Choosing the Right Synthetic Turf for Your Space
Before you pick up a shovel, you need to select the right product for your specific needs. Not all synthetic turf is created equal, and the choice depends heavily on how you use your garden.
For high-traffic areas where kids and pets play, look for a durable pile with a high density. A shorter pile height, typically between 25mm and 30mm, is often easier to clean and stays upright longer under heavy use.
If you are looking for a purely aesthetic, “show garden” look, you might prefer a longer pile of 35mm to 40mm. These longer blades offer a softer, more luxurious feel underfoot but may require more frequent brushing to prevent flattening.
Understanding Pile Direction
Every roll of synthetic turf has a “grain” or pile direction. This is the slight angle at which the blades of grass lean. For the best look, the pile should always face toward your house or the main viewing point.
When the grass leans toward the viewer, it looks fuller and more natural. If it leans away, you might experience a slight “sheen” or glare from the sun, which can make the lawn look artificial.
Backing Materials and Drainage
Check the backing of your chosen turf. Most high-quality options feature a perforated backing that allows water to drain through into the soil below. This is essential for preventing puddles during heavy rain.
If you have pets, consider a polyurethane (PU) backing rather than latex. PU backings don’t absorb moisture or odors as easily, making them a much better choice for a fresh-smelling garden over time.
Essential Tools and Materials for Success
Preparation is the key to a professional finish. Having the right tools on hand will save you time and prevent unnecessary frustration during the installation process.
You will need a heavy-duty turf cutter or a sharp spade to remove your existing lawn. For the sub-base, a vibrating plate (often called a wacker plate) is non-negotiable for achieving a flat, stable surface.
For the layout and cutting, ensure you have a sharp utility knife and plenty of spare blades. Synthetic turf is tough, and a dull blade will result in jagged edges and visible gaps between your sections.
The Shopping List
- Geotextile Weed Membrane: To prevent unwanted growth from pushing through your new lawn.
- Crushed Stone or MOT Type 1: This creates a solid, draining base.
- Grano Dust or Sharp Sand: Used for the final leveling layer.
- Joining Tape and Adhesive: Specifically designed for outdoor synthetic turf.
- U-Pins or Galvanized Nails: To secure the perimeter of the grass.
- Silica Sand: Used as an infill to weigh the grass down and keep the blades upright.
Safety First
When working with heavy materials like crushed stone, always wear protective gloves and sturdy boots. If you are using a vibrating plate, ear protection and eye goggles are highly recommended to stay safe.
If you encounter large tree roots or underground utility lines while excavating, stop immediately. It is better to consult a professional than to risk damaging your home’s plumbing or electrical systems.
Preparing the Ground: The Secret to Longevity
The most common mistake beginners make is rushing the ground preparation. Your fake lawn is only as good as the foundation it sits on. If the ground is uneven, the grass will eventually sag and look bumpy.
Start by removing the existing sod to a depth of about 75mm to 100mm. This provides enough room for your sub-base layers. Ensure you remove any large stones or organic debris that could rot over time.
Once the area is clear, install your edge restraints. You can use treated timber, plastic edging, or even a concrete haunch. This keeps the sub-base contained and gives you a solid point to secure the grass edges later.
Installing the Sub-Base
Before laying fake grass, you must build a solid foundation using crushed stone. Spread a layer of MOT Type 1 or similar aggregate to a depth of roughly 50mm to 70mm.
Use your vibrating plate to compact this layer thoroughly. You want a surface that feels like solid rock. If you skip this step, the ground will shift over time, leading to unsightly dips and trip hazards in your lawn.
After the base is compacted, add a 20mm layer of grano dust or sharp sand. This “screed” layer allows you to smooth out any minor imperfections. Use a long straight edge to level it off perfectly.
The Importance of the Membrane
Lay your weed membrane directly over the compacted sub-base. Some people prefer putting it under the stone, but placing it just beneath the grass is more effective at preventing airborne seeds from rooting in the sand infill.
Overlap the edges of the membrane by at least 100mm and secure it with a few pins. This creates a protective barrier that keeps your lawn looking pristine for years without the need for chemical weed killers.
The Step-by-Step Process of laying fake grass
Now comes the exciting part! Unroll your synthetic turf and lay it over the prepared area. It is a good idea to let the grass “relax” for at least two to four hours before cutting it.
This relaxation period allows any wrinkles from the roll to flatten out. It also lets the backing material acclimate to the outdoor temperature. If you cut it immediately, the grass might shrink or expand later, ruining your perfect fit.
Position the grass so that the pile direction is facing your house. If you need multiple rolls, ensure the pile direction is identical on every piece. If one roll is reversed, the two sections will look like completely different colors.
Trimming to Fit
When trimming the edges, always cut from the back of the turf. This allows you to see the “stitch lines” (the rows where the grass blades are sewn into the backing). Cutting between these rows ensures a cleaner finish.
Leave about 5cm of excess grass around the perimeter initially. You can do the final, precise trimming once the main body of the lawn is positioned and any joins are completed. Take your time—measure twice and cut once!
Use a sharp knife and change the blade frequently. A fresh blade glides through the tough backing like butter, giving you the cleanest possible edge against your paving or garden borders.
