Since MDF mouldings are sensitive to humidity and temperature fluctuations, it’s important that the room they’re installed in has a good ventilation system. After installation, seal the top and bottom of the mouldings with an appropriate product.
Room temperature and relative humidity directly affect MDF. Materials can contract or expand accordingly. Allow the MDF to acclimate to the air and ambient heat for 48 to 72 hours before installation. Avoid long-term storage in the basement or an unheated garage.
