Installing your own Mexican sink

Step 9 Wipe off the grout.

Using a big, soft, wet sponge, wipe the excess grout from your countertop. Do this after you have finished grouting. Leaving this step too long (like overnight, don't do that!) will allow the grout to set up and it's like concrete. Work in circles and change your water often, making sure to rinse your sponge well. Your tiles might still look dull, but each swipe should get them looking more like the finished product! It's coming together!

This is really your last chance to leave this grout looking like how it will look on your vanity forever. If there are any goopy danglers, wipe them off now. Leave a nice, neat edge around the top of the backsplash and where your top meets the edge and trim. Tidy up the holes where the faucet and drain stopper will go through. Clean up the overflow divet and the hole where the sink will sit.

Again, follow the directions on the lable for the grout and leave to dry overnight. You want a gradual dry so that the grout doesn't crack and separate anywhere, so frequent misting with water in a squirt bottle allows it to ever-so-slowly dry out.

After it has dried completely (and no cracks, yay!) seal the grout with a...grout sealer. This is a clear, runny liquid that I used a thin paintbrush to apply. I imagine if you had a large surface to cover, you could probably just sponge it on and wipe off the excess, but I used a paintbrush to apply. That way, I knew I hadn't missed a corner.
