Doing a DIY synthetic lawn installation can be a rewarding project that revitalizes your outdoor space into a minimal-effort area that never turns brown. Map out your installation area by taking precise measurements where you want to install the grass and creating a rough layout. This allows you to calculate how much turf to buy and shows potential seam locations. Purchase 5–10% more than estimated to handle irregular shapes.

Next, remove the existing grass and soil using a manual edging tool to eliminate the existing vegetation and a 3-inch depth of subsoil beneath. Ensure full removal of organic matter and obstructions. This step is crucial for achieving a smooth, even surface.

After removing the old lawn, flatten the terrain by raking the earth evenly and a spirit level and straightedge to check for evenness. Fill in low spots with additional soil and Shave down raised areas. Compact the soil using a motorized compactor to avoid future sagging. A firm foundation ensures your synthetic turf remains level and long-lasting.

Add a 1-inch layer of crushed rock about one inch thick for a sturdy sub-base. Spread it uniformly and press it into place. Immediately above the stone layer, add a thin layer of sand, about 12mm, and spread it evenly. The sand helps the tufts to stand 熊本 人工芝 業者 naturally and gives a more natural feel underfoot.

Lay out the synthetic turf on the substrate. Expose it to sunlight for 3+ hours to lie flat naturally. Shave the borders using a carpet knife to fit your space. If you need to join pieces together, use ultra-strong turf seam glue that’s specifically made for artificial grass. Match the seams precisely and roll them down with a seam roller.

Following seam installation, secure the grass around the perimeter using galvanized landscaping spikes spaced every 15–20cm along the edges. Make sure the grass is taut but don’t pull excessively. Maintain distance from joined edges to reduce stress on the fabric.

When the turf is fastened, Apply turf infill evenly like crumb rubber or quartz sand over the surface. Use a broom or a power broom to work the infill down between the blades. It serves multiple purposes to maintain blade upright posture, reduces shifting, and improves durability.

Finally, brush the grass fibers gently with a hard-bristle brush in the natural grain to restore verticality and give a natural look. Remove loose material and spray gently with a hose to settle the infill.

The installation is finished and functional. With correct technique, it can endure 15–25 years with negligible care. Clear organic matter weekly and rake gently every few weeks to preserve their lush look.
