Grout 101: DIY Grout Basics
It’s hard to feel clean when there’s grimy grout in your shower. Unfortunately, the shower is one of the most common areas where grout deteriorates, due to constant moisture exposure. The same applies to the kitchen sink. If your grout is giving you the ick, here is the Grout 101: DIY Grout Basics to replace old, mouldy grout around your sinks, showers, and tiles.
What is grout?
Grout is a filler material used to seal gaps between tiles to prevent shifting and prevent moisture and dirt from getting underneath. There are different types of grout, including cement-based, epoxy, and urethane, each suited for different applications. Basic grout is a mixture of cement, sand, and water. Additional ingredients may be added for durability and flexibility.
Why replace old grout?
It’s no secret that old grout looks terrible; the poor aesthetic of old grout is probably why you’re here. But did you know that replacing old grout helps maintain the integrity and longevity of tiled surfaces?
Over time, grout can crack, wear down, or crumble, allowing water to seep beneath the tiles. This moisture can damage the underlying structure, and lead to mold, mildew, or even rot. Worn-out grout also loses its ability to hold tiles securely in place. To reinforce the stability of the tiles and help prevent them from loosening or breaking, you need to replace your grout.
Old grout is also unhygienic. It can harbour bacteria, mould, and mildew, especially in high-moisture areas like bathrooms.
How do you know when to replace grout?
As a general rule of thumb, if your grout is beyond simple cleaning, it’s time to remove and replace it. Other signs in lude cracks and crumbling. Old grout isn’t pretty… when the time comes, you’ll know.
Can you replace grout without replacing tile?
Yes, as long as you’re gentle with your grout saw or rotary tool, you can replace grout without replacing tile. And if you have a little ‘whoopsie’ moment – you know who to call.
How much does it cost to replace grout?
The cost varies depending on the area and the extent of the damage. On average, professional grout replacement can range from $10 to $25 per square foot. DIY options are cheaper but require time, effort, and a little finesse.
How to replace grout
Here is your go-to method to replace grout in the shower, replace grout on tile floor, and replace grout behind the kitchen sink.
- Gather your tools: You’ll need a grout saw or rotary tool, new grout, a grout float, sponge, and sealer.
- Remove the old grout: Using the grout saw or rotary tool, gently remove the existing grout. Be patient to avoid damaging to your tiles.
3. Apply the new grout: Mix the new grout according to the package instructions. Use the grout float to apply it between the tiles. Fill the gaps evenly.
- Clean the tiles: Wipe away excess grout from the tiles with a damp sponge. Allow it to dry for 24 hours.
- Seal the grout: Once completely dry, apply a grout sealer to protect against moisture and stains.
Pro tip: For areas with high water exposure, like the kitchen sink and shower, replace grout with caulk. Silicone-based caulk is a great alternative to grout. It’s more flexible and provides superior protection from water.
When to call a professional
All DIY jobs are a matter of comfort. Your home is your biggest investment. If you’re ever unsure going into a DIY project, it’s best to call a professional.
Here are some indicators that your project is beyond a simple regrouting job.
- Cracked or damaged tiles: If the tiles themselves are cracked, chipped, or broken, new grout won’t help. Cracked tiles allow moisture to penetrate beneath the surface, which can damage the structure underneath.
- Loose or hollow tiles: Gently tap on the tiles. If you hear a hollow sound or notice that the tiles are loose, the adhesive or mortar beneath them has likely deteriorated. Regrouting won’t fix this problem, and the tiles will need to be reset or replaced by a professional.
3. Mould or mildew behind tiles: Mould or mildew can occur anywhere but it’s most common in the bathroom. If you see mould or mildew growth, it might be a sign water is getting trapped behind the tiles. You’ll need a professional to remove and replace the tiles and address the source of the moisture.
4. Water damage or leaks: Examine the walls and floors near the tiled area for signs of water damage. If you see stains or bubbling paint, the surface under the tile might be compromised and will require professional assessment.
5. Extensive grout deterioration: If the grout is severely crumbled, discolored, or missing in large sections, this could be a sign that the tiles and underlying surface are failing. Extensive grout loss often indicates more significant wear and tear on the tiled surface, potentially beyond what regrouting can fix.
6. Persistent stains or efflorescence: Efflorescence (a white, powdery residue) can appear when water travels through grout and evaporates, leaving minerals behind. If this problem persists even after thorough cleaning, it might indicate moisture issues beneath the tiles, suggesting the need for a professional repair.
7. Warping or bouncing substrate: If the substrate (underlying surface) behind the tiles feels soft, spongy, or bounces, it suggests that the substrate has absorbed moisture and is weakened. This would require replacing not only the grout but also the tiles and substrate.
