The thickness of the adhesive is one of the most important factors to consider when installing porcelain tile on the floor in order to achieve a long-lasting and visually appealing finish. If you do this correctly, you can avoid problems like loose tiles, uneven surfaces, and even gradual cracking. Both professional installers and do-it-yourself enthusiasts need to know how to calculate and apply the proper thickness.
The type and size of the tiles, the substrate’s composition, and the particular adhesive being used are some of the factors that affect the ideal adhesive layer thickness. The best outcomes necessitate careful consideration of each of these factors. For example, in order to sustain their weight and keep a level surface, larger tiles typically require a thicker layer of adhesive.
Furthermore, the state of the floor substrate is very important. Whereas an uneven or flexible substrate might require a thicker layer to compensate for irregularities, a perfectly flat and stable surface might require less adhesive. Because different adhesives have different qualities and performance characteristics, it’s also crucial to select an adhesive that is appropriate for the substrate as well as the tiles.
You can make sure that your porcelain tile floor not only looks fantastic but also endures over time by paying close attention to these little details. In the sections that follow, we’ll go over the particular factors to take into account when determining the adhesive thickness and offer helpful advice for a flawless installation.

Factors affecting the thickness
A thinner layer of adhesive material is needed the smaller the tile. Since the floor cladding is not applicable to standard work, there is no specific standard. The adhesive material’s thickness can range from a few millimeters to one centimeter or more.
Reference: The kind of cladding is considered. A smaller amount of glue is needed for porcelain tiles.
It matters what kind and caliber of floor surface there is. A completely different amount of adhesive substance is needed for gypsum and concrete. To ensure that there are no rocks, the thickness of the glue should be determined by accounting for the height of the floors in other rooms.
Substances that are added will determine how much of the mixture is used. For instance, a thicker layer of cement is applied. It doesn’t take as much epoxy composition.
Features of cladding
When laying tiles, it’s crucial to take into account the dimensions of the tile in order to determine the thickness of the adhesive:
- Small -format (10×10 cm) requires a thickness of not more than 2 mm, for completely small squares (up to 7 cm) a layer up to 1.3 mm is suitable.
- With medium -sized and large squares, you need to apply a layer of larger thickness. With a size of 20×30 cm, about 3 mm glue should be applied. When the size of the cladding exceeds 30×50, it is required up to 4 mm.
- Facing with dimensions of 20×25 cm, which is more often used for the bathroom, is glued with a layer of about 3 mm.
The thickness of the adhesive material is also influenced by the type of cladding. Water absorption is impacted by the tile’s high porosity. This means that additional glue is needed. Since cementitious tiles essentially don’t retain moisture, less of the mixture will be needed.
Another factor considered is the porcelain tile’s thickness. More glue is needed for heavier tiles. For light cladding, the thickness is negligible.
Surface type and its value
According to the information on the package, each glue is meant for specific grounds. Additionally, you can see the necessary layer and an estimated cost there.
Surface type and necessary adhesive mixture thickness:
- For drywall, a layer of not more than 5 mm.
- Concrete requires a larger layer up to 1 cm.
- For porcelain tile you need about 2-4 mm.
Citation! It also matters how the floor is. A thick layer of the composition is needed to fill in any imperfections or irregularities with voids.
The product is barely consumed when there are no obvious defects or cracks. When working with uneven surfaces, a specific leveling composition should be selected. Certain products have a layer that is up to 1.5 cm thick. Working with inexperienced masters with them is preferable.
Because of shrinkage, working with aligning compositions can be challenging. Plastering is a better method of defect closure when the defect is larger than 3 cm.
Citation! It is necessary to use a different thickness for wall and floor cladding. The layer is larger in the first instance.
Humidity of the coating
The amount of moisture absorbed directly affects the tile glue level. When the indicator is high, a larger layer is required. Regarding the glue itself, it should not be dry when applying it; otherwise, the clutch will either not work at all or work very weakly.
Citation! Using the primer will help you use less glue.
What is glue consist of
Various combinations call for varying application thicknesses:
- Cement. Powder from sand, cement and plasticizers. Such a solution can be prepared with your own hand. Work with it is easy. The thickness should be about 3-5 mm.
- Two -component. Adhesive mixtures including resin and hardener. After kneading, a viscous composition is obtained, which provides reliable adhesion at minor costs. You can make a small layer up to 3 mm.
- Dispersive. One -component of resin. May contain additional components in the form of polymers. Thickness – up to 2 mm.
It is essential to precisely measure the glue’s thickness when installing porcelain tiles on the floor. The important variables to take into account when determining the glue thickness for installing porcelain tiles are examined in this article. We explore how these factors affect the thickness of the glue layer, from knowing the kind of subfloor to the dimensions and weight of the tiles. We also go over the significance of adhesive coverage and the possible drawbacks of using excessive or insufficient glue. By the time it’s all over, readers will know exactly what to watch out for in order to guarantee a successful and durable tile installation.
Choosing a gear spatula
Using a specialized toothed spatula, also known as a clove-tipped spatula, you can evenly distribute the glue and minimize its consumption. It is chosen in accordance with the cladding’s dimensions. The cloves get smaller the smaller the stove gets.
A spatula with cloves up to 4 mm works well for small square tiles. Teeth should be 6 mm in size in order to work with medium-sized tiles (20 x 20 cm). The ideal size for mosaic will be 2-3 mm.
Citation! It is advised to purchase multiple spatulas with varying tooth sizes if the base is uneven.
Minimum and maximum
When laying the floor, there are minimal and maximum limitations on the thickness of the glue beneath the tiles. It is best to avoid crossing them so that the porcelain tile is fixed both qualitatively and long-term.
The lowest value is determined separately based on the tile dimensions. Generally speaking, a layer’s thickness for small squares should start at 2 mm. The minimum value rises to 4 mm for heavy tiles.
22 mm is the maximum thickness for porcelain tile lining. Even greater sizes will cause the adhesion to deteriorate, and these are unreasonable material costs.
The desire to level the floor and conceal the flaws is typically correlated with an increase in layer thickness. Though there are a few minor issues, this is the right choice. Use specific alignment techniques when there are noticeable irregularities.
Calculation of the amount of material
You must have all the information regarding the material, the jet, and the working area in order to calculate the necessary amount of the mixture. There are several steps involved in the calculation.
How to calculate the appropriate amount of money:
- Determine the dimensions of the tile, based on which, calculate the desired thickness.
- Look at the package, what is the consumption of the mixture per meter with a layer of 1 mm.
- Change these values, receiving the required amount of glue.
- Calculate the area for cladding.
- Multiple the first value by meters.
- Multiply the result by 1.1 for stock.
The thickness of the glue used when installing porcelain tile may not seem like much at first, but it can have a big impact over time.
The kind of subfloor you’re working with is one important factor to take into account. The stability and state of the subfloor, whether it be made of plywood, concrete, or another material, will determine how much glue you need and how long the tile installation will last in general.
The dimensions and weight of the porcelain tiles themselves should also be considered. For larger, heavier tiles to be properly supported and to avoid chipping or shifting over time, a thicker layer of glue will be needed.
It’s also crucial to adhere to the glue manufacturer’s instructions for the particular kind of glue you’re using. For best results, make sure you carefully read the instructions and use the recommended amount of adhesive, as different adhesives have different properties and needs.
In the end, taking the time to determine the proper glue thickness for installing porcelain tiles can help guarantee a strong, durable floor that will continue to look fantastic for many years.
