I recommend after removing cover plates and other obstacles and masking the switches, outlets and any other problems (fake nails). Start by brushing the edges 3 inches out from the corners and around windows, doors and electrical. Do not paint the window tracks or any plastic or weather stripping on the window or door frames. , then roll the walls and ceiling with a roller, coming close as possible to the corners to wash out the brush marks.
When painting use the largest reasonable brush with long edging and finish strokes following the direction of
the wood grain or corner.
Only use half the bristles, keep the handle end of the bristles as dry as possible.
Pat the side of the brush on the can edge to fill the brush and avoid drips.
Use the widest roller you can with the shortest nap you can.
look at the wall you plan on painting, if it has steps or spikes, you may want a 3/8th's inch nap roller, if it's little
bumps or smooth, you want a 1/4" nap, if you're painting fresh cinder block or ruff siding you may want 1/2 "
or 3/4" nap to get into the crevasse and fill the holes , but these are much messier with more bigger drips .
Don't stick the roller into deep paint, dip the roller in and use the ribbed part of the roller tray to spread the
paint around the roller.
roll the ceiling before the walls.
Use drop cloths to catch drips and the roller spatter ( a fine mist of drops that dust what they fall on )
Clean brushes and rollers until the water is clear ( for latex paint ). For Bushes start with running water or a bucket and flex
(tap) the bristles under the water until the water clears or needs changing then using both hands pull the bristles gently apart,
moving across the brush in small (quarter inch ) groups letting the water rinse out against the handle until it runs clear, then
use a spinner or shake out to remove most of the water, then comb or shape the brush to a nice point for next time. Take good
care of your bush and it will be nice to you when edging.
Rollers can be cleaned by scraping most paint out then with about 2 inches of water in the bath tub roll the roller back and
forth on the bottom until the roller seems clean, then rinse the tub and do it again. when most of the paint is out of the roller
rinse the tub again and with the water running roll until the water clears, use a spinner and a bucket to remove most of the
water or use your hand to squeegee most of the water out . I also helps if you stand the roller on end (on something to catch
the drips ), and then come back in an hour and rinse out the paint ( I know you thought it was all out ) that has collected at the
lower end, ( or the side if the roller tipped over).
you can sometimes use Goof off to remove dried paint, and whatever is under it at times, test and use carefully. Use the
sooner the better, read the label, don't smoke or use near flame.
Prime the walls ( and trim if you must paint it) then Caulk, then apply the finish coat(s)
