So I’ve dyed my table legs with transtint. On the sample boards I’ve made, when I wipe on the Enduro var finish, I tend to get the dye to run a bit. Is it OK to use the non wax shellac can spray before wiping the Enduro?I’ve never used a can spray. How much spray to actually out on?

It absolutely is (and recommended by many). Transtint will dissolve in water and the moisture in the Enduro var is re-dissolving it and causing the streaks. The shellac will seal it form the moisture…..I suggest de waxed shellac (Seal Coat) since the wax can cause problems sometimes with waterborne top coats.

Transtint will also redissolve in alcohol which is the medium in shellac. What I do is use a oil base poly cut to 50% with thinner as a coat over the dyed wood to seal the dye. Then finish with what ever.

Good advice
If you have the means to spray it with shellac then you won’t have the lift you can have by brushing it on. If you don’t have a spray gun Harbor freight sells guns that work fine for a low cost,of course that means you need a compresser that will deliver enough air volume to spray with.Just like you did before first practice spraying say water on some cardboard or on an unimportant piece of plywood then try the Shellac on a sample piece of wood.

Good point, it will dissolve in alcohol as well, the shellac needs to be sprayed.

Great. Thank youyou. I purchased a can of the zinnser (sp) areasol so will try that. Assume a light coat will do?

You’re just trying to seal it from the water, so the light coat (but it has to be 100% coated) should do.
