The process of flooring installation is a lot easier than decking or siding installations.
All you need is patience because you will be doing a lot of measuring of the floor and the wooden boards. First, you need to gather the right tools in order to do this job properly. You will need a circular saw, hammer, tape measure, nail gun, pencil, carpenter square, utility knife, pry bar, fan, vacuum, eye goggles, wedge and block of wood. It may seem like a lot, but these are very simple tools that don’t require you to be a master carpenter to use. Next you need to figure out which room that you want the new flooring installed in. You probably already have an idea about this, but make sure you outline the perimeter just to be safe. Some people like to use chalk for this because it is easier to see while working. However, if you have an allergy to chalk then you can always use a pencil to mark the perimeter as an alternative. Just make sure you draw the line as thick as you can if you use a pencil.
Before getting started with the installation, make sure the existing subfloor is smooth or else you will have shaky flooring after the installation. Also try not to use a subfloor that slopes or else the new flooring will be uneven. If your desired flooring area already has existing wood flooring, then you will need to remove it with a pry bar prior to the new flooring installation. If there are any nails or tacks stuck in the ground, try to get all of them out. The same goes for any carpeting that you may have down as well. Chances are the removal of a carpet will reveal a concrete base that is flat. If for some reason the concrete is uneven, the only thing you can do is to build your flooring with joists, so it can be elevated evenly off the ground. This is what you will want to build the wooden floors on. Now you just need to gather your prefinished Siberian larch wood. It is easier if you get the prefinished wood versus the unfinished because it will be less work for you to do. When you order from larchdeck.com, they will provide wooden boards with the following dimensions; ¾” x 5.4” x6.4.”
Draw an outline of the floor onto the subfloor using either a pencil or chalk. Go to the longest wall in the room first and lay a thin piece of wood about 1/8” thick and wedge it against the bottom. This will space out the flooring, so that it doesn’t scrape against the wall. Begin placing long wooden boards on the floor next to the thin wood piece against the wall. Use an electric nail gun and nail the pieces into the subfloor area. You will want to continue to install the wooden boards on the same row of the floor until you get closer to the end of the room, and come up towards another wall. At this point, your existing wooden boards will probably be too long to fit into the remaining space between the installed boards and the wall. That means you will have to measure the space that is left and cut the wood with a saw to accommodate it. Now the wood should fit perfectly into that space. Once you do this, repeat the process again for the next row and continue on all the way to the other end of the room, or to wherever you want the wooden flooring to stop. Once all of the wooded boards have been placed, you just have to clean up the debris. This involves sweeping, vacuuming and washing. If you bought the prefinished wood, then you don’t have to do anything else.
For those of you that bought unfinished wood, there will be an additional step to the flooring installation. You will need to finish the wood in order to prevent scratches, stains and unevenness in the texture. The first thing you do after you have cleaned up the debris is to sand the floor. Please don’t go old school and use sand paper for this. Buy or rent an electric drum sander and use that to sand off your floor. You should practice on an area of the floor that will be covered with furniture in case you make a mistake. There are different levels to the sander and you have to make sure you don’t sand too deep into the wood. That is why it is recommended that you tilt the machine back and gently lower it onto the floor when you start. Use sandpaper between 20-60 grit. If you think you got the hang of it, start sanding for real in the middle of the floor and work your way to the outer edges. Try to move along the grain of the wood and only overlap during each passing by an inch. After you have reached the edges of the floor, you will need to use a hand sander to manually finish the edges off. Repeat the process again, but this time use more grits in your sandpaper. By the end, you will be using 120 grits on the sandpaper. Once you are satisfied, clean the floor by vacuuming it and then wiping it down with a cloth. Now apply a floor sealer and wipe it into the floor with a mop wiper. This will prepare it for the stain formula, which will give the floor its glossy looking color. Pour the stain formula into a bucket. Rinse the mop in the formula and start sweeping the floor with it. For a better stain, use a hand brush and manually brush the stain formula into the floor. While you are doing this, be sure not to step in any spots that you already stained because it is not dry yet. After you finish staining the floor, you need to give it at least a day to completely dry.
