After the 50's and into the early 60's wood flooring saw a decrease in demand. This was partly due to the introduction of plywood sub-flooring and a shift in concrete-slab foundation. Hardwood is much harder to install on concrete-slab because it needs to have a moisture barrier in between. Installing hardwood is also much more labor intensive and other flooring could be installed much easier on the new plywood sub-floors. This increased the popularity of carpet flooring. All of this caused the wood flooring industry to crash in the mid-1960s.
In the 1980s wood flooring started to get a renewed awareness. Wood flooring manufacturers started introducing new prefinished hardwood flooring. Much more stains and finishes were introduced along with water-based urethane which made finishing much quicker. This gave consumers a lot more options to choose from. Some of these options include traditional hardwood, prefinished, engineered hardwood, solid floors, floating floors, nail-down and glue-down hardwood. North American hardwoods and exotic hardwoods from other countries around the world were also available. Thus the current re-emergence of hardwood flooring that we see today.
