Parquet Flooring Installation (2023)

Spreading Adhesive

Apply glue using a trowel.

NOTE: Clean adhesive from the surface of the floor frequently using the recommended adhesive cleaner. Use a clean towel, frequently changed, to prevent haze and adhesive residue. Maximum Adhesive Working Times:

  • Urethane Adhesive - 60 minutes (Always read container label before proceeding)
  • Polymeric Resin Adhesive - 90 minutes (Always read container label before proceeding)
  • All adhesives' open times and curing times vary depending upon subfloor porosity, air movement, humidity, and room temperature. Urethane adhesive has a shortened work time in high humidity environments, whereas polymeric resin adhesive working time will be lengthened. In areas of low humidity, the open time will be longer with urethanes and shorter with polymeric resins. Adjust the amount of adhesive spread accordingly. The adhesive should not be applied if subfloor or room temperature is below 65° F (20° C).
  • Spread sufficient amounts of recommended adhesive with the recommended trowel (figure below) in an area that can be covered in 60-90 minutes.

Hold the trowel at a minimum 45° angle (figure below) firmly against the subfloor to obtain a 50-60 sq. ft. per gallon spread rate.

  • When not in use, keep the adhesive container tightly closed to prevent thickening. Thickening of the adhesive will cause difficulty in spreading the adhesive.
  • Proper ventilation within the room must be provided. An electric fan is helpful.

NOTE: When installing UNFINISHED SOLID WOOD PARQUET flooring, allow a minimum of 36 hours adhesive curing time before applying seals, stains, and finishes to unfinished flooring. Trowel filling and fillers are required to reduce the possibility of panelization caused by the finish "gluing" the slats together. Test the moisture content of the wood per the stain/finish manufacturer's recommendations. Avoid installing from the surface of the flooring. If necessary, distribute weight using a kneeler board.

Please follow the technical specification for working time for adhesive.

Czar Floors recommends Bostik's Best or Sika SikaBond adhesive for most applications.

For installation over concrete, radiant heated floors, soundproofing, we recommend using Bostik Ultra-Set SingleStep 2. It combines hardwood adhesive with moisture vapor barrier and sound reduction membrane.

Listed adhesives are the only adhesives tested and certified by Czar Floors. Use other adhesives at your own risk. Czar Floors does not provide a warranty on subfloor separation for other adhesives. Those adhesives are available at the specialized flooring distributors or can be purchased through Czar Floors.

Installing parquet modules

  • It may help to dry lay the section of the floor first to get an idea. This is especially helpful with artistic parquet. Use drawings as your reference.
  • Immediately lay the floor tiles on the newly spread adhesive. DO NOT lay the floor tiles on the dry adhesive (Always lay the floor tiles on wet adhesive). If the adhesive becomes too dry, scrape up the old adhesive and spread more. Installing on wet adhesive eliminates rolling the floor with a heavy roller. The working time for the adhesive is 60-90 minutes. Working time will vary depending on the job site conditions. IMPORTANT: Stand or kneel on the subfloor during the installation to avoid shifting the tiles. TIP: Slightly slide tile diagonally about 1" back and forth to ensure good adhesive spread. Tile can be temporarily secured with finishing nails.
  • PROPER PLACEMENT OF THE FIRST FLOOR TILE IS THE KEY TO THE ENTIRE INSTALLATION. Carefully place a parquet tile at the intersection of the two chalk lines. Use spare boards to align and secure the tiles, as shown in the picture below. Start at the center of the room in one of the quadrants using chalk lines and temporary boards as a guide.
  • Continue laying the balance of the floor tiles along the starting quadrant. Align each floor tile squarely.
  • Do not push or shove the floor tiles too strenuously, as this could cause the other tiles to move. Realign them and proceed with the installation. Use pieces of wide blue masking tape to temporarily hold the tiles to avoid "floating" of the tile in wet adhesive. This tape can be removed after the glue is cured or sanded off. Alternatively, you can secure the parquet module with two-three staples (not nails) shot at the side of the tile.
  • Avoid hammering or forcing the floor tiles together as this will destroy the built-in expansion spaces and may destroy the squareness of the floor tile. You may use a rubber mallet to tap the tiles.
  • After laying the floor tiles across the first starting area, trim the last floor tiles as needed to obtain the proper 1/2" expansion space next to the walls. Use a small band or saber saw for final trimming. Firmly secure each floor tile when cutting with a saber saw.
  • During the installation, occasionally remove a flooring piece from the subfloor and inspect the back for proper adhesive transfer. An adequate adhesive transfer is necessary to ensure sufficient holding strength. DO NOT REMOVE PROTECTIVE PLASTIC TAPE ON THE TILE SURFACE. The tape will be removed during first-pass sanding.

Diagonal Parquet Tile Installation

A diagonal pattern is recommended in corridors and in rooms where the length is more than one and half times the width. This diagonal placement minimizes expansion under high humidity conditions but does not change the requirements for expansion at the wall lines. It takes a bit longer to fit trim but gives your customer diamonds instead of squares and is worthy of a labor up-charge.

