Hi all, new member here. Home woodworker or at least pretending to be :). I love building things and each project gets just a little better.
Right now I am building a farmhouse style desk with bookcase. Base is painted and poly,d with water based poly. Learned about grain raise but that is fixed and done!
Top is made of 1×6 pine. Stained already. To make life easier since I am oil based on the top I was going to spray on with my sprayer. I was in Home Depot and saw aerosol cans and decided that seemed great as no cleanup. Setup my spray tent outside and sprayed on a coat. It seemed SO light it was almost not there after four hours so I sprayed on another coat. I was not thrilled abojt how thin it was going on as I could foresee this needing a lot of coats to build up anything. So I moved them inside where I could setup my horses and put on poly with a foam brush. Watched videos on technique and put on 2 coats sanding 220 between the spray and first coat and the second brushed on coat. These went on way thicker and I certainly have a nice build up of finish. Also kind of impressed with myself lol as if is very smooth.
My question is how to know if I should do a 3rd coat of brush on. I had some spray on there, so it had material. I just dont know if it was enough to do anything. I certainly have a nice finish on now. If it wasnt a desk I would definetly stop. But as a desk I want to ensure I have good protection. But I dont want to put on too much where it gets plasticy or doesnt bond right.
