Curing of epoxy resin - so much time is needed!

In order to avoid misunderstandings here, the curing of epoxy is not the same as the time it takes to dry. The curing can be additionally supported by various methods. However, it can take several days for the epoxy resin to dry completely and be impact-resistant.

Dry epoxy

During the dry season a lot can happen to the epoxy resin. It can become dull or rough and brittle due to the wrong environment. The first way to avoid this is to have a room with a high temperature that nobody enters for about 24 hours.

Each speck of dust will try to settle on the epoxy in the first few hours. Some things you can remove if you blow the epoxy with a hot air blower and at the same time fish out the foreign body with tweezers. But this is only very shortly after the application.

Hardening and strength

It can take up to seven days for Epoxy to be truly impact-resistant and solid. Although the epoxy has dried well after about a day, it has not yet reached its full stability.
