Costco Harmonics Installation on Stairs

The retail chain Costco sells a proprietary brand of laminate floors called Harmonics. The boards are 5 inches wide and about 48 inches long, and they snap together to make a continuous floating flooring. The floor isn’t connected to the subfloor except on staircase, where it has to be glued to avoid slipping. Harmonics generates some of the require such as quarter-round and nosing, but not mirror molding.

Preparation Strategies

Flooring boards are manufactured with a high percentage of wood fibers and react to changing humidity by shrinking and swelling. To avoid curling and warping after setup, you should spread the boards out in the setup space — and at the normal humidity conditions for that distance — for 3 to 5 days prior to installing them. A moisture barrier should separate the boards out of the subfloor except to the staircase, where it would interfere. Have a saw and table saw, each with a new blade, on hand.

Stair Prerequisites

You’ll need four elements for each measure on a staircase. The first is that the riser, that’s the one above it and the section between each measure. The second is and the third is that the nosing, that’s the section that hangs out on the edge of the tread. You can use the boards you’re using to sheath the tread and riser, which are typically made of plywood for setups which will be covered with laminate. The nosing is a part that is distinctive that you must buy. It overlaps the edge of the laminate and must likewise be glued. You’ll also require trimming for each measure, that’s the component.

Installing the Riser, Tread and Nosing

Tread for each step and accurate measurements of the dimensions of the riser enable you to cut the laminate to them, and also also a stair tool is your best way to take these dimensions. It accounts for variations and wall curvature in width. After fitting it and cutting on the riser for the top step, cut and measure the tread and nosing and make certain they fit. You need to glue the tread and nosing to the measure with construction adhesive; the nosing has a slot which holds the riser and therefore you don’t need to glue the riser. Preventing the nosing spaced.

Installing Trim

The staircase won’t seem completed until you cut them. Harmonics manufactures trimming that matches its own laminate products, once it’s surfaced with the fold, along with all the laminate and the wall, which is suitable for completing the interior corners between the tread and the riser. You may want to cut that edge with corner molding, In case your stairway has an open exterior edge. You can use any industrial interior finishing yourself to fit the staircase, staining and trim for this. You might secure it, although the very best way to secure the trim is to glue it with construction adhesive.
