nakanuri 中塗り

Also called chūgomi 中込, nakazuke or chūzuke 中付. A middle layer of plaster applied between the base and finish coats of a plastered wall. If there are more than three layers of plaster, it is the one directly beneath the finish coat. Its top surface is smoothed so that the final top coat can be laid without flaws. The term is also applied to a surface that receives several coats of plaster.