  1. Mark on the subfloor along the longer walls at the middle point of the room. Snap a chalk line between these two points to establish a primary line.
  2. Mark on the subfloor along the shorter wall at the middle point of the room. Snap a chalk line between these two points at the center of the room to establish the secondary or perpendicular line. Adjust secondary line using the 3-4-5 Pythagorean Theorem. The two lines you have just drawn are the most important. All other lines will be measured from these lines.
  3. To establish two 45º lines, measure a 1/2 from the center of the room along the longest wall and place a mark on each line in both directions. Use trammel points or a beam compass to make this step easy and accurate. Using the same measurement, draw an arc from each of the points established in Step 3 on the subfloor where 45º line will cross, showing four bisected arcs. Snap chalk lines between these points. These new lines should go directly through the center of the room. The first four parquets should be meeting at the dead center of the room.
  4. Install using a pyramid or stair-step pattern. Wood parquet “squares” are not always square. They are not “die-cut” or stamped out. They are cut on saws, and the wood is affected by moisture changes. Therefore, they will not be perfect and must be installed in the pyramid pattern — not row by row.
  5. Place the parquet unit carefully at the intersection of your two lines. Lay the next units ahead and to the right of the one along the lines. Then continue the stair-step sequence, observing the corner alignment of new units with those already in place. As it is placed, each unit should be adjusted to keep the corners true or "on point" and, if necessary, give up a tight fit along the sides. Install in a quadrant of the room, leaving trimming at the walls until later. Then return to the base lines and lay another quadrant, repeating the stair-step sequence. Install the last quadrant from the base line to the door. A reducer strip may be required at the doorway if transitioning to another floor. To lay row-by-row and tight guarantees that the variations continue to compound themselves and produce disaster after five or six rows.
  6. Build the field by maintaining the pyramid and enlarging it, with constant reference to the working lines. Be sure to “seat” each unit in the adhesive. Adjust the units as you go and stay within the limits of the adhesive.

Completing Installation

  • When the starting area has been completed, including cutting to the wall, proceed to the second laying area.
  • The second laying area is quite simple as you now have sufficient floor tiles installed to resist floor tile movement.
  • Again, cut the last floor tiles to allow a 1/2" expansion space from the end wall.
  • Proceed by laying other areas, repeating the installation procedure of the starting area. Trim out each laying area before proceeding to the next area.
  • Maintain the 1/2" expansion space around the perimeter of the room and all fixed objects.
  • Avoid pressing heavily or stepping on the recently laid floor tile as this may destroy the ridging of the adhesive and positioning of the tile.
  • It is normal to have some gaps between tiles and wood pieces after this phase. Use quality wood patches and Full-Trowel Fillers to cover those gaps. Full-Trowel Filler is thinner than Wood Patch and designed to spread across the wood floor's surface. Just pour a workable puddle and trowel the floor, going back and forth across the cracks and voids to ensure deep penetration, removing excess filler as you go. Three 1/2-gallon pail fills up to 3,000 square feet. Bona makes an excellent line of wood fillers.
  • Allow a minimum of 36 hours drying time before moving furniture or walking on the newly laid parquet floor.

Sanding of wood parquet

When sanding a hardwood floor where grain pattern differ such as parquet or inlay cut at a 45-degree angle to the floor in two directions. Third cut along the room's longest side. Possibly a fourth pass, using a floor polisher and hard plate. Extra hand-sanding work may be required.

Use a drum sander to remove the transparent plastic tape from the surface of the face-taped parquet. Three sandings with progressively finer paper are recommended. Pay attention if several different kinds of wood used in the parquet as softer woods may sand faster than harder species and may develop uneven surface. Small areas with medallions or borders are better sanded with the floor polisher and sandpaper on a hard plate.

When using mixed media such as stone and parquet, consider using plywood blanks inserted in the place of marble or stone during the sanding phase.

For in-depth instructions, read the excellent Floor Sanding manual by Lägler - leading floor sander manufacturer.

Stain and Finish

Stains are not recommended for the parquet that used various wood species. Many species accept stain differently. Clearcoat Polyurethane or wax finish can be applied.

One-Two coats of fast-drying sealer can be applied. To enhance the appearance and deepen the color of the wooden floors, consider using Bona Prime Amberseal sealer. Always use a sealer and finish from the same manufacturer.

You can use pretty much any Water-based, Oil-based, or Hard Wax floor finishes with our flooring.

Czar Floors recommends finishes made by Bona, such as Traffic HD or Street Shoe NXT by Basic Coatings.

Parquet Floor Maintenance

Vacuum your floor as often as you would your carpet. Don't use rotating brushes - turn it off if possible. If the hard wax is used for the finish, periodically buff the floor using paste wax.

It is essential to maintain the relative humidity level in the 36 to 60% range. Use portable or HVAC built-in humidifiers during the heating season.

Use cleaning products specifically formulated for the hardwood floors, such as Bona Pro

Installer/Owner Responsibility

Beautiful hardwood floors are a product of nature and, therefore, not perfect. Our wood floors are manufactured in accordance with accepted industry standards, which permit a defect tolerance not to exceed 5%. The defects may be of a manufacturing or natural type.

  • The installer assumes all responsibility for the final inspection of product quality. This inspection of all flooring should be done before installation. Carefully examine the flooring for color, finish, and quality before installing it. If the material is not acceptable, do not install it and contact us immediately.
  • Before installing any hardwood-flooring product, the installer must determine that the job-site environment and the sub-surfaces involved meet or exceed all applicable standards and recommendations of the construction and materials industries. These instructions recommend that the construction and subfloor be dry, stiff, and flat. The manufacturer declines any responsibility for job failure resulting from or associated with sub-surface or job-site environment deficiencies.
  • Before installation, the installer/owner has final inspection responsibility for grade, manufacture, and factory finish. The installer must use reasonable selectivity and hold out or cut off pieces with defects, whatever the cause.
  • Use of stain, filler, or putty stick for defect correction during installation should be accepted as standard procedure.
  • When the flooring is ordered, at least 10% must be added to the actual square footage needed for cutting and grading allowance.
  • Should an individual piece be doubtful as to grade, manufacture, or factory finish, the installer should not use the piece.
  • The use of appropriate products for correcting subfloor voids should be accepted as a standard industry practice.
