Colouring Kit for Fill-It epoxy filler Instructions
The Fill-It parts A and B should be mixed together as the product instructions recommend. Then, as each pigment is added, colour will develop with mixing. Continue mixing until no further colour change is seen with continued mixing. Only then add another colour pigment.
Add a small amount of dry white pigment, perhaps a tablespoon or two for a mixed quart. Next, a small amount of red or yellow may be added to approximate the red-yellow balance. Then add a little black to darken to the desired colour. Then, try a little more red or yellow if needed. Should the mix be too dark, add some more white to lighten the mix. The total amount of white pigment needed may be comparable to or much more than the total amount of all the other tinting pigments, as a VERY rough guide. Very dark woods will need less white, and will usually have more red than yellow.
