IICRC WRT Carpet, Cushion and Floor Covering Restoration

Question 1

How should carpet and cushion exposed to Category 3 water generally be handled?

Accepted Answer

Removed and discarded

Answer

Porous materials like carpet and cushion that are contaminated by Category 3 water cannot be adequately cleaned, so they are generally removed and discarded.

Question 2

What is the main purpose of "floating" carpet during drying?

Accepted Answer

To create an air space under the carpet so airflow can dry the backing and subfloor

Answer

Floating carpet means releasing it from the tack strip and supporting it on air flow so the carpet, cushion, and subfloor can dry. Special equipment such as a floating tool or air injection helps.

Question 3

Hardwood floors that absorb moisture from beneath typically show which deformation first?

Accepted Answer

Cupping

Answer

When the underside of a board has higher moisture content than the top, the edges rise and the board cups. Drying should be controlled to avoid further damage such as splitting.

Question 4

Why is water extraction typically done before evaporative drying on wet carpet?

Accepted Answer

Extraction removes much more water per hour than evaporation

Answer

Mechanical extraction removes bulk water far faster than evaporation can. Removing it first reduces the drying load and the time it takes to reach the drying goal.

Question 5

Wet carpet cushion that has been contaminated by Category 2 water is usually:

Accepted Answer

Removed and replaced

Answer

Cushion absorbs and holds contaminants and is inexpensive to replace, so it is usually removed and replaced when exposed to Category 2 or 3 water.
