Calepinage is an important operation when planning a site when it comes to covering a surface, especially a floor. The layout of a tile will allow you to optimize its pose. And this time spent on paper can save you a lot of mistakes on the job site.
But perhaps like Mr. Jourdain, the Bourgeois gentleman so well sketched by Molière and who prose without knowing it, have you already made a calepinage without you suspecting it! Because the word is not very used outside the professionals.
Layout of a tile
What is the layout of a tile?
The layout consists of draw on a plane in what way the tiles will be laid out and by that very fact how much tiles you will need. This operation is therefore performed before buying the tiles. On the other hand, you must have chosen the model to know the dimensions as well as those of the joints and the type of installation. These calculations also allow you to determine the necessary cuts and optimize the installation.
There are different ways to lay a tile:
- Right fitting, the most classic and the easiest.
- Lay diagonally that is to say that the tiles are placed obliquely to the axis of circulation of the room.
- Pose Roman opus which consists of alternating square or rectangular tiles of different sizes.
- Checkerboard pose in which tiles of different colors are alternated.
- Carpet laying to delimit a space like a carpet.
- Pose with a frieze.
The layout is even more important that the pose is not right and the tiles draw patterns.
The layout in practice
It is a small exercise of measurements and calculations to realize with attention:
- Start by taking a small sheet of paper or millimeter. And draw the plan of the room.
- Take the measurements carefully and refer them very carefully to your plan.
- Calculate the total area to be tiled (in m²) by multiplying length by width. If the room is not a perfect quadrilateral and has recesses, encrypt the surface of each and add it all up.
- Calculate the area of a tile (in m²) by multiplying length by width.
- Determine the number of tiles needed by dividing the total area to be tiled by the area of a tile. For safety, add 10% to the figure obtained.
Now you have to determine where in the room you will start laying:
- The pose from an angle is possible if the place has angles and straight walls. You can start from one of these angles by choosing the one that is farthest from the main door.
- Centered laying is recommended if the angles and walls are not straight (this is often the case!) or if the tiles have to make a drawing (laying carpet or laying with a frieze). You start at the center of the room.
Determine this center by tracing the medians, that is, the two perpendicular lines that intersect in the middle of the room.
From this center, draw two perpendicular axes, one of which must be parallel to one of the walls of the room. It is along these lines that you will begin the pose.
Once you determine these items on the paper, place them directly on the floor. And finish the theoretical work drawing the place of the different tiles without forgetting the necessary millimeters between the tiles for the joint.
The white pose, an important step
The white pose consists in laying the tiles in their respective places but without sticking them. Plastic braces will allow you to represent the position of the joint. This is an essential preparatory step if you have not opted for a simple straight laying, if you ask tiles of different colors or if the tiles must represent a pattern.
For a simple installation, simply put two perpendicular rows of tiles. If the result is satisfactory, start the job.
For a more complicated pose, while referring to your diagram, do not hesitate to number the tiles to find the place of each without risk of error.
The blank pose will allow you to see what will concretely give your project and possibly to refine or modify it.
To note: If you do not know what are paper and pencils, you can find on the Internet online software for calepinage. Once you have entered the appropriate measures, the software will issue you the number of tiles to buy, the cuts to make. Some are free and others more professional and complex are paying. To find them look for layout or calpinage + software.
