How to Fix New Grout That Has Color Variations

Fix color variations in your grout with grout stain.

You can easily fix color variations in your new grout with a grout stain. However, you must allow your new grout to cure for at least 30 days before applying a stain. Once the grout has cured, choose a grout stain color that is at least as dark as the darkest variation in your grout's color. Grout stains will not lighten a darker shade. If you use a shade of stain lighter than your grout, you will still have color variations after all of that hard work.

Instructions

1. Clean the tiled floor or wall thoroughly. Allow it to dry completely.

2. Apply painter's tape to the rows of tile directly adjacent to the line of grout that you will be staining. Carefully applied tape will keep you from accidentally staining your tile. If you accidentally apply dye to the tile, wipe it away quickly

3. Brush a thin layer of the grout stain onto the grout with a small, stiff-bristled artist's brush. Follow the manufacturer's instructions for any further directions specific to the type of stain that you are using.

4. Leave the grout stain to cure once you have stained all of the grout. Read the grout stain's label for minimum curing time.

5. Remove the painter's tape.
