Used it to lay 1/2" bamboo decks at 55-60psi and they worked well with very little tongue gaps on the boards. This made the process a lot easier than using a hand nailer (not that anyone in their right mind would use a hand nailer to work an entire floor.) I particularly liked the hammer that comes with the kit which was the non-rubberized side great for setting the boards., it also quickened the transition from installing the boards to nailing them in as I didn't have to change hammers.boards.The kit comes with several options for spacers to accommodate different width floors and an adjustable leg to accommodate the Getting nailers flush to the floor took me a few adjustments to get it just right but all in all it only took 5 minutes one man ko: Aligning the nail edge to the board spring took multiple tries and a lot of visual focus to keep it from slipping over the edge onto the top of the board. Be sure to practice and take a good look at where you need to line it up. Flooring says you can do about 1,000 square feet a day, which is WAY too optimistic for anyone who has never laid floors. It took us about 6 hours to dismantle and prepare the floor without much leveling of the floor. It took another 3-4 days for more than 10 hours of work to lay the boards.
