Working with wenge veneer, which has long deep pores. For testing, tinted batches of Unibond with Homestead Finishing's liquid Transtint and powdered analyline Transfast 100% water concentration. Fourteen drops of either in 100 grams resin seemed to give maximum tinting of the resin, and the dried Unibond looked very close to the desired color.
However, on sanding the veneer 80, 150, 220 the abraded Unibond was MUCH lighter again. Same result on a dried piece of Unibond. Tried scraping but the Unibond still much lighter than the wenge. Did find that sanding the previously abraded piece of Unibond with 1500 grit paper left the surface much darker, almost as dark as the unsanded Unibond.
Buying and using Unibond Blocker would be a solution, if it prevented all bleedthrough, but I've grown to like uniform bleedthrough spotting, to show that the bond is likely very good.
Has anyone found success with a different tinting method that remains when the glossy surface of the dried Unibond is sanded off? Thanks.
