Concrete Patio/Pathway Care Sheet
Congratulations on your new concrete patio or pathway! With proper care, your new concrete surface will provide years of enjoyment and functionality. This in-depth guide will help you understand the essential steps for maintaining its appearance and longevity.
Initial Curing and Protection
The first few weeks after installation are critical for the concrete to reach its full strength.
Avoid Heavy Loads: Do not place heavy furniture, vehicles, or other heavy objects on the concrete for at least 7-10 days, or as advised by your installer. This allows the concrete to cure properly and prevent cracking.
Protect from Stains: During the curing period, avoid spills of oil, grease, or other staining agents. If a spill occurs, clean it immediately.
Regular Cleaning and Maintenance
Regular cleaning is essential to prevent dirt and debris from accumulating and causing stains or deterioration.
Sweeping: Regularly sweep your patio or pathway to remove loose dirt, leaves, and other debris. A soft-bristled broom is usually sufficient.
Hosing Down: Periodically hose down the concrete with a garden hose to remove surface grime. For stubborn dirt, a mild detergent can be used with a scrub brush. Rinse thoroughly afterward.
Pressure Washing: For deeper cleaning, a pressure washer can be used with caution. Set the pressure to a low setting (1200-1500 PSI) and use a wide-angle nozzle to avoid damaging the concrete surface. Maintain a consistent distance from the concrete and avoid directing the spray at one spot for too long.
Stain Removal: Address spills and stains promptly. Different stains require different cleaning methods:
Oil/Grease: Apply an absorbent material like cat litter or sawdust to soak up the fresh spill. For older stains, use a degreaser specifically designed for concrete, following the product instructions.
Mildew/Algae: A mixture of one part bleach to two parts water can be effective. Apply, let sit for a few minutes, scrub, and rinse thoroughly.
Rust: Commercial rust removers for concrete are available. Test in an inconspicuous area first.
Sealing Your Concrete
Sealing your concrete patio or pathway is highly recommended to protect it from stains, water penetration, and freeze-thaw cycles. Most plain or standard concrete is not sealed, which leads to water absorption and that allows earlier staining (i.e. mildew and mold growth), and earlier deterioration, especially on the surface (i.e., spalling and surface cracking). It is critical that you seal decorative concrete such as stamped concrete, textured concrete and exposed aggregate concrete. Go to our Stamped Concrete Care Page for that information.
When to Seal: Typically, new concrete should be sealed after it has fully cured, which can take 28 days or more. Consult with your installer and/or sealer manufacturer for their specific recommendations.
Types of Sealers:
Penetrating Sealers: These seep into the concrete, providing excellent protection without altering the surface's appearance. They are durable and long-lasting.
Topical Sealers: These form a protective film on the surface, often enhancing the color and providing a glossy or matte finish. They may require reapplication more frequently.
Application:
Clean the Surface: Ensure the concrete is thoroughly clean and dry before applying the sealer.
Apply Evenly: Apply the sealer according to the manufacturer's instructions, typically using a roller or sprayer. Avoid puddling.
Multiple Coats: Some sealers require multiple thin coats for optimal protection.
Frequency: Reapply sealer every 2-5 years, depending on the type of sealer used, traffic, and environmental conditions. You can test if your concrete needs re-sealing by pouring a small amount of water on the surface; if it soaks in rather than beading up, it's time to reseal.
Winter Care
Proper winter care is crucial to prevent damage from ice and snow.
Snow Removal: Determine the type of tools you want to use when removing snow or when hiring a service company. Plastic shovels and snowblowers with rubber blades are an option to prevent surface scratching; however, you will need to request this if you are hiring a snow contractor. Surface scratches will fade over time, and many property owners with older concrete are not concerned with minor surface scratches. This is why you often see snow removal equipment with metal blades, which maximize proficiency in the snow removal process.
De-Icers: Use caution when choosing de-icing products. Avoid de-icers containing ammonium sulfate or ammonium nitrate, as these can chemically attack and damage concrete. Products containing calcium chloride or magnesium chloride are generally safer, but always use them sparingly and rinse the area thoroughly once the ice has melted. Sand can also be used for traction. When hiring a professional, talk about the options if surface wear is important to use. Professional companies are more concerned with safety and the liability of slippery surfaces than wear and deterioration of the concrete surface, so be sure to communicate your desires if you want specific products used or not used. See the Stamped Concrete Care Page for more information as the above information is for plain or standard concrete.
General Tips and Considerations
Heavy Objects: When moving heavy objects or furniture, lift them rather than dragging them across the concrete to prevent scratches. Scratches on plain concrete will fade over time but you may still see them.
Cracks: Minor hairline cracks are common in concrete and are usually not a cause for concern. Larger cracks, however, should be assessed by a professional.
Professional Help: For significant damage, extensive cleaning, or professional sealing, consider contacting a concrete specialist.
By following these guidelines, you can ensure your plain concrete patio or pathway remains a beautiful and functional addition to your property for many years to come.
