VOC & Sustainability

Be sure that temperatures of the air, floor and finish are all between 70°F-80°F. As the finish is applied, it will quickly reach the temperature of the floor. A warmer temperature can cause the finish to flash dry and not flow out properly. A cooler temperature can raise the viscosity of the finish, which could result in thicker coats, slower dry times, delayed curing and even wrinkling. High humidity can slow the evaporation rate of the solvents, which will extend dry times. Allow for longer dry times when applying in high humidity. Also, never apply finish when the ambient temperature and dew point are within 5° of each other. This could allow water to condense on the floor, contaminating the finish.

Low-VOC finish should always be applied at a minimum of 500 square feet per gallon. If the coverage rate is below that (i.e. 400 square feet per gallon), then the finish is being applied too heavily. This will extend dry times. For best results, use a heavyweight T-bar to apply. It’s a good idea to calculate the square footage of the entire floor and then place a new pail of finish every 2,500 feet. As you reach each new pail during application, you should have emptied the previous one.

It is important to eliminate outside air and turn off HVAC systems during application and until the film has become tack free (usually about 8 hours). Then, allow fresh airflow on the floor to help with the curing process by removing the solvents that blanket the film. Introducing airflow to a wet film will cause it to skin over and trap the solvents underneath, significantly extending dry times. Only allow air back on the floor once the film has become tack free.

Low-VOC products are high in solids. This is great for build, protection and gloss, but it also requires 24 hours before it can be top coated. Drying overnight may not be adequate in some situations, so allow for these products to dry for a full 24 hours before applying another coat.
