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.?
what i use is a 4 '; mini roller--start at bottom--roll half way up--then brush down ward, keeping straight lines with brush, lightly ,then do top half using same method, when brush comes to wet paint below follow thru, don t just stop, never try to brush paint after it starts to dry, it will roll on you, and never paint in direct sun light, if the surface is hot paint will dry too quick, always paint from dry to wet, stir paint often, practice on scrap material to get the hang of it, even if it a big piece of card board good luck and thanks for asking meWhat is the proper method for painting a door with latex semi gloss so you don't get stop and start lines.?
Roll doors. Two coats.
use a roller. the brush marks arent that noticable when it dries also u could try to let the paint dry just enough to get tacky then take your brush lightly back over it. usually works for me
Don't buy cheap paint. Also, clean door with TSP first.
Use whats called a hot dog roller! really works great!!
1. Have you cleaned and PRIMED the door? 2. Was the paint stirred WELL? 3. Interior paint for indoors and EXTERIOR paint for outdoors. 4. Use a roller. 5.Finally SPRAY (air paint) the door. IT SOUNDS LIKE THE PAINT WASNT STIRRED WELL.
I agree with Dr Dirt, but I would add .. I use a heaver coat of paint That helps hide brush and roller marks, cause the paint is just heavy enough to flow back and fill in the marks.... the thinner you spread out the paint the more marks are left...that and practice is the key.
