How to Apply Epoxy Paint to Painted Cement Floor

Epoxy paints are more durable than concrete paints and offers a level of sheen that paints can’t. Here is a guide on how to apply epoxy paint to painted cement floor.

Preparation

Preparation is key when applying floor coatings especially when you are working on surfaces that are high-traffic areas. Before you begin your project, make sure to clean the area free of any loose debris and dirt. This includes wax, grease, and mildew. Give it a clean off first with a broom or vacuum cleaner just to get rid of the bulk of the dirt and dust. Improperly cleaned surfaces will interfere with the primers adhesion. Proper preparation will ensure maximum adhesion, durability, and uniform coloration. If you are working with bare cement, you can use a cement masonry cleaner and etcher to degrease and clean the area. This will remove grease, oil, auto fluids, rust, and dirt. Generally, when dealing with concrete it pays to acid wash it first. Acid washing is generally a four parts water to one part acid. The idea of this is obviously it will clean the concrete and slightly etch into it to give you a nice surface with the paint to bond onto. Check here!

Method

Now we are ready to apply the primer. If the cement floor is already painted, you can apply a fresh coat of the aqua seal waterproof or sealer and primer to the cleaned cement floor so the epoxy floor coating will adhere with the new primer. You will want to apply with thin coats by brush roller or spray. Don’t overcoat as it may cause running or puddling. Wait for 2 hours before applying a top coat. If the humidity is high, you may need extra drying time.

The next step to finishing the cement floor with the epoxy show coat. You don’t want to apply this product in extreme heat or in direct hot sunlight. Keep in mind that the area should be unused for three days after the application to cure. Again, ensure the surface area is clean and free of loose debris. Hand steer your epoxy show coat, apply and thin multiple coats by brush roller or spray. Never over apply and allow four hours of dry time. It should stay longer for extreme humidity. Two to three coats are recommended depending on the color.

Depending on how big the area you are painting, it sometimes pays to have one person cutting in and another person rolling behind you. That way you’ll keep a wet edge and you’ll avoid getting any marks between what you have rolled and cut in. now the main difference between the first and second coat is with a second coat you’ll want to try to fill all the pinholes and you can either use your brush or even the roller on its side and just force the paint in to all those little holes in the concrete. Now the other thing about the second coat is you’ll find it’ll be a lot easier to apply. Learn more details at: https://www.wikihow.com/Do-Epoxy-Flooring
