How To Fix Grouting Mishaps

How to Fix Grouting Mishaps

Grout is a common material used with tile, and it keeps the spaces between each tile looking uniform. This material can become damaged over time, and it will likely require a bit of repair to restore it to its original state. If you’re dealing with damaged grout, there are some easy ways to fix it yourself. With just a few simple tools and some quick training, you can quickly repair damaged grout and make your floors, backsplash, and feature walls look fantastic again. 

Every tiled surface in your home was also grouted and may need regrouted at some point in time. Grout is integral to every tile installation, protecting the edges of the tiles from damage and keeping moisture from reaching the substrate below the tiles. Unfortunately, there are numerous ways that a grout installation can go wrong. From grout of the wrong consistency to grout that dries too soon, grout mishaps need fixed quickly to ensure a long-lasting installation. We have a wide range of property Melbourne regrouting services at Hitch Property Constructions. 

Properly mixed grout has the consistency of slightly runny creamy peanut butter. When scooped onto the end of a grout float, it should stay put rather than dripping or running back into the bucket. Grout is frequently mixed up too wet and doesn’t cure properly when it is. Soggy grout leaves the finished joints weak and prone to cracking or crumbling, as well as to Efflorescence, a chalky, white appearance. If your grout is runny or too wet, add additional dry grout to the mixture until it reaches the proper consistency for use.

5 Most Common Tile And Grout Problems

Clean tiled surfaces are an integral part of maintaining a safe and healthy home or office space. Kitchens and bathrooms, in particular, have tiled surfaces that are the perfect breeding grounds for fungus, mould and other tile-related problems. These germs can, in turn, cause a variety of contagious infections such as the common cold, flu and enteritis.

White Residue And Stains On Tiles

White residue or stains on tiles can be a common occurrence. This is a result of water penetrating underneath tiles, and the minerals in the water crystallize. This process is also known as Efflorescence.

Efflorescence is generally a porous tile issue. However, clusters of crystals can often appear on grout joints due to grout being a highly porous substance. A tile and grout specialist can identify and resolve the source of Efflorescence. Removal of the unpleasant white residue and stains can be a costly and time-consuming endeavour, which is why it’s a good idea to get the help of experts immediately. Using the wrong products with a DIY treatment on tiles and grout can possibly lead to more issues instead.

Hollow Tiles

Hollow or loose tiles often occur when tile adhesive isn’t bonding the tiles to the wall or floor. This is usually an installation issue when there are gaps where adhesive is missing, under the tiles.

Hollow tiles will eventually break, crack or lift from the surface and can be resolved through a tile repair specialist injecting adhesive under the tiles. In most cases, however, the only solution to this problem is to re-tile. Looking for regrouting services Melbourne on property maintenance? Look no further!

Milky Or Cloudy Tile Surface

A milky or cloudy tile surface can be an indication that the wrong cleaning product has been used for a certain tile type. Be sure to call a professional tile and grout cleaner immediately for cases like this. A professional cleaner will use the correct product and process in cleaning tiles while providing proper advice on products that you can use.


The shower and bathroom offer the ideal environment for mould to grow, making it the most common tile problem. This is due to wet and highly humid areas with poor ventilation, making them a breeding ground for mould. What’s more, soap residue and body oils also create a food source that encourages mould growth.

Once mould growth in porous grout joints occurs, no amount of scrubbing can get rid of it. Using chemicals also does not get rid of mould and will just eat away at the grout, which can just cause more damage.

Mould in shower and bathroom tiles is often caused by a leak. A small hole in grout or cracks in the shower corners can rapidly lead to water build-up and mould ingress. In this case, it’s best to call a leak detection or bathroom cleaning specialist to identify and analyze the cause of mould before proceeding to remove it.

Stained, Dirty Tiles And Grout

Stained or dirty grout is actually often caused by the cleaning process. This is due to grout joints sitting lower than the tiles, pushing dirt and other contaminants into grout joints when scrubbing or mopping tiles. It’s important to always use professional maintenance services to keep them looking new, while regularly mopping with a clean mop, in between professional cleans.

Grout is porous, meaning it can stain instantly and often permanently. The same can be said of tiles. Textured tiles will often retain dirt particles in the surface of the tiles. In cases like this, correct cleaning products and processes applied by expert tile and grout cleaners can assist in resolving the issues.

More Tile Grout Problems

While the tiling is a job that can be completed by a savvy homeowner, there are a few issues that can arise from seemingly minor details. Whether the underlayment is uneven, the subfloor is loose, or the installer used poor technique, these issues tend to show up in the grout after the job is completed. Before setting out for a DIY tiling project, take note of a few of the most common grout defects and take care to avoid them. 


Cracks in your grout can be caused by a number of issues. The worst possible scenario is that the substrate, or material below the tiles, is loose. If the substrate shifts when you step on the tile, the grout and possibly even the tile will crack. Another common cause for this issue is that the grout was not packed into the gap in the tiles properly. If an air gap is left under the grout, it will break and fall into the gap leaving a crack. Finally, cracks can occur if the grout is mixed with too much water or left to sit too long before use.

Uneven Coloring

Ideally, grout has a consistent colouring from one side of the room to the other. In practice, it isn’t unusual to see fluctuation in colour. This issue can be caused by many issues. Most commonly, the error comes from issues mixing the grout. If only half of the bag is used to mix a batch, it is possible for the colour pigment to be uneven from one batch to the next. Also, if extra water is added into a batch of grout to rehydrate it during the job, the colour will be lighter after the water is added. Another common cause is using dirty water or a dirty sponge to wipe off the tiles during grouting or removal of grout haze.


