Why it matters
Seams can separate, peak, gap, or become visible when layout, cuts, adhesive, temperature, grain direction, or base preparation are poor. They are a workmanship and planning issue, not just an accessory.
How it is used
Installers plan roll orientation and cuts, trim factory edges as needed, align rows, apply the joining system, and protect fibers from adhesive. Curves and obstacles can complicate the layout.
The money question
How can it affect project cost?
More seams can increase material waste, skilled labor, tape, adhesive, and risk. Roll width, area shape, grain direction, access, and obstacles influence the seam plan.
Common mistakes
- Joining pieces with opposing grain directions
- Placing a seam over an unstable base
- Using excess adhesive or trapping fibers in the joint
Questions to ask an installer or supplier
- Where will seams be located and why?
- Which tape and adhesive system will be used?
- How are seam workmanship problems covered?
