Modern acrylic binders for water‐based exterior wood coatings should give films which are tack‐free, hard and blocking resistant and at the same time very flexible to guarantee a long service life. This study shows that multiphase acrylic emulsions with controlled particle morphology give a means to overcome these contradictory requirements. Binder parameters such as polarity, particle size and surface functionality as well as the type and quantity of surfactants used in the process also have a strong influence on fundamental wood coating properties, such as water protection, blushing resistance, viscosity, wet adhesion and durability.
