Things You'll Need

Instructions

1

Locate and mark all the studs in each wall you want to cover with pine, using an electronic stud finder. Mark out the studs with a pencil and level, with vertical lines up the walls.
2

Mark a horizontal line over the base of the wall, up from the floor by the width of a pine board plus ½ inch. For example, if the pine boards are 8 inches wide, the horizontal line should be 8-1/2 inches up from the floor.
3

Measure the line you just marked, from end to end. Cut a piece of pine board at that length, minus ½ inch.
4

Set the board against the wall, with the tongue edge facing up, right under the horizontal line. There will be a ½ inch space below the board, and a ¼ inch space in the corners at either end.
5

Nail the board in place with your trim nailer, shooting the nails in along the top and bottom at each place where the board crosses a stud.
6

Cut the next board to the width of the wall, minus ½ inch. Set it on top of the first board, connecting them via their tongue-and-groove fittings. Secure the board by shooting nails at a downward angle through the upper edge at each place it crosses a stud.
7

Repeat the process for each plank, building up the wall. Cut the final piece (at the top) along its length with a table saw, so it fits next to the ceiling with a ½ inch space. Repeat for each wall.
8

Install trim along the floor, ceiling and in the vertical corners to cover the extra spaces you left there.
