Whether you are working with fiberglass, carpentry, cements, metals or plastics, epoxies are the perfect choice when you need an extra strong bond. After you learn how to choose the right epoxy resin for the material you’re working with, you can confidently move forward with your project. This guide will help you understand how to use epoxy correctly, so you can achieve the best results for your project.
An epoxy is a two-part adhesive that forms when you mix epoxy resin and hardener. The two substances are stored in different containers and are only mixed together when you’re ready for gluing – which you can do either automatically with an instant mix syringe or manually by mixing it on a separate tray. You should keep the mixing ratio 1:1, otherwise the resin will not crosslink to form the strongest possible bond.
After you mix both components, the working time begins. That is the period during which the parts to be bonded can still be moved and changed. The working time can range from a few minutes to a couple of hours depending on the glue you use. After the working time, the glue needs several hours to reach maximum strength.
Epoxy is highly versatile and extremely strong, making it great for DIY projects. It is also a gap-filler, which makes it perfect for repair works and restorations. On top of that, epoxy can be sanded, drilled and painted. This gives it a much wider range of uses than standard glue.

If you have cracks in your garden step stones, you can easily fix them with the right epoxy. When choosing your epoxy, keep the intricacy and special requirements of your project in mind. For example, if you need a considerable amount of time to position the pieces of your project after applying your epoxy, you will want to choose an epoxy with a longer drying time.
