AFM SafeSeal was designed to block chemical VOC emissions, not organic mold and mildew odors.Cinder blocks are usually very porous and should be sealed with our GBS Clear Penetrating Concrete Sealer. Apply with 3-4 applications and the sealer will soak deep into the concrete block and chemically bond inside. This will fill the microscopic pores and permanently prevent water intrusion from outside in and from inside out. This is warranted for 15 years. Once sealed, it will be very difficult for mold and mildew to grow inside the block or window sills.Another option is to consider applying two coats of our Caliwel Mold Inhibiting paint which kills mold and mildew and prevents its growth for 6 years or more.
