However, over time, patio slabs can become plagued with unsightly mildew and algae growth, particularly in shaded or damp areas.
Algae on patio surfaces not only look unpleasant but can also create a slip hazard.
In this blog post, we’ll explore effective methods for removing mildew and algae from your patio, ensuring it remains a safe and inviting space.
Gathering Necessary Supplies
Before starting the cleaning process, it’s important to have all the necessary supplies on hand. Here’s a handy list to get you prepared:
Stiff-bristle brush or scrubbing brush
Garden hose with a spray nozzle or a pressure washer
Protective gloves and eyewear
Broom or leaf blower
Tarp or drop cloths to shield nearby areas
Cleaning agents
Oxygen bleach, which is great for tackling mildew
Algae remover specifically designed for patio surfaces
White vinegar, a natural cleaning alternative
Baking soda for those tough stains
Chlorine bleach for the most stubborn mildew (just be careful with certain materials)
With these supplies, you’ll be ready to tackle any mildew or algae that has taken over your patio.
Preparing the Patio Area
Preparing your patio for cleaning is a straightforward but essential step.
Start by moving all your furniture, potted plants, and decorative items to another spot. This will give you clear access to every inch of your patio and protect your belongings from any potential damage.
Next, grab a broom or a leaf blower to sweep away loose debris, leaves, and dirt.
To protect plants and nearby surfaces from cleaning agents, cover them with a tarp or drop cloth. This is particularly important if your patio is next to wooden decking or porous materials.
Taking these preparatory steps will ensure that your cleaning process goes smoothly and that everything stays in great shape.
Cleaning Methods for Mildew
To get rid of mildew on your patio, start by mixing oxygen bleach with warm water according to the instructions on the package.
Wearing gloves and protective eyewear, apply the solution to the mildew-infested areas using a stiff-bristle brush. Focus on small sections at a time to ensure thorough coverage.
Let the solution sit for about 10-15 minutes so it can break down the mildew effectively. After that, rinse the patio well with a garden hose or pressure washer to remove any residue.
If you prefer a natural approach, a mixture of white vinegar and water works wonders for less severe mildew. Just apply it in the same manner and scrub away.
Dealing with Algae on Your Patio
Algae can make your patio look grimy and can even be slippery.
If you’re dealing with light algae growth, start with a simple solution of water and baking soda.
Sprinkle the baking soda over the algae, then scrub it with a stiff-bristle brush. This should break up the algae and make it easier to wash away.
For more stubborn patches, you’ll want to use an algae remover that’s specifically designed for patio surfaces.
Follow the manufacturer’s instructions for application and let the product sit for the recommended time. Afterward, scrub the area thoroughly with your brush to ensure all the algae is lifted.
Once you’ve scrubbed away the algae, rinse the area well with a garden hose or pressure washer. Make sure to get rid of all the cleaning solution to prevent any residue from affecting the patio’s appearance or feel.
Remember, consistent cleaning can prevent algae from taking over, so make this a regular part of your patio maintenance routine.
Preventive Measures
To keep your patio looking its best and free of mildew and algae, regular upkeep is essential.
Start by sweeping your patio frequently to remove leaves, dirt, and other debris that can hold moisture and encourage growth.
Address any drainage issues promptly—standing water is a major contributor to mildew and algae.
Think about how much shade your patio gets. If it’s heavily shaded by trees or bushes, consider trimming them back to allow more sunlight to reach the area. Sunlight helps to dry out moisture and discourages growth.
If your patio is made from a porous material like concrete or sandstone, applying a sealant can provide an extra layer of protection.
Another tip is to move outdoor furniture and potted plants around occasionally. These items can trap moisture beneath them, creating ideal conditions for mildew and algae. By moving them, particularly out of shady areas, you allow those areas to dry out properly.
Consider setting a schedule for light cleanings using your preferred method. Whether it’s a quick scrub with a vinegar solution or a spray down with a hose, frequent maintenance can stop problems before they start.
If you live in a particularly wet or humid climate, you might need to increase the frequency of these cleanings.
By staying proactive, you can enjoy a beautiful and safe patio year-round.
Removing Mildew and Algae from Your Patio
Cleaning your patio can seem like a big job, but it doesn’t have to be overwhelming.
By gathering the right supplies and taking the time to prepare properly, you’ll be well on your way to a sparkling clean outdoor space.
Regular upkeep will not only keep your patio looking great but also prevent mildew and algae from taking hold in the first place.
Simple steps like sweeping often, addressing drainage issues, and allowing more sunlight to reach your patio can make a huge difference. Moving furniture and potted plants around occasionally will also help keep moisture from building up.
By making these tasks part of your regular routine, you’ll maintain a beautiful, safe patio that enhances your outdoor living experience.
So roll up your sleeves, get scrubbing, and enjoy your refreshed patio!
When you’re planning a concrete slab, it’s important to consider drainage. If it’s exposed to the elements, the slab should have enough slope so water can drain off of it.
