How to paint garage floor

Learn how to paint your garage floor to preserve it from stains and damage while also creating a durable surface that gives it a showroom appearance.

5 Steps To Paint Your Garage Floor

Step 1: Using a concrete grinder, diamond grind your garage floor.
Step 2: Clean the cracks and gaps in the concrete floor of your garage.
Step 3: Epoxy paste can be used to fill gaps and cracks.
Step 4: Paint epoxy primer onto your garage floor.
Step 5: Paint epoxy top coat to your garage floor.

Step 1: Using a concrete grinder, diamond grind your garage floor.

You must clean the concrete and remove any coatings or dirt before applying epoxy to your garage floor. To accomplish this, use a vacuum-assisted concrete grinder to diamond grind the whole garage floor back to bare concrete.

Step 2: Clean the cracks and gaps in the concrete floor of your garage.

Once you have a clean and bare concrete floor in your garage, you will be able to see every crack and hole in the floor. To clean the cracks, softly chase out all of the gaps using a hand-held concrete cutter. This removes any loose particles from the cracks in the concrete. You may now vacuum the garage floor; alternatively, a leaf blower can be used to blast out the gaps and holes that the vacuum can't reach. The cleaner the concrete is, the better for epoxy flooring.

Step 3: Epoxy paste can be used to fill gaps and cracks.

You're ready to fill the gaps and holes with epoxy paste now that you've cleaned the entire garage floor as well as the concrete cracks and holes. To do so, mix epoxy resin and filler powder together to create an epoxy paste that is ready to patch holes and cracks. Paste the cracks and holes with a broad knife or a concrete trowel until the epoxy paste reaches the bottom of the crack and is flush with the top of the concrete floor.

Step 4: Paint epoxy primer onto your garage floor.

To apply epoxy primer to your garage floor, start by prepping enough concrete around the edges to paint, a procedure called cutting in. You're ready to roll on the epoxy primer the rest of the way once you've coated it around the perimeter of the garage floor. Make enough epoxy to cover the garage floor; the application rate for the epoxy you're using can be found on the epoxy data sheets. Rolling epoxy from left to right and then back rolling, front to back, once enough epoxy has been poured to the garage floor is a good method.

Step 5: Paint epoxy top coat to your garage floor.

Before applying the final top layer of epoxy to your garage floor, scrape the floor, vacuum it, and epoxy paste any gaps and cracks. Roll on the epoxy top coat the same way you rolled on the epoxy primer, side to side and back to back. Back rolling your epoxy ensures an equal application of the garage floor finish.

Conclusion On How To Paint Your Garage Floor

Preparation is crucial; diamond grinding the garage concrete floor ensures that the epoxy will adhere properly. You're repairing the floor by using epoxy paste to fill in the concrete fractures and gaps. By cross rolling the epoxy on your garage floor, you can ensure a uniform application of the resin and a beautiful, well-coated surface that will last for years.
