How to Paint Grout

Update tired-looking grout with paint.

Use paint to give grout a fresh, clean look. Grout is used to bond tiles together. It fills in the gaps between each tile and protects the edges of tiles from cracking and chipping. Grout is used on tile flooring, walls and countertops. Grout paint, also known as grout colorant, can be used to change the color of your grout or simply revitalize your existing grout color. Grout paint can last up to 15 years.

Things You'll Need

• Tile and grout cleaner
• Grout paint
• Artist's paintbrush
• Small container
• Bucket
• Water
• Mop/sponge
• Scouring pad

Instructions

1. Clean the tile with a high-quality tile and grout cleaner to remove residue, stains and grout sealer. Rinse with hot water to remove all traces of the cleaner. Fill a bucket with hot water and dip a mop/sponge into the water and apply to the area. Allow to dry for at least four hours.

2. Pour the grout paint into a small container. Alternately, grout paint markers are available and are used like a pen to apply grout paint.

3. Insert a 1/4-inch artist's paintbrush into the paint and apply a thin, even coat to the grout in a back-and-forth motion. A stiff artist's paintbrush with a square tip works best. Allow to dry for approximately 30 to 45 minutes.

4. Apply a second coat of grout paint for durability. Allow to dry.

5. Pour water into a container. Dip a scouring pad into the water and squeeze out the excess water. Scrub the tile with a damp scouring pad in a circular motion to remove paint from the tiles. Allow to dry for 24 hours.

Tips & Warnings

• Run your fingers through the bristles of the artist's brush to remove loose hairs before use.

• Cushion your knees when working on the floor.

• Use a foam brush as an alternative to an artist's paintbrush.

• Do not use grout paint on unglazed tiles. These will absorb grout paint and permanently damage your tile.

• Use grout paint in a well-ventilated area.

• Wear protective clothing and gloves.
