How much area does 5 gal of elastomeric paint cover?

I want to paint my kitchen table and chairs. The table is an old one with what looks like plastic laminate on it. How would I paint that and with what type of paint? The chairs are wood, would I just use any wood paint. Thanks for the help.

So here is my problem. I tried staining my new fiberglass door, using gel stain, in cold wind. The result was horribly blotched. After a lot of searching, I decided to remove the stain and try again fresh. I used CitriStrip spray, plastic bristle brushes, a lot of elbow grease,

I’ve recently tried to paint my bathroom with a very bright color. I used 2 coats of paint and yet the result was an uneven tone, some parts of the painted wall are darker than the others. How do I fix this problem? I did use a white primer before
