Artificial grass has become increasingly popular for homeowners and businesses seeking low-maintenance landscaping solutions. This synthetic turf offers a lush, green appearance year-round without the need for watering, mowing, or fertilizing. However, proper installation requires knowing how to cut artificial grass accurately for a polished, professional look.
Cutting artificial grass correctly ensures a seamless fit and attractive finish for your outdoor space. Whether you're installing turf for a small patio area or covering a large yard, understanding the right techniques and tools for cutting synthetic grass is essential. With the proper methods, you can achieve clean edges, smooth curves, and precise cuts around obstacles to create a beautiful and long-lasting artificial lawn.
1) Measure the Area
Before cutting artificial grass, accurately measure the installation area. Start by sketching a rough outline of the space on paper.
Use a measuring tape to determine the length and width of the area. For rectangular spaces, multiply these measurements to calculate the total square footage.
If your area has curved or irregular shapes, divide it into smaller rectangles or triangles. Measure each section separately and add them together for the total.
Remember to account for any obstacles like trees, flower beds, or patios. Measure around these to ensure you have enough turf to cover the entire space.
Add an extra 10% to your final measurement to account for waste and trimming. This ensures you have enough material to work with during installation.
Write down all measurements clearly. Double-check your calculations to avoid ordering too much or too little artificial grass.
2) Clear the Ground
Before cutting artificial grass, you need to prepare the area. Remove any existing grass, weeds, or debris from the surface. This ensures a clean, flat base for your new turf.
Use a spade or turf cutter to remove old grass and roots. Rake the area thoroughly to eliminate smaller debris and loose soil. Level any uneven spots with additional soil or sand.
Check for rocks, sticks, or other objects that could create bumps under your artificial grass. Remove these to maintain a smooth surface. Fill in any holes or depressions to create an even foundation.
Compact the soil using a plate compactor or hand tamper. This step prevents future settling and keeps your artificial grass level. Apply a weed barrier fabric if desired to inhibit weed growth beneath the turf.
Ensure proper drainage by creating a slight slope away from buildings or structures. This prevents water from pooling on your artificial grass. A well-prepared ground makes cutting and installing your new turf much easier.
3) Install a Weed Barrier
Before laying artificial grass, it's crucial to install a weed barrier. This step prevents unwanted plants from growing through your new turf.
Choose a high-quality, permeable weed barrier fabric. This material allows water to drain while blocking weeds from penetrating the surface.
Roll out the weed barrier across your prepared base. Make sure it covers the entire area where you plan to install the artificial grass.
Overlap the seams of the fabric by at least 6 inches to ensure complete coverage. This prevents gaps where weeds could potentially grow.
Secure the edges of the weed barrier with landscaping staples or nails. Place them every few feet to keep the fabric in place.
Trim any excess fabric around the perimeter of your installation area. Leave a small overhang to tuck under the edges of your artificial grass later.
By installing a weed barrier, you create a protective layer between the soil and your new turf. This helps maintain the integrity and appearance of your artificial grass for years to come.
4) Add a Base Layer
Before laying artificial grass, you need to create a stable foundation. Start by removing any existing vegetation and soil to a depth of about 3-4 inches.
Apply a weed killer to prevent future growth. This step is crucial for maintaining a weed-free surface beneath your artificial turf.
Add a layer of crushed rock or decomposed granite as your base material. Spread it evenly across the area, aiming for a thickness of about 2 inches.
Use a plate compactor or hand tamper to compress the base layer firmly. This ensures a solid foundation that will prevent sinking or unevenness in your artificial grass.
Level the surface carefully using a rake or straight edge. Check for any low spots or bumps and adjust as needed. A smooth, even base is essential for a professional-looking result.
Consider adding a layer of sand on top of the compacted base for improved drainage. Spread it thinly and evenly, then compact it again to create a firm, level surface ready for your artificial grass.
5) Compact the Base
Before cutting your artificial grass, it's crucial to properly compact the base. This step ensures a stable foundation for your turf installation.
