Q: What Is the Maximum Temperature that the Epoxy Can Take?

Although epoxies are generally able to withstand high temperatures for short periods, we do not recommend them using above 200ºF.

Q: How Should I Prepare the Area?

To achieve maximum adhesion, remove oil, dirt, rust, paint and water. Use a degreasing solvent (alcohol or acetone) to remove oil and grease. Sand or wipe away paint, dirt or rust. Roughing up the surface increases surface area for a better bond.

Q: Is There an Easier Way to Mix and Apply?

The best method for mixing paste epoxies is to use a stiff knife and a flat piece of wood. The putties are mixed between the fingers. It is helpful to store the epoxy in a warm area prior to use. Art supply stores offer a variety of palette knives for applying paste.

Q: Does Epoxy Stick to Plastic?

Epoxy bonds to many surfaces including hard plastics. Plastic is a broad term and includes many types of polymers. It is always best to spot test if in doubt.

Q: How Fast Does Epoxy Really Cure?

Epoxy cures fast enough that there is significant strength after 3 hours. At 70º F the working time is 15 minutes. It is still possible to reposition work for up to 45 minutes.

Q: How Do I Clean Up Epoxy?

Uncured epoxy will clean up with soap and water, or denatured alcohol. Wash contaminated clothing. Cured epoxy can be removed by scraping, cutting or removing in layers with a good paint remover.
