How to put artificial grass
To put artificial grass, prepare the base by excavating, adding and compacting a gravel layer, and then a sand layer. Roll out the turf, cut to fit, and secure the edges with stakes or adhesive, infilling with sand or rubber granules for stability and appearance.
Installing artificial grass yourself is a rewarding project that can transform your yard. The process involves several key stages, from site preparation to final finishing touches. Proper preparation is crucial for drainage and longevity.
Begin by defining the area for your artificial grass. Remove any existing vegetation, sod, or debris. For a typical installation, you’ll need to excavate the area to a depth of about 3 to 4 inches to accommodate the base layers. Ensure the excavated area slopes slightly away from any structures to promote water runoff.
Next, lay down a layer of crushed gravel, typically 1 to 2 inches thick. This layer is vital for drainage. Compact this gravel thoroughly using a plate compactor. This creates a stable foundation and prevents settling over time. Over the compacted gravel, add a thinner layer of coarse sand, about 1 inch deep. This sand layer provides a smoother surface for the turf and helps keep the blades standing upright.
Once the base is prepared and compacted, it’s time to lay the artificial turf. Carefully unroll the turf over the prepared area. Allow the turf to relax in the sun for a couple of hours; this helps remove wrinkles and makes it easier to handle. Trim the edges precisely using a sharp utility knife, following the contours of your area. Ensure a snug fit against any borders.
To secure the turf, you can use galvanized steel stakes driven through the turf backing into the ground, spaced about every 6 to 12 inches around the perimeter. Alternatively, a specialized artificial grass adhesive can be used along the edges, especially for installations on concrete or if you want a very clean finish. For larger areas, you might need to join seams. Overlap the seams by about 1 inch, then trim one edge so they meet perfectly. Use seam tape and adhesive specifically designed for artificial turf to join them securely.
The final step is infilling. Spread a layer of infill material, such as kiln-dried sand or specialized rubber granules, evenly across the surface. Use a stiff-bristled broom or a power brush to work the infill down into the turf blades. This infill helps the blades stand up, adds weight to keep the turf in place, and protects the backing from UV degradation. A light watering can help settle the infill.
Preparing the base for artificial grass
A solid base is the cornerstone of any successful artificial grass installation. It ensures proper drainage, prevents weed growth, and provides a stable surface that won’t settle or shift. The standard base consists of two layers: crushed gravel and sand.
Start by excavating the designated area to a depth of 3 to 4 inches. This depth allows for a 1-2 inch gravel layer and a 1-inch sand layer, plus the thickness of the turf itself. Ensure the excavated area has a slight slope, about 1/4 inch per foot, directing water away from buildings and towards drainage points.
The first layer is crushed stone or gravel, typically 3/4-inch minus or similar aggregate. Spread this evenly to a depth of 1 to 2 inches. Crucially, compact this layer using a plate compactor until it’s firm and level. This compacted gravel layer provides excellent drainage and a stable sub-base.
The second layer is coarse sand, usually 1 inch deep. This sand layer acts as a cushion and a smoother surface for the turf backing. Spread it evenly and then screed it smooth. While some installers skip this, it aids in achieving a flat finish and makes the turf feel softer underfoot. Compact the sand layer lightly, just enough to set it in place without making it rock hard.
For areas prone to significant rainfall or with heavy foot traffic, consider adding a layer of landscape fabric before the gravel. This acts as a weed barrier and helps keep the layers separate, though good compaction usually suffices for weed prevention.
Cutting and seaming artificial grass
Accurate cutting and seamless joining are vital for a professional-looking artificial grass installation. Take your time with these steps to avoid visible seams or uneven edges.
Once the turf is unrolled over the prepared base, let it acclimate to the temperature for at least an hour. This helps reduce wrinkles and makes cutting easier. Start by cutting along the edges of your area, leaving a small overlap (about 3-4 inches) around the perimeter. Use a sharp, heavy-duty utility knife with fresh blades. Cut from the back of the turf whenever possible for cleaner lines.
For seaming two pieces of turf together, you’ll want to create a butt seam where the edges meet perfectly. Overlap the two pieces by about 1 inch and carefully trim both edges so they meet exactly. Ensure the turf pile direction is consistent on both pieces before cutting.
For seaming, you have a few options. The most durable method involves using artificial grass seam tape and a specialized adhesive. Apply the adhesive to the seam tape, then carefully lay the tape along the seam line on the prepared base or a thin layer of sand. Lay the trimmed edges of the turf onto the tape, pressing firmly to ensure adhesion. Work in small sections if needed.
Another method for smaller areas or less critical seams is to simply pin the edges together using landscape spikes. However, for high-traffic areas or a truly seamless look, adhesive and tape are recommended. Always ensure the turf blades are not caught in the seam adhesive.
Securing and infilling artificial grass
Properly securing the artificial grass prevents it from shifting or lifting, while infilling provides stability, improves appearance, and enhances durability.
After cutting and positioning the turf, secure the perimeter. For installations on soil or gravel bases, use 6-inch galvanized steel spikes. Drive these spikes through the turf backing into the ground approximately every 6-12 inches around the entire edge. You can also place them along any seams for extra security.
If installing on concrete, securing is often done with a strong construction adhesive or specialized artificial grass adhesive applied around the perimeter and along seams. Ensure the concrete surface is clean and dry before applying adhesive.
Infilling is done after the turf is secured. The most common infill is kiln-dried play sand, which is clean and has a consistent grain size. Other options include rounded pea gravel, crumb rubber (for sports fields), or specialized antimicrobial infills. The amount of infill needed varies by turf type but is typically 1-2 pounds per square foot.
Spread the infill evenly across the turf surface using a drop spreader or by hand. Then, use a power broom or a stiff-bristled push broom to brush the infill down into the turf pile. This process may need to be repeated a couple of times to ensure the infill is distributed evenly and reaches the base of the turf blades. A light watering can help settle the infill and blades.
Common Mistakes When Installing Artificial Grass
| Step | Typical Mistake | How to Avoid It |
|---|---|---|
| Base Preparation | Insufficient Compaction | Use a plate compactor thoroughly after adding gravel. Ensure the base is firm and level. |
| Drainage Layer | Skipping or inadequate gravel layer | Always install a 1-2 inch layer of crushed gravel and compact it well. Ensure a slight slope away from structures. |
| Cutting Edges | Jagged or uneven cuts | Use a sharp utility knife with fresh blades. Cut from the back of the turf for precision. |
| Seaming | Visible seams or poor adhesion | Use specialized seam tape and adhesive. Ensure turf pile direction matches and edges meet perfectly. |
| Securing Edges | Turf lifting or shifting | Use galvanized stakes every 6-12 inches around the perimeter and along seams, or use appropriate adhesive on concrete. |
| Infilling | Uneven infill or not enough | Spread infill evenly and use a power broom or stiff brush to work it into the turf pile. Follow turf manufacturer’s recommendations for infill depth. |
