Various materials

Patio slabs can be made of a wide variety of materials, all of which have different requirements:

  1. Natural stone: This includes granite, slate, sandstone, travertine and limestone.
    Natural stone slabs are durable and give the patio a natural, elegant look.

  2. Concrete: Concrete slabs are versatile, robust and available in many designs.
    They can be colored, patterned or textured to create different styles.

  3. Ceramic: Ceramic and porcelain stoneware tiles are particularly resistant to stains and scratches.
    They are available in many designs and colors and are often easier to clean than natural stone.

  4. Wood: Wooden boards made from hardwoods such as teak, oak or bangkirai offer a warm and natural aesthetic.
    They require regular maintenance to withstand the effects of weathering.

Cleaning concrete patio slabs

Concrete slabs are robust and durable options for your patio.
A pressure washer and a surface brush are often ideal for cleaning concrete slabs.
First sweep away loose dirt with a broom.
Then use the pressure washer in combination with clear water to thoroughly clean the slabs.
Cleaning agents can be used for stubborn stains.
Our Biosativa® cleaning concentrate is ideal for use on patio slabs as it is completely biodegradable without losing any of its effectiveness.

The following steps are recommended for more intensive cleaning of heavy soiling:

  1. Pre-treatment: Apply the Biosativa® Cleaner diluted as specified in the data sheet to the concrete slab and leave it to work for a few minutes.
    This helps to loosen the dirt.

  2. Scrubbing: Use a hard brush or scrubbing brush to thoroughly remove the loosened dirt and stains.
    Be careful not to be too aggressive so as not to damage the surface of the tiles.
    Find out in advance which accessories are right for your application.

  3. Rinsing: After scrubbing, rinse the tiles with clean water.
    A high-pressure cleaner can be particularly effective in removing all residues.
    But you should also proceed carefully here!

  4. Algae and moss: If there is algae or moss on the tiles, special algae and moss removers can be helpful.
    Alternatively, you can use a mixture of water and vinegar to combat this.

  5. Sealing/impregnation: After cleaning and complete (!) drying of the boards, it is advisable to apply a sealant or impregnation.
    This protects the boards from future soiling and makes the next cleaning easier.

With this thorough care and regular cleaning, your patio will not only be a visual eye-catcher, but also a durable and safe place for many years to come.

Cleaning joints and removing weeds

The joints of your patio slabs are often susceptible to weeds and dirt.
A joint scraper or a special weed burner can help here.
Remove the weeds regularly to prevent damage to the joints and improve the overall appearance of the patio.

Caution when using the high-pressure cleaner

Care must be taken when cleaning the patio slabs with a pressure washer. Use the appliance on a medium to low setting to avoid damaging the surface.
Especially with natural stone and concrete slabs with a porous surface, it is advisable to adjust the pressure accordingly.

Treat dirt and stains immediately

It is advisable to treat dirt and stains immediately to avoid stubborn stains. Remove organic residues such as leaves and soil regularly and treat stains in the early stages with suitable cleaning agents.

Regular maintenance of the terrace slabs

Regular cleaning and care of the patio slabs is crucial to maintain their beautiful appearance and longevity. Sweep the patio at least once a week and clean it thoroughly as required.
It is also advisable to seal or impregnate the patio slabs, as this makes cleaning much easier because dirt and water no longer adhere to the surface.

Removing stubborn stains

Stubborn stains, such as oil or rust stains, can be particularly difficult to remove. It may be advisable to use special cleaners or seek professional help. Always test new cleaning agents on an inconspicuous area first.
