Furniture project part 5: Grouting.

So after many hours, I did finally manage to finish the mosaic work on that large circle on the left side of the case.

I really do want to stress that what you’re looking at takes hours. You can only put down so many pieces until you have to wait until the glue firms up so you can continue, and that number is much smaller than you think; usually fewer than ten pieces. The glue I’m using is water based, and is honestly not too much different than plain old Elmer’s. The only difference is that this has a slightly longer open, or working time, so you can get the pieces exactly where you want them before the glue sets up. That also means you’re waiting longer for the glue to firm up enough so that you can continue working. Remember, this is only the first side of the piece- I still have five other pieces in which I have to install tile.

Once it was done though, I masked off all three tiled areas. Normally I use blue low-tack painter’s tape but I’m low on it, and so I used ordinary masking tape. I *WOULD NOT* use masking tape for anything involving paint. It’s *terrible* for that purpose. But for this, it’s fine, and when it gets wet, it doesn’t lose its’ grip.

Once everything was masked off, I mixed up some grout. Yes, you can buy it premixed and pre-colored. I have a box large enough to tile a swimming pool in my house, and so I just used what I have (which is kind of a very light gray) and I tinted it using ordinary acrylic paints. To be honest, using powdered pigment would be better, but also more expensive, and I don’t have any in the house. I mixed up just enough grout of each color (really, I just winged the colors- there’s no science here.) and applied the grout with my hand (I was wearing a glove at the time.)

The important thing about mixing grout is it’s sort of like cooking. It has to have the right consistency or it falls apart. You’re only looking to add enough water to form a smooth paste. If it’s the consistency of cream, you’ve gone too far. If you want to know what it should look like, put a bit of toothpaste on a plate and smoosh it around a while. That’s it. You then let it sit out in the bowl for about 15 minutes, stir and *then* apply it.

When you do large areas of tile, you should use tools to apply grout. In areas this small and when the pieces are irregular, your fingers work just fine. Just be sure to wear gloves.

After about 40 minutes or so, you can start to clean off the extra grout. **BE GENTLE**. Both the grout and the glue you’ve used on your tiles are water based. If you scrub too hard, you will pull tiles up as well as grout. If this happens, just re-glue the tile in place, being careful not to drop grout in the hole. I use a little pad and some water. Don’t use too much water. Just enough to dampen the pad, and rinse the pad (and change your water) frequently. You will be doing two cleanings, so it’s not imperative to get all the extra grout off in one shot. Also, remember your grout color will lighten as it dries, so if it looks super dark, don’t worry about it.

About an hour later, I do my final cleanup. On the second pass I just use a paper towel or a rag. You can use even less water- you want to make sure all the grout and haze comes off your tile and not remove much if any grout from between your tiles.

Once this is all done, you can remove your masking tape and clean up any final bits.

Once everything is cleaned up, you can get things prepped for staining, which is our next step.

  1. I never realized how many steps it would take for this project. Nowadays you can purchase this type of design on sticky paper and just plaster it on the wall. Lol

  2. man, you are so crafty! I love mosaics.
