First coat of the base coat namely the scratch coat 3/8’’ minimum must be scarified and allowed to set before the second coat brown coat 3/8’’ minimum is applied. Then immediately double back, without cross hatching the first layer, using the material of the same proportion to build proper base coat thickness.
