CADInstallation Guidelines
Pre-Installation Notes
Acclimation
All products should be acclimated to the expected average human living environmental conditions, which is 35-55% of relative humidity (R.H). When dry environmental conditions prevent acclimation, because of low air R.H numbers (Nevada, Arizona…), use of humidifies is recommended.
When seasonal site environmental conditions prevent proper acclimation due to higher R.H use of dehumidification may be necessary prior to installation.
Keep the relative humidity of the space between 35-55% at all times (24/7) before and after Installation. To avoid discoloration and heat damage do not expose your hardwood flooring to the direct sunshine. It is a good idea to use area rugs or window shatters.
Job Site Conditions
A near occupied environment should be established for at least five days before any moisture tests and installations are performed. These environmental conditions associated with occupancy must be maintained throughout testing, installation of flooring, and post installation until actual occupancy. The flooring should not be exposed to high humidity or moisture. Prior to delivery of the wood flooring to the job site:
Surface drainage should be directed away from the building

A near occupied environment should be established for at least five days before any moisture tests and installations are performed. These environmental conditions associated with occupancy must be maintained throughout testing, installation of flooring, and post installation until actual occupancy. The flooring should not be exposed to high humidity or moisture. Prior to delivery of the wood flooring to the job site:
Surface drainage should be directed away from the building
The building should be “dried-in” with the roof on and outside windows and doors in place and closed; All concrete, masonry, sheetrock, and framing members should be thoroughly dry;
Basements and crawl spaces must be dry and well ventilated;
In joist construction, outside cross ventilation through vents or other openings in the foundation walls must be provided with no dead air areas;
A ground cover of 6 mil polyethylene film is essential as a moisture retarder and should be in place over of 100% o the earth in the crawlspace;
The interior environment at the jobsite must be at or near occupancy levels;
In warm months the building must be well ventilated, and during winter months heating should be maintained near occupancy levels at least five days prior to delivery of the wood flooring and until sanding and finishing are completed.
Concrete Slab Requirements
The slab must:
• Be properly designed and placed– The slab should be at least four inches thick and it should have a vapor barrier beneath it. It should also have a minimum compressive strength of 2500 psi.
• Be clean – all foreign materials such as oil , asphalt , sealers , paint , loos e materials , plaster/dry wall compound, etc., which can interfere with adhesion or flatness must be removed.
Be flat– maximum allowed variation is 3/16" in 10 feet. All variation must be gradual.
Be smooth– with a steel trowel or light broom finish. The slab surface should not flake or dust.
Directions For Installation
Please read attached information about the preparation of the sub floor before any installation of our hard wood flooring. The finished wood flooring is only as good as the base or sub floor. The make up of the sub floor, actual system components, and the condition and quality of the sub floor system, directly affect the performance of the finished flooring. If the system components are not as recommended, the attachment of the flooring can fail. If the condition of the sub floor is poor, not properly cleaned, not dry enough, and not flat enough, the flooring performance will suffer and require a call back and some type of repair or even re-installation.
