IMPORTANT: It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Check with all local, state and federal regulations prior to using or working or using this product. Fix the source of any moisture problems prior to remediation. Do not attempt to salvage damaged or structurally unsound building materials.

SURFACE PREPARATION
For applications that have existing wet, slimy, heavy soiled, gross filth, overgrowth, or loose material on the substrate a pre-cleaning step is required. Physically or mechanically remove gross filth, heavy soil, overgrowth or loose material including dirt, grease and oily films before application and ensure the substrate is free of slime or excessive moisture to ensure long-term adhesion and product performance particularly on exterior surfaces. If mold or mildew needs to be removed prior to application, remove with a mildew remover that is EPA registered and let dry. Wear eye, skin, and NIOSH approved respiratory protection. Patch surface irregularities with appropriate patching compounds.
APPLICATION
Mold Blocking Primer is a ready to use product. Use at room temperature (70°F) in a well ventilated area – do not use in high humidity conditions. Shake can vigorously until ball inside can rattles. Turn upside down and continue shaking for one minute. If ball does not rattle, do not strike can. Contact Rust-Oleum. Shake often during use. Hold can upright 10-12” from surface and spray with short ‘dusting’ strokes. Keep the can the same distance from the surface. Keep the can in motion while spraying. If valve clogs, twist and pull off spray tip and rinse it in a solvent such as mineral spirits. Do not stick pin or other object into the stem. Do not use near open flame.
Mold, Mildew, Fungi, and Odor Causing Bacteria Control: Mold Blocking Primer will reduce the growth of all mold, mildew and fungal organisms for up to 7 days. Apply Mold Blocking Primer generously and uniformly, ensuring that the surface is completely coated. Allow to dry. For optimal protection, apply a topcoat that prevents mold & mildew on the paint film within 7 days of application.
NOTE: Do not topcoat with solvent based lacquers.
