How to

Step by Step Guide

1. Preparation - Metal Surfaces

Remove dirt, oil, grease, loose flaky rust, etc., with a suitable high pressure water cleaning system using LOCTITE SF 7840 cleaner/degreaser.

2. Preparation - Rubber Surfaces

Remove all loose and damaged pieces of material from the repair surface such as old rubber, fabric, etc. Abrade the repair area with an abrasive wheel, being sure to avoid overheating and melting of the rubber.

3. Mixing

A corded drill with mixer attachment can be used for mixing. Pre-mix the resin for 1 minute. Add the hardener into the resin and mix thoroughly until there is a uniform color and consistency. Be sure to scrape the sides and bottom of the pail.

4. Application

Apply a thin amount of the coating onto the repair area and work the product into the surface with a trowel, spatula, or gloved hand, to ensure good adhesion and to avoid bubbling. The coating can then be built up to the desired thickness required.

5. Clean-Up

Tools and other soiled areas can be cleaned up quickly and easily with LOCTITE SF 7617 Industrial Hand Wipes.
