What condition must be met before installing carpet over a radiant-heated floor system?
Answer: The system should be operating at normal temperature for at least 72 hours, then cooled before installation
Radiant heat floors should operate at normal temperature for 72 hours to normalize moisture content in the substrate, then be cooled to room temperature before carpet installation.
When installing carpet in a doorway between two rooms, how should the seam be positioned relative to the door?
Answer: At the outside edge of the door stop on the pull side
The seam should be placed at the outer edge of the door stop on the pull side so it is protected by the door when closed and hidden from normal view.
What is the purpose of 'cross-seaming' in a large carpet installation?
Answer: Joining carpet widths with seams that run perpendicular to the main seam direction to reduce waste
Cross-seaming runs seams in a perpendicular direction to utilize off-cuts and reduce material waste in large installations.
How far should the nails or pins on tackless strips point toward the wall?
Answer: Angled at 60 degrees toward the wall
Tackless strip pins are angled at approximately 60 degrees toward the wall so they grip the carpet backing and hold it in tension toward the wall.
When a customer wants to install carpet over existing hardwood floors, what is the PRIMARY concern the installer must address?
Answer: Height change at transitions and any loose or squeaky boards that must be secured
Loose or squeaky boards must be secured before installation to prevent noise and movement under carpet, and transition heights must be evaluated to ensure door clearance.
What does a 'delamination' defect in carpet refer to?
Answer: Separation of the primary and secondary backing layers
Delamination occurs when the primary backing (holding the tufts) separates from the secondary backing, causing the carpet to lose its structural integrity.
When calculating carpet yardage for a rectangular room measuring 14 feet by 18 feet, how many square yards are needed (before adding waste factor)?
Answer: 28 square yards
14 × 18 = 252 square feet ÷ 9 = 28 square yards; always convert square feet to square yards by dividing by 9 for carpet pricing and ordering.
