How to Lighten the Grout After Paint Has Dried

What Household Items Can Be Used to Lighten the Grout After Drying Paint?

If you’ve ever painted a room, you know that it can be a tedious and time-consuming process. But once the paint has dried, you may find that the grout between the tiles has become darker than you’d like. Fortunately, a few household items can lighten the grout after the paint has dried.

Baking Soda

Baking soda, the most versatile of all household items, can lighten the grout after the paint has dried.

  • Simply mix a few tablespoons of baking soda with a small amount of water to create a paste.
  • Apply the paste to the grout and let it sit for a few minutes before scrubbing it off with a brush.
  • It will remove any excess paint and lighten the grout.

You can also make a cleaning solution by mixing 1 part baking soda with four parts of water. Apply the solution to the grout and let it sit for a few minutes before scrubbing it off.


After the paint has dried, vinegar is another fantastic home ingredient that may be used to lighten the grout.

  • Simply mix equal parts of white vinegar and water in a spray bottle and spray it onto the grout.
  • You can increase and decrease the amount of vinegar depending on the stain type. Allow the solution to stay 10 minutes before scrubbing it with a brush.
  • Then rinse with water.

Remember, if you have Granite, Marble, Limestone, Travertine, and Terracotta tiles, using vinegar can cause tiles discoloration.


One of the safest options to remove dried paint and lighten the grout is bleach. The best thing is it is safe to use on all types of tiles.

  • Mix 1 part bleach with four parts of water and apply it to the grout.
  • Let it sit for 30 seconds.
  • Then start scrubbing with a brush.
  • Leave the solution for another 10 minutes, then rinse with water.

Note: If you recently put any color to the grout, using bleach will remove the color.

Does Grout Darken Over Time?

Grout is used to filling the gaps between tiles and other surfaces. It is a porous material that can absorb dirt, dust, and other particles, which can cause it to darken over time.

This is especially true for light-colored grout, which can become discolored and stained with age.

But if you seal your grout, it can help protect it from dirt and staining and help prevent it from darkening with age. Sealing your grout will also make it easier to clean, as dirt and grime will not be able to penetrate the sealant.

Is it Possible to Change The Color Of the Grout Without Re-Grouting?

Changing the color of the grout without re-grouting is a great way to give your tiled surfaces a fresh new look without the hassle of a full re-grouting job. But can you change the color of your grout without re-grouting?

There are many ways to change the color of the grout without re-grout. You can easily do it yourself with the right materials and tools. Here are some of the most popular methods:

Grout Stain

One way to change the color of your grout is to use a grout stain. It is a specially formulated product that can be applied directly to the grout lines. Grout stains come in various colors, so you’ll find one that suits your taste.

Grout Dye

Another way to change the color of your grout is to use a dye. Dyes are available in both water-based and oil-based formulas. Water-based dyes are easier to work with and clean up but may not be as durable as oil-based dyes. Whichever type you choose, simply apply the dye according to the manufacturer’s instructions.

Grout Colorant

Grout colorant can transform the look of any tiled space. You can instantly add depth and dimension to your tiled area by adding color to the grout lines. You can make a bold statement or create a subtle and timeless look depending on your chosen color.

Grout colorant is a great way to cover discoloration or imperfections in existing grout lines. It is a mixture of pigments and sealers, so you don’t have to seal the grout after applying the colorant.

If you made any mistake while doing a paint job or selected the wrong grout color, following these methods can be a great way to change the color of your grout without re-grouting.

Can I Use the Same Fix for Runny Paint on Grout After Painting?

Yes, you can use the fix for watery paint problems on grout after painting. Simply add a grout sealer to the affected area to prevent further water damage and ensure a smooth and long-lasting finish. This will help to seal the grout and protect it from any future paint issues.

What Happens If You Paint Over Grout?

You may consider painting over the grout if you want to give your tile a fresh look. But is this a good idea? Let’s look at what happens if you paint over grout.

First, you need to know that not all grout is created equal. There are different types of grouts, including cementitious and epoxy-based grouts. And each type of grout responds differently to paint.

Cementitious grout is very porous, so the paint will likely just soak in and never dry properly. This can lead to peeling and chipping down the road. Plus, painting over cementitious grout can void your warranty.

On the other hand, epoxy-based grouts can generally be painted without issue. Use a high-quality epoxy resin paint designed on ceramic tile or glass surfaces. Apply two coats for best results, allowing each coat to dry completely before applying the next one.

Changing The Grout Color in 60 Seconds


If you didn’t notice the paint on the grout until after it had dried, Grout cleaner or a mixture of baking soda and water could help lighten the grout. But when you dislike the darkest shade of recently applied grout, you can use a grout colorant to lighten the grout. So, try these techniques if you’re looking for a simple way to refresh your grout.
