Epoxy Basement Floor Paint Project

When it comes to a basement floor paint project there are a lot of different things to think about before you get started and then while you are actually in the process of doing the project. As with most other things, the amount of planning you do will be directly related to the success you have. Using a floor paint is not just opening the can and rolling it out as there are other factors involved.

As long as your basement will not get a lot of direct sun, an epoxy will work very well for you. You have two choices when using epoxy floor paint, it can either be water based or solvent based. Both of these have pluses and minuses and they both are two part products which means the resin and the hardener will need to be mixed together before the solution is painted on the concrete floor.
Solvent based two part epoxies will end up with a coating that is thicker than the water based variety generally. It can often times be two or three times thicker. This is because of the amount of water that needs to be evaporated after the product is rolled out. The down side to the solvent based epoxy is the odor and vapors. This is not recommended in a basement because of the VOC’s that will be gassed off during the curing process. It also is very difficult to clean up you will need some sort of solvent to take care of the tools and any type of over splash.

Very Good Basement Epoxy Paint

The water based epoxy product is much easier to clean up, only soap and water are necessary, and it does not have the same problems with smell. This is a very good product for home basement use because the foot traffic does not make a really thick coating necessary. You can expect a 3-4 mil covering with water based epoxies which will be good for your floor.
The preparation for an epoxy basement floor paint is really the most important part. First you need to be sure there are no moisture problems in the floor slab. The best way to do this is to tape a 3’ by 3’ plastic sheet down on the floor and leave it for a few days. If water spots appear on the underside of the sheet then you have a moisture problem and that needs to be taken care of first.
If your floor is dry then the next step is to move to cleaning. Wash the floor with soap and water and then rinse it thoroughly. If you have any grease spots then this will need to be removed with a degreaser as any grease or oil residue will not allow the epoxy paint to adhere to the floor. Also, check for mold and mildew. If they are present then use a bleach mixture to remove them.
Allow the floor to dry and then you can start the actually painting. Pour the hardener into the resin mixture, not the other way around. Follow the directions for set time before applying the paint. This is very temperature dependant so be sure you use the correct times. If you plan to use a non slip grit additive then it should be mixed in now.
Start by cutting in all the edges with a brush and then roll the paint out in about a 4’ square before spreading the colored paint chips in that section. Then move onto the next section. Literally, do not paint yourself into a corner. Be sure to work towards the exit.
You should be able to walk on your floor within about 12 to 18 hours depending on the ambient temperature. Clean up is with soap and water.
This is a great project for a DIY person and can really improve the looks of your basement.

  1. I am wanting to paint my concrete front porch with an epoxy paint. Can I just follow directions for basement or garage floors, or is there something different I need to do before starting?

  2. Hi Margaret,
    Basically you will be going through the same steps. The only real difference may come into play if your porch is not walled in. In this case the weather will play a bigger factor in your project. Be sure the weather is going to be dry and the temperature will be in the range that is required for the product you are going to use. This information will be located on the can or box. If your porch is walled in then you can just use a heat source in order to control the temperature like you can in a garage or basement. Good luck with your project and send me a picture when you get done.
