Put epoxy putty to the test

Artificial Content Title -- to be hidden

You can use epoxy putties to perform many small repairs yourself and save time and money. A variety of specially formulated putties is available for a wide range of applications, from aluminum epoxy putty to waterproof epoxy putty. Read on to learn more about these unique adhesives.

What are epoxy putties?

The term “epoxy putty” refers to substances that harden at room temperature and are used as space-filling adhesives. Like other epoxies, they are stored as two separate components until use - Loctite Repair Putty All-Purpose is a good example of a premium two-part epoxy putty that will even bond to damp surfaces. Kneading the components together creates an exothermic chemical reaction that makes the substance usable for DIY purposes.

Epoxy putty uses

Unlike many other types of adhesive, epoxy putties fill gaps and can even be molded into structural parts. That means they are great for applications and three-dimensional repairs which other adhesives cannot handle. For instance, you can sculpt epoxy putties like modeling clay to reform missing parts or details, such as the corner of a cornice or small sections of ceramic tiles. Additionally, use epoxy putties for projects exposed to lots of moisture, like patching leaks, because these adhesives and bond to damp surfaces.

You can also use epoxy putties to anchor bolts in concrete walls. Note, however, that epoxy putties are intended for limited structural use, and many are designed for a specific application. When choosing your epoxy putty, you need to consider the intended use and the substrate to which your putty needs to bond. Different options include wood epoxy putty, marine epoxy putty, and quick steel epoxy putty. For example, steel epoxy putties are formulated to bond especially well with metal.

How to use epoxy putty

This section tells you how to use epoxy putties as fillers and adhesives.

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.
