High traffic applications should be sealed with a clearpolyurethane topcoat such as KEY #450 URETHANE
Application

Surface Preparation

Surface Preparation is the most critical portion to any successful resinous flooring system application. All substrates must be properly prepared as outlined in Key Resin Technical Bulletin #1. Work must be performed by trained or experienced contractors or maintenance personnel.

Mixing Instructions

KEY #805 is applied by roller, brush, or lambs wool applicator. Care should be taken to minimize the entrapment of air caused by over-rolling. Two coats are recommended for sealing applications.

Clean Up

Clean skin, tools, and equipment with soap and water.

Maintenance

After completing the application of KEY #805, the installer should provide the owner with maintenance instructions. KEY #805 is easily cleaned with neutral soaps or detergents.
