We recently completed a conversion of our two car garage into music space. We hired a contractor to level the floor, upgrade the electrical service, install insulation and sheetrock, and HVAC, including a ductless mini-split and a direct vent gas fireplace. The contractor left us "ready for paint", which means we did all the priming, painting, wood finishing, flooring and, of course, the pallet walls. There are two pallet walls, one is about 20 feet by 8 feet, the other is about 10 feet by 8 feet. We took apart about 70 pallets, took out all the fasteners, and sanded the ends, sides, edges, and the side that is showing on the wall. We painted both pallet walls with dark brown paint to give any gaps a more natural look. The pallets were fastened to the wall with a pneumatic brad nailer into a double layer of 5/8-inch sheet rock with Green Glue sandwiched between the layers for sound reduction.
