We LOVE this poured and stamped concrete patio. Made in 2021, this fantastic addition to the house serves as a fun get together space. How to Seal Coat Concrete is a new process for us, but an important one for anyone with concrete.

Designing a concrete patio took a lot of effort, time and work. However, if we would have hired this job out it would have cost upwards of $20K. All-in-all, this job cost us only around $2,200.

How we added over $12K to our house value!

Cost to Seal Coat Concrete

Having a concrete patio is great, and keeping it safe and protected is important by doing a Seal Coat.

Depending on the product you pick for seal a seal coat, you can spend anywhere between $100-$300 for 5-gallons. Then you also need a foam roller, roller handle and paint trays.

• Concrete Seal $150
• Foam Roller and Handle $18
• Paint Tray $20

The total cost to this project, how to Seal Coat Concrete, cost $188.

Materials Needed

To seal coat a concrete patio or driveway, the BEST product around is Butterfield Color Clear Guard Cure and Seal. It comes in a 5-gallon pail. You also need a foam roller, roller handle and tray.

Materials

• Concrete Seal
• Foam Roller
• Roller Handle
• Paint Tray
• Pressure Washer

Once you have all your materials, the seal coat and roller brush with tray, you then need to clean the concrete. Using a pressure washer, clean the concrete completely. Clean off any stains, bird droppings, leaves and debris.

Which Pressure Washer to Use?

Not all pressure washers are made the same. There are some that are SUPER cheap, not greatly build and then do not do a great job. You don’t have to spend a fortune on a pressure washer but do research and find the BEST one for your price range.

There are two types of pressure washers. There is gas powered and electric pressure washers. Gas powered pressure washers can provide a stronger and longer source of power, while electric pressure washers can give plenty of reliability and power while you get your job done.

Pressure Washer Differences

For light duty jobs, like cleaning patio furniture, vehicles and walkways, a pressure washer with a PSI of 1700-2200 is good.

For medium duty jobs, like cleaning docks, fences and garage floors, a pressure washer with a PSI of 2300-3000 is great.

For heavy duty jobs, like cleaning decks, siding, driveways, second floors of buildings, oil stains, a pressure washer with a PSI of 3100-4000 is great.

Clean the Concrete Patio

So, doing a concrete patio, needing a pressure washer with a PSI of 2300-4000 is where you need to be. Our pressure washer is a 2700 PSI electric machine that worked amazingly well at this concrete cleaning job.

Using the nozzle, move the pressure washer wand in lateral direction over the concrete, cleaning off any debris, dirt and stains.

Steps to Seal Coat Concrete

Once you have the concrete cleaned with a pressure washer, make sure it dries completely before starting to seal the concrete.

Additionally, to the concrete being dry, you need to do the sealing when the temperature is above 70 degrees Fahrenheit. Having the temperature right helps curing, providing a successful seal.

A good painter’s foam roller with an extendable handle helps to save your back while rolling on the concrete sealer.

Open the concrete sealer, then carefully pour the sealer into a paint tray. Using the painters foam roller, inserted into the roller handle, dip the roller into the sealer and then run it through tray.

Roll the sealer covered roller onto the concrete and paint it on in an even and thin layer. Make sure to not leave streaks or giant globs of sealer in pools over the surface.

Keep dipping the roller into the sealer and painting it onto the concrete in thin and even layers. Work your way from the farthest part of the concrete and go in one way, not random.

Keep painting on the Concrete Seal Coating so you cover all areas and edges of the concrete patio. We have a walkway from the lower patio to the upper patio that is attached to the house.

When the entire concrete patio is sealed, let it cure and then dry for up to 24 hours. After 8 hours, it is then safe to walk on, but do not do so until it is fully dried.

After 24 hours of the concrete drying, give it a second coat so you have a full years’ worth of protection on your concrete.
