Does Grout Stick to Wood?

Grout Stick to Wood

We know that grout sticks to porcelain, glass, and marble, but does grout stick to wood?

Yes, grout does stick to wood! In fact, it sticks quite well on wooden surfaces. As such, you need to be careful when applying grout to a wooden tile or surface. This is especially true if you’re using sanded grout, as sand may scratch the finish of your wood.

Luckily, there are ways to remove or clean grout on your wooden tile without damaging it. Usually, wiping off any excess with a steel wool pad will do, but this method won’t work if the grout has already hardened.

Let’s take a look at some of the best methods of cleaning grout on wood:

How to Remove Dried Grout on Wood (Without Ruining It)

Grout can be difficult to clean from wooden tiled floors and walls, especially if it has already hardened. Removing it with a metal chisel can greatly damage the surface of the wood, so don’t give in to first instinct and try these alternative methods instead!

Clean With Sugar and Water

For this method, you need about a gallon of hot water, a cup of sugar, a towel, a nylon scouring pad, a wood stick, and, of course, a deep bucket! If the grout stain isn’t too big, you may use half the ingredients.

In the large bucket, mix the hot water and granulated sugar until the mixture is fully dissolved. Then, pour it over the grout that you want to remove.

Be generous with the application as the grout must be fully soaked with the sugar and water mixture. Then, leave it for about an hour or two.

Once the mixture is slightly more malleable, gently scrape the grout using a wooden paint stick. The wooden paint stick should be gentle enough that it won’t scratch the surface of your wood.

If the grout doesn’t budge, don’t force it. Add more sugar water to the stubborn area and focus on another location. Keep the grout completely wet as you work.

When all the large pieces are removed, switch the wooden paint to the nylon scouring pad. Dip the pad into the sugar water and gently remove any remaining grout.

Clean With Water and Wood

This method calls for a bucket of warm water, a towel, a nylon scouring pad, and a piece of hardwood (with a square-cut end).

Similar to the sugar and water method, you’ll first need to soak the grout you want to remove in warm water. This allows the grout to weaken, thus making it easier to take off. Leave it for about an hour or two before you start working.

Take the piece of hardwood and gently scrape off the grout using light to medium pressure until you’ve removed most of the heavy grout deposits. Then, rinse the wood with water and pat it dry with a towel.

Remove any remaining grout residue using a damp nylon scouring pad. Use plenty of water as your scour.

Clean With Epoxy Removal

If both of the above methods fail, it’s likely that you’re dealing with an epoxy-based grout. Epoxy-based grout is water-resistant and is almost impossible to remove when fully cured.

The only way to remove epoxy-based grout is to use an epoxy remover, such as the Attack Epoxy Remover or the Stonetech Epoxy Grout Film Remover. Grout removal instructions are usually listed on the back of the product.

Keep in mind that the epoxy grout remover needs to be carefully applied with a soft-bristled brush to prevent scratching the wooden finish. Leave it to soak on the grout for about 10 to 20 minutes before you attempt to remove it. 

Use a nylon scrubber to dislodge the grout from the wood’s surface using small, circular motions, followed by a grout sponge to remove and wipe off residual grout.

Clean With White Vinegar

This method is often used to remove dried cement on wood, but it works just as well with grout. You’ll need warm water, vinegar, and a nylon scrubber.

First, soak the grout with warm water for a few hours. Then, gently remove the grout using a nylon scrubber. Occasionally clean the area with a wet towel to remove any grout residue.

Once 70 to 80% of the grout is removed, soak a clean cloth with white vinegar and lay it over the remaining grout. Let it sit for several hours. Then, remove the cloth and scrub off the remaining grout with a scrub brush.

The mild acid in vinegar should loosen the grout enough so you can remove it. Clean the area with a water-dampened cloth once all the grout is removed.

How to Remove White Grout Haze On Wooden Tiles

After grouting tiles, a “white haze” is often left behind. Unfortunately, white haze can’t be removed with just water. You need a number of special tools to take it off, including a grout sponge, a grout float, and a grout haze cleaner.

Before you attempt cleaning the white haze, you first need to make sure that the grout is 100% dry, which usually doesn’t take more than 24 to 48 hours. Don’t wait longer than 10 days to clean the white haze, as it’ll be harder to remove as time goes by.

Once the grout is dry, start by removing the haze using your grout sponge and water. Then, grab your grout float and gently slide it over the wet area several times. Repeat this process until most of the grout is removed.

If the haze remains, you might need to use a grout haze cleaner. Manufacturers usually recommend using about three ounces of grout haze cleaner per single gallon of lukewarm water. Repeat the above process with the product until the haze is fully removed.