For example, in the video above, we want the new concrete patio to be flush with an existing slab, so we slope the forms in the opposite direction by about one or two percent.
It’s also important that a slab be thick enough to be durable.
The thickness depends on what you’ll be using the slab for. Concrete driveways and patios need to be at least 4 inches thick, whereas concrete countertops only need to be one and a half inches thick.
In the video above, we want this patio to be at least 3-1/2 inches thick because we’re pouring the concrete over old pavers. So, we use a 2-by-4 gauge block to ensure we have that clearance.

3. Forgetting Reinforcement
Concrete slabs are high in compressive strength, which makes them great at resisting compression forces and impact. But when it comes to tensile strength, or the capacity to resist pulling-apart forces, concrete doesn’t fare as well, according to ConcreteNetwork.com.
This is where steel reinforcement wire can help. Steel reinforcement provides additional structural support for concrete slabs. This is especially important if it will be exposed to heavy traffic.
It’s not uncommon for air bubbles to develop inside the slab as the concrete is poured. So, it’s a good idea to tap the exterior of the forms to help release them and improve the slab’s strength.
As the concrete cures, it will shrink some and may crack. To accommodate for this shrinkage, use a concrete groover to add some expansion joints as the slab cures. This way, if the slab expands, it’s more likely to do it inside these shallow grooves, where it mars the finished surface of the slab.
This week, we’re transforming a breezeway that looks almost accidental into a more inviting entrance.
Delane Caldwell’s breezeway to her front door is just a narrow hallway to the backyard, but we’re going to find a way to incorporate it more as a living space.
The Projects
Grinding the concrete smooths out the uneven surfaces of the patchwork slabs. (3 Echoes Content Studio)
Refinish the Concrete Slab
The concrete in the breezeway looked like a patchwork of slabs. So, to create a uniform-looking slab, we smooth the concrete surface with a grinder.
Coating the breezeway with concrete epoxy paint creates a uniform color throughout the breezeway. (3 Echoes Content Studio)
After we sweep the dust away and rinse the slab off with a water hose, we paint the new smooth slab with a base coat of white epoxy paint.
After the base coat dries, we pop a chalk layout line on the slab to start our stenciling.
This stencil pattern is based on traditional Portuguese Azulejos tile designs. We used black epoxy paint to fill in the tile pattern on the concrete.
Curtains make this space feel more like an outdoor living room than a breezeway. (3 Echoes Content Studio)
Hang Curtains
To make the breezeway feel more like a living space, we remove the chain link fence at the end and add curtains.
The fence posts are set in concrete, so to remove them, we’ll need some leverage. After digging up the dirt around the base, we place a concrete block next to the post to act as a fulcrum for our shovel.
To make the curtain rod wide enough to fill the breezeway, we connected two galvanized pipes together with a tee fitting. (3 Echoes Content Studio)
Our curtains are going to hang the curtains from a galvanized threaded rod. We first measure the breezeway to ensure our rod is long enough to span the entire opening.
Etching the galvanzied pipe with vinegar ensures the spray paint will stick. (3 Echoes Content Studio)
Before we install the rod, we paint it black to match the wrought iron. But, before we can paint, we have to etch the rod with vinegar to ensure the spray paint adheres to it.
Green leafy plants with varying heighth add depth and breadth to the garden space. (3 Echoes Content Studio)
Fill Garden Bed
Our next project is to transform the garden bed inside the breezeway from a dirt pit to a green oasis.
We add a mix of green, leafy plants to fill the once-defunct garden space.
We surprised Delane with a smart lock deadbolt to not only dress up her front door but also make her home a little more secure.
The Kwikset Halo Touch Wi-Fi Fingerprint Smart Lock uses Delane’s unique fingerprint to open and lock her front door. This single-cylinder deadbolt also can be locked or unlocked by using the keypad or key from the outside as well as the turn button from the inside.
The smart lock has built-in Wi-Fi that connects directly to the home Wi-Fi network and smartphone for a secure smart home that does not require a third-party smart home hub, panel or subscription.

Post-Production Thoughts
Delane’s breezeway is the main entrance to her home, but before it had a very tired and haphazard feel to it the random collection of different slabs on the floor only left visitors with questions about what the space was supposed to be.
The sad empty planting bed made the house feel a lot older than it actually was, and the chain link fence made it feel more like a cage than a relaxing space.
But now, the whole Space is taken on the field of a courtyard in a fancy hotel the consistency of the stencil floor ties everything together from the wrought iron gates to the lush green planting beds.
The door adds a pop of color while the fountain adds a cool visual element and a peaceful soundtrack for the space.
The simple curtain rod and the curtains frame the backyard and somehow make it all feel like a resort and we did it all for less than $1,200.
Oversized Tic-tac-toe is a great way for the family to play games together and enjoy the outdoors.
