Installing artificial turf can transform your outdoor space, but getting the seams right is crucial for a natural look. Artificial Turf Toronto knows that proper seaming techniques make all the difference in creating a flawless lawn.
To seam artificial turf, you’ll need seaming tape, adhesive, and the right tools to join sections smoothly and securely.
Seaming artificial grass isn’t just about connecting pieces – it’s about creating a seamless surface that looks and feels like real grass. Quality seams are invisible and strong, lasting for years without coming apart. With the right steps, you can achieve professional results in your own backyard.
This guide will walk you through the seaming process step-by-step. You’ll learn how to prepare the turf, apply adhesive, and join sections perfectly. Whether you’re tackling a small patch or a large lawn, these tips will help you get great results.
Preparing the Ground
Good ground prep is key for a smooth artificial turf install. It creates a stable base and helps your turf look great for years.
Clearing and Leveling
Start by removing all grass, plants, and roots from the area. Use a shovel or sod cutter to dig down about 7-10 cm. Take out any rocks or debris you find.
Next, level the ground. Use a rake to spread the soil evenly. For larger areas, a plate compactor works well. Aim for a slight slope away from buildings for drainage.
Check your work with a long level. Fix any dips or bumps. A flat surface is crucial for a good-looking turf install.
Laying the Base Material
Add a layer of base material like crushed rock or gravel. This helps with drainage and gives a firm foundation. Spread it about 5 cm thick.
Use a rake to spread the material evenly. Then compact it with a hand tamper or plate compactor. This step is vital for a stable base.
Water the area lightly and compact again. This helps settle the material. Keep adding and compacting until you reach the right height.
Installing a Weed Barrier
A weed barrier stops weeds from growing through your turf. Lay it over the compacted base material. Make sure it covers the whole area.
Overlap the edges by about 10 cm. This stops weeds from sneaking through the seams. Secure the fabric with landscape staples every 30 cm along the edges.
Cut holes for any sprinkler heads or other fixtures. The weed barrier should sit flat with no wrinkles. It’s the last step before laying your turf.
Measuring and Cutting Turf
Getting the right measurements and cuts is key for a great artificial turf install. Proper sizing helps create smooth seams and a flawless look.
Determining Yard Dimensions
Start by measuring your yard’s length and width. Use a long tape measure for accuracy. Write down all the numbers. Add 10-15 cm extra on each side to allow for trimming.
For odd shapes, break the area into rectangles. Measure each part separately. Then add the areas together for the total size.
Don’t forget to account for features like trees or paths. Measure around them carefully.
Double-check all numbers before ordering turf. It’s better to have a bit extra than not enough.
Cutting Turf to Size
Lay out your artificial grass on a flat, clean surface. Stretch it tight to remove wrinkles. Use chalk to mark your cut lines based on yard measurements.
For straight edges, use a sharp utility knife and a straight edge as a guide. Cut from the back of the turf for a cleaner edge.
For curves, use scissors or a carpet knife. Take your time and make small, precise cuts.
When cutting for seams, trim off the manufacturing edge first. This helps create a cleaner join between pieces.
Always cut a bit larger than needed. You can trim more later, but you can’t add back what you’ve cut off.
Securing the Artificial Turf
Proper securing keeps your artificial turf in place and looking great. You’ll need to nail down the edges, apply adhesive, and add infill to create a stable surface.
Nailing Down the Edges
Start by nailing the edges of your turf. Use 5-inch galvanized turf nails every 15 cm along the border. Tuck the turf edge in with a putty knife before hammering. This hides the nails and gives a clean look.
For corners and curves, you may need to place nails closer together. Make sure the nails are flush with the turf backing. Don’t hammer too hard or you could damage the grass blades.
You can also use landscape staples as an alternative to nails. These work well for temporary installations or areas with softer ground.
Applying Turf Adhesive
Turf adhesive creates strong seams and bonds the grass to the base. Fold back the turf edges about 20-25 cm. Apply seam tape down the centre of the join.
Spread a thin, even layer of adhesive on the tape with a notched trowel. Avoid globs or dry spots. The glue will expand as it dries, so don’t use too much.
Press the turf edges into the adhesive. Use a roller to ensure good contact. Let the glue dry fully before walking on the seams.
For large areas, you may need to glue the whole turf to the base. Follow the same process, working in sections.
Adding Infill
Infill adds weight and supports the grass blades. Common infill materials include sand, rubber granules, or a mix of both.
Spread a thin layer of infill over the turf. Use a drop spreader for even coverage. Aim for about 1-2 kg of infill per square metre of turf.
Brush the infill into the grass fibres with a stiff broom. Work in different directions to help it settle. You may need several layers to reach the right depth.
Water the turf lightly to help the infill settle. Let it dry, then add more if needed. The final infill level should be just below the tips of the grass blades.
Seaming Procedures
Proper seaming is crucial for a seamless artificial turf installation. The key steps involve aligning edges and applying seaming tape and glue.
Aligning the Edges
Start by laying out your turf pieces side by side. Make sure the grass blades face the same direction. Trim any excess backing material to create clean edges. Use a sharp utility knife for precise cuts.
Overlap the edges by about 5 cm. This allows you to make final adjustments. Check that the seam lines up perfectly along its entire length. Avoid S-shaped seams, as they can be visible and weaken the installation.
Use landscape pins to hold the turf in place while you work. Space them about 30 cm apart along both sides of the seam. This prevents shifting during the seaming process.
Applying Seaming Tape and Glue
Once your edges are aligned, it’s time to secure them. Roll out seaming tape along the entire length of the seam. The tape should be centred under the overlapped edges.
Apply artificial grass adhesive to the tape. Use a notched trowel to spread it evenly. Work in small sections to prevent the glue from drying before you can join the edges.
Carefully fold the turf edges onto the glued tape. Press down firmly to ensure good contact. Use a roller to apply even pressure along the seam. This helps create a strong bond and reduces the chance of visible seams.
Allow the glue to dry completely before walking on the seam or trimming any excess grass blades. This usually takes 24 to 48 hours, depending on weather conditions.
Finishing Touches and Maintenance
After seaming your artificial turf, a few final steps ensure it looks great and lasts long. Proper drainage and regular care keep your new lawn in top shape.
Ensuring Proper Drainage
Check that water flows away from your turf after seaming. Brush the pile upright with a stiff broom to create a uniform look. This also helps water drain better.
Fill any low spots with extra infill material. This prevents puddles from forming. Use a roller to smooth out bumps and create an even surface.
Install a drainage system if needed. This could be French drains or perforated pipes under the turf. Good drainage stops water from pooling and damaging the seams.
Regular Care
Brush your turf weekly to keep the pile upright. This maintains its natural look and feel. Use a plastic rake or power broom for larger areas.
Remove leaves, twigs, and other debris often. These can block drainage and cause mould growth. A leaf blower works well for this task.
Clean spills quickly to prevent stains. Use mild soap and water for most messes. Rinse thoroughly to avoid soap residue.
Top up infill material yearly. This keeps the turf blades standing up and protects the backing. Use a drop spreader for even coverage.
Avoid heavy objects on the turf. They can crush the pile and damage seams. Use protective mats under furniture legs.
