STEP 4 Secure & Infill

Make any final adjustments and depending on use and traffic patterns, it is recommended to use 4" galvanized spiral deck nails (20D) and fasten every 12" inches along the perimeter edges 1" in from the outside edge of turf. When nailing, be sure to spread the turf away from the nail head so it doesn't trap any fibers and do not to drive the nails too deep (not past flush) which can leave a depression and pull on the turf. Additionally, 3.5" 16D galvanized finish nails can be added internally every 4"-6" on both sides 1" in from each edge, either aligned or alternating (see diagram below). Fluff or brush up the fibers around to cover the nail head, which should disappear in the thatch. 

PaverTURF Nails

Nailing around the pavers will help to secure the turf down and will help keep the turf edges from lifting up when brooming infill sand and preventing clumps of sand catching in-between the edge of the turf strip and paver edge or underneath the turf backing creating bumps . Below is an example of a full nail pattern. You may be okay with less nails or even half the nails depending on your application and use.

NEXT, Infill Play Sand SLOWLY by hand. Add some sand  by broadcasting along the grid lines in either direction, then brush sand against the fiber direction until it stands up evenly and sand is dispersed and not clumped. Be careful not to be too heavy handed (too much / too fast) and bury any fibers which will create an uneven surface. You should be adding enough sand to just below the paver surface throughout.  Repeat this step until desired finish & firmness is achieved. Tip: Use a shop vac to clean up the excess sand on the tiles and re-use.

After brooming everything (to help disperse the sand evenly and to stand up the turf fibers) with a stiff bristle broom against the grain, you can use a leaf blower to help disperse any clumps and to help with clean up.  Lightly spraying with water will also help to seat in the sand once completed. Rain will help this process as well.  You may need to apply sand in a few applications as it settles and you may lose some material with rain over time. Occasional brooming/brushing may be necessary to help keep the fibers from getting crushed in high traffic areas, as well as, adding some sand infill.