Perfecting the Seams and Securing the Edges
Creating an invisible join is the hallmark of a professional installation. If you have a wide garden, you will likely need to join two or more widths of grass together. This requires patience and a steady hand.
Start by trimming the factory edges off both rolls. You should cut in about two or three “stiches” to ensure you are working with a clean, flat surface. Lay the two pieces side-by-side to check the fit before applying any glue.
The gap between the two pieces should be consistent—usually about 2mm to 3mm. If the pieces are too close, the grass will “peak” at the seam. If they are too far apart, you will see a visible line in the lawn.
Applying the Adhesive
Fold back the edges of both pieces of grass and lay your joining tape down the center of the gap. The shiny side of the tape should face down, with the fabric side facing up to receive the glue.
Apply the specialist turf adhesive in a zigzag pattern along the tape. Use a notched spreader to ensure even coverage. Be careful not to get any glue on the grass blades, as it is very difficult to remove once it cures.
Carefully fold the grass edges back onto the tape. Once they are in place, walk along the seam to press the backing firmly into the adhesive. Avoid heavy traffic on the seam for at least 24 hours while the glue sets.
Securing the Perimeter
Once the joins are set, it’s time to secure the outer edges. Use galvanized U-pins or nails every 15cm to 20cm along the perimeter. If you used a timber frame, you can screw the grass directly into the wood.
Tuck the edges of the grass down into the gap between your sub-base and the edging for a neat, tucked-in finish. This prevents the edges from lifting and keeps the lawn looking like it grew naturally in that space.
Adding the Finishing Touches: Infill and Brushing
The final step in laying fake grass is the application of kiln-dried silica sand infill. Many people think the sand is just to keep the grass down, but it actually serves several vital purposes.
The sand supports the base of the grass blades, helping them stay upright even after you walk on them. It also acts as a protective layer for the backing, shielding it from UV rays and extending the lifespan of your lawn.
Spread the sand evenly across the surface using a drop spreader or by hand. You typically need about 5kg to 8kg of sand per square meter, depending on the pile height of your grass.
The Final Brush-Up
Once the sand is spread, use a stiff broom or a power brush to work it deep into the pile. Brush against the grain of the grass to lift the blades and settle the sand at the bottom.
You will notice an immediate difference. The grass will look fuller, more upright, and much more natural. This mechanical brushing is the best way to get that professional, “just installed” look that neighbors will envy.
Don’t worry if you see a little bit of sand on the surface initially. After a few rain showers or a quick spray with a hose, the sand will settle completely, leaving you with a perfectly manicured lawn.
Long-Term Care for Your New Lawn
One of the best things about synthetic turf is how little work it requires compared to real grass. However, “low maintenance” doesn’t mean “no maintenance.” A little care goes a long way in keeping it beautiful.
Use a leaf blower or a plastic rake to remove leaves and organic debris regularly. If left to rot, these materials can create a nutrient-rich environment where weeds might eventually try to grow in the sand infill.
If you have pets, solid waste should be removed as usual. You can wash down the area with a mixture of water and mild detergent or a specialist enzyme cleaner to keep the lawn smelling fresh and hygienic.
Dealing with Flattening
Over time, high-traffic paths may start to look a little flat. This is perfectly normal. Simply give the area a quick brush with a stiff broom to revive the fibers and bring them back to life.
Avoid placing heavy items like inflatable pools or heavy garden furniture in the same spot for months at a time. If you do move them, a good brushing will usually restore the pile, but permanent crushing can occur over very long periods.
Finally, keep hot items like charcoal grills or fire pits away from the grass. While modern synthetic turf is fire-retardant, the plastic blades can melt if exposed to extreme heat or fallen embers.
Frequently Asked Questions About laying fake grass
Is fake grass safe for dogs and cats?
Absolutely! High-quality synthetic turf is non-toxic and very durable. Most pets love the soft feel of the grass. Just ensure you choose a product with good drainage and consider using a PU backing for better odor control if your pets use the lawn frequently.
How long does a synthetic lawn typically last?
When installed correctly with a solid sub-base, a high-quality synthetic lawn can last anywhere from 12 to 20 years. The lifespan depends on the quality of the product, the amount of foot traffic it receives, and how well it is maintained over the years.
Can I install synthetic turf directly on top of soil?
It is not recommended. Installing directly on soil often leads to an uneven surface as the ground settles. Furthermore, the grass will not drain properly, leading to mud and hygiene issues. Always use a compacted stone sub-base for the best results.
Does fake grass get hot in the summer?
Synthetic grass can become warmer than natural grass in direct sunlight. However, it rarely gets hot enough to cause discomfort. On exceptionally hot days, a quick spray with a garden hose will cool the surface down instantly for children and pets.
Conclusion
Transforming your garden by laying fake grass is a fantastic investment that pays off in both property value and personal time. No more Saturday mornings spent behind a noisy lawnmower or worrying about brown patches during a summer heatwave.
By following these steps—focusing on a rock-solid foundation, careful seaming, and the right finishing touches—you can create a professional-grade outdoor space that looks stunning year-round. Remember, the secret is in the preparation!
Take your time, enjoy the process, and soon you’ll have the perfect green sanctuary to relax in. Go forth and grow (or in this case, lay) your dream garden today!
