It takes a while for this chemical reaction to be completed which is why two-part epoxy paint takes longer to dry. The hardener and resin will ignite a chemical reaction that will produce exothermic heat. Both parts come together but the user has to mix them to create the epoxy paste which will then be applied to the concrete. The main reason two-part epoxy paint takes longer to dry and cure is that the paint contains a hardener and a resin. Also, the concrete should be washed and sanded before the paint is applied. That said, two-part epoxy paint should be applied at room temperature above 60 degrees F.
Also, relative humidity, room temperature, and surface preparation depend on how quickly the two-part epoxy will dry and cure. Two-part epoxy paints should be left to cure for at least 30 days or longer before the paint is exposed to solvents and cleaning. However, the paint should be left to harden enough before automobiles including motorbikes are parked or moved on the finish. It will take at least 24 hours for two-part epoxy to be strong enough to handle weight and foot traffic. On average, two-part exposure paint will take 2 hours to dry to touch and about 8 hours to dry enough for a re-coat. Two-part epoxy takes longer to dry and cure than one-part epoxy paint. And that’s why one part epoxy dries quicker when compared to other epoxy resins like the two-part epoxy. This process is very similar to how traditional paints dry and cure. But, one part epoxy paint goes through a process called “air-drying.”Īir-drying is a process where the paint particles in the one part epoxy dry and harden based on exposure to cool air. Other epoxy paints require a chemical reaction to dry and harden. This is because one part epoxy is a latex acrylic floor paint with epoxy resins added into the paint formula. One part epoxy has a fast drying time when compared to other epoxy resins. Epoxy paint should be applied at temperatures above 60 degrees F for adequate dry and cure time.
It will take at least 30 days before you can wash and clean 1 part epoxy with a solvent. But, 1 part epoxy isn’t commonly used on garage floors and car parks. It takes at least a week (7 days) before you can park or move automobiles including motorbikes on 1 part epoxy. And, it has a 24 – 72 hours cure time before it can be subjected to foot traffic. To re-coat, 1 part epoxy needs between 4 – 6 hours. It takes less than 2 hours for 1 part epoxy to dry. The drying and curing time of the epoxy depends on the ambient temperature, humidity, and application of the epoxy paint.īut there is more to know about the drying time of epoxy. On average, 1 part epoxy will take up to 4 days to cure while 2 part epoxy will take 7 days to cure. You can walk on epoxy flooring 12 hours after application but epoxy paint curing will take several days. However, it will take at least 12 hours for the epoxy paint to handle the weight. So how long do this take?Įpoxy paint takes between 4-6 hours to become dry enough to touch. But before you can use or enjoy the hard epoxy finish, the paint has to dry and cure.
Epoxy paint produces one of the hardest finishes out there.
