Water-based finishes stick very well to old finish if there are no contaminants on the surface. Clean the area with a low suds cleaner. If you are close to bare wood there is probably no finish left on the surface, but some may have soaked into the fibers. I would still use a sealer and al least one coat of finish. The two part finishes are more resistant to wear, but single part ones will protect for years. You will not get a color match, but if the finish sticks on a trial are and doesn't peel off with the packing tape test in which you cut into the finish with a razor blade scratch and then press the tape hard, then pull it off.
Thanks for responding!
So I need to clean the area first with something like Basic Coatings Squeaky?
That's easy enough. I can also do the tape test as you recommended. I remember reading about that a few years ago.
What are your opinions on using a product that is beyond it's shelf life? I have an almost full gallon of Emulsion Pro and Another 3/4 full gallon of Hydroline Plus. I know the catalyzer is probably garbage, but it sure would be nice to be able to use up what I have on hand, but they're both well over 2 years old now. I believe the shelf life was 1 year.
I was going to try strain some and try it on some scraps to see if it still looked like it was good, but I'm also afraid of it failing down the road.
If I need to buy fresh stuff I'll bite the bullet but this stuff is sitting there so I figured it can't hurt to ask.
