Gather your tools. Typical tools include a knife, sandpaper or a wire brush, gloves, and a damp cloth.
Be productive, be safe. Wear gloves and wash your hands after using epoxy putty.
Prepare your work area and materials. Make sure the relevant surfaces are clean (free of grease, dust, and oil) and dry. To improve adhesion, lightly roughen smooth surfaces using a wire brush or sandpaper.
Activate the epoxy putty. Knead the required amount of epoxy putty according to the manufacturer’s instructions.
Apply the putty as a filler. Apply your epoxy putty to the surface you want to repair within the amount of time specified in the manufacturer’s instructions. Work it into the crack or hole, and then shape or smooth it with your hands.
Apply the putty as an adhesive. If you want to use the epoxy putty for bonding, place the product between the relevant surfaces and apply strong pressure to ensure firm contact. When applying your product to wet surfaces, use force and hold the pieces in place until adhesion takes effect (see product details).
Create a nice finish. Rub the putty with a moist cloth before it hardens. Read the product details to find out how long you need to wait before you can sand, drill, or paint the epoxy putty.
Clean-up. Remove excess epoxy putty before it begins to harden. You can cut away cured and uncured putty with a sharp blade.
