To prevent issues where parties in the industry might focus on a certain time to dry a wood floor, all readings are reported as a ratio compared to the plywood control cell. So for example, if the plywood control took a certain time to dry, and another material took 2.0 times the control, it could be said that it would take twice as long to dry vs. bare plywood. Expressed in drying time, if it took 24 hours to completely dry bare plywood using a certain drying system, a material that had a factor of 2.0 would take 48 hours to dry.
We considered an area to be dry when the readings in that area (including all layers) were within four percentage points of the dry standard for that floor assembly.
Time to dry based on type of wood
When analyzing the type of wood and how long it took to dry compared to the plywood control, results show that:
- True hardwood flooring systems dry at virtually the same rate as plywood
- Other wood flooring systems dry faster than carpet and pad over plywood
- Of the wood flooring systems tested, bamboo and low quality engineered wood were the slowest drying
