Poor adhesion
I painted my house about 8 years ago I used Zinsser Cover Stain oil base primer, premium caulk and a premium latex top coat, the house had new factory primed hardboard siding, the trim and fascia are wood. The preparation consisted of removing all loose paint by scraping and sanding. The house was power washed and tested for moisture content before applying primer. The gable and eve fascia began peeling within a couple of years now 8 years later most of the finish has peeled off exposing bare wood and a small areas of paint has peeled off of the siding. Maybe the primer was old, I had Home Depot machine shake all three 5 gallon and a 1 gallon cans then they were hand mixed prior to application by airless sprayer so the mixing should not have been a problem with adhesion failure. I feel sure that power washing the now house would take a the finishoff of the siding. I expected the paint to last longer than 8 years. Now the preparation and painting the 3 gables, eves and the window fascia needs to be prepared, primed and painted again. The painting should have lasted 15 years and it would have had the pruner not failed. I am quite disappointed in the performance of the primer, a huge waste on my time and money.

Thank you for sharing your experience with Rust-Oleum Zinsser Cover Stain Oil-Based Primer. Please keep in mind, the life of a coating is dependent on several factors, including the condition of the surface and the elements it is exposed to. With a primer the topcoat used can also factor in. With this primer, with proper surface prep and application, it will last for several years.

    Would not lay flat
    I used Cover Stain to prime painted smooth plaster walls in a small 1/2 bathroom and it left a very pronounced rough stipple. I applied the primer quickly and yet it did not flatten out. I had to use a palm sander to reduce the stipple. I used Cover Stain years ago on newly plastered walls and it worked fine. Also, the spray can version worked wonderful on finish wood. I like oil based Cover Stain Primer because you can sand it smooth before finish coat. However, this time, the primer was too thick to apply smoothly, and Zinsser states you should not thin Cover Stain Primer. I am very disappointed because I can still see the some of the stipple marks left by the primer.

    If a texture is visible on the previously smooth surface after applying our Zinsser Cover Stain, the primer is being applied too heavily, most likely using a long nap roller cover. Smooth surfaces will prime best using a 1/4-3/8" nap roller cover, taking care to apply a thin, even coat of primer. - Rust-Oleum Product Support 2 Rustoleum

      This is the perfect primer/sealer. It dries faster than water based, but not too fast, like Zinnser BIN, which is alcohol based. Zinnser makes good stuff.

      I was disappointed the employee did not know how to tent primer the best he could do was tint it a very pale green and I needed a very dark germ or black. I also had to wait for 45 minutes for some one to help me.

      Oh no, this is not what we like to hear. Zinsser Cover Stain Oil Based Primer provides excellent penetration and flexibility and has excellent adhesion and stain blocking properties. It cannot be thinned as this would affect stain blocking properties. Give us a call at 888-855-1774 so we can hear more about your application and try to make things right.

        I have tried many other stain blockers/ primers and keep returning to Zinzer oil based primer. I find that it covers better and lays smoother than others. Since it is oil based it doesn't raise the grain of wood the way that latex primer tends to do which saves time and more importantly money.
