Power washing concrete is among the easiest surfaces to power

wash. However, if there is a coating to the concrete, we may need

to make sure that it is not peeling or flaking, as the power washer

could damage it if this is the case.

     Materials:

• A gas power washer (at least 2500 psi for a wood-sided or

       vinyl-sided house)

• A garden hose

• Gasoline

• Ear protection

• Surface cleaner

• Soap for concrete (recommended: Zep Driveway & Concrete Cleaner) and pump sprayer

• Anti-vibration gloves

1. Setting up the Power Washer

We will start by connecting the power washer to the hose, power hose, and power washing wand and turning the water on.

 

   2. Testing the Power Washer

Once the power washer is set up,we then squeeze the trigger to  

check to make sure the water is in an evenly dispersed “V”. If it is

not, the nozzle is most likely clogged and we clear it out with a pin.

 

   3. Turning the Power Washer On

Once we’ve checked that the power washer is functioning properly, it is time to turn it on. This will involve pulling on the cord and may involve experimenting with different positions for the "choke/run"lever to see which works best (it varies by day).

​

   4. Making Sure the Power Washer is Up and Running

Once the power washer is turned on, we will then squeeze the trigger to make sure that it is up and running properly. This sometimes takes a couple minutes for the power washer to warm up.

​

   5. Putting the Soap On (Sometimes)

The soap isn't always necessary, but when we use it, it would be applied now with a pump sprayer.

​

   6. Washing the Concrete

Next we attach the surface cleaner to the power washer. Then we use the surface cleaner to go up and down the concrete until a whole section is completed. Then, we put on the nozzle and use it to blow the extra water out of the way. The nozzle is often used to touch up certain areas and to clean the edges that the surface cleaner can’t reach. The power washer frequently leaves lines in the concrete after it has been washed, so if there are, we’ll need to go over it again in a different direction.

​

     7. Repeat Until Finished

Then we'll repeat steps 5 & 6 until the job is complete. We make sure to find a good spot to drain the excess water so that it doesn't get any of the customer's property dirty.
