Questions: Can I add oil stains to epoxy?
Answer: Thank you for your inquiry. A better resin system to use for your
application of filling or potting knot holes for your maple flooring is the
MAX CLEAR GRADE, also sold as MAX CLR resin system. This resin is a
low viscosity resin system (thin in consistency) and it is optically clear
that will receive the tint you wish to add. The low viscosity allows for
the mixed resin to penetrate the wood porosity and allows for air
bubble release during filling of the wood voids. Here is the link for your
I am not too familiar with the W.D. Lockwood Dyes, however, after
visiting their website, I noted that there is an alcohol/acetone and oil-
based dye systems they sell. These are compatible with epoxy resins;
do not use water-based as it will not properly disperse. You can also
try the wood stains from Cabot that our lab has tested, see
attached pictures. Cabot Stains can be purchased at Lowe’s or Home
Depot in varying color shades.
To prepare the epoxy/stain compound, dispense the
appropriate amount of resin component or PART A and to it slowly add
the stain additive until the desired saturation is achieved. Make sure
the stain and the resin are well mixed and then set aside for several
hours to allow any entrapped air bubbles to degas from the blend.
Prepare the wood knot to be potted ensuring it is dry and free from
dirt. Try to remove any old coating if the wood has been
coated before. Use a vacuum to clean out any debris from the void
Mix a small amount of the tinted PART A and to it, mix 50 parts curing
agent or PART B and mix gently to avoid air bubble entrapment. Apply
the mixture using a brush and allow the resin to penetrate the wood
porosity and allow it to set for 2 to 3 hours. This will seal the wood and
prevent further absorption and bubble outgassing. Once set, mix
another batch or the tinted MAX CLEAR epoxy and then fill the void
flush and allow to cure for 24 to 36 hours. It will cure to a hard, glossy
finish that can be sanded flush and effectively fill the knothole.
Here is a video demonstration of how pigments are incorporated
with an epoxy resin, which you can use the same addition technique
for stains as well.
