When replacing a damaged section of tufted glue-down carpet, where should seam sealer be applied?

Seam sealer should be applied at each seam edge and applied to the assembled wet area to ensure a strong bond between the carpet pieces. This method is crucial for maintaining the integrity of the seam, preventing delamination, and ensuring that moisture does not penetrate the seam area, which could lead to future damage such as mold growth or separation of the layers.

Applying seam sealer only at the seams would not provide adequate protection along the entire edge of the carpet where it meets the newly installed section. Similarly, sealing across the entire patch area could lead to unnecessary waste of sealer and may not adhere appropriately to the substrate since seam sealing is specifically intended for joints. Applying seam sealer only on the back of the carpet piece would limit its effectiveness, as it is essential to secure the edges where the carpets meet to resist fraying and separation over time. By focusing on each seam edge with wet assembly, it ensures a tight and reliable join that withstands wear and movement.
