When you are working with tongue and groove porch flooring, there are things that can go wrong with it. No matter how well you take care of your flooring, it will still need to be repaired from time to time. As long as you keep up with these repairs, you won’t have very many issues when it comes to actually repairing them. Just make sure that as soon as you see any problems arise, that you waste no time in getting them fixed.

Step 1 – Adjustments

The first thing that you are going to have to do is get the depth of the circular saw blade adjusted. Make sure that the adjustments are made according to how thick your replacement board is. This is something that will usually be around ¾ of an inch. If the proper adjustments are not made, you could end up doing more damage to the brand new board than what is there with the board that needs to be replaced.

Step 2 – Cut Board

Get the blade guard pulled back from the saw blade so that it is completely exposed. You will then need to get the front edge of your saw pulled down over your wood. Make sure that the front edge of your saw is pushed down onto the board. The blade needs to be up over the actual surface and perched. The trigger on the saw should be held in so that it can be engaged. From there, get the blade lowered onto the surface. Move forward on your saw and cut along the board’s edge. The edges of the board should not be cut, so you need to be sure that the guard is placed in an area that will prevent this. Keep the blade within the edges of the guard to avoid making a mistake.

Step 3 – Cut Lines

You can start to make additional cuts as you need them using the same method as you did above.  As you work, be sure that you maintain the same measurements for each additional cut. This will ensure you have an even surface when you begin to lay the porch flooring. Once you have them loosened, you can use a chisel and hammer to get the sides of your board knocked inwards and towards the middle of the board. Make sure that they go in the direction in which your area is carved out. This must be done before you start the installation process. 

Step 4 – Remove Damaged Board

In order to get your damaged board removed, you are going to need to get the edge of your chisel set up along the edge of the board. Tap inward on the edge and move it towards the middle cut out with a hammer. Get the edges of this board knocked inward on either side with your tongue and groove fittings of each of the adjacent boards.

Step 5 – Lay Replacement Plank

Once you have cut and adjusted the replacement plank, you will run wood glue on the rest of it and press it into place.
