Can you change grout color from dark to light?

Quick Answer

Yes, it is possible to change grout color from dark to light. This can be done by using a grout colorant or by removing the old grout and replacing it with new, lighter colored grout.

Changing Grout Color with a Colorant

One of the easiest ways to change grout color from dark to light is by applying a grout colorant. Grout colorants come in pens, bottles, or kits and allow you to simply paint over the existing grout with a new color.

Here is the process for using a grout colorant:

1. Clean the grout lines thoroughly to remove any dirt, grease, or sealing products.
2. Allow the grout to dry completely.
3. Apply painter’s tape along the edges of the tile to protect the surfaces.
4. Apply the grout colorant as directed, usually in thin, even coats.
5. Allow proper drying time between coats.
6. Apply a final sealant over the grout once the final coat has dried.
7. Remove the painter’s tape.

The benefits of using a grout colorant are that it is inexpensive and easy to apply. It allows you to quickly refresh the look of the grout without having to redo it entirely. The grout also does not have to be removed.

Some downsides are that colorants may not last as long as new grout and may need more frequent touch-ups. The color may also not be as uniform or consistent compared to new grout. Make sure to follow package directions closely.

Tips for Using Grout Colorant

– Carefully read and follow the product instructions.

– Test the colorant in an inconspicuous spot first to ensure you like the color.

– Apply thin, even coats and allow proper drying time between coats for best results.

– Be sure to prep the grout properly so the colorant adheres.

– Consider applying a sealant over the colorant for added protection.

– Gently wash the grout lines with water only after application. Harsh cleaners can break down the colorant.

Replacing Grout with New Color

For the most long-lasting color change, you can replace your existing grout with new grout in a lighter color. This provides a permanent color change.

Here is the process for regrouting:

1. Use a grout saw or rotary tool to remove the old grout completely.
2. Thoroughly clean out the grout lines to remove debris.
3. Apply new grout in the desired color with a grout float.
4. Push the grout deeply into the grout lines for proper adhesion.
5. Wipe away excess grout with a damp sponge.
6. Allow the new grout to cure for 72 hours.
7. Seal the grout once fully cured.

The benefit of regrouting is that it provides a permanent color change that will last. It also allows you to fully refresh the look of the tile and correct any cracks or damage to existing grout.

The downside is that it requires more labor and skill. The process can also create a lot of dust and debris. And the tile typically needs to be protected while the grout cures.

Tips for Regrouting

– Match the new grout color and texture to the old as closely as possible for the best results.

– Make sure to apply grout sealer after installation for protection.

– When mixing grout, follow package directions and only mix as much as can be applied within the time limit.

– To reduce staining or discoloration, wipe the tiles down as you go with a damp sponge.

– Allow a full 72 hours for grout to cure properly before cleaning or sealing.

Comparing Grout Colorant vs Regrouting

Grout Colorant	Regrouting
Less expensive	More expensive
Easy, quick application	More labor intensive process
No grout removal required	Existing grout must be removed
Color may fade faster	Permanent color change
Does not fix cracks or damage	Allows for grout repairs
Lower durability	Higher durability
More frequent touch ups needed	Lasts for years
Color less uniform	Consistent, uniform color

As shown in the table, grout colorants provide an easy, low-cost way to refresh grout color, while regrouting is more labor-intensive but offers a permanent solution. Choose grout colorant for a temporary color change or regrouting for long-lasting results.

Step-by-Step Directions to Change Grout Color

Here is a step-by-step summary of the process both for using grout colorant and regrouting to change grout from dark to light:

Grout Colorant

1. Clean the grout – Use a grout brush and grout cleaner to remove all dirt, grease, and sealing products from the grout lines.
2. Dry the grout – Allow the grout lines to dry completely before applying the colorant.
3. Apply painter’s tape – Tape off edges of the tile with painter’s tape to avoid getting colorant on the tile surface.
4. Apply colorant – Apply thin, even coats of the grout colorant using the applicator brush or bottle tip.
5. Allow drying time – Let the colorant dry completely between coats per product instructions.
6. Apply sealant (optional) – Once the final coat has dried, apply a grout sealant for extra protection.
7. Remove tape – Once dry, carefully remove all of the painter’s tape.
8. Clean grout – Use only gentle cleaning products on the refreshed grout lines.

Regrouting

1. Remove old grout – Use a grout saw or rotary tool to completely remove the existing grout down to the bottom.
2. Clean grout lines – Vacuum and wipe out grout lines to remove dust and debris.
3. Apply new grout – Press the new grout into the lines, filling completely and evenly.
4. Wipe tiles – As you go, use a damp sponge to wipe down the tiles and remove excess grout.
5. Allow curing time – Let the new grout cure for 72 hours undisturbed.
6. Seal grout – Once fully cured, apply a sealant to protect the finished grout.
7. Enjoy new color – Your tile has fresh grout and updated color.

FAQ

Does changing grout color require special tools?

Regrouting requires some special tools like a grout saw or rotary tool to remove old grout. Grout colorant can be applied with common painting supplies like a small paint brush or foam applicator.

How long does grout colorant last compared to new grout?

Grout colorant may start to show wear in 1-3 years, while new grout can last 5-10 years or longer before needing refresh. Grout colorant is better for a temporary fix vs permanent solution.

Is it better to use cement-based or epoxy-based grout?

For floor tile, cement-based grout is preferable for easier repairs down the road. Epoxy is harder to remove if needed. For walls or countertops, epoxy is more stain and water resistant.

What mistakes should be avoided when changing grout color?

– Not cleaning grout properly before application
– Applying colorant or new grout over sealants or dirt
– Failing to tape off edges of tiles
– Not allowing proper drying/curing time
– Using harsh cleaners after application

Will my grout look uneven if I only color some tiles?

It is best to recolor the grout on all tiles in a space for the most uniform appearance. Spot treating some tiles can make the old and new grout colors look patchy.

Conclusion

Changing grout color from dark to light is achievable for most DIYers using either grout colorant for a temporary fix or regrouting for permanent color change. With proper prep and technique, you can refresh the look of your tile and give it an updated style. Carefully follow product directions for best results. And consider hiring a professional if attempting a full regrouting job.
