Don't know any reason it wouldn't work well on a ceiling. It has great pressure and nice even flow. The only thing I would be careful of is tipping the paint container back to far so the paint can't be picked up by the intake.
It depends. You should thin it some if its very thick poly. I have not used this with poly so not sure. If you do a poly project let us all know how it worked for you okay?
@@rowdydawgshonestreviews wood preservatives, clear sealer, polyurethane, and stain do not need to be diluted per the instruction manual. I used Minwax premium water based polycrylic and it worked great.
@@joarby well thanks for your comment. Sorry you didn’t like my review. Not an expert painter just showing the product. For a rookie DIYer it works good for me.
@@KARINACARDENAS-t6b THANK YOU!! I was just trying to show how it works not an expert to say the least but I do lots of painting with this thing and it does the job. May not be expert technique but oit works for me.