Use a vibratory plate compactor to achieve an even and solid surface. Start by spreading a 2-3 inch layer of base material, such as decomposed granite or gravel, over the prepared area.
Run the plate compactor over the surface in multiple directions. This helps eliminate air pockets and creates a firm base. Pay extra attention to the edges and corners of your installation area.
For optimal results, compact the base in stages. Add thin layers of material and compact each one before moving on to the next. This method produces a more stable foundation than compacting a single thick layer.
After compaction, check the surface for any remaining low spots or irregularities. Fill these areas with additional base material and compact again as needed. A level base is essential for a smooth artificial grass installation.
6) Lay the Artificial Grass
Start by unrolling the artificial grass across your prepared surface. Position it carefully, ensuring the blades face in the desired direction.
Allow the grass to settle for a few hours before securing it. This helps eliminate wrinkles and allows the material to acclimate to its new environment.
Begin securing the grass at one end using lawn staples or adhesive, depending on your base material. Work your way across, smoothing out any bumps or folds as you go.
Pay special attention to the edges, ensuring they are firmly attached and properly aligned. Use a carpet tucking tool to tuck the edges into any border areas for a clean finish.
If using multiple pieces, align the seams carefully. Join them using seam tape and adhesive for a seamless look.
Trim any excess grass along the edges with a sharp utility knife. Make slow, careful cuts for the best results.
Finally, brush the grass fibers upright using a stiff-bristled broom. This helps blend any seams and gives the turf a natural, uniform appearance.
7) Trim the Edges
After laying your artificial grass, trimming the edges is crucial for a polished look. Start by using a sharp utility knife with a fresh blade for clean cuts. Run the knife along the perimeter, following the contours of your installation area.
For straight edges, use a metal straight edge as a guide to ensure precision. When dealing with curves or irregular shapes, take your time and cut freehand, making small, controlled cuts.
Pay attention to areas around fixtures or obstacles. Cut carefully around posts, trees, or other features in your yard. Make sure to leave a small gap for expansion.
Brush the pile of the grass open after cutting to reveal any uneven areas. Trim any stray fibers for a neat appearance. Double-check your work to ensure all edges are smooth and even.
Remember to dispose of any grass trimmings properly. Sweep the area to remove loose fibers and maintain a tidy workspace. With careful edge trimming, your artificial grass installation will look professional and seamless.
8) Secure the Grass
After cutting your artificial grass, it's crucial to secure it properly. Start by using seaming tape and adhesive along the edges where pieces meet. This ensures a seamless look and prevents lifting.
For installations on soil, use landscape pins or staples every 6-8 inches along the perimeter. Drive them in at a slight angle for better hold. In high-traffic areas, place additional pins for extra stability.
When installing on concrete, apply a strong outdoor adhesive to the surface before laying the grass. Use a trowel to spread it evenly, then press the turf firmly into place.
For wood surfaces, secure the grass with galvanized nails or screws along the edges. Ensure they're countersunk to avoid any protrusion.
Once secured, use a power broom or stiff brush to brush the fibers upright. This helps distribute the infill material and gives your artificial grass a natural, uniform appearance.
Remember to leave a small gap around fixed objects like trees or posts to allow for expansion and contraction. Trim any excess carefully with a sharp utility knife for a clean finish.
9) Brush the Grass Fibers
After cutting your artificial grass, brushing the fibers is an essential step. This process helps restore the grass's natural appearance and ensures proper fiber orientation.
Use a stiff-bristled push broom to brush the grass fibers. Work against the natural pile direction to lift the blades and remove any debris that may have accumulated during cutting.
Choose a hot, dry day for brushing if possible. The heat helps the grass fibers stand up and return to their intended shape more easily.
Start at one end of your newly cut area and work your way across systematically. Apply firm, consistent pressure as you brush to achieve uniform results.
Pay extra attention to areas near edges or seams where fibers may have been flattened during the cutting process. Brushing these spots thoroughly will help blend them seamlessly with the rest of the turf.
Remember to brush your artificial grass regularly after installation to maintain its appearance and prolong its lifespan. This practice keeps the fibers upright and prevents matting over time.
