I am a newbie woodworker, but have been doing a lot of reading/research on this great hobby and this is my first post here.
I am working on a shelving unit, using Poplar. I have made all my cuts/dados/etc and I am in the final stage of putting a finish on my project. The project is 6ftx4ft and will have 8 shelves, to include a ¼” backing. The shelf will be used to hold my Blu-ray/DVD collection. I am in the final stage of putting a finish on this project. The project has NOT been assembled yet, because I think it would be easier to apply the finish, then assemble it.
I have read/watched a lot about the mystery and confusing topic of finishing. I have purchased the e-book “Wood Finishing 101” by Bob Flexner. It has some good info, and step by steps, but does not really help me solve the issue I am having. I am thinking about purchasing Charles Neil book “Finishing, Simply Put…No Chemistry Degree Required”. Anybody own and recommend this book for newbies like me???
On to my problem. I have a 1×6x6 piece of scrap poplar that I am using to test my finish. I have routed some dados in the piece to separate my tests areas (see picture). The problem I am having is that some parts of the piece are showing little speckles of blotching (see arrows). I know that poplar is a wood that tends to blotch, that is why I added Zinssers Bulls Eye Seal Coat (dewaxed Shellac).
The first section I added 2 coats of undiluted shellac. I waited for 2 hrs. before I sanded very light with 220gt paper before I added the 2nd coat. I did use an orbit sander, but barley put pressure on it. Should I have hand sanded it????
After the coat was dried for about a day I applied (wiped on) a coat of Minwax Gel Stain Mahogany 605. I notice in some parts of the piece there were speckles of some blotching (see picture).
The 2nd section of my test piece was diluted shellac (using 1 part denatured alcohol/1 part shellac, properly measure), using the application process like the first section. Again there was that speckled blotching.
What am I doing wrong, and what can I do to prevent this? Is this just the nature of the wood, and I am going to have to deal with it? I really want a nice looking finish for my project, and do not want a half-butt crack looking one.
I did not skip sanding grits and did progress with the size, starting with:
Please help!! I want an even application of the stain across my surfaces. I plan on using Minwax Fast-Drying Polyurethane Clear Semi-Gloss for the last coat. I am in the military and move quite often, and would like to protect the project from different environments (i.e. humid areas, dry environments) I may be stationed at.
