DIY Tips for Installing Mosaic Tile and How to Avoid the Most Common Tile Mistakes

A huge, personal satisfaction is having control over the appearance of your own home. One of such things is to tile your own house. In reality, installing tiles may be a really relaxing activity (almost like meditation), especially since doing it yourself could help you save money. So this article is for you if you want to spend hours on your hands and knees planning your future picture-perfect floor tile. We'll walk you through the essential procedures while attempting to make you aware of the most frequent errors.

Recognize Your Tools
Take a step back and consider what equipment you actually need before heading out to the store to get them. If you don't do your homework, you can end up purchasing the incorrect kind of instruments for the job. The majority of the tools are reasonably priced and are available at your neighborhood Lowe's or Home Depot, which is good news. Several trowels, mixing buckets, a tile leveling system, cleaning sponges, tile spacers, rubber mullets, and tile nippers or the appropriate tile cutters for your material are all things you will undoubtedly need.

Act like a visionary while thinking like a designer.
It's always a good idea to have a rough draft ready before beginning a design project. The process of tiling will be made much simpler if you have a visual depiction of the finished pattern.

Although you can always visualize the pattern in your brain, it is far more beneficial to have a drawing of the design. Additionally, you can use some interesting, free applications like Tile Calculator to determine the precise quantity of tile required for the project and to visualize the tile arrangement.


There is more possibility for error without a final design. One tile kind might not complement or suit with another that is in contrast, to start. The majority of tile patterns often follow their own unique repeated pattern. You can wind up dissatisfied with the outcome if you choose the incorrect combination just because you liked how those two things appeared independently. Therefore, if you have a design in place, the outcome will always be what you expected.

How to Determine Your MosaicTile Needs
For some of us, figuring out how much tile you need to tile your kitchen backsplash may seem too complicated, but it's not as difficult as it first appears. Simple math and accurate measurements are all that are required. To calculate the precise quantity of tile you need for the job, you can always turn to a range of free interesting apps or websites like Tile Calculator or Or visit

When calculating the necessary number of tiles, don't forget to include a 10% waste factor. Just multiply the room's square footage by 1.1, then round up.

Expect some waste if your room is irregularly shaped (such as circular or triangular), as you will need to cut the tiles to fit.

Exactly why are mockup layouts so crucial?
In a perfect scenario, the owner, designer, or general contractor would always approve the tile arrangement before it is installed by the tile contractor. You can save a ton of time, money, and nerve cells using this straightforward method.


Your ultimate bathroom floor design vision may differ significantly from the installation's actual results. Laying out your tile before installing it is a wonderful idea because of this. In this manner, you can check to see if the tile has any shade fluctuation. Natural stone tiles frequently have shade variations, although porcelain or glass tiles can also vary. The mockup layout, in addition to checking color variations, can aid in choosing the general direction of a design. Prior to deciding on the ultimate arrangement, you can experiment with the patterns and forms of your tile.

How Do You Prepare to Install Tile?
To clean, level, and prepare the surface that will be tiled. Clean the surface with water to remove any debris after using a vacuum to remove all dust.

To prevent common home risks, make sure the surface is smooth and without any sharp or uneven edges. To ensure that the glue and the surface itself properly bind, make sure to clean the tile's back.

Remove any prior coating from the surface by sanding it down. It must be as straightforward as possible. Remove the trimmings if there is carpeting on the floor.

Avoid being greedy when thin-set
Although there are various tile adhesives for various tile types, organic mastic or mortar and thin-set adhesive are the two most used kinds. Before use, thin-set adhesives must be mixed with liquid because they are powdered. On the other hand, ready-to-use organic mastics are formed of latex or petroleum. Despite the fact that organic mastics are frequently quite simple to apply, thin-set adhesives really offer a stronger bond and weight bearing capacity.


