To obtain the best results, you will need to maintain a wet edge between each section of the door.
Therefore if you paint the panels in the numerical order, this will give you the shortest time that an edge is left, thus stopping it from drying out thus avoiding an uneven build up of two coats of paint.
Make sure the surfaces are clean and free from grease
*First start by painting the edges of the door avoiding excess paint being brushed onto the vertical stiles.
*Then start on the upper left panel and the sunken rebate. Again avoiding excess paint being brushed onto the adjacent stiles and rails.
*Lay off the paint lightly, with the tip of the brush, out from the corners of the rebates, otherwise you will get a build up of paint and dripping will occur.
*Check all of the panels and rebates again and lay off any developing runs.
*Then begin painting the upper vertical stile 8 down to 10. The aim here is to coat the door as it was constructed . i.e. paint only up to the joints of each section.
*Then proceed to the upper horizontal rail 11 working your way down to the bottom rail 14. Again only paint up to the constructed joint.
*Finally finish off with the two long outer vertical stiles.
*Check carefully over the whole door for any drips or runs and lay off with light strokes using only the tip of the brush.
*You should now have a perfectly painted and evenly coated Panelled door.
What type of paint to use on an internal door
There are many paints and finishes available on the market today. These are available in oil and water based mixes.
Satin and eggshell finishes are most popular these days as it gives a more contemporary look and feel to the wood.
.5 of a litre will be sufficient for a single coat of paint on both sides of the door.
