What is the proper method for painting a door with latex semi gloss so you don't get stop and start lines.?

I am getting stop and start brush lines even though I am flicking my wrist with the brush and I just don't stop and pull the brush away, but I am still getting stop and start lines. Should I be painting from the freshly painted section to a new dry section or starting in new dry section and painting up to a painted section. I need some advice with technique. Thank you in advance for your answers.What is the proper method for painting a door with latex semi gloss so you don't get stop and start lines.?
It might help to take the door off the hinges %26amp; paint it while it's laying flat.What is the proper method for painting a door with latex semi gloss so you don't get stop and start lines.?
Cut in around the door knob..or tape if need be(i dont have painted 37 years)..paint the paint on from top to bottom a brush width at a time..but do pretty quick..do not worry about the marks at this time..brush the whole door then ';tip it out'; meaning start your brush at the bottom of the door either left to right or right to left..your preference put the brush lightly at the bottom and brush all the way tothe top very lightly all in one stroke..this is called Tipping it out....You can use a product called ';floetrol'; available at walmart which is a paint additive that keeps a ';wet edge'; on the paint cuaisng it not to show lap marks, and as well the brush marks will self level and ';flow in';.. This is for latex paint..the same company puts out a product called Penatrol for thinner cut paints(oilbase)

Start every brush stroke in an unfinished area, at an edge. Then brush toward the finished area and sweep the brush up and off the work in the same movement. If you stop the brush and then lift it off or set the brush down on a finished area to start the stroke, it will leave extra paint, which shows up as a brush mark or darker spot.





I personally am a fan of the flat sponge pads.

Try long smooth strokes and don't hesitate. lay the door down flat, that way you don't get drips running down the door. Always go from wet to dry areas. For more info try either diy.com or pbs.org/askthisoldhouse.
Use a roller, you won't get any lines at all with one. I like the finish that they leave much better than what is left behind with brushes - smooth %26amp; seamless.
Cut the lock (S) and the hinges in with a brush. Let the paint dry ...overnght....Next day get your self a 4in roller set up.....start at the top and roll the door as fast as you can......within reason......and follow the rolling with a once over brushing to get the roller texture out. LEAVE the door alone until you re coat the next day......P.S. Buy your supplies at a Paint Store....Sherwin Williams. Glidden, Duron etc.....Wallymart is for the Station Wagon contractors
painting a door is really hard.. go look at some others to get an idea.. the cross sections all go one way and the verticle go up and down...
