I'm gearing up to install a backsplash using cement board behind my countertop, but I'm unsure about a few things. Since the walls next to the cement board are drywall, how much of a gap should I leave between them? Also, what's the recommended spacing for the cement board itself? I'm planning to use joint compound and tape for the seams where the cement board meets the drywall, and I'll use thin set and fiberglass tape for the seams between the cement boards.
Additionally, the previous owner set up an overhead light above the sink that's linked to the main light switch, and there are no outlets by the countertop. Is it safe to tap into the constantly hot wiring running to the switch to add a junction, running wires to a new switch for the sink light and installing some outlets?

Honestly, drywall is the way to go for a backsplash unless you're dealing with a significant spill risk. You can always use outlet extenders if you're tiling over it. As for your electrical question, it sounds like a bit of a DIY project there. Just check the local codes for how many outlets you need above your counters and whether what you plan is up to code.
You might want to reconsider using cement board for your backsplash. It’s usually unnecessary unless you're planning on really high moisture areas. Drywall works just fine. If you went for cement board, just be cautious with all the joint compound; they’re not typically a great match. Also, you'll be working harder for not much payoff if you're just doing a standard backsplash.
Cement board might be overkill for what you’re doing. Drywall is perfectly acceptable for backsplashes. If you've already bought the cement board, see if you can return it — it'll save you some hassle with the installation process. Plus, for the electrical setup, ensure you follow your local code for outlets, especially spacing them correctly around your countertop.
I appreciate the tip! I thought cement board would be safer, but maybe I should just stick to drywall.
