Build a wooden countertop part 3 finished and installed Oct 3, 2013 | Home & Garden, Woodworking | 5 comments 5 Comments Laura on 11/22/2013 at 11:18 AM Jon, I like the countertop and its more economical than granite. But is the poly finish safe for food prep? Can I install an undermount sink if all exposed sides are finished in 3 coats? Lastly, I have some air bubbles in a newly finished oak and maple floor. Will your technique using the finishing paste and 40 grit fine steel wool be safe for my floors? jonpeters on 11/22/2013 at 7:51 PM Well I generally don’t prep food on the counter as much as on a cutting board . My counter top has an under mount sink but the edges tend to get a little banged up from washing heavy pots and pans. Jason on 03/07/2014 at 2:44 PM Hi Jon, I am almost finished my kitchen renovation and I picked up birch countertops, they were the most economical, I was wondering in your opinion, what would be the best polyurethane to use for them? I don’t want to do the oil, I want to seal these bad boys to make sure they have a long life. I don’t have a work shop, so I am working around my family, but I’m trying to do it when they aren’t here. Any tips would be great. Your videos have already answered many of my questions. Have a great day. Jason jonpeters on 03/08/2014 at 2:15 PM Thanks Jason, take a look at (Last and Last varnish )Think they make a strong water born finish.