Your tiles may lift with little to no force or even slowly come off over time if the adhesive is only spot-applied to the corners of the tiles. For instance, back-buttering is frequently necessary for large format tiles and natural stone tiles (according to the TCNA, tiles greater than 15 inches on any side are considered large-format). fancy phrase, yes? Using the flat side of the trowel, back-buttering is the process of spreading a small layer of thin-set glue to the tile surface's back.

Additionally, keep in mind that certain surfaces may call for various adhesives. For instance, a waterproof glue is required to tile a swimming pool. Use heat resistant adhesives for the backsplash behind the stove or fireplace. For example, fireplaces require a thin-set that can withstand temperatures of at least 400° F.


Prior to selecting the proper grout, adhesive, or tile sealer, you should always take the location of the heat source into account. The best setting materials for installing tiles close to a heat source are those that contain calcium aluminate cement.

Expansion and contraction in Tile Science
When it gets warmer, things enlarge (also known as expand), and when it gets colder, things shrink (also known as contract). obvious: physics Tile reacts to movement fairly quickly. Your tile installation could be impacted by a wide range of factors, including dampness, freezing, structural movements, direct sunshine, and more. The tiles can only travel up as they collide and press against one another. Expansion or movement joints are crucial throughout the installation process for this reason.

In order to reduce the strain caused by movement, a movement joint should either be left open or have a flexible substance inserted between the tiles. In this manner, when expansion or displacement takes place, the two surfaces won't collide.


There is a 99% likelihood that the project will fail if expansion joints are not installed. On the floor or wall, make sure to leave at least 12 inch between the final line of tiles and the following surface or material to allow for expansion. Use smaller-sized tiles if you don't want to worry too much about the expansion. Smaller movements are made with little tiles.

According to American industry requirements, movement joints are required in every tile installation. Why? because they stop the grout or tiles from breaking. The tile can move and avoid damage with the help of strategically positioned movement joints. The movement joints frequently act as moisture-resistors in moist locations because they add an additional layer of defense.

For movement or expansion joints, you can simply leave a gap at the room's edge (no less than 1/4 inch) in smaller spaces. The movement joints will be obvious for larger surfaces.

Remain Calm and Grout
You may believe that selecting the tiles for your bathroom is the most crucial choice, but selecting the proper grout is equally significant. Grout can play a significant aesthetic role in addition to acting as a bonding agent.


Sanded and unsanded grout are the two most popular varieties. Sanded grout is extremely resilient and less likely to shrink. Also keep in mind that delicate tile that needs sensitive handling may be damaged by sanding grout. For instance, when using metal and Mother of Pearl tiles, we advise against using sanded grout.

On vertical surfaces, such shower walls, unsanded grout is frequently utilized. Because it is so sticky, unsanded grout gives wall-mounted tiles a superior grip.

Because cementitious grouts are porous, stains can be readily absorbed. Use epoxy grout if you want to prevent stains from appearing in your grout joints. Make careful to correctly mix your grout; if you use too much water, your grout may turn up unevenly colored. Use epoxy grout since it won't darken or alter color over time if you want to ensure that the grout color is consistent over the entire surface.

It's also important to be aware that porous tile surfaces like travertine can become stained by epoxy grout. Prior to grouting, this sort of tile needs to be sealed.

Do I Need to Seal My Tiles?
In many installation jobs, sealing comes last but is certainly not least. You can make sure that your flooring, backsplash, or grout will look great and be safe for a long time by sealing them. Grout and tile that have been sealed are significantly simpler to keep clean of dirt and spills. Travertine, marble, slate, or granite natural stone tile should definitely be sealed. Being porous, natural stone is able to swiftly absorb spills, bacteria, food particles, and grime. Remember that because most ceramic or porcelain tiles are nonporous, their surfaces don't require sealing. The grout between nonporous tiles may still need to be sealed, though. In other words, sealing your grout can reduce the amount of time you spend washing! Moisture, bacteria, and mildew can all grow on grout and cause ugly discolouration or stains.
