Cordwood Flooring DIY

Cordwood Flooring         

It’s not just for the walls, anymore…” 

A neighbor of mine, Steve, called one cold January evening and said,  “Richard, come on over and see my cordwood floor!”  Needless to say, we hurried over and were amazed.  Lee's Floor 1 with logo.jpgSteve is a mason by training and a general contractor by profession, so he has a knowledge and skill base that is both deep and wide.   The hard maple (Acer saccharum) slices he used were 100 years old.

During the past year, three creative souls have sent me pictures and descriptions of their experiences with “laying” interior cordwood floors.  There are, of course, commercial cordwood flooring options available, but most cordwood aficionados are looking to save money and come away with a building “statement” that “wows” and is attractive.Sunny Pettiz Lutz Cordwood floor 9.jpgSunny Pettis Lutz from Arizona was the next one to send photos and an explanation of her cordwood floor in Arizona.  While Steve Lee’s flooring was fastened to a wooden sub-floor, Sunny’s was glued to a slab-on-grade.Sunny Pettiz Lutz Cordwood floor 1 with logo.jpgFinally, Miroslav Bentley Kubala of the Czech Republic regaled me with photos of his beautiful cordwood storage garage complete with a cordwood floor. Miroslav Bentley Kubala Prague3.jpg from Pintrest site floor manufacture 3.jpgHerein follows a brief explanation of three cordwood floors with three different applications.

  1. Cordwood Floor: Steve Lee After finishing his remodeling project, Steve puzzled over what to do with the floor. He had many options in his construction skill set.  Since J & J Lee Construction had poured the foundation at our cordwood home in 1979 and assisted in the addition of a dormer in 1992, Steve thought a cordwood floor might look good in their new, open concept “great room.”  Here the idea of a cordwood floor came to fruition.

While listening to the local radio station’s “Swap Shop” program, Sharon heard about the availability of a pick-up truck load of 100 year old hardwood barn beams.  Dry as a bone, leveled on two sides, of varying diameters, these, when sliced would become the mosaic pattern for the floor.  Each eight foot timber was cut to three feet and leveled on the ends.  The log was then placed in a band saw and  braced vertically.  (Before cutting, these logs were checked with a metal detector, so any nails or screws could be removed.)  Like slicing a loaf of bread, the logs were then sawn into  5/8″ pieces.  In addition all the sawdust was saved for eventual use in the tile-grouting mixture.  The great room’s 600 sq. ft. sub floor was leveled and the cordwood slices were arranged to create a pattern. When an orientation was resolved (flat side north and south, rounded edge east and west), the construction adhesive, purchased in one gallon pails, was applied to a small section of the floor with a notched trowel. Steve suggests following the manufacturer’s instructions for applying the glue.  Dealing with only a small portion at a time is important so the adhesive doesn’t “skin over”.  The slices were firmly set and secured to the floor and the adhesive was allowed to dry for at least 24 hours.  The next step was packing grout in the spaces between the log end slices.  Steve used commercial tile grout mixed with the sawdust he had collected during the cutting process (the ratio was 80% tile grout to 20% sawdust.

After the grout had dried, an industrial sander was rented and coarse 24 grit sandpaper was used to clean the log faces.  (Steve now suggests sealing the top faces of the cordwood BEFORE grouting, so that the log faces do not become coated with grout.)   Steve sanded until he had a fairly level and smooth surface.  A non-latex, commercial varnish sealer was applied with a lamb’s wool pad to achieve a smooth, level surface.  Steve allowed the varnish sealer to set for 24 hours.  Then he used a scuff pad between coats and reapplied more sealer, until he achieved the surface he wanted.Lees' Floor 2.jpgSteve did the flooring at night and on weekends, but he projects that if someone could work full time on the floor, while allowing ample time for drying of the glue and finish coats, that it could be completed in one to two weeks.   Sharon suggests letting the completed floor set for a week before replacing the furniture.  When the furniture is returned to the room, place pads underneath of legs or pressure points to avoid damage to the final coat.

