Scrub the deck clean with environmentally friendly deck cleaner. Rinse with fresh water and leave the deck to dry.
Unroll and lay out the turf. Let it relax for at least at least an hour.
Cut sections of turf to fit the dimensions of the deck, using a utility knife. Add at least two inches in each direction to have some wiggle room.
Spread a layer of turf adhesive for the first section of turf. Spread the adhesive with a notched trowel, if the backing on the turf is smooth. Use a straight trowel if the backing is textured.
Lay the first section of turf on top of the adhesive.
Apply adhesive for the next section. Lay down the second section and butt it together with the first. Squeeze a bead of turf seam sealer along the seam.
Trim excess turf along the edges of the deck with the utility knife.
