How to Install a Floating Floor : Step-by-Step Instructions

Before you choose your floating floor, you will have to consider several aspects, such as the quantity of light in the room, the intended use, the number of occupants, etc. Note that a floating floor can be installed throughout the house, except in bathrooms.

Engineered wood (without glue and nails) is often referred to as “floating floor”. As the name implies, this type of floor is neither glued nor nailed to the ground. To install it, you simply have to slot the floorboards one into the other. Since it isn’t permanently fastened to the floor, a floating floor is an environmentally friendly option.

However, the fact that the floorboards aren’t secured to the floor does not mean that they will move around. Once it has been installed, the floating floor is very solid. Nevertheless, if you eventually need to remove the floor, it will be easy to do so. You can even use the floorboards in another room.

Laying the groundwork

Installing a floating floor requires patience and the right amount of preparation. It is important to note that the room’s humidity level will affect the floating floor installation process. If the humidity level is too high, the wood may start to expand, which could create bulging. On the other hand, if the humidity level is too low, the volume of the wood might decrease.

Before you start installing the floor, make sure you measure the humidity level. The surface of the ground should exceed the 15 degrees Celsius mark, the air temperature should be at least 18 degrees Celsius and the humidity level in the room should be somewhere between 50 and 75%. It is also recommended that you remove the wood from its packaging and let it rest in the room for about 72h.

Note that when you install your floating floor, the board should be perpendicular to the windows to conceal the joints, and also perpendicular to the door’s threshold, to ensure a proper transition between the rooms. You should also make sure that the surface on which you are about to install the floating floor is clean, to avoid creating bumps.

The sublayer 

The first step of the process is the sublayer. This element is very important, as it serves to improve the soundproofing of the floor. This sublayer also helps increase the lifespan of your floating floor. There are two types of floating floor sublayers: one which has to be unfolded and another that is sold in the form of a roll. Before you go on to the following step, make sure that the sublayer has been installed throughout the room and that there are no gaps between pieces. Everything should be set in place using metallic tape.

Installing the floating floorboards

Next, you can start installing the floating floor. Since there are many different types of products, it is recommended that you look at the instruction manual that has been provided with the floorboards so you can gain a better understanding of the proper installation technique. One thing is certain: in all cases, a floating floor is easy to install because the basic idea is that you have to interlock the floorboards one into another.

Depending on the techniques, this step is done by installing the boards following a rotating movement, letting the boards fit together or pressing them against each other. For the first corners, it is essential to put separators between the wall and the floating floorboards and this, every 50cm / 19.7 inches. For the rest, it is enough to nest the boards in one another.

The door situation

Whether you decided to install a floating floor under the door at the beginning or at the end of the installation process, the method remains the same. The easiest way to do this is to place a floorboard next to the door to know the exact measurement. Next, saw off the bottom part of the door frame, to install a floorboard in its place. For the rest of the floor, take the measurements accordingly so the boards fit properly within the room.

The pipe situation

Pipes are another one of the potential obstacles you might run into. By chance, there is an easy solution. Simply measure the size of the obstacle and cut the wood of your floating floor accordingly.  The rest of the process will be the same as what has been described previously, which is to install the floorboards in a normal manner.

Once the floor has been installed, wash the surface with certain specific cleaning products. After that, you’re all done! You are now free to enjoy your brand new floor. Just make sure to keep it clean and to take care of it regularly.