Tic-tac-toe, also known as Naughts and Crosses, has entertained people for centuries. It’s been found everywhere from the temples of ancient Egypt to the medieval cathedrals of England, according to UC Berkeley GamesCrafters.
Read on to learn how to make concrete Tic-tac-toe pieces.
5 spray-paint can lids or another cylindrical object
Fast-drying caulk
Melamine shelf boards
Miter saw
Wood screws
Drill & Drill bits
Tape measure
Wood pencil
Trowel
Silicone cake pans allow for easy removal once the concrete pieces are cured. (3 Echoes Content Studio)
Create Forms
To create forms for o’s, use 6-inch silicone cake pans and lids from spray-paint cans. Glue the lids to the centers of the cake pans with fast-drying caulk. Wipe off the excess caulk.
Melamine has a hydrophobic (water-resistant) coating that allows concrete to cure at the surface. This makes it easier to remove when the concrete is cured. (3 Echoes Content Studio)
To make the x’s, cut a melamine shelf board to build a 30-inch by 6-inch open tray.
A miter saw makes it easy to cut the triangles at a perfect angle. (3 Echoes Content Studio)
You need two triangle sizes to create the x’s:
Cut 10 triangles at a 38-degree angle from a 2-inch piece of melamine board.
Cut 10 triangles at a 59-degree angle from a 1-⅞-inch piece of melamine board.
Once the concrete is thoroughly mixed, scoop it into the forms and use the trowel to level the mix with the top of each form. Cover the molds with plastic to help curing.
Let the tic-tac-toe pieces cure for five days in warm weather (at 70 degrees Fahrenheit or higher) or for seven days in colder weather (50-70 degrees Fahrenheit).
Once the pieces have cured, remove them from the forms. Rough edges can be easily removed by sanding.
Now, all you need is a little sidewalk chalk to draw your game grid — then the fun can begin!
When the house at the end of the cul-de-sac hasn’t changed in 28 years, it’s time for some front porch rehab.
This house belongs to Jeff and Eliese McAllister. The couple, known as Lolli and Pop to their grandchildren, want to update the front porch on “Camp Lollipop” so their grandchildren can enjoy their front yard as much as their children did while growing up.
The porch is blocked off by tall shrubs and is too narrow for the couple to comfortably sit and watch their grandchildren play.
And that’s where we can help!
The Projects
“Open concept” isn’t just for interiors! We’re opening up this front porch.
Opening Up the Front Porch
Removing the shrubs and handrails blocking Jeff and Eliese’s front-yard view is our first big job.
We have to pressure-wash the house to create a clean slate to start our work. Jeff and I remove shrubs, with the help of the couple’s grandsons, while Chelsea and Eliese tackle the handrails.
This is what happens when your wood isn’t treated before painting or staining it.
Because the wood handrails aren’t treated, they are rotting away. So, knocking them out with a sledgehammer is the best way to open up the porch — and, maybe, release some tension along the way.
After removing the handrails, we apply putty and sand the columns so it’s like they were never there, to begin with.
Repairing siding isn’t just a cosmetic fix; it can prevent bigger problems later on if the elements enter your home.
Repairing the Shutters and Dormers
This curb appeal makeover requires more than opening up the front porch. We’ve noticed some problems that needed immediate fixes!
First, we repair the ground floor’s damaged shutters. Then, we get up on the roof to repair siding on the dormers. Of the 12 shutters on the front of this house, just one set has a little wood rot. So, Jeff doesn’t want to replace them all.
Since none of these pieces were standard lumber sizes, we had to cut them down on the table saw. Chelsea used the old pieces as a pattern to cut new pieces from the fiber cement material.
A Woodcraft WoodRiver General Purpose Carbide Tipped Saw Blade comes in handy when you need to make custom cuts.
This front porch is coming along, but it could use more character. We will paint the porch to add some.
Painting the Front Porch
After all the repairs were done, we put a fresh coat of paint on the siding, trim and front porch ceiling. The green shutters clashed with the red-tinted wood door, so we painted them gray to tone it down.
The painted pattern adds a pop of color to this front porch.
The concrete on the front porch has seen better days. Instead of gutting the concrete, we painted a pattern on it using a stencil! It’s a great way to give your concrete a fresh look without breaking the bank.
Spreading out the new flowerbeds adds to the open feeling.
Planting New Flowerbeds
Next, we added some fresh landscaping. Before, the plants were too concentrated at the front of the porch, so we spread them out to maintain the open space feel.
Finally, we put down a fresh layer of pine straw to finish off the flowerbed.
We also:
Added address numbers to the porch column
Removed the intercom/doorbell
Installed a new porch light
Installed soffit vents
Replaced the rocking chairs

Post-Production Thoughts
This front porch rehab really brings things full circle: Jeff and Eliese’s kids grew up here, and now they’re seeing their grandkids grow here.
At one point, the couple thought about selling the house. But with this new front yard, they’re happy to be able to stay in the home they raised their kids, and now, their grandkids as well.