The floor creates a cozy and beautiful ambiance to the home which is filled with other wonderful examples of repurposing (cabinets, paneling, cedar ceiling, claw foot bathtub, etc.) and is a fine example of using surplus materials in a new way.  These projects show the warmth of wood and the attraction of natural materials. The Lee cordwood floor provides an opportunity for creativity when using recycled wood in the home.  One can only ponder the variations of cordwood flooring that could be produced using different patterning and cutting techniques.

  1. Cordwood Floor: Sunny Pettis Lutz in Arizona    Cordwood flooring by Sunny Pettis Lutz in Cornville, AZ.jpg

   Sunny Pettis Lutz sent some photos of her gorgeous, hand-made cordwood floor.  The following is a detailed list of how she and her husband, Tony, made their floor with legal pickings from the state forest.   “Get a permit to go out to the forest and harvest dead trees. In our area that means Juniper and Pine.  On this floor we are using Shaggy Bark Juniper and Alligator Bark Juniper.” Note that their flooring is on top of a cement slab.   Sunny Pettis Lutz new floor pix 2.jpg  Here are their directions:

  • Cut each piece with a chop saw set at 1 inch.
  • Sort ‘disks’ for clean, useable slices.
  • Remove any loose bark.
  • Sand both sides using a belt sander
  • Prepare concrete surface by sweeping and mopping clean.
  • Begin to layout the disks on the floor getting them as close as possible. Work in 2′ sections.
  • Glue the layout you like using Loctite PL Premium Construction Adhesive.
  • Sand the glued discs, using a belt sander until everything is smooth and level.
  • Use a shop-vac to cleanup all dust and debris.
  • Apply a light coat of polyurethane to the surface of the disks (this is to prevent the grout from adhering to the tops).
  • Grout the spaces with a mix of 80% grout & 20% sawdust.
  • Apply 2-3 coats of polyurethane to finish.  Sunny Pettis Lutz cordwood floor  Floor has 3 coats of oil polyurethane. I'll take pics tomorrow. We are VERY happy with this floor with logo.jpg
  1. Cordwood Floor: Miroslav Bentley Kubala of the Czech Republic installed his cordwood flooring on a concrete slab using the same basic techniques as Steve Lee (see above).   Miroslav Bentley Kubala near Prague25 no logo.jpg

Here are instructions from Miroslav:

  • Clean the floor.
  • Cut slices of wood (hardwood or a rot resistant softwood) 3/4″ to 1 inch.
  • Seal the top of the slices so they don’t get stained by the grout.
  • Glue the slices to the floor
  • Fill the gaps with grout
  • Miro used a mortar/bentonite/acryl mixture
  • Seal the floor with polyurethane

Google “wood block flooring” and “end grain log flooring,” for starters. You’ll find manufacturers, DIY articles and videos.Cordwood countertop by precision floor crafters and Matt Marwick.jpg(Above) Matt Marwick also built this beautiful cordwood countertop.Cordwood countertop BillandVicki Jarratt 3.jpg(Above) Bill Jarratt, an excellent craftsman from Florida, built this bathroom countertop using cedar and epoxy.  Check out his article on how to do this project. https://cordwoodconstruction.wordpress.com/2012/04/15/cordwood-construction-website/      

Plus, for good measure, we have thrown in a cordwood garden pathway!Cordwood garden path.jpgFinally, many folks have seen exterior cordwood garden paths and outdoor cordwood slices laid in the soil.  This is a different animal than interior flooring.  For outdoor cordwood paths, choose a rot resistant wood (like cedar or cypress) and lay the cordwood slices – two inches thick or better – in a soil or sand base. Then tamp the wood pavers in place and smooth and stomp the soil/sand/aggregate, similar to how one would “lay” a brick or stone patio path.

Readers have requested a brief bio, so here goes:

Richard & Becky Flatau built their mortgage-free cordwood home in 1979 in Merrill, Wisconsin. Since then, they have written books, conducted workshops, facilitated the 2005,  2011 and 2015 Cordwood Conferences and provided consultation for thousands of cordwood builders.  Cordwood Construction: Best Practices DVD,  Cordwood Construction Best Practices (print) and Cordwood Conference Papers 2015 are the newest publications available from their online cordwood bookstore.   www.cordwoodconstruction.org
