1. Remix the Grout After You Set It

When it comes to grouting tile, you need to make sure you’re setting and remixing it properly. Even though it’s tempting to immediately start grouting once the grout is mixed, this could leave you with disastrous results.

What you have to do, after you’ve first mixed the grout, is to allow it to set. This part of the process is called slaking.  This step makes it possible for the water to moisten all the dry elements of the grout completely. You should wait at least ten minutes while this occurs.

Finally, once you’ve waited, you should remix the grout. Depending on its viscosity, you might need to add more water or powder. You want it to have the thickness of mayonnaise.

Be careful when you add water, since you could end up accidentally adding too much and have to start over again.

2. Tape off Areas You Want to Protect

When you’re grouting, accidentally getting any of the grout on unintended areas can cause damage. This is especially the case for paneling, wallpaper, and inset tiles that might have designs on them.

To protect these areas, put tape over them before you start grouting. That way, it won’t get on them, potentially damaging the surfaces while you’re completing your grouting project.

3. Start Small

Grouting Tile - The Purpose of Laying Joints

Once you start to apply the grout to the tile, it starts to harden pretty quickly, with a rate affected by humidity and temperature. Once the hardening starts, you’ll have to quickly wipe off any excess grout before it hardens in the wrong place.

To avoid having to rush to wipe away any misplaced grout, start small. Spread the grout in areas that are 3 feet by 3 feet. Then to finish the grouting in each section, shape the joints and clean the excess grout before you move onto the next one.

4. Force the Grout Into the Joints

Unless you want to spend a long time cleaning tiles and grout in the future, you should force the grout into the joints. This will ensure that they’re all completely filled. To do this, you should apply the grout with the grout float from different directions.

When you’re holding the float against the joints, place the face at an angle of 45 degrees so you can force in the grout.

Once you’ve filled the joints, you can hold the float at close to 90 degrees, after which you can scrape off any excess grout.

5. Shape the Grout

Once you’ve taken the last step, you’re not yet finished with grouting the joints. Now, you have to shape the grout and compact it by taking a tool and dragging it across all the joints. You can use almost anything as a tool.

For example, you could use a toothbrush handle’s rounded edge. You can also use the grout float’s rounded corner.

Basically, you need a tool that’s round and small enough to create a joint that’s slightly concave.

When choosing tools, remember not to use any that are made from metal, as they could leave marks on the tiles or damage them in another way.

If you finish this step correctly, cleaning the tile grout later on will be far less work.

6. Remove the Grout With a Sponge

When cleaning tile grout you have to use a sponge. To start, put clean water in a bucket, dip the sponge, and wring it out well.

Now, place the sponge against the end of a grouted area, making sure not to miss any space in the corners. Drag your sponge, using continuous strokes up along the end of the grouted area.

Then, flip the sponge so that you can wipe the surface with a clean corner and do the same motion next to where you just cleaned off the grout. Continue doing this until you’ve used all the clean corners of the sponge.

Once all the sponge’s corners are dirty, put the sponge back into the bucket and wring it out again. Then, do the same as above until the entire area has been cleaned.

You’ll want to do this entire process two or three times. After the water has evaporated, you might notice that there’s a thin grout film left. You can buff it off using a soft cloth.

7. Don’t Use Too Much Water When Cleaning

One of the biggest mistakes people make when using a sponge as a tile grout cleaner after the job has been done is to use too much water. Even though you want to get it clean, you don’t want to water down the whole project and loosen the tile!

It will also cause the grout color, when it dries, to be uneven.

Be careful not to use too much water. If you notice that there are streaks of water coming down like when you’re washing a whole wall, you’re using too much water. Wring out your sponge and start again.

8. Don’t Scrub When Cleaning

It can also be tempting to scrub hard when you’re cleaning the grout after you’ve applied it to the tile.

However, this will move the grout around instead of properly cleaning it. Use a gentle sponge and press it gently against the grout.

9. Remove Grout Before Caulking

Many people choose to use caulk for the corners of the room because it can handle slight movement and is flexible. If you want your tiles to be installed properly, there are several steps you have to take when using both grout and caulking.

First, after you’ve grouted the entire area, remove the grout in the corners and other places you’re planning to put the caulk. This will make it possible for the caulk joint to be of good quality.

Then, apply the caulk to areas that are vulnerable, such as inside corners and along countertops and the tub.

Remember to choose a caulk that matches with your grout so that it won’t stand out.

10. Seal Porous Tile Before You Grout

If you’re installing porous tile, the grout will stick to it like glue. As a result, it will be almost impossible to clean away when you’ve finished your grouting job. Fortunately, there are products you can use to seal off your porous tile before this happens. If you want your tile to have a matte finish, then you should use a liquid grout release product. This won’t produce a sheen and will protect the porous tile from the grout sticking to it.

However, if you want a “wet” look to the stone or want to enhance its color, you should use sealer. After you’ve applied the grout and cleaned it, apply another sealer coat.

This will both protect your tiles and enhance the stones’ color.

11. Save Some of the Grout

Finally, you should save some of the grout after you’ve completed your grouting project. If you need to do any touch-ups or use the grout for other purposes in the future, having it saved comes in handy. Remember to keep it in an airtight container.