10) Add Infill
Once you've cut and installed your artificial grass, it's time to add infill. This crucial step helps maintain the turf's appearance and performance.
Start by selecting an appropriate infill material. Common options include silica sand, crumb rubber, or specialized artificial grass infill products.
Calculate the amount of infill needed based on your turf's square footage. A general guideline is 1.5 to 2.5 pounds per square foot, but check your manufacturer's recommendations.
Spread the infill evenly across the turf using a drop spreader or by hand. Work in small sections to ensure uniform coverage.
Use a stiff brush or power broom to work the infill into the grass fibers. Brush in multiple directions to help the infill settle between the blades.
Continue adding layers of infill and brushing until you reach the desired depth. This process helps the grass blades stand upright and provides stability.
After applying the infill, give your artificial grass a final brushing to ensure an even distribution and natural appearance.
Preparation for Cutting Artificial Grass
Proper preparation is crucial for achieving clean, precise cuts when trimming artificial grass. A well-planned approach ensures accuracy and minimizes waste.
Measuring the Area
Measure the installation area carefully using a tape measure. Record the length and width, accounting for any curves or obstacles. Add an extra 50-100mm to each edge for trimming.
Create a detailed sketch of the space, noting dimensions and any features like trees or patios. This diagram will guide your cutting process.
Double-check all measurements to avoid costly mistakes. For complex shapes, consider making a paper or cardboard template first.
Gathering Necessary Tools
Collect essential tools before starting:
Sharp utility knife or carpet cutter
Spare blades
Straight edge or metal ruler (at least 1 meter long)
Chalk line or marking spray
Heavy-duty scissors
Measuring tape
Protective gloves
Ensure all cutting tools are sharp for clean cuts. Dull blades can snag or tear the turf backing.
Consider renting a turf cutter for large areas or long straight cuts. This tool can save time and improve precision.
Safety Precautions
Wear protective gear:
Cut-resistant gloves
Safety glasses
Knee pads (if kneeling)
Dust mask (if cutting indoors)
Work in a well-ventilated area, especially if using adhesives. Keep your workspace clean and free of tripping hazards.

Take breaks to avoid fatigue, which can lead to accidents. Stay hydrated, particularly when working outdoors.
Best Practices for Cutting Artificial Grass
Properly cutting artificial grass is crucial for achieving a professional-looking installation. Using the right tools and techniques will ensure clean edges, seamless joins, and a flawless finish.
Cutting Techniques
Start with a sharp utility knife or carpet cutter for precise cuts. Change blades frequently to maintain sharpness. Use a straight edge or chalk line as a guide for long, straight cuts. Make multiple passes, scoring lightly at first and then cutting deeper with each pass. This approach prevents tearing and ensures a clean edge.
For curved cuts, use a sharp carpet knife and make small, careful incisions following your marked line. Take your time and work in sections. Consider using templates for complex shapes or patterns.
Always cut from the back of the turf when possible. This protects the visible fibers and creates a cleaner edge. Cut in the direction of the pile to maintain a natural look.
Trimming Edges
Trim excess material after laying the main sections. Use sharp scissors or a carpet knife for detailed edge work. Cut close to obstacles like trees or posts, leaving a small gap for expansion.
For a neat finish along walls or borders, use a sharp utility knife and a metal straight edge. Press firmly and cut in one smooth motion. Trim any stray fibers with scissors for a tidy appearance.
Consider using an edging tool designed specifically for artificial grass. These tools can create a consistent, professional-looking edge quickly and easily.
Seaming and Joining Sections
When joining sections, opt for an S-shaped or serpentine cut along the seam. This technique helps hide the join and creates a more natural appearance. Overlap the sections slightly, then cut through both layers simultaneously for a perfect match.
Use seaming tape and adhesive to join sections. Apply the tape under the seam and spread adhesive evenly. Press the edges together firmly and allow sufficient drying time.
For large areas, stagger the seams to reduce their visibility. Avoid placing seams in high-traffic areas where they may separate over time. Brush the fibers along the seam to blend them seamlessly.
