Underlay mints
- Kars Quiet Stride
- Direct Glue-Down: Install QuietStride wall to wall, butt all seams together (do not tape seams), directly adhering to subfloor with a premium multi-purpose adhesive. Fully adhere Kahrs flooring to underlayment using approved adhesive and trowel (see Glue-Down Installation for details). Note: an approved concrete sealer must be used if calcium chloride test exceeds albs as recommended by the manufacturer of that product.
- Direct Glue-Down over “float-in” underlayment: First install 6 mil polyethylene plastic loose-laid, seams over-lapped 8″. Run plastic up wall 2″ (trim excess after installation, before installing trim). Loose-lay QuietStride on top of plastic, wall to wall, butt all seams together (do not tape seams). Fully adhere Kahrs flooring to underlayment using approved adhesive and trowel (see Glue-Down Installation for details). Note a concrete sealer must be used if calcium chloride test exceeds 3Ibs. as recommended by the manufacturer of that product
Important: Kahrs does not guarantee the performance of any non-Kahrs branded underlayment.
TOOLS & TECHNIQUES
Important Installation Notes
Please see our website – www.kahrs.com for Kahrs Floor Care Guide and Lifetime Guarantee.
Installation:
Glue down:
Installing Kahrs floors with the Glue down method requires no expansion breaks
in the floor and is not limited in size. A 1/2″ gap at perimeter walls is
required to allow engagement of last boards.
Kahrs Flooring is approved for installations in ‘A bathrooms only ( no bathrooms including showers or bath tubs)
Expansion in Large Areas:
You may be able to attain the necessary added expansion by trimming the wallboard (i.e. sheetrock) or raising baseboards before installing floor. This will allow the floor to expand underneath the wall. For complete information please refer to Required Expansion Reference Charts on pages 8 and 9 in the Layout section of this Guide. A Kahrs floor requires 1/16″ expansion for every 3′ across width and 1/16″ expansion for every 9′ along length. For example, a 28′ x 28′ space requires an expansion gap of 9/16″ around the edge of the flooring.
Adhesive Tape on Kahrs Floors
The use of adhesive tape on any Kahrs floor for any reason (i.e. to fasten temporary protection) is not recommended and is not covered in our warranty.
Additional Finishing Coating:
For additional wear protection, a waterborne urethane finish is compatible with ‘<airs factory finishes. Contact Arboritec (1-877-416-5972) or Bona Kemi USA, Inc. (1-800-574-4674 ) for recommended products, application and warranty information. Follow manufacturers instructions for recoating a prefinished wood floor. Kahrs International, Inc. does not guarantee the performance and/or durability of these products.
Recommended Adhesives:
Please contact your local adhesive distributor for a recommendation of the proper adhesive to use for the intended purpose. They will also be able to supply you with the spread rate, open times, shelf life and most importantly guarantee on the product.
Glue-Down Installation for Woodloc®
Notes:
- Kahrs flooring is covered by a Limited Lifetime Warranty. However, Warranty coverage may be lost due to failure to strictly follow all installation instructions and recommendations or the use of improper materials or tools. READ ALL INSTRUCTIONS CAREFULLY.
IMPORTANT!
- DpaQtQp_gniaskageauntilxeclshaQJ2k begin Jinstallation! Inspect boards as you go. Kahrs flooring is sealed at the factory with a 7% moisture content. Opening cartons to acclimate the flooring (as with some solid strip flooring) could result in a difficult installation.
- As an installer, it is your responsibility to be aware of the grade, Relative Humidity of the room, and moisture content of the subfloor. You should check that each plank is free of damage or manufacturing defects. Any unusable boards should be set aside for later replacement.
- Tip: Dry-lay first two rows to familiarize yourself with Woodloca5S
Prior to Installation
- See Jobsite/Subfloor Preparation section and follow all requirements before installation.
- Door casings should be notched or undercut to avoid difficult scribe cuts.
- Sweep or vacuum subfloor thoroughly.
- Recommendations for adhesives should come directly from the adhesive manufacturer of choice. They can supply information regarding the intended use and warranties.
Step i – Layout
1.1 Using starting wall as reference, snap chalk line on subfloor at
distance X from wall as shown in Fig. 1.1. To calculate X, engage two
boards together (refer to Step 2.1 on locking procedure) and measure total
width, including exposed groove, then add 1/2″.
