Important Considerations When Choosing an Adhesive
Choosing the right adhesive is essential to ensure correct ceramic placement. There are different factors to take into account when selecting the right adhesive, such as the type of tile, the type of support and its location.
Tile type
The type of tile we are going to install will determine the type of adhesive we should use. There are different types of tiles, such as ceramic, porcelain, terracotta or natural stone. Each type of tile requires a specific type of adhesive that adapts to its characteristics. For example, porcelain tiles generally require a more flexible cement adhesive due to their low water absorption capacity. It is important to do your research and consult with the tile manufacturer before choosing the right adhesive.
Support type
The type of support on which the ceramic is to be placed is also a crucial factor to take into account when selecting an adhesive. Different types of supports, such as concrete, plaster or wood, require different types of adhesives and preparations. For example, if it is a wooden support, it is necessary to use a specific adhesive that is compatible with this type of surface and that offers greater adhesion and flexibility. It is important to know the characteristics of the support before choosing the appropriate adhesive.
Location
The location of the ceramic also plays an important role in the choice of adhesive. For example, if ceramic is to be installed in a wet area, such as a bathroom or kitchen, it is important to select an adhesive that is moisture resistant and offers high water resistance. On the other hand, if the ceramic is going to be installed in an area with high sun exposure, such as a terrace, it is important to select an adhesive that is resistant to temperature changes and UV rays. It is essential to take into account the location to ensure adequate durability of the installation.
Preparation of cement glue mixture
Proper preparation of the cement-glue mixture is essential to achieve correct placement of the ceramic. Follow these instructions to prepare a quality cement-based cement mix:
1. Gather the necessary materials
Before you begin, make sure you have all the necessary materials on hand. You will need glue cement, clean water and a clean mixing container.
2. Provide proper amount of cement glue
Consult the manufacturer's instructions for the proper proportion of adhesive cement and water. Pour the necessary amount of glue cement into the container.
3. Add water gradually
Add fresh, clean water gradually to the cement glue, mixing continuously to avoid lumps and ensure the mixture is of proper consistency. Add water slowly to avoid adding too much and getting a runny mixture.
4. Mix thoroughly
Use a trowel or a suitable mixing tool to mix the adhesive cement and water thoroughly until a homogeneous, lump-free mixture is obtained. Be sure to scrape the sides and bottom of the container to ensure all ingredients are incorporated.
5. Let it rest
Let the mixture sit for a few minutes to allow the ingredients to fully mix and for the mixture to reach its proper viscosity. Don't let the mixture sit for too long, as it may begin to harden.
Proper preparation of the adhesive cement mixture is essential to ensure proper adhesion and successful installation of the ceramic. Always follow the manufacturer's instructions and adjust the amount of water as necessary to obtain a mixture of proper consistency.
Instructions for laying ceramic
Once you have prepared the cement-glue mixture, you are ready to begin laying the ceramic. Follow these instructions to ensure proper installation:
1. Prepare properly
Before you begin, make sure the stand is clean, dry, and in good condition. Remove any loose debris, dust or grease from the backing to ensure good adhesion. Also make sure the tiles are clean and free of dust.
2. Apply the adhesive
Use a notched trowel or trowel to apply the adhesive to the backing. Be sure to apply an even layer of adhesive that completely covers the area where the ceramic will be placed.
3. Comb the adhesive
After applying the adhesive, use the notched side of the trowel or trowel to comb the adhesive and create streaks. This will help improve the adhesion between the adhesive and the ceramic. Maintain an angle of about 45 degrees and avoid pressing too hard to avoid clumping.
4. Place the ceramic
Carefully place the ceramic on the adhesive, pressing gently to ensure proper adhesion. Be sure to maintain even spacing between tiles by using spacers. Continue laying the tiles until you have covered the entire desired area.
5. Adjust and level
Once all the tiles are in place, use a level to make sure they are level and adjust as necessary. Gently tap the tiles with a rubber mallet to properly seat them into the adhesive.
6. Wait for the adjustment time
After laying the tiles, wait the manufacturer's recommended setting time before proceeding to the next step, such as grouting or sealing. This time will allow the adhesive to dry and adhere properly to the tiles.
7. Wipe off excess adhesive
Once the adhesive has dried and hardened, remove any excess adhesive with a putty knife or scraper. Be sure not to scratch the tiles during this process.
Types of adhesives and their characteristics
There are different types of adhesives available on the market for laying ceramics. Each type has its own characteristics and properties that make them suitable for different applications. Some of the most common adhesives are:
1. Cementitious
Cementitious adhesives are the most used in ceramic placement. They are mainly composed of cement, aggregates and additives that improve their adhesion and physical properties. They are suitable for most applications and offer good strength and durability. Additionally, they are easy to use and are available in a wide range of options depending on the type of tile and support.
2. In dispersion
Dispersion adhesives are also popular in the ceramic market. They are composed of polymers dispersed in water and offer high flexibility and deformation capacity. They are suitable for laying large format tiles, as well as for surfaces that are subject to movement or vibration. Dispersion adhesives are also resistant to humidity and offer good adhesion on different types of supports.
3. Reactive resins
Reactive resins are high-strength adhesives used in special applications where exceptional adhesion is required. They are composed of synthetic resins that are chemically activated upon contact with a catalyst substance. These adhesives are suitable for laying tiles in extreme conditions, such as swimming pools or exterior facades. They offer exceptional resistance to water, chemicals and adverse weather conditions.
Each type of adhesive has its own advantages and considerations to take into account when selecting it. It is important to read the manufacturer's instructions and consult with an expert to ensure you choose the right adhesive for your specific project.
