Preparation

Whether you are a DIY'er (Do it yourself) or having your floors installed by a professional, the following is standard information Superior Flooring recommends to ensure your flooring is installed correctly and your warranty remains valid.

Overage

Superior Flooring Hardwood floors are manufactured under hardwood flooring industry standards which permit a defect tolerance of up to 5% of the quantity required. Customers are advised to purchase 5% more than the total square footage required for the application to allow for cutting, waste, and defect tolerance. 

Moisture Levels

Drywall, plaster and concrete must be completely dry and the heating system fully operational with the temperature maintained at 22° C for one to two weeks prior to delivery. All concrete must be cured for at least 30 days.

Preparation

Your hardwood floor must be nailed in place with cleats and the sub floor must consist of plywood or OSB over joists. If the existing sub floor consists of particle board, it will be necessary to overlay it with at least 5/8" plywood before installation.


Measure the moisture content of the sub floor and the hardwood to be installed using a moisture meter. The moisture reading of the sub floor must be between 6% and 12% maximum. Hardwood strips less than 3" wide must be under 4% maximum difference when compared to the sub floor and 2% for hardwood planks over 3" wide. Increase ventilation or use a humidifier to adjust moisture levels before installation. Remove baseboards, quarter rounds, and screw nail the sub floor securely to avoid squeaking. The sub floor MUST be clean, dry, smooth and flat.

Undercut any doorjambs on the bottom of the door frames 3/4" to permit a hardwood strip to be inserted under them.

Your hardwood floor is a natural organic product which is affected by the humidity levels in the air around it. Both before and after installation it will absorb or release moisture. Wood is a natural material that seeks to be in balance with its surroundings. Hardwood destined for use in wood floors are carefully kiln-dried for that purpose. Typically, hardwood will expand during the summer months and shrink in the winter. Acceptable humidity levels of between 40% and 50% should be maintained at all times in the rooms in which your floor is installed.

You will receive the wood for your floor in specially designed cartons that have been stored in dry, heated, well ventilated conditions. These conditions must be maintained throughout shipping, installation, and thereafter.


Important Preparation Steps and Considerations:

  • Drywall, plaster and concrete must be completely dry and the heating system fully operational with the temperature maintained at 22 C for one to two weeks before flooring is delivered to the site. All concrete must have cured for at least 30 days.
  • Your hardwood floor must be nailed in place with cleats and the sub floor must consist of plywood or OSB over joists. If the existing sub floor consists of particle board, then it will be necessary to overlay it with at least 5/8'' plywood before installation.
  • To comply with warranty requirements, 5/8" plywood and 3/4” OSB underlay can be used for up to 16" centers. Three quarter inch plywood can be used for up to 19" centers. OSB sub floors must be installed according to manufacturer's instructions.
  • Measure the moisture content of the sub floor and the hardwood to be installed using a moisture meter. The moisture reading of the sub floor must be between 6% and 12% maximum. Hardwood strips less than 3" wide must be under 4% maximum difference when compared to the sub floor and 2% for hardwood planks over 3" wide. Increase ventilation or use a humidifier or dehumidifier to adjust moisture levels before installation.
  • Remove baseboards, quarter rounds, and then screw nail the sub floor securely to avoid squeaking if necessary. The sub-floor must be clean, dry, smooth and flat.
  • Undercut any doorjambs on the bottom of the door frames 3/4’ to permit a hardwood strip to be inserted under them.
  • Use 2" cleats in 3/4” thick hardwood. Test the hardwood nailer on scrap wood to see that the correct pressure is being used to drive and set the cleats without damaging the hardwood strips.
  • We recommend that the new floor be installed across the joists at a 90 degree angle or 45 degree angle for support and that the installation be done under natural light conditions.
  • Your starting location should be the longest and straightest wall within the room. Roll out the 15 lb felt paper the length of the room, cut it so it touches the outside walls, over lap the inside edges 3 to 5 inches to completely cover the floor space of the room. Felt paper is the NWFA recommendation as an underlayment for the hardwood flooring

Note: Heavy tools or other objects, if dropped on the floor, will damage it. Clean the bottom of any footwear worn during installation.
