Applying Finish to Your Door

To give your door a lasting and beautiful finish once your stain has dried completely you will apply three coats of Wattyl Estapol Exterior Clear (or suitable alternative) sanding lightly between coats. Pay special attention to the corners of the doors and remove drips as they form. Apply in the same order as the stain; raised panels then rails finishing with the stiles.


The end result is a beautifully stained door that if you didn't know better you would be sure that is is made out of wood.
