How to Dispose of Grout

If you’ve been fixing up your flooring, chances are you have some grout left behind that you don’t know how to get rid of.

Here are some quick and easy measures to dispose of grout, so it doesn’t take up unnecessary storage space around your backyard shed.

Take it to the Local Landfill Site

Many landfill sites across the country have a separate section to store any hardware and repairs tools and materials. These aren’t disposed of or landfilled.

Instead, they are safely stored for people to leave and pick up as per their needs.

By taking your leftover grout at a similar landfill site, you eliminate it while also ensuring you don’t contribute to the ever-growing landfill problem in the country.

Your grout will be used up by the next person working on their flooring or other home repairs.

Similarly, you could also ask around your neighborhood, friends and family if anybody is in need of any grout for repairs.

It is always better that somebody uses up your grout than wasting it away by disposing of it.

Harden it With Water

If there is no possible way for you to hand over the grout to somebody else to use, don’t worry; we will teach you how to get rid of it.

Here are the steps to follow on how to dispose of grout.

Materials You’ll Need

  • Bucket
  • Water
  • Garbage bag

Steps to Follow

Step 1 – If you have any tools with wet grout, dip them repeatedly in a plastic bucket full of water. Wipe the grout off with your fingers and make sure all of the concrete comes off. Rinse any wet grout rags in a similar way. Be sure to avoid the sink at all costs.

Step 2 – Throw out all of the grout water left behind in your bucket, along with any extra grout that you may have. Let it dry up on the soil in your backyard. Then, scoop up this solidified grout, place it in a sturdy container and throw it in your trash.

Step 3 – Be sure to knot your trash bag well to avoid any of the grout pieces falling out.

What Can You Do With Leftover Grout?

Once you are done grouting your tiles, there are several ways in which you can make good use of the leftover grout.

You can mix your grout with paint in a 1:8 ratio and add some beautiful colors to your walls.

This mixture created chalkboard paint, which is a super fun DIY project to do with the kids.

You can also see if any of your old grout needs replacing or even ask if your neighbor needs some to fix up their flooring. Grout is never really ‘useless’.

How Do You Get Dried Grout Out of a Bucket?

Just because there is grout residue on your buckets, it doesn’t mean you will have to throw them out. Here are some steps you can follow to get dried out grout off the buckets easily.

Step 1 – Mix a cup of granulated sugar in a large bucket of hot water. Let it dissolve properly by constantly stirring.

Step 2 – Pour this sugar solution over the dried grout. You can use a sponge to apply it over any vertical surfaces.

Step 3 – Leave the solution to soak up on the dried grout for about two to three hours. This allows the sugar and water mixture to loosen the grout’s bond to the bucket and come off.

Step 4 – Scrape off any of the bigger chunks of grout using a stick or metal scraper. Then, apply more sugar water to the remaining grout so it softens up and you can scrub it off easily.

Step 5 – Be sure to keep wetting the grout with the water mixture as you work, so it doesn’t dry up again.

Step 6 – Once all of the grout is removed, hose down your bucket well and wipe it dry. You can now use it for any other purpose and no longer have to throw it away.

Can You Dump Grout Water Down the Drain?

You should never dump grout water down the drain. This is because the grout content of the water gives it the ability to harden over time.

When the grout hardens in your drains, it will cause a major obstruction or blockage, leading to cracked and burst pipes.

If left untreated, you could even end up with a flooded basement or toilet boiling over.

What to Do With Grout Water?

When you’re cleaning out your tools and equipment after working with grout, you will be left with quite a large volume of muddy water.

Since this grout water can’t be flushed down the drain, it can be not easy to dispose of it.

Water slurries like grout water can block your pipes and cause obstructions in the waterways.

Even if you dilute it with a lot of water, the sand in the mixture will still retain its solid state and accumulate as residue in any low spots in your water piping.

Instead, you should stir up the grout water so it can be easily poured into a disposable basin or an old container with the top cut off.

You can even use a plastic trashcan that has been lined with a sturdy garbage bag. Pour the grout water into your container of choice and let the concrete content harden overnight.

You can then pour off the leftover water in the morning and throw out your container with the hardened grout in the trash.

How Long Does Grout Last in the Bag?

A general rule to remember is that grout expires almost a year after production.

Also, keep in mind that different rules apply to different types of grout. Powdered grout will expire after one year.

But, on the other hand, sealed epoxy grout can be stored indefinitely as long as proper conditions are maintained.

Can You Save Grout?

It is always a good idea to save some grout for any future repairs you may need to do around the house.

Grout comes in handy when you need to do touch-ups for your tiles or hide away any cracks. However, you will need to be careful when storing it in your workshop or shed.

Grout is a material that easily absorbs moisture; therefore, it needs to be stored in a highly sturdy and airtight container.

You can even use a resealable plastic box or a canning jar.

Is Grout Hazardous?

All types of grout pose a  certain risk to your health if care isn’t taken when handling it.

Cement grout is perhaps the most hazardous of it all, especially the kind that has silica molecules in it.

Prolonged exposure to grout can cause skin allergies and even respiratory issues. These occur quite frequently in building contractors who handle grout regularly.

By using protective gear and minimizing exposure, these effects can be avoided, and you can use grout safely to set up your flooring.

Does Toothpaste Clean Grout?

Strange as it may sound, you can actually use toothpaste to clean off grout!

Simply scrub the spot with the grout with a little bit of toothpaste, and you will notice it instantly clear out.

We recommend using whitening toothpaste for some extra polishing. Finish it by rinsing the area using dish soap and a soft sponge, then wipe it clean.

Final Words

The best method of how to dispose of grout is by letting it harden and discarding it in the trash.

However, you should keep in mind that this isn’t the most eco-friendly means of disposal and will significantly increase your carbon footprint.

Instead of getting rid of any grout left behind after you’re done with your repairs, consider storing it for later use.

Grout can easily be stored for over 12 months and used whenever you get cracked tiles. You could also take a closer look at the grouting of your tiles and see if any needs.
