Installation
Acclimation & Preparation
​
Even though our wood is kiln-dried to 6%, seasonal changes will continue to vary the moisture content. The flooring should not be exposed to excessive humidity and moist conditions. The moisture content of the subfloor and the new wood flooring should not vary by more than 2-3%.
​
Particle board of any thickness is not recommended for the subfloor. Bring the product and the surrounding atmosphere to a mid 60 degree temperature for a week and make sure the environmental humidity is kept at mid 38-42% before, during and after installation.
Installation for 3/8" Floors​
​
Our 3/8" products should be installed on plywood with 10% moisture content or less. OSB should be covered with 1/4" lauan underlayment, stapling every six inches. It is extremely important that the floor be clean and dry.
​
Begin by undercutting all door casings and jambs. Start on the longest outside wall and snap a chalk line to serve as your straight edge for the first row of planks. Select your straightest planks.
​
Apply a 1/4" bead of approved construction adhesive in an "S" pattern along the back of the plank. place your board tongue side out, leaving a 1/4" space along the wall....
​
​
​
....While holding the nailer at a 45 degree angle, nail the tongue edge every 4" with an 18 gauge pin nailer (face nail the starter row along the walls, base shoe will cover this later).
​
Select the second row, making sure that the end joints are staggered. Glue the back of the piece and place the board as before. Using a block of wood and a hammer, gently tap the edge of the board so the groove slides over the tongue and is snug (do this on the end also).
​
Continue installing each new row as previously mentioned, making sure to glue, tap, snug and nail every 4". Talk to a radiant tech at Launstein's before nailing over a radiant system.
Installation for 3/4" Floors​
​
This is a traditional nail down application, however, anything over 7 1/2" should also be glued with our recommended solvent based construction adhesive. A light sanding is needed after installation. Installation procedures can be found on the National Wood Flooring Association website.
Finishing On-Site
​
Pre-sanded, micro beveled flooring will still need a mild sanding before finishing to remove scuffs, etc. Square edge flooring will require additional sanding.
​
After sanding, vacuum thoroughly. Allow the dust to settle and wipe down to remove the fine dust.
​
If using an oil-based polyurethane three coats of finish will be needed. Pour the finish into a paint tray and spread it onto the floor down the length of the board using a pulling motion.
​
Repeat the mild sanding and cleanup before the second and third coat. Remember that part of having a smooth final product depends on having a clean surface before applying the finish.
Radiant Heat
​
Radiant heat is very popular and there are many different systems. There are, however, guidelines to be followed. Be sure to talk to our radiant tech early in the decision process to achieve the best final outcome.
Concrete Subfloor
​
All concrete must be thoroughly dry before any wood flooring can be applied. The 3/8" products can be used if plywood is anchored down first. The 5/8" engineered flooring is quite often used for direct glue down.
​
Remember that concrete, even if well cured, can radiate moisture at certain times of the year, so a moisture barrier will be needed. Please contact our staff for recommendations.
