The edges of an artificial turf installation are where most DIY installs reveal themselves. Visible gaps, lifted corners, and turf that creeps away from borders over time are all edge problems that experienced installers avoid with a few reliable techniques. Here is what the pros do.
Bender Board Is Not Optional
Bender board is the flexible plastic or composite border material that runs along every perimeter edge of a turf installation. It serves as a nailing surface for securing the turf edge and creates a clean, defined transition between the turf and adjacent surfaces. Skipping it or substituting with inadequate alternatives is the most common source of edge failure.
Bender board needs to be staked firmly into the base at regular intervals. The turf edge is then nailed through the backing and into the bender board. This creates a mechanical connection that holds the edge down even under foot traffic, wind, and the expansion and contraction of temperature changes.
Nail Spacing Matters
Standard nail spacing for turf edges is every six to ten inches. For pet areas or any installation where digging or pulling is a concern, go down to four to six inches. Use galvanized nails to prevent rust bleeding through the turf backing over time.
At corners, use extra nails clustered tightly. Corners experience more stress than straight runs and they are where lifted edges almost always start.
Transitions to Hardscape
Where turf meets concrete, pavers, or other hard surfaces, the turf edge needs to tuck cleanly against the hardscape rather than sitting on top of it. Depending on the hardscape material, this might mean cutting a channel to recess the bender board or using adhesive to bond the turf edge directly to the adjacent surface.
A visible gap between turf and hardscape is both an aesthetic problem and a practical one: it traps debris, allows weed growth, and is a tripping hazard. Take the time to get this transition right.
Matching Grade at Borders
The base height at the turf perimeter should allow the finished turf surface to match the height of adjacent surfaces. Turf that sits significantly higher or lower than a neighboring patio or walkway looks unprofessional and creates a trip hazard. This is a base preparation issue that needs to be addressed before the turf goes down, not after.
