Application of procedure for cement paste for wall tile

 

Applying cement paste for wall tiles involves the following steps:

 

Surface Preparation: Ensure that the wall surface is clean, dry, and free from any dust, debris, grease, or loose particles. Remove any old paint, wallpaper, or other coatings that may hinder proper adhesion. Repair any cracks or imperfections in the wall surface and ensure it is structurally sound.

 

Mixing Cement Paste: Cement paste is typically prepared by mixing cement and water to create a smooth and creamy consistency. Use a clean mixing container and follow the manufacturer's instructions for the recommended water-to-cement ratio. It is important to achieve a homogeneous paste without any lumps.

 

Applying Cement Paste: Using a steel trowel or a notched trowel, apply a thin layer of cement paste onto the wall surface. Start in a small area that you can comfortably work with to ensure that the paste remains workable during the application process. Spread the paste evenly and smoothly, covering the entire area where the tiles will be installed.

 

Comb the Cement Paste: After applying the cement paste, use the notched side of the trowel to create ridges or comb marks in the paste. This helps to ensure proper coverage, adhesion, and leveling of the tiles. The size and depth of the ridges will depend on the recommended notch size for the specific tile size and type being used.

 

Tile Installation: Begin installing the tiles onto the cement paste while it is still fresh. Press the tiles firmly into the paste, ensuring that they are properly aligned and seated. Use tile spacers to maintain consistent grout joints. Periodically check the alignment and levelness of the tiles as you progress with the installation.

 

Grouting: Allow the cement paste to dry and cure according to the manufacturer's recommendations before proceeding with grouting. Typically, this requires waiting for the cement paste to harden and set, which can take several hours or even a day. Refer to the cement paste manufacturer's instructions for the recommended curing time.

 

Grout Application: Once the cement paste has fully cured, remove the tile spacers and apply grout between the tiles. Follow the grout manufacturer's instructions for mixing and applying the grout. Use a grout float or a rubber grout trowel to push the grout into the joints, ensuring complete coverage. Remove any excess grout from the tile surface using a damp sponge or cloth.

 

Curing and Cleaning: Allow the grout to cure according to the manufacturer's instructions. Typically, this involves keeping the grout moist and protected from excessive drying. Once the grout has cured, use a grout haze remover or a damp cloth to clean any grout residue or haze from the tile surface.

 

It is important to follow the manufacturer's instructions for the specific cement paste and grout being used and to consider factors such as ambient temperature, humidity, and ventilation during the application process. Proper surface preparation and correct mixing techniques are crucial for achieving a strong and durable bond between the wall tiles and the cement paste.
