What finish to use on dyed veneer?9/19
I have to do a full filled finish on a light grey dyed veneer. I was told that the finish should not contain an acid because it will react with the dye and cause it to change color. The veneer is made by Tabu, any suggestions would be appreciated. I want to use a polyester sealer to get the grain filled, but don't know if it will cause a problem.
We finish a ton of grey tabu veneer. Let me say this, no matter what you put on it, it will change color. It will still be grey, but not the same exact grey that it is when not finished. Tabu veneers are also NOT light fast and will shift colors once installed very quickly. Ive seen panels shift colors inconsistently as well (half of one panel shifts and then maybe a panel 3 panels over shifts)
Read the PDF file at 'Mundy Veneer' for finishing. They suggests, as above, ICA exterior Waterborne acrylic coating.
May want to ask other manufacturers:
The best bet is an acrylic system. Milesi has an acrylic sealer that contains a UV additive. there is also a UV additive for the acrylic topcoats. As far as a full fill, as you know acrylics are not the highest building, so this is the trade off. Polyester will give you the build, but the yellowing will shift you color over time.
There are also self sealing "natural effect" 5 sheen products that can reduce the color shift due to the wetting action of the finish on the surface of the wood - available in water and solvent base. The UV additive can be used in the solvent base version. They are a 5 sheen and unfortunately have a very low build.
Several options, but unfortunately not 1 that fills all of you needs.
Good to hear that you are back in the biz.
