Extreme Flooring Acrobatics. An interesting activity, to say the least. Its usefulness, however, is not to be belittled. Allow me to elaborate.
EFA most often begins with a mistake. Someone locks themselves out of an entrance that is now inaccessible from any other area in the house; someone forgets their car keys on a counter top that is now surrounded by freshly finished floor; or someone forgot to turn off a light. In these cases, it is very helpful to have someone around who is EFA certified.
Some feats are easier than others. In one case, I had to climb along the edge of a sliding glass door, jump up to reach a ledge of a window above the door, slide myself over, and drop down onto a mantel to retrieve a pair of glasses. Other instances can be solved by simply having a co-worker anchor himself against a wall (or your foot), hold on to you and act as a counter-balance as you reach out to fill in a missed spot or pick something out of the finish.
Whatever your situation, EFA certified individuals can make the unfathomable possible, the inconceivable a reality. EFA certification is a must for flooring buiseness of all sizes and expertises. Contact your local EFA official for more information and training.
