Staple guns now pack sufficient power to go through just any type of wood surface. Ranging from softwood such as juniper, pine, and cedar to hardwoods like alder, Balser, and beech, staple guns can be used to fasten a piece of fabric to these surfaces. However, as you buy your staple gun, it is important to buy a type well suited for the density or hardness you want to use it for. For very hardwood surfaces, it is generally best to use big sized pneumatic staple guns.
