How to install carpet tiles over concrete

Carpet tiles are a favourite form of floor covering for many homeowners. Because individual tiles can be replaced when stains or other damage occurs, tiles are often considered a great option for high traffic areas. While the general process for installing carpet tiles is the same for any type of floor, there are a few extra steps to keep in mind when placing the tiles on a concrete surface, such as an outdoor patio or a basement floor.

Measure the dimensions of the floor that is to be covered. By determining the length and the width of the space, it is possible to accomplish two things. First, you can calculate the square footage of the space and thus know how many tiles you will need for the job. Second, you can use the measurements to determine the centre point of the space, which will be helpful later.

Prepare the floor. This will mean removing all floor coverings from the floor, including old tiles. What you want to work with is a clean palate. In order to achieve this, remove the old tiles, making sure there is no residue of adhesives left behind. Clean the floor thoroughly and allow to air dry overnight.

Get the tiles ready for installation. If the tiles are the peel and stick kind, the preparation time is easily cut in half. You will only need to place the tiles within easy reach, and peel off the protective backing just before placing each tile. In the event that the tiles require the addition of an adhesive, prepare the adhesive according to product instructions and place it in close proximity to the tiles.

Lay the centre tile. Using the measurements taken earlier, find the centre point in the space and prepare the tile for placing. For peel and stick tiles, simply remove the backing and press the centre tile into place. For other tiles, apply an even coat of adhesive with a small brush and lay the tile into place. Press firmly to allow the bonding action to begin.

Mark your grid. With the centre tile as the starting point, use a tape measure to establish rows running the length and width of the area to be covered. An easy way to keep the grid in balance is to complete a row of tiles beginning with going from each side of the centre tile to the rim of the area that you wish to carpet. This creates a cross effect on the floor, but also provides you with an easy pattern to follow.

Lay the remaining tiles. Always begin with the inner section of the space and work outward. This makes it possible to do any trimming necessary at points near the floor moulding, rather than creating an odd shaped tile in the middle of the carpet design.


Be sure to press lightly on each tile after placing the carpet tile in place. This will help to secure the tile in place. If any adhesive runs out from underneath the tile, gently wipe away with a cloth.


This process assumes that the concrete floor is level and sealed. For rough concrete floors, it will be necessary to sand and seal the surface of the floor before carpet tiles can be properly installed. Failure to do so will result in tiles that do not adhere to the floor surface, and begin to buckle over time.
