Must use - Bset primer out there.

4 gallons for price of 2. Same stuff, not off brand. Comes in 4 separate gallons so easy to handle and store if you dont need all 4 right away. Locks in old plaster and drywall to keep from absorbing moisture. Primes walls for interior paint. Bye-bye mold on outside walls for good. Goes on with bluish tint so you can tell where you have coated but dries completely cleae so won't mess with your color coat. Does so much more than your basic primer by sealing out moisture.
