The recommended method for sealing seams on stretch-in carpet is to use acrylic, latex, or thermoplastic adhesive. These types of adhesives provide a strong bond that is flexible enough to accommodate the natural movement and stretching of the carpet fibers. They also typically have properties that allow them to withstand the stresses placed on the seams, reducing the risk of separation over time.

Using the correct adhesive enhances the installation's durability and overall appearance, maintaining the integrity of the seams under foot traffic and other stressors. This choice of adhesive is critical, as it contributes to the long-term performance of the carpet and minimizes potential issues such as fraying or seam splitting.

In contrast, while other methods like hot-melt adhesive or sealing tape might have some applications, they do not offer the same level of effectiveness or adaptability as the specified adhesives. Standard glue generally lacks the specific properties needed for carpet seams, which may lead to failure in adhesion during regular use. Thus, acrylic, latex, or thermoplastic adhesive stands out as the best practice for sealing seams in stretch-in carpet installations.
