Topic tags/keywords: soap making lye finish finishing

I have made a soap mold/soap slicing box for my wife’s soap making hobby, but I don’t know if my finish will react with the lye. The choices I have right now are salad bowl finish, paste wax, or good old polyurethane. Are any or all of these okay to use in this case? The mold box holds a silicone mold, so the soap contacting the wood is only long enough to slice the brick into bars. Thanks for looking and for any advice you can offer.

Don’t know for sure but my gut tells me polyurethane. Lye is a strong base and I know that polyurethane enamel paint holds up amazingly well to acids, maybe it’ll do the same for bases.

Thank you, ShadowRider. I had an offline suggestion for polyacrylic for the same reason. Thanks for confirming that.

Don’t make it out of wood. Make it out of PVC lumber.

Have your say...