Grout is a very porous material, so it tends to absorb moisture, which can cause staining. If the grout is not properly sealed after drying, you’ll likely have this problem. The procedure is fairly quick and easy. Once your grout is dry, and you’ve cleaned your tiles of grout haze, apply grout sealant to your lines using a sponge or applicator brush. Wait the recommended time listed on the bottle for the sealant to penetrate and wipe it off with a clean rag. Repeat this procedure yearly to prevent stains in your grout.


Grout, being the low area between your tiles, tends to accumulate grime and get pretty nasty. Its porous, craggy surface makes cleaning notoriously difficult. While you won’t be able to simply pass a mop over the floor and call it done, cleaning dirt and grime from your grout doesn’t have to be a nightmare. Mix a solution of ½ cup of baking soda, ¼ cup of vinegar and 7 cups of water. Spray the mixture onto your grout lines with a spray bottle and work it in with a sponge or old toothbrush. Wipe the tile dry with a cloth to finish the job. For tough stains, mix a solution of one part bleach to five parts water and scrub until the stains are gone.

How to Grout Tile Quickly

Grout not only makes tile surfaces in your home more attractive but also it improves the structural integrity of the tiles. Grouting tile may seem like an intimidating task, but even if you have never laid grout before, you can do the job yourself if you use the right tools and the right technique. Grouting does not require professional assistance, and you may be surprised to learn that you can get the job done in very little time.

  • Remove any existing adhesive or stuck-on impurities from your grout lines. You can quickly do this using a razor knife or utility knife. You do not have to remove every piece of dirt, but any bits of unwanted sticky residue or anything that protrudes from the surface of the joint.
  • Moisten the grout lines with water. This will help the grout to adhere more readily once you lay the cement. Do not saturate the joints, but just dampen them lightly right before you get to work.
  • Pour 2 to 3 inches of water into a bucket and then add enough powder grout to cover the liquid. Mix the water and grout to a firm consistency. If necessary, add more water or more grout until you have perfect consistency. You should try to achieve the consistency of a thick cake batter, according to home improvement expert Tim Carter.
  • Scoop some grout onto the surface of a groat float. A grout float is a flat, specialized trowel made for laying grout. You can find one at your local home improvement store. Push the grout into the joints between the tiles, holding the float at a 45-degree angle and applying pressure to the tile surface. Push the float along the grout lines in swift, fluid motions to quickly apply the grout. Do not worry about getting grout on the tiles themselves.
  • Wipe any excess grout from the float and then push the float diagonally along the tiles to remove much of the grout that has collected outside the joints. Hold the float almost completely flat while performing this step. This will make your cleanup job much faster and easier.
  • Wipe the tile with a damp sponge to remove the excess grout. Since you previously removed the majority of the grout from the tile, you should be able to accomplish this in little time. Once you finish grouting the entire tile surface, walk away and wait at least two hours before lightly walking on the grout. Wait at least a week before allowing the grout to come into contact with moisture.

Guide On How To Replace Grout

Cracking and crumbling grout falling from your tiles is often a sign of an improperly mixed or installed grout. When this occurs, water can seep between the tiles, cause damage to the wall behind the tiles or loosen the tiles, causing them to fall from the wall. You must remove the old grout before you replace it with new grout. Make sure to use the correct grout for the tile application, such as unsanded grout with latex additive for bath tile or sanded grout for floor tile with joints wider than 1/8 inch.

  • Remove old grout from between the tiles with a grout saw, an oscillating tool with a carbide grout blade or a rotary tool with a carbide grout removal bit. A grout saw requires you to move the saw back and forth manually to remove the grout, while a rotary or oscillating tool requires less effort.
  • Clean the space left between the tiles with water and an old toothbrush. Wash the area well with fresh, clean water and allow the tile surface to dry for 24 hours.
  • Pour powdered grout into a bucket. Add a small amount of water and mix the grout with a margin trowel. Continue to add small amounts of water until the grout reaches the consistency of peanut butter. Hitch Property Constructions has a wide range of regrouting services. 
  • Allow the grout to sit undisturbed for about 10 minutes. Use the margin trowel to remix the grout. Do not add more water.
  • Scoop some grout from the bucket with a rubber grout float. Hold the float at a 45-degree angle against the tile and sweep the float diagonally across the tile, pushing the grout into the grout lines.
  • Remove the excess grout from the surface of the tiles with a clean grout float. Hold the float at a 90-degree angle against the tile. Sweep the grout float across the tiles diagonally, picking up the excess grout.
  • Wait about five minutes for the grout to dry. Press your thumbnail into the grout; if it leaves an indentation, wait another five minutes and check the grout with your thumbnail once again. Wait until your thumbnail does not leave an impression before cleaning the tile.
  • Clean the tile surface with a water-dampened grout sponge. Use short strokes to remove any remaining grout, rinsing the sponge often with clean water.
  • Wipe the tile surface with a soft damp cloth to remove any grout haze. Buff the tiles with a soft dry cloth immediately after removing the haze.
  • Fill a general-purpose spray bottle with fresh water. Mist the new grout two or three times a day for three days.
  • Apply grout sealer with an artist paintbrush. Clean any sealer from the surface of the tile immediately. Let the grout dry for at least 24 hours.
