How to install a Live Edge Slab Countertop

What happens here

Thoroughly sand the live-edge walnut slab to achieve a smooth, blemish-free surface. Start with a belt sander using 50-grit sandpaper to remove any deep mill lines or imperfections. Progress through finer grits using a palm sander: 60-grit, 100-grit, 150-grit, 220-grit, and finally, 3200-grit sandpaper for a polished finish. After each grit, use a dry chamois cloth to meticulously wipe away all dust. Do not use any water, as water can raise the wood grain. For very fine dust removal before the final finish, use a tack cloth.

Goal: Achieve a smooth, dust-free surface on the walnut slab for finishing.

Tools and materials

  • Belt Sander — Initial coarse sanding and removal of mill lines
  • Dry Chamois Cloth — Wiping away dust between sanding grits
  • Palm Sander — Fine sanding with various grits
  • Tack Cloth — Final dust removal before applying finish
  • Sandpaper — Progressive sanding

Hide

again so when we got the rough boards there were clear band lines because these were Mill look like zebra stripes going clear across it this way we had to get rid of those so we spent the day with a belt sander with a 50 grip from there we then went to a palm sander with a 60 grit we moved from the 60 grit up to 100 from 100 we went to 150 from 150 we started to use the 220 and now it's in the final stages I'm going to use an acry polishing kit and I know that sounds dramatic but this is A500 this is 24 or 18 24 and finally 3200 that should give it that shine after we get it just polished to the tea then I come in and I apply a bar top finish it's like a glaze coat not just coat not just coat after coat but this is a I actually pour on and use a squeegee to get it to fill into all the gra the cracks then I'm also going to seal the bark because this is a Live Edge it does have this bark on the side and I've got to get that sealed as well and I'm going to use a spray on poly because it's the only way to get in there I may try to dab it in with a brush but we'll see I'll bring you through that process when we get to one quick thing I'm doing in between each course is I'm using a dry Shamy no moistured nothing and I just go over it and I rub it down with a dry Shamy because what a does is it picks up a very fine layer now you can't see that very well but right in here where I just rub that you can see there's just a tiny bit of dust that's how much we're trying to get this we want to get this to as high a buffer as possible because that is the difference between having something that is amazing and having something that you look at and go I wish I would have put a little bit more time into that for the rest of your life because once the top coat is on the deal is done story's over unless you feel like stripping all that off and using a heat gun and trying to raise it and trying to get all that off which I'm not going to do that I'm going to take a little more time right now I'm going to get this sucker the way I want it so little trick dry shammy not a wet one wet one raises the grain of the wood there you go okay next step in sanding these two countertops down we've hit it with a 3600 grit we did the dry shammy on it picked up all the dust now we're going to take this as a tack cloth just a sticky cloth we're going to rub over it try to get all the teeny tiny fins out of it then tomorrow before we do the finishing coat we'll do it again so we're just going to…
