How Do You Clean A Slate Patio?
Slate has been used for a long time, primarily outside, because of its sleek appearance that goes well with outdoor settings, especially when damp.
Even though it may seem slippery when wet, slate has impermeable properties, making it non-slippery.
Slate comes in different colors and designs. Its durability makes it great as flooring. However, they tend to accumulate grime over time and begin looking dull.
Sometimes when exposed to moisture so often, algae start to form, making it slippery.
Cleaning a slate patio is easy and simple. Several methods are available to tend a dull slate patio that will be convenient for you. The two main ways are cleaning it using a mild detergent soap mix, water, and a pressure washer.
Mild Detergent Soap And Water Method
This method is easy; most materials are found in your household. You can use mild soap and water when your patio needs occasional and light cleaning.
Here is a guide on how to clean a slate patio using mild soap and water:
What you'll need
- Soft bristle broom
- Mild soap
- Baking soda
- Bucket of water
- Garden hose
- Soft-bristled brush
Step 1: Sweep using a soft bristle broom
Clean the slate patio using a soft-bristled broom to sweep away dust and debris. It will make cleaning so much easier when it is time for mopping.
Step 2: Mix mild detergent with water
Use mild soap mixed with a bucket of water. Too much soap can be difficult to remove, and exposing the slate stone to harsh chemicals can deteriorate it.
Step 3: Brush the slate with a soft-bristled brush
Mop the slate with a soft-bristled brush to remove stubborn grime and bring out the stone's unique look. For stains, you can apply baking soda and scrub the area.
Step 4: Rinse with water
Get your garden hose and thoroughly rinse the patio with water after getting rid of the accumulated dirt and soapy water.
Step 5: Let it dry
Let your patio dry under the sun. It is best when it is scorching hot to speed up the drying time.
Step 6: Apply sealer
Applying a sealer is optional. However, use a sealer to add that glossy, wet look to the slate stone. A sealer will help maintain the natural look of the stone.
It's also effortless to apply with the use of a roller brush. Apply when the slate patio has dried.
Pressure Washer Method
This method is probably the easiest because it does not require a lot of materials and is quicker. When using a pressure washer, it is essential to know which type of nozzle is best when cleaning a slate patio.
This method is best if grime is stubborn to remove using the mild soap and water method.
If you're unsure what nozzle to use, start with a Green 25° nozzle. This nozzle is almost an all-around nozzle because it gives the right amount of pressure to eliminate grime and won't damage your slate patio.
The ideal nozzle, especially for a wider spread, is a White 40° pressure washer nozzle. This nozzle is perfect for wide settings and is suitable for delicate surfaces because it applies low pressure to prevent damage.
Here is a detailed, step-by-step guide on how to clean a slate patio using a pressure washer.
What you'll need
- Floor scrub brush/Soft bristle broom
- Pressure washer
Step 1: Clear the area
Sweep the area using a soft bristle broom or a handle floor brush to remove debris from the surface.
Step 2: Connect to a water supply.
Prepare your pressure washer and connect it to a water supply through a tap or a bucket, whatever is convenient.
Step 3: Pressure wash the patio
Once the pressure washer is ready with the proper type of nozzle, wash the slate patio to eliminate algae and molds. Adjust pressure depending on your liking.
Step 4: Let it dry
Let the area dry for 24 to 48 hours. Drying time may vary depending on the weather.
Step 5: Apply Sealer
Lastly, apply a sealer. This will help maintain the slate and prevents it from deteriorating over time.
Can You Clean A Slate Patio With Vinegar?
You can't clean a slate material with vinegar.
Although vinegar is considered a natural cleaner, the acidic property of vinegar can cause a chemical reaction that will damage the stone, which is why it is not advisable to use it.
If the stain is tough to remove and you want something natural, opt for baking soda. Baking soda and water will aid in getting rid of light stains and grime on the slate patio.
Do You Need To Seal Your Slate Patio?
A slate patio needs cleaning once in a while to maintain its fresh look. Slate may deteriorate over time due to weather and excessive exposure to moisture.
Applying sealer to your slate tiles may reduce tending time and effort.
Sealer can also protect the stone's natural finish while enhancing the anti-slip property of the slate. It will also prevent it from getting dull quickly over time.
How Much Does It Cost To Install A Slate Patio?
Slate installation on a wide area costs around $10,400 on average. The low average cost is around $7,200 and can go as high as $32,000.
When it comes to slate installation on a patio, it will cost you around $9 to $40 per square foot. Price may vary depending on labor, landscape preparation, the quality of the material, and the brand.
