Using Grout Lines Around Mosaic Tile: Creating a Slip Resistant Bathroom Floor Using Grout Lines Around Mosaic Tile: Creating a Slip Resistant Bathroom Floor

What You'll Need
Mosaic Tiles
Thinset Mortar
Grouting Sponge
Rubber Gloves

You can apply grout lines around mosaic tiles in the bathroom to make the surface slip resistant. Follow the simple steps below to effectively apply grout lines to the tile floor in your bathroom.

Step 1 – Planning

Planning is a very important part of this project. Be sure to come up with a good mosaic design and gather enough cracked mosaic tiles to create the design. Ceramic tiles of any color can be used as tiling materials.

Step 2 – Laying the Mosaic on the Floor

Draw the basic design first on the bathroom floor before laying out the tiles. Mix a good amount of thinset mortar on a bucket or container. Apply the thinset on the underside of each mosaic tile piece and press it firmly on the floor. Remember to leave at least 1/8-inch grout lines in between the tiles for the grout to go into. Do the same for all tiles until the floor is fully tiled. Wait for the mortar to cure before proceeding with the grouting process. The grout will serve as a double adhesive along with the thinset mortar.

Step 3 – Choosing a Grout Color

Use non-sanded grout and choose a good color for application. White, beige or grey are the basic colors, but there are also other colors to choose from. Take note that colored grout may be harder to replicate so make sure to purchase enough grout of the same color to avoid color issues during grouting. If not, just stick to the basic white, beige and grey colors to minimize errors.

Step 4 – Mixing the Grout

Pour the grout in a container and add water little by little. Do make sure to leave some grout powder just in case the mixture becomes too wet. Stir the mixture with a trowel until a mud-like consistency is achieved. If it is too stiff, it may have a tendency to pull out the individual tiles from the floor. If it is too sloppy, it may shrink and create low areas in the grout lines. Do make sure to mix enough grout for the entire floor.

Step 5 – Applying the Grout

Do not use a rubber float for this grouting application. Instead, obtain a grouting sponge. Wear rubber gloves during application. Place a sufficient amount of grout into the sponge and apply it evenly onto the joints on the floor. Move the sponge from side to side while firmly pressing it. Add more grout to fill in every space. Do not leave any low areas in the grouting lines.

Repeat the procedure until every joint is filled with the material. Let it sit for about 30 minutes. Wipe the entire floor with a damp sponge to remove the excess grout on the tile surface. Allow the grout to cure for about 2 to 3 days before applying a sealer.
