Spiral staircases are a beautiful focal point in houses and commercial spaces. If you’re looking to cover it with carpet for noise reduction and added flair, here are the steps you need to take:

How to Install Carpet on a Curved Staircase

Take precise measurements

Measure the size and shape of each step. Though the steps have slight curves, measure a straight line from the top right corner to the top left corner. Then measure the horizontal distance between the bottom corners. Measure the vertical distances between the corners on the left and right sides. Despite the curvature of the step, the step should be the same width from top to bottom. 

Use your tape measure to determine how much space you want on either side of the carpet when it is on your stairs. Subtract this measurement from the measurement for your step width, then use a sharp utility knife to cut out a piece of carpet in the size of your step. Divide the difference between the step width and the carpet width by two, then measure in from either side of the step by that amount and mark it with a pencil — this is where the carpet lines up.

Use adhesives 

You need to apply ample amounts of adhesives on the surface of the treads before you install the carpet. When applying adhesive, start at the end of the treads and then put the carpet on the treads as you apply the adhesives. Do not put adhesives all over the treads and then put the carpet later. Also, do not use fast-acting adhesives when working on your stair treads. Fast-acting adhesives dry so fast that you would not have enough time to arrange your carpet and smooth out all the wrinkles and bunched up areas. Source: DoItYourself

Staple the edges

Install your carpet from the bottom up as well. Place one end of the carpet against the corner formed by the floor and the first riser. Drive staples, one every 3 inches across the bottom edge of the carpet to fasten it in place. Pull the carpet upward and attach it to the tackless strip at the back of the tread. When you reach your first curved step, angle the carpet as necessary to keep the carpet centered on the stairs. One side of the carpet will require more material while the other requires less because of the turn being made.

Keep the tread carpeting flat and single ply, and staple it the underside of the bull nose as before. When you reach the riser, fold the resulting excess carpet over onto itself so that it becomes tucked into a three-layered bundle. Press the bundle against the surface of the riser, and use your staple gun to drive one staple every 3 inches or so to fasten it in place. Continue to the next tread and repeat the process. The treads will be evenly covered, and the risers will hide the rest. Source: Hunker
