This is now our go to primer for many uses. Its coverage is amazing, its adhesion is excellent, its dry time is very fast, and best of all, it is INEXPENSIVE. Add that it is latex based for easy cleanup, and that it primes nearly any surface effectively, and you have our go-to product for almost all priming situations. The only situation we have seen it struggle on at all is bare, non pressure treated wood- we feel that we have seen some bleed through of tannins / oils. In contrast, however, we have recently treated a number of oily, dirty cinder block basement walls with no prep whatsoever, and the coverage has been so flawless that we top coated with Valspar Stainblocking Primer only because we promised the client that we would!
