I think my hard surface floor's appearance should be improved, but I'm concerned about the price. What should I do?

Consider the cost of non-action. Any finish will enhance the appearance of your floor in addition to providing protection. While refinishing your hard floor bears a cost, replacement of the floor due to neglect bears a much higher cost.

Will the application of urethane disrupt my business?

The initial application process will require stripping any existing coatings and applying urethane coating plus drying time. This process can be done after hours and will require only daily cleaning for the life of the finish, averaging two years. Because there is no buffing or recoating for that time period, there will be no other disruptions. The reapplication process will not require further stripping.

What is an epidemic vs a pandemic?

According to the World Health Organization (WHO), “a pandemic is a worldwide spread of a new disease.” Before a disease is declared as a pandemic, it has to exceed a few other levels, according to the Centers for Disease Control and Prevention (CDC):

Sporadic:

When a disease occurs infrequently and irregularly.

Endemic:

A constant presence and/or usual prevalence of a disease or infection within a geographic area.

Epidemic:

A sudden increase in the number of cases of a disease — more than what's typically expected for the population in that area.

Pandemic:

An epidemic that has spread over several countries or continents, affecting a large number of people.
