One weekend, one room: the painting sequence that survives its first rainy season

A room painted badly costs paint; a room painted in the wrong weather or the wrong order costs the paint job on top of the room - the peel two rainy seasons later is in this article's middle, not the tins. Six steps, and the patience is in the ones people skip.

The sequence, in order of skipped

• One - the room is empty or centre-stacked and clothed: plastic over what stays, drop-cloth on the floor (a dust sheet over carpet is a mop later), and the doors that will not be used closed and taped. The paint you do not clean off frames is the time you thought you saved.
• Two - the wall, honestly: wash the grease and harmattan film down (sugar-soap strength, rinse, dry), scrape every flake already leaving, sand the feather edge where old meets new, fill the holes and nail-pops and let the filler actually cure, then the dust off with a damp cloth and dry hands. A painted wall is a photographed wall after; the paint is the last thing that can hide a flaw, which is why the prep is the job.
• Three - the prime that is not optional: patches drink, and an unpainted filler spot shows through the first coat as a dull matte ghost - spot-prime the repairs and, on fresh plaster or a colour that is changing family (dark to light, gloss to emulsion), the whole wall in primer. The tin costs little; the two extra top coats you skip because of it cost the same tin twice.
• Four - the cut: corners, the ceiling line, the frames - a brush first along every edge in a loaded-but-not-dripping state, the shoulder of the brush doing the line, your wrist resting on a stepladder not hovering. Tape only on edges you cannot control, and pull tape while the last coat is still tacky, scored with a blade - tape left to cure glues the paint to the wall's future in a jagged signature. Two-handed people use a guard; the desk uses a steady hand and a low price on mistakes.
• Five - the roller, two thin coats, and the drying that means drying: medium nap for textured walls, the W or M pattern worked out while wet, the second coat after the time on the tin - not after the time you think - and the room ventilated but not draughted to the point the paint skins unevenly. Thin coats are not a technique, they are physics: thick paint dries from the skin in and stores its own wrinkle.
• Six - the weather window: the harmattan is the country's paint season for a reason - low humidity lets the coats cure at their rated time, and the dust is managed by the closed-door washdown routine instead of fighting a wet film. The rains are not paintable outdoors, and indoors they buy you a peel at the skirting and a slow skin no brand's formula survives; the two honest calendar answers are the dry season's heart and the harmattan's end, and a room painted in the wet months shows its calendar for years.

The two lines that make it look professional

Cut the ceiling line one brush-width inside the joint and let the ceiling's own paint do the last whisper - the razor edge people admire is the line where two soft edges meet cleanly, and the ceiling is the softer coat. And the frame: paint the woodwork first, the wall second, and overlap the wall's coat a hair onto the frame's enamel - the crisp break comes from the different finishes meeting, not from tape, and it is the trick that makes a room look like someone who knows did it.

What the whole page reduces to

A washed, filled, primed wall painted thin in dry weather is a job that lasts a decade and needs no skill beyond the sequence. The shortcut economy - skipping prep, prime, or the calendar - is a room that looks fine until the first long rain, and the peel on the wall is the receipt.
