How To Finish A DIY Wood Countertop

Using a DIY wood countertop from J. Aaron will help you create a high-end wood countertop, bathroom vanity top or kitchen island top for around $30 per SF plus some elbow grease. It’s the same countertop J. Aaron always makes with all the same custom options available for you to pick from at our design options page. It’s only the raw blank though with none of the finish sanding or sealing done. That we leave up to you. Don’t worry though all the cutouts are pre-cut and all the faucet holes are pre-drilled, it’s just the final sanding and sealing that need to be done.

You’ll need:


Steps to ordering your wood countertop:

Note: We’ll be adding video to this blog post so check back from time to time.

  1. Measure your tops finished outside dimensions including any overhang you would like. We recommend 1-1/2″ beyond the cabinet frame itself. That will give you around 3/4″ beyond the drawer/door fronts. If you would like an extended overhang to use as an eating area we recommend no less than 12″ and preferably 14″.
  2. If you’re going to have a sink we’ll need to have its center line. We don’t need to know where the sink’s opening will start and finish just the location of the center of the sink from either the left or right.
  3. Pick your options like wood species, construction style, thickness, and profile.
  4. Submit all this to us in the form of a simple sketch. We’ll take your sketch and make an exact production drawing that’ll you’ll be able to preview before anything is cut.

If you’re new to the world of DIY we’ll walk you through all this and make it very easy.


Steps to take for finishing countertops that will be used as a cutting/food prep surface:

Note: For more information on what finish you’ll want to use visit our design options page. Conversion varnish is for professional use only so you should only consider the tung-oil or mineral oil/butcher block wax finishes.

  1. For this first step you’ll need to take the countertop blank out of its crate and set it up on something, saw horses work well. Don’t put it inside for this step as it’s about to get pretty dusty. Sand the top using the 120 sand paper. You’ll need to sand the top and sides. If you’ve opted for a decorative profile you’ll need to sand that by hand.
  2. Set the countertop on the base cabinet and screw it down from underneath using 1-1/4″ wood screws.
  3. Apply Howard Brand butcher block wax following the manufactures recommended instructions.

Steps to take for finishing countertops that will not necessarily be used as a cutting surface:

Note: For more information on what finish you’ll want to use visit our design options page. Conversion varnish is for professional use only so you should only consider the tung-oil or mineral oil/butcher block wax finishes.

  1. For this first step you’ll need to take the countertop blank out of its crate and set it up on something, saw horses work well. Don’t put it inside for this step as it’s about to get pretty dusty. Sand the top using the 120 sand paper. You’ll need to sand the top and sides. If you’ve opted for a decorative profile you’ll need to sand that by hand.
  2. When you’ve sanded out all the blemishes turn the top upside down and apply a heavy coat of the tung-oil. Don’t worry about puddles you just want to get as much on there as you can without spilling too much over the side. The goal is for the wood to soak up as much as it will in a 10-15 minute time frame. After it’s soaked up everything it will remove any standing puddles and wipe away any drips from the side. Use the same rag you applied the sealer with so it leaves a heavy coat behind. A dry clean rag will remove too much oil. The surface should still be wet with a layer of oil just no standing puddles. The wood will continue to soak the oil up as it dries.
  3. Let dry to the touch before flipping the countertop over. Do the same thing on the top surface except this time you’ll use a clean cloth to remove as much oil as possible. You can even buff the wood at this point. The goal is to have no residue left behind.
  4. Let dry overnight. Do a light hand sanding (do not use a power sander) using 220 grit sand paper. Use a tack cloth to remove any dust.
  5. Apply a second coat of tung-oil using the same technique laid out in step 3.
  6. Set the countertop on the base cabinet and screw it down from underneath using 1-1/4″ wood screws.

You’re ready to enjoy your wood countertop or kitchen island top and don’t forget to tell all your friends and family that you made it.