1.2 Align straight edge (Kahrs board or any solid material with straight
edge) with chalk line and secure to subfloor (Fig. 1.2)
1.3 Measure 1/2″ from starting wall and snap another chalk line (Fig. 1.4 ).
1.4 Spread adhesive in area between straight edge and second chalk line
(Fig. 1.4). Use only as much adhesive as can be used during manufacturer’s
open time of adhesive.
Step 2 – Installation
2.1 Start with tongue side facing wall and long groove side directly up
against straight edge as seen in Fig. 2.1. Lay board into adhesive. Remember
to allow 1/2″ expansion gap at wall.
2.2 Hold next board against first board at approximate 452 angle and lay
flat on floor as shown in Fig. 2.2. Continue in this manner for entire first
row, allowing for 1/2″ expan-sion gap. Insert shims at both ends.
2.3 Use cut off from first row to start second row (Fig. 2.3). With
groove side facing first row, hold board at approximate 452 angle and press
inward, completely engaging long side joint. Ensure end joint stagger from row
to row is a minimum of 20″ for 3.4mm and 15mm and a minimum of 12″ for 7mm and
iomm flooring.
2.4 Leave tongue side of board raised – DO NOT lay board flat into adhesive until all boards in row are fully engaged on long side.
2.5 Engage short end of next board as in Step 2.2 (Fig. 2.2). Lay long side in line with tongue of adjacent board in first row.
2.6 Since last row will generally not fit perfectly, scribe the row and
cut to fit, allowing 3./4″ (minimum) for expansion gap (Fig. 2.6a).
Close seam tightly by pressing board against adjacent board. If necessary,
use Last Board Puller (sku 710203) to assist with engagement (Fig. 2.6b).
Continue until row is complete.
2.7 After first two rows are installed, ensure expansion gap between
boards and walls are shimmed securely (Fig. 2.7, below). If recommended by
adhesive manufacturer, roll flooring with ioolb. roller to ensure contact
between flooring and subfloor. Place weight (e.g., unopened cartons) along
perimeters until adhesive sets up. Remove straight edge.
Step 3: Subsequent Rows
3.1 Once starting rows are firmly in place, apply adhesive in a “wet lay”
method. Do not apply more adhesive than can be used within open time of
adhesive. Immediately place flooring in “wet” adhesive and proceed with
installation (Fig. 3.1).
Step 3: Subsequent Rows (con’t)
3.2 Start each row with cut off end of last board from previous row (Fig. 3.1).
3.3 DO NOT lay board flat into adhesive until all boards in row are fully
engaged. To assist in engaging, use Woodloc Glue-Down Knocking Block (sku
710281) to engage long joints, as shown in Fig. 3.3.
Tips
- After first three rows are laid, have one installer work on installing flooring while others spread adhesive and cut boards as needed.
- Installation of Woodloc® is easier while working on already installed flooring, as shown in Fig. 3.3.
- Working in this manner lessens chance of accidentally transferring adhesive onto flooring surface, thereby reducing clean-up time.
- For doorway installation instructions, see Woodloc® Float-In instructions.
After Installation
Remove expansion shims and use required Kahrs moldings and/or trim pieces to
cover expansion space (Fig. A). Always nail moldings to wall, never to
flooring!
Clean Up
- Immediately clean any adhesive spilled on wood flooring during installation. Follow adhesive manufacturer’s recommendations.
Curing
- Keep foot traffic to absolute minimum until adhesive is fully cured (follow mfg.’s recommendations).
- Wait at least 24 hrs. before placing furniture back in room and resuming normal traffic.
Maintenance
Clean floor using dry dust mop or damp (lightly misted or well rung out) mop or cloth. Regularly use Kahrs Wood Floor Cleaner for best results. Do not use oil soap or water-emulsion, self polishing waxes. Never wet mop floor. Place Peel & Stick Floor Protectors on furniture legs to prevent dam-age. See K5hrs Floor Care Guide & Lifetime Guarantee for full details (available at www.kahrs.com).
NOTE: Oiled floors must be oiled with Kahrs Satin Oil I71o55/1 after installation and prior to use.
