After the entire floor is covered with Rosin paper, start your installation in a corner of the room. Using a speed square, measure your first 90 degree piece (Image 1). Using a miter saw, cut two 45 degree angles, one on each side of the wood plank (Image 2). This will give you your 90 degree piece.
When the first piece is secure, take your measurements to get your plank length (Image 1). Cut another set of 45 degree angles: one on each side of the plank using a 12” miter saw. Once each plank is cut, fit the tongue side of the previous plank into the grooved side of the new plank. Use a rubber mallet and tapping block to tap planks into place (Image 2).
When the planks are locked in, take a flooring stapler and place tip onto the tongue of the plank. Staple the plank onto floor every 6 inches, keeping the tip of the stapler on the tongue of the plank.
Repeat steps 4 and 5 for all remaining planks of flooring, making sure you are working away from the original corner.
