This method of carpet installation reduces the life of the carpeting by 33%.

The method of direct glue installation significantly impacts the life of carpeting due to the nature of how the carpets are adhered to the subfloor. In this installation technique, a strong adhesive is applied directly to the flooring surface, which can lead to a variety of issues over time.

Firstly, the adhesive creates a rigid bond that does not allow for the natural expansion and contraction of the carpet fibers. This restriction can result in stress on the fibers, which may lead to premature wear and fraying. Additionally, if moisture gets trapped underneath the carpet, which can happen with direct glue installation, it poses a risk of mold growth and other damage. These factors combine to reduce the expected lifespan of the carpeting by approximately one-third compared to other installation methods that may be more forgiving, such as tackless or double stick.

In contrast to direct glue, methods like tackless installation utilize a strip with tacks that hold the carpet in place without creating a rigid bond, allowing for more movement and flexibility, which typically prolongs the life of the carpet.
