The best way to stretch carpet during installation involves several key steps to ensure a smooth, wrinkle-free finish. First, prepare the room by removing any furniture and thoroughly cleaning the subfloor. Install tack strips around the perimeter of the room, leaving a gap about two-thirds the thickness of the carpet from the wall.
Next, lay down the carpet padding, securing it with staples or adhesive, and trim any excess. Roll out the carpet, allowing it to extend a few inches up the walls. Begin stretching the carpet using a power stretcher, which is essential for achieving the right tension. Position the power stretcher against the wall and extend it across the room, using the lever to stretch the carpet tightly onto the tack strips.
For smaller areas or corners, use a knee kicker. Place the knee kicker about 3 to 4 inches from the wall, and use your knee to apply force, pushing the carpet onto the tack strips. Trim the excess carpet along the walls using a carpet cutter or utility knife, ensuring a precise fit. Tuck the edges between the tack strip and the wall using a stair tool or carpet tucker.
Finally, inspect the carpet for any wrinkles or loose areas, and make adjustments as needed. Proper stretching not only enhances the appearance but also prolongs the carpet's lifespan by preventing premature wear.
