I first planed and sanded the edges of the door assembly removing any rough areas making it good for sealing.
It was then a matter of rebating to allow for the four hinges to be attached. Again the router was used here and once set up correctly
As with door 1 I applied three coats of diluted PVA to seal the MDF. I little easier this time as drying time between coats was a lot less than before in the colder temperature. This meant I could easily get two coats on per day.
