This was thick, making it easy to paint on the celling. It took 2 coats to cover the water stain i was working on but it did cover. One thing to note is that it is VERY bright, blue toned, white in color. i use white celling paint and or was much brighter.

Pricey but worth it

We are using this to seal up rough cut lumber and logs used in the construction of a cord wood home. This product is the best I have tried (and have tried many), after one heavy coat it completely seals in and primes extremely rough cut wood, its so smooth after one coat I can hardly believe it. Pricey but worth it.

Does what it says.

I ripped up my dining room carpeting and laid a thin coat across the OSB that was beneath it. I plan on painting the OSB board and sealing it until I can either afford linoleum or laminate flooring. This product covered up any stains/odor that was present. The only downside is the smell of the product itself. It's been about 2 weeks and the odor is still very present. Overall I'm very happy as it did everything it said it would.
