Installation guide for Interior Terrazzo Tile

Preparing proper surface and selecting adhesive, mortar (for tiles, and joint grout) suitable for interior terrazzo tile.

1. TILING

Step 1: Preparing the ground before installation

 - In case of direct installation on concrete: Using laser or water scale to check the ground, if it is not flat, it must be chiseled, patched, repaired to make flat ground.

 - In case of paving on the sandy ground: Flatten the sandy ground, then pour the concrete layer to make the ground flat. Next, use the cement mortar to roll the foundation, flatten the thickness of 5-7cm, and then proceed to paving bricks after 24 hours

Note: The surface must be clean, dry before installation.

Step 2: Arrange and position the tiles

   Take a mark, use a wire to determine the correct installing position according to the drawing.

Step 3: Preparing the adhesive

Use a suitable fast setting and hydrated tile adhesive. Use a large trowel to spread the adhesive.

 - Follow the manufacturer's instructions to prepare the tile adhesive,.

 - Spread the 0.5-1cm thickness adhesive directly onto the substrate then use a serrated trowel to flatten.

Step 4: Spread the adhesive on the back of tile

  Spread the adhesive on the back of tile and place the tile in the position where the adhesive was previously positioned.

Step 5: Tiling

  Put tile in the area that were positioned before, use rubber hammer to close down at the determined height. Keep a gap of at least 2mm between the tiles.
 

2. PREPARATION BEFORE GROUTING

In the process of installing, it is necessary to be very careful to keep the surface of the tiles clean, not to let the glue stick on the surface for long time. After tiling and adhesives have dried, clean the surface by wiping dirt with a towel, rinse with neutral detergent diluted with water, rinse thoroughly with clean water and dry the surface.

Note:

- Do not walk, or leave heavy objects on the floor for the first 24 hours after installation

- Grouting will be applied after 2-3 days from tile installation date.
 

3. GROUNTING FOR INTERIOR TERRAZZO TILE

It is recommended to use a flexible cementitious scrubber mixture suitable for the application of Terrazzo tiles. Do not use ordinary cementitious mortar to scrub, use reputable abrasives on the market.

Before grouting, use a vacuum cleaner, clean the dirt from the tile slot and clean it on the tile floor.

Step 1: Cleaning the tile surface to remove adhesive and dirt

 - Always make sure the tile surfaces are clean (using a patch or primer to protect the tiles) before grouting them to prevent dirt, or adhesives remain on tile surface.

Note: tile surface must be clean and dry

Step 2: Grouting

Filling the gaps between tiles by grout, ensuring seamless and full joints

Step 3: Clean the excess grout

Using cloth to remove excess grout immediately. Do not use chemical cleaners.

Step 4: Clean tile surface

Using neutral detergent to clean tile surface right after grouting. Do not use harsh detergents or bleach as they can damage the tiles. Stains or spots that are hard to remove can be removed slowly with a scouring pad or fine sandpaper.
 

4. APPLYING SEALER

After finishing tiling and grouting, it is necessary to clean the entire floor again using a vacuum cleaner, using clean water or a neutral detergent diluted with water to wipe the entire floor and dry the floor. After cleaning the surface of the tile, apply protective sealer on the tile.
