Gather Your Tools And Supplies

Before you start grouting your new shower tiles, make sure you’ve got all the necessary tools and materials. Here’s what you’ll need:

  • Grout;
  • Grout float;
  • Tile spacers;
  • Grout sealer;
  • Sponge;
  • Bucket of water;
  • Grout sponge;
  • Rubber gloves;
  • Clean cloth;
  • Painter’s tape; and the like.

Remember: having everything ready will save you time and ensure a smoother process.

Pick The Right Grout

Not all grout is created equal. You’ll want to choose the right one based on your shower tile type and the size of the grout lines.

For starters, sanded grout is ideal for grout lines one part of an inch or wider. It’s more durable and shrink-resistant, making it perfect for larger vertical shower tile options or more expansive areas.

Meanwhile, unsanded grout is best for lines less than one part of an inch wide. It’s smooth, making it easier to work with on delicate surfaces like polished stone or glass tiles.

If you’re unsure, ask a professional at your local hardware store for guidance based on your specific tile.

Prepare The Work Area

Prep work is crucial for getting a professional-looking grout job. Start by making sure your tiles are firmly set in place. The adhesive should have had a full whole day to dry. Then, remove the tile spacers after the adhesive has dried. Be gentle to avoid damaging the tiles.

Next, clean the tiles. Use a clean cloth that’s damp to wipe away any dust or debris. The cleaner the surface, the better the grout will adhere. And finally, tape off the edges. If you’re grouting near walls or fixtures, consider using painter’s tape to protect areas you don’t want the grout touching. This will make cleanup easier.

Prepare The Grout Mixture

Now that the area is prepped, it’s time to mix the grout. Follow the instructions on the grout packaging carefully. The goal is to achieve a smooth, peanut butter-like consistency. Avoid mixing too much at once, as grout can dry quickly.

Tip: If you’re new to grouting, work in smaller batches. This will prevent the grout from hardening before you can apply it.

Once your grout is mixed, let it sit for about 10 minutes before using it. This process, called ‘slaking,’ allows the grout to fully hydrate, improving its workability.

Apply The Grout Properly

Now comes the fun part—grouting the tiles. To begin, you ought to use a grout float. Hold the float at a right angle direction and spread the grout across the tile surface. Work it into the joints, making sure to fully fill each space.

Remember to work diagonally. Move the float diagonally across the tiles to prevent the grout from being pulled out of the joints. This technique ensures an even, thorough application.

Lastly, apply pressure to push the grout deep into the gaps, avoiding air pockets that could weaken the bond over time.

Clean Excess Grout

After you’ve applied the grout, it’s important to clean the excess before it dries on the tile surface. Wait for a couple of minutes then utilize a slightly damp sponge to wipe away the excess grout. Wash the sponge regularly to keep it clean.

Do keep in mind to wipe diagonally across the tiles to avoid pulling grout out of the joints. The goal is to remove the excess while leaving the grout lines intact. You may need to repeat this process several times. Don’t rush—letting the grout set a bit before wiping helps ensure a cleaner finish.

Allow For The Grout To Properly Cure

Grout needs time to fully cure. After you’ve cleaned the tiles, give the grout at least a day or two to fully dry. Make sure the shower area remains dry and undisturbed during this time to allow the grout to harden and set properly.

Seal The Grout

Grout is porous and can absorb water, leading to mold and mildew growth over time. To avoid this, apply a grout sealer once the grout has fully cured. Pick a high-quality sealer specifically designed for shower tiles grout. Some sealers are spray-on, while others require application with a brush.

Next, follow the grout company’s guidelines for application. Typically, you’ll want to apply the sealer evenly across all grout lines and let it sit for a couple of minutes before wiping off any excess.

Remember: properly sealing your grout creates a protective barrier, ensuring your shower stays mold-free and looking great for years.
