The present invention relates to a method of making a consolidated cellulosic article. A cellulosic mat is provided. A latex-free, foamed sealer comprising a thermosetting resin is applied to the mat. The foam covered mat is then positioned between upper and lower platens of a press. The foam covered mat is then positioned between upper and lower platens of a press. The foam covered cellulosic mat is compressed between the upper and lower platens using heat and pressure. The foam sealer is de-forming during compression, forming a consolidated article having a sealer coat. The present invention also relates to a door having at least one door facing with the sealer coat.
