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.

    This primer is thick in texture, it covers yellow stain on ceiling and wall from leak perfectly, also kills mold. No sanding, and no prep work is done, just used a fan to blow the ceiling completely dry. Two coats applied by using a 4" roller and a 1" foam brush for corners. This primer alone is good enough for me.

    Painting over douglas fir siding that had not been painted in 20 years this primer saved a lot of money caused a lot sweat but its worth it looking at the finished product. The primer sealed the wood and helped paint suckin in to the untreated wood. Will last a long time and look good for ever. Great Product.

    The primer worked very well. There was no bleed when painting over knots which were on my boards. After applying a second coat there was no bleed through with the finish coat. There was also good adhesion and fair coverage on bear metal. In summary the performance was very good.

    Water stains and tannins bleed right through
    Bought this to finish up priming the walls and some wood shelves in my garage. Both had some water damage so I was careful about buying primer that would cover it. I had started the project with Ben Moore’s INSL-X Prime Lock Plus, which covered the stains perfectly, but I ran out and bought some of this Zinsser stuff instead since I live near Home Depot. What a mistake! Every water stain and tannin bled right through. What a waste of a beautiful afternoon. Wish I could get a refund. Looks like I’ll be buying more INSL-X and redoing the job next weekend.

    That's odd, Jen! Rust-Oleum Zinsser Cover Stain Oil-Based Primer is great for blocking both water stains and tannin bleed. Since this is a primer, it will trap most stains in the film to prevent bleed through with the topcoat.

      go-to
      Ive used several different primers over the years but always come back to this one. It sticks to almost anything and you can use anything with it. It hides stains and tanins fron wood. I used a latex primer to prime oak cabinets, but was dealing with tanin bleed through. I used this over the latex primer and it completely hid the tanins in one coat.

        Primer when sprayed dries pretty smooth with light sanding required for finish applications. I sprayed some stained cabinets & works perfect.

        Was able to cover 30+ years of nicotine staining and odors. Needed more than what was recommended coverage by the manufacturer though. Still not a concern - great product.
