How To Pressure Wash Your Garage Floor Properly

If you have a garage, you know there are times when the garage floor can become quite messy. Maybe it is just sandy and dirty, or maybe there is oil and sludge mixed in from working on cars. Either way, you may want to pressure wash your garage floor. It is important that you do it properly. 

How to pressure wash your garage floor properly? To properly pressure wash your garage floor, you need to first soak your floor with a degreasing solution. Let the stains soak with some of the solution, add a degreaser to the pressure washer, and choose a low-pressure tip for your cleaning wand. 

If you want to keep your garage floor clean, pressure washing the floor is one of the best ways you can do that. It is easier than scrubbing it with a mop, vacuuming it, or sweeping up the dirt. 

There are a variety of ways you can pressure wash your garage floors. The two main ways are to do it yourself, after buying or renting a pressure washer, or to hire someone to do it for you.

Steps to Take When Pressure Washing Garage Floor

If you are going to pressure wash your garage floors on your own, you should: 

  • Soak your floor with a degreasing solution
  • Let the stains soak with some of that solution
  • Put some of the degreaser in your pressure washer
  • Choose a low-pressure tip for your cleaning wand
  • Pressure wash your garage floors

You can also hire someone to pressure wash your garage floors for you. In this case, you just call up someone to do this for you, sit back and let them do the work. 

Pretreat Your Garage Floor Before Power Washing It 

Before you start pressure washing your garage floor, you should empty out the garage as much as you can. This way nothing gets damaged by the water. Once you have it emptied, you can sweep it out to get rid of loose debris and dirt. 

If there are walls that can’t be wet, tape up plastic drop cloths to the lower part of each wall. Start by wetting the floor down with a garden hose. Put a degreaser on any spots where there are grease or oil stains. You can scrub these stains with a brush to make sure the degreaser really penetrates each stain. 

Let your stains soak for around 20 minutes, but don’t let them dry. 

Should You Pressure Wash Concrete Garage Floors? 

Yes, you can and should pressure wash your concrete garage floors. However, you need to make sure you are cautious about the tip you use for pressure washing. It should be a low-pressure tip. 

The finer nozzles can do a great job, especially when spot-cleaning any grease stains you might have.  

If you have mildew or moldy-covered concrete, you should use a low-pressure tip and coat the top of these spots with soap suds first, before pressure washing the floor. 

People often don’t know that they can damage their concrete garage floors by pressure washing it. If you use the right tip, you can prevent damage to your garage floor.

What PSI Should be Used to Properly Pressure Wash Garage Floors? 

If you are going to be pressure washing your garage floor, you will probably want an adjustable PSI pressure washer. However, in general, for concrete floors, you will want to use 3000 PSI

There are many different pressure washers you can get. Check on the PSI level and whether it is adjustable before you buy a pressure washer. If you are paying someone to come pressure wash your garage floor, ask them what PSI they will be using. 

Should Concrete Garage Floors Be Sealed After Pressure Washing Them? 

Many people don’t consider sealing their concrete garage floors. However, when you are pressure washing your concrete garage floors, which should be done once each year, they should be sealed to prevent further weather and wear damage. If you want to save yourself money in the long run, sealing concrete garage floors is a great idea.

Choosing the Right Pressure Washer for Your Garage Floor

You can get either electric or gas-powered pressure washers. The water pressure is always in PSI or pounds per square inch. You will want to pay close attention to the PSI and water flow rate, which is the GPM or gallons per minute. 

To clean garage floors that are concrete and unpainted, you will want to use a gas-powered pressure washer at a 3000 PSI and 3 GPM. Going lower than this won’t remove oil or dirt stains. If you don’t have a pressure washer with these rates, you can always rent one or buy one. 

Tips on Pressure Spraying Your Garage Floor 

Some of the tips you will want for pressure spraying your garage floor include the following: 

  • Always let the degreaser soak for a bit before pressure washing the garage floor
  • Hook up your garden hose to your pressure washer per the instructions
  • Choose a spray nozzle that is 15 degrees (25 degrees if your floor isn’t that dirty)
  • Try different nozzles if your floor isn’t getting clean enough
  • Have the tip around 1 foot from your floor when spraying
  • Don’t spray on 1 spot for too long 
  • Make multiple passes over dirtier areas
  • Work your way toward the door

Pressure washing does take some time. However, it isn’t too tough of a job. Depending on the size of your job, it will probably take between 1 to 3 hours to fully pressure wash your garage floor. This is based on the size of your garage, the pressure you are using, and how dirty your garage floor is at the time.
