Measure the size of the area to make sure you buy the right amount of synthetic turf. It's also important that the ground that you want to lay the turf on is smooth and flat. Laying turf is a two person job, so ask someone to help you with this project.
After pegging in the first length of turf, roll out the second. Use the utility knife to cut the turf longer than it needs to be, you will trim it to size later.
To cut around an obstruction, such as a tree, measure the overlap and mark that distance out on the turf. Cut the turf that distance then pull it around the tree and butt the two sides together. Then cut around the tree border. If you don't have a border to use as a cutting guideline, use a straight edge and the knife.
Roll out the adhesive joining tape on top of the turf and cut it to size. Fold back the edges of both pieces of turf where they need to be joined. Peel the backing paper off the adhesive tape. Put half of the tape under the edge of the first length of turf you laid. Move down the length of the turf and press it down so it sticks to the adhesive tape. Move the second length of turf next to the first and move down the turf, sticking it down. Make sure the blades of grass are running in the same direction. Cut the turf to size at the ends. Use the hammer and pegs to secure the turf around the edges.
