Which carpet type typically requires the most effort to extract moisture from?

The type of carpet that typically requires the most effort to extract moisture from is the direct glue installation nylon carpet. This is largely due to its construction and the manner in which it is installed. Direct glue installations mean the carpet is adhered directly to the subfloor with an adhesive, which may trap water between the carpet and the subfloor. This situation can create a scenario where moisture is not only retained in the carpet fibers but also in the adhesive and flooring beneath, making extraction more complex and labor-intensive.

In addition to the adhesive component, the density and pile of the nylon carpet can also influence moisture retention. Nylon carpets are generally sturdy and may have tighter loops or denser fibers that hold onto water more stubbornly than other carpet types.

Other carpet types, such as cut-pile polypropylene, loop-pile nylon, and Berber carpets, may allow for easier moisture extraction due to their construction characteristics or installation methods. For instance, cut-pile polypropylene may have a more open structure facilitating faster evaporation, and Berber carpets, although they can retain moisture, often have loops that can drain better than glued-down constructions. This makes direct glue installation nylon the most challenging carpet type for moisture extraction.
