What is the difference between Acrylic Finishes and Portland cement based Stucco Color Coat?
ยป Acrylic finishes utilize paint technology with aggregates added that can be trowel or spray applied with the appropriate equipment. Acrylic finishes can be applied over portland cement base substrates and EIF Systems using an approved grade. Stucco Color Coat is a natural cement-based material; acrylic finish is a synthetic man-made coating. Stucco cures to a hardened state while acrylics dry to a hardened state. Acrylics dry from the outside in and can be sensitive to environmental conditions. Air circulation is as important for drying as the temperature, especially in humid conditions. Cement stucco finish “cures” as opposed to drying. Cement finish coats are a nominal 1/8 inch thick and have the ability to fill small imperfections in the base coat. Acrylic finishes have very little ability to compensate for surface irregularities. For acrylics or cement finish, the portland cement plaster base coat must be cured before applying the finish, but a longer cure time is beneficial. It
