I do a lot of slab work for bar,kitchen,vanity & cabinet tops etc.
I usually finish the work with 2 pack polly, because it is chemical & abrasion resistant, long lasting & fairly natural looking.
Feature grade blackbutt is popular with many customers they seem to like the black gum veins present.
When lacquering this type of timber, the black lines will never fill level with the surface. It is so very time consuming to fill these with any kind of stopping. I have tried ebony timber-mate, west system epoxy with black oxide, & very recently a water based clear fill product called acquacoat. Has anyone found a method for this particular situation that they are happy with?
