There are no restrictions for interior walls, but some suggest that maximum weight should not exceed 15 lbs. per square foot. Larger and heavier tiles will require anchoring with mechanical fasteners.
Generally, standard drywall can bear the load of most tiles. However, when dealing with heavier or larger tiles, it's imperative to consult professionals to ensure the wall's structural integrity remains intact.
It is possible to tile over drywall where it is not subject to extreme humidity and is secure. It is not recommended to lay tiles over walls and areas subject to moisture, such as in showers. The water in these areas could eventually seep into the tile, causing damage to the tile, mold, or infestations.
While drywall alone can hold about 1.6 pounds to 2 pounds per square foot, mounting an object to the stud with the proper hardware allows the drywall to support up to 100 pounds.
If the weight of the floor tiles combined with grout and adhesive exceeds the maximum weight per square feet, we do not recommend using it for walls. Can you use floor tiles on walls? Yes, but considering its weight. Just as a reference, most commercial tiles are five to seven pounds per square foot.
Question: What is the maximum tile size and weight that can be installed on walls? Answer: For direct bond installation on commercial projects, International Building Code limits tile on exterior walls to less than 24" on one side, less than 3 square feet total area and less than 9 lbs. per square foot.

Whether you have a brick or uneven stone façade, or mounting a TV above a fireplace, mounting a TV can be tricky, but even more so when mounting a TV without studs. Even though drywall can support a TV up to 100 lbs., it's still brittle and the mount can require additional support.
One square meter of double plasterboard can support 25 kg, and triple wallboard can support 35 kg. The studs reset the weight that the wall can cope with. For example, one square meter to the left of a stud can support 15 kg, and one square meter to the right of the stud can support another 15 kg.
However, while plywood is now not recommended as a background for direct wall tiling, it can still be used as a structural board when overlaid with a suitable tile backing board, particularly where installation of mechanical fixings is required e.g. for mesh backed natural stone where it is not possible to remove 75% ...
You may tile over existing tile, painted or unpainted drywall, plaster and textured walls. But tiling over tile can add quite a bit of thickness, so make sure your wall can handle the weight. You should not tile over wallpaper, glossy surfaces, lead paint or plywood.
Blueboard on the other hand is a type of wallboard that is more absorbent than drywall and specifically designed to bond with a veneer plaster. In New England, drywall is most often used in commercial settings.
Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.
Walls that run perpendicular to the joists are load-bearing walls. Walls that are parallel to the joists rarely are, but sometimes a bearing wall will be aligned directly under a single joist. If purlin bracing is attached to the top of a wall or is supported by a wall, it's a load-bearing wall.
As a rule of thumb, pictures that weigh less than 5 pounds can be hung with hanging strips, adhesive wall hooks or mounting tape.
A French cleat is a hanging system consisting of two beveled pieces of wood that interlock to distribute weight evenly across a wall. This method is ideal for items that span multiple studs. It's especially useful for items like wall-mounted cabinets or shelves, which require substantial support.
One key difference between the two is that sheetrock is a brand name of drywall made by the United States Gypsum Corporation. Another difference lies in their production process; sheetrock has a slightly denser core than drywall due to the addition of a small amount of wood fiber to the gypsum core.
Drywall anchors can hold anywhere from 10 to 200 pounds, depending on the type and installation. Always choose an anchor rated for more than the weight of the item you are mounting.
Check your walls
Unless it's a really old house, you'll probably have a few different kinds of wall in your home. The most common are brick and stud walls. Most walls can support a TV, but you need to be more careful if you're mounting on a stud wall. Here's what you need to look out for…
The simple answer is yes: you can apply any tile to your wall. However, if the tile isn t fit for purpose, and is too heavy for your wall, then it will fall, either over time or almost immediately.
The maximum weight of tiling which can be supported by a dry, well-adhered plaster background is 20kg/m². This is equivalent to ceramic tiles with a maximum thickness of 8mm plus tile adhesive or natural stone tiles with a maximum thickness of 7mm plus tile adhesive.
While ceramic wall tiles used to be installed directly onto the wall, it's now a common practice to first install a layer of cement board before applying adhesive and laying the tiles.
