1. First you’ll have to clean up that big mess you made yesterday. Grab a vacuum and a bucket of warm water. With the grout saw, remove any areas of mortar in the seams that are too high to accept grout. Vacuum all dust, wipe down mortar on tiles using the grout sponge.

2. Mix grout. We learned about slaking yesterday, so you know what time it is. Enjoy.

3. Throw a glob of grout on the floor and work it into joints at an angle. The key is to fill the whole joint, not just the surface.

4. Wipe up excess grout off tile with the clean edge of the float.

5. For edges and corners, you may need a margin tool, but fingers also work fine.

6. You’ll want to allow about 15 minutes for grout to set before you start to wipe the tiles down with sponge. Think about this as you’re grouting. Don’t do the whole floor at once so it dries and makes it more difficult to clean.

7. Cleaning is hell. You’ll need to replace water in bucket several times. Be careful where you dump dirty water as it can clog sewer lines. Just keep wiping and drying, trying not to drag the grout out of the seams. You only want to clean the tile, not the grout.

8. Wait 24 hours, then seal.
