Always use an approved EIFS Sealant when caulking EIFS.
A low modulus-approved sealant is used as a weather sealant in order to seal terminations. This sealant is used in order to have the best paint-ability where painting is required. A durable watertight, flexible seal will form and the adhesion to EIFS and other porous surfaces is reflected in an outstanding curb appeal for your building.
Master Wall or any premium primer will be acceptable in order to ensure proper adhesion to the EIFS and other porous surfaces such as masonry surfaces. Metal and non-porous surfaces must be clean and rust-free. You may use a solvent to clean it with, which is available at most building supply houses.
