Terraces and facades – care of stone surfaces
Terraces and facades are exposed to the elements year-round. Rain, sun, frost, and organic debris such as leaves or pollen can lead to various deposits. Many types of soiling can be treated with suitable methods.
Common types of pollution
Green coating:
- Algae, moss and lichens
- They develop in damp and shade
- Can make surfaces slippery
Other pollution:
- dirt and dust
- Leaves and organic residues
- Bird droppings
- Weather-related discoloration
Different types of stone and their special characteristics
Concrete and concrete blocks: Robust, relatively easy to maintain
Natural stone (granite, sandstone, slate): Varying sensitivities, observe manufacturer's instructions.
Clinker bricks and tiles: Porous, can absorb moisture
Important: Before cleaning, test the material compatibility in an inconspicuous area.
Cleaning the patio – General procedure
Safety instructions: Wear protective gloves and, if necessary, safety glasses. Consult the safety data sheets for all products used. Ensure the surfaces are slip-resistant.
Basic cleaning
Step 1: Remove coarse dirt
Sweep away loose dirt. Remove moss and weeds mechanically.
Step 2: Apply cleaning agent
Special stone cleaners can be used to clean stone surfaces. Our 500ml stone cleaner can be used for patios, facades, and paving stones. Use the product according to the instructions on the label.
Step 3: Let it take effect
Allow the cleaner to work according to the product instructions. The contact time may vary depending on the degree of soiling.
Step 4: Rinse
Rinse the area thoroughly with water. A garden hose or pressure washer (for suitable materials) can be used.
Note: When using pressure washers, adjust the distance and pressure to the material to avoid damage.
Pressure washer – Instructions for use
High-pressure cleaners can make cleaning easier, but require caution:
- Not suitable for all types of stone (soft stones may be damaged)
- Keep a sufficient distance (at least 30 cm)
- Don't stay in one place for too long.
- Choose a shallow angle
- Grout can be rinsed out.
Tip: Test in an inconspicuous area first.
Special types of soiling
Green growth and moss:
- Remove mechanically (brush, grout scraper)
- Use stone cleaner according to instructions.
- Rinse thoroughly
Oil stains:
- Absorb with binding agent (sand, cat litter).
- Use special degreasers
- Treat repeatedly for stubborn stains
Rust stains:
- Use special rust removers
- Check material compatibility
- Consult a specialist company if necessary.
What should be avoided?
- Overly aggressive cleaners can damage or discolor stone.
- Acidic substances on limestone/marble: Etching the surface
- Excessive pressure from a pressure washer can cause material damage.
- Wire brushes on soft stones: cause scratches
Preventive measures
- Regular sweeping
- Remove leaves promptly
- Ensure good drainage (avoid standing water)
- Impregnation can have a dirt-repellent effect.
- Reduce shading (promotes green growth)
facade cleaning
Facades require special care:
- Check material compatibility
- For multi-story buildings: hire a specialist company.
- Protect windows and doors
- Protect neighboring properties from splashing water
- Obtain permits if necessary.
When professional help might be advisable
In the following cases you should consult a specialist company:
- Large-scale or stubborn soiling
- Sensitive or valuable materials
- Facade cleaning at height
- Uncertainty regarding material compatibility
- Damaged surfaces
Summary
Maintaining terraces and facades requires suitable cleaning agents and material-appropriate methods. With regular maintenance and the right products, stone surfaces can often be well cared for.
For cleaning patios and facades, we recommend our 500ml stone cleaner , which is designed for various stone surfaces. We also offer our 500ml gravestone cleaner for natural stone gravestones.
