Finishing a Dining Table Top10/1
Hello Professional Finishers:
I am a professional cabinetmaker but a finisher only when I need to be, like now. I have built a dining table with a sketch face veneer top. I need a clear finish that is water based, durable, water resistant, hopefully self sealing, and that has something of an amber tone to mimic nitro lacquer.
If it could build and cure, that would be perfect. Pre-cat? Post-cat?
Is this asking too much, or have I been out of the finishing loop too long?
I'm using Emtech 8000CV conversion varnish on a cabinet job right now. It's available online from Target Coatings. It has a slight amber tone, is water based, and you can add a catalyst to further harden it, or top coat with their 9000 superclear poly. I haven't used it for a tabletop yet, but it has worked well for me on kitchen and bath cabinetry. The next step up is the 2k poly finishes but I've no experience with them.
My experience with the WB coatings that have the amber look is that over the years the amber color can actually take on a pinkish hue. This has happened with a few different types from different manufacturers.
The best, most consistent answer I have found is to use a clear WB and to add a few drops of Amber trans tint dye to the seal coats and then to clear over with the final coat. Spraying any WB over clear,unstained wood has never satisfied me when trying to mimic solvent coatings.
If you are staining the wood, adding a little yellow and red can adjust the tone as well to help get the look you are going for. This is an approach I have used when matching aged stained wood with new wood finished with WB products.
I use the Target 8000 too although never on table tops that said the local micro brewery finished all their table tops with 5 coats.. Some 2.5 years later and lots of use they still look great
Thank you for your responses.
I don't know much about finish material composition, but isn't adding a couple of drops of amber tint what the finish manufacturers do? If it turns pinkish over time, I imagine the effect is gradual, and may only be noticed when compared to some kind of control sample, unless the pink is "in your face".
The last time I used clear water-based lacquer by itself, it was as though I had wrapped the project in Saran wrap; a clear plastic coating that served to protect, but did not enhance the appearance of the project at all, especially given that the project was walnut.
I was then informed of the use of stains and sealers to achieve that "old lacquer look". I was hoping to find a single product that might produce that effect. This serves to underscore my lack of finishing expertise.
To JohnB and Nick:
Finishers I have used in the past have said that they liked the Target line of coatings. My personal experience goes back to the infancy of water-based finishes, and having been unhappy with the results, continued to use the solvent based materials until reduced availability, the insistence of my insurance company that I use non-combustible finishes, and the retiring of the finishers I used have brought me to my present state.
The finishers liked that the owner of the company, a chemist, was available to answer questions, and they seemed to like the product performance. Perhaps I will give it a try.
Thanks to all who have responded; it is what makes the Woodweb a great resource.
