Important Installation Notes
Staple-Down Installation for Woodloc® 55 Products
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.
- Always begin a Kahrs Woodloc® installation with the tongues facing the wall!
- Proper expansion must be left at all walls.
- As last row generally will not fit perfectly, !Caws recommends dry-fitting first two rows and scribe if necessary.
IMPORTANT!
- Do not open packages until ready to begin installation! Inspect boards before installation. 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.
- Flooring should be installed perpendicular to joists to prevent subfloor sagging. Subfloor must be reinforced to nail down Kahrs parallel to joists.
PRIOR TO INSTALLATION
- See Jobsite/Subfloor Preparation document on webpage and follow all requirements before installation.
- Door casings should be notched or undercut to avoid difficult scribe cuts.
- Sweep or vacuum subfloor thoroughly.
- Once subfloor has been prepared, Kahrs recommends covering subfloor with 15 lb. or higher asphalt felt or rosin paper to retard moisture and help alleviate any remaining variations.
Alternative Staple-Down Installation for Woodloc® 55 Products Only
Now that you have followed the instructions regarding subfloor preparation and also proper installation of Woodloc products you’re now ready to begin with the new alternate staple down method specifically designed for Woodloc® 55 only.
Tools Needed:
- Stapler that accommodates 18 gauge staples with a 1/4″ crown and i” inch to 11/2″ leg. (Typically used for securing plywood underlayment) Similar to Power Nail iS9oU
- Safety goggles
- Portable air compressor
- Air regulator. (Preferably in line type)
- Air hose
- Utility knife
- Kahrs Woodloc® knocking block
- Shims
Installation
The staples will be placed within the extended portion of the groove side of
the Woodloc® joint. It should be placed on the flat surface between the bump
that provides the lock to the Woodloc® system and the groove.
- The air pressure is typically set at 8o-go psi to adequately countersink each of the staples. Depending upon the length of the hose between the compressor and the stapler, along with the thickness of the material, you may have to adjust the air pressure up or down slightly.
- Visually the staple should be slightly countersunk without breaking the wood fibers and without going through the surface. Great care should be taken as to not driving the staple totally through the flat surface. You must also make sure that it is countersunk deep enough that it doesn’t interfere with the next board engaging into the groove or causing a dimple effect on the finished surface.
- Any wood fibers that are visible around the staple should be gently scraped away as to not prohibit engagement of the next board.
- The staples should be placed no further apart than 4″ and no closer to the end joint than 4″.
Final Steps
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 debris such as wood chips, saw dust etc. that were left on wood flooring during installation.
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 damage. See Kahrs Floor Care Guide & Lifetime Guarantee for details (available at www.kahrs.com).
Note: For prefinished oiled floors please refer to Natural Oiled Floors Maintenance and Renovation Procedures at www.kahrs.com
Recoating you Kahrs Floor
Kahrs floors can be renewed without removing the factory finish. As a floor ages, normal wear and tear will cause a floor to lose its luster. This is natural – it happens to all wood floors. To renew the luster and extend the wear layer of the Kahrs floor, recoat with water based urethane coating.
Recoating should be done when necessary. Don’t wait until the finish has worn down. Call your professional flooring contractor for recommendations as soon as you see a wear pattern developing.
Whether coating a floor upon installation or at a later date when it begins to show wear:
- Kahrs recommends calling Arboritec @1-877-416-5972 or Bona Kemi USA @ 1-800-574-4674 for product information, directions, warranties and qualified professionals in your area.
- Do not use water-based urethane over a floor that has been waxed or oiled. If unsure, wipe a small section of the floor with a white rag dampened with mineral spirits to test for wax or coat a test area to check adhesion prior to coating the entire floor. It is imperative, regardless of the age of the floor, to test for adhesion.
- Contact a professional refinishing contractor to assure that the manufacturer’s guidelines will be followed insuring a successful result. The representatives at the toll free numbers supplied above may be able to provide references in your area.
Call Kahrs Technical Line (1-800-ASK-KAHR) for other compatible floor finishes.
