Kitchen And Bathroom Renovation : How to Build a Butcher Block Countertop 06
Option: If you’re installing an undermount sink, mark a centerpoint for drilling a hole to accommodate the faucet body following the recommendations of the faucet manufacturer. A 13⁄8"-dia. hole is fairly standard.
Seal the edges of the sink opening with a varnish as instructed by the butcher block manufacturer or by coating it generously with pure mineral oil or tung oil for a natural finish. Let sit for 15 minutes then wipe off the excess with a clean, lint-free cloth. Let it dry for 48 hours. Repeat six times, letting it dry thoroughly between coats.
Add backsplash of your choice and caulk between the new countertop and the backsplash area with silicone caulk.
Install the faucet and sink and make the water supply and drain hookups.
