If you have glueless laminate flooring and part of it is damaged, you could potentially replace those boards. This process is simple but it will take a little bit of work on your part. Here are the basics of how to replace damaged boards with glueless laminate flooring.
Step 1 - Prepare the Area
Before you can replace the boards that are damaged, you need to prepare the area. Start out by moving all of the furniture off of the laminate and taking anything else out of the room. Then you need to take the baseboards or quarter round off of the wall. You can use a pry bar for this part of the job. Try not to break the baseboards as you will be replacing them at the end of the job.
Step 2 - Remove the Laminate
Laminate is a product that locks into the pieces around it. This means that you will not be able to remove a board out of the middle of the floor. You will have to work from the side of the room into the damaged area. Start on the side under where you took off the baseboard. Then pull up on the board and unhook it from the adjacent board. By angling it up, the piece should come out of the joint. No matter how carefully you proceed, some damage could occur while trying to separate the boards from the locking tongue-and-groove assembly, so if you plan on re-using the boards, work slowly to reduce the number of spoiled planks. Set the boards aside that are still in good shape as you can reuse them later. Discard the boards that are damaged.
Take some of the new boards and install them in the area where you took up the old laminate. Place a board right up against one of the boards that are still on the floor and join them together at the laminate joint. Then use a rubber mallet to lock the two boards together. For this part of the process, be careful not to tap too hard. Depending on what type of limit you have, the joint can be very fragile and could break when you hit it.
When you have to resort to using power tools for cutting some of the pieces, be sure to first put on a pair of safety glasses, as the particles coming from it are extremely abrasive. In some cases, you may need to cut some of the boards to fit. If this is the case, you can use a table saw or a laminate chop saw for the job. Measure the size of the board that you need and then make the appropriate cut with your saw.
Step 5 - Finishing Up
Once you have all of the laminate installed, you need to finish up the job. You can now put the baseboards back on the wall by nailing them into place. If you have a nail gun with finish nails, this would be the best approach to take. If not, you can use a hammer and nails. You can also now move the furniture back into the room and start using the floor again.
