Why a patch shows through the paint
Almost always for one of two reasons: the compound was not feathered wide enough, or the texture was not matched. Paint hides colour, not geometry. A patch standing 2 millimetres proud of the wall catches side light forever, and every lamp in the room finds it — feathering it out over 30 to 40 centimetres is what makes it disappear.
The other half of the problem is a trade boundary. When a drywall contractor patches and a painter arrives days later, nobody owns the seam between the two jobs. Doing both with one crew removes that boundary — the person finishing the compound is the person who will have to paint it.
What we repair
Most of the work is small and unglamorous, and all of it is invisible when it is done right:
- Nail pops, corner bead damage and hairline settlement cracks
- Door-handle holes and furniture damage in rentals and corridors
- Water damage, once the leak is fixed — including cutting back to sound material rather than skimming over stained board
- Ceiling repairs and popcorn removal
- Full sheet replacement where the board has failed rather than just cracked
Is drywall different in a coastal house?
The board is the same; what is different is what happens around it. With humidity above 70% for most of the year, water damage spreads 15 to 30 centimetres further than the visible stain, and paper facing holds mould behind a surface that looks intact.
So we cut back to sound material rather than skimming over a stain, and in wet areas we replace with moisture-resistant board rather than standard. A stain-blocking primer over a damp patch buys you about six months.
How long until it can be painted?
Same day for small patches, next day for anything larger. Setting-type compound goes hard chemically rather than by drying, so a repair that would take a day with all-purpose mud is ready in an hour or two.
The step that cannot be rushed is matching the texture — knockdown, orange peel or skip trowel all need to be applied and knocked down at the right moment, and rushing it is what turns a repair into a visible smudge.
How long does a drywall repair take?
Faster than most people expect, and the reason is the compound. Setting-type mud hardens by chemical reaction in 20, 45 or 90 minutes depending on which bag you open, rather than by drying overnight like all-purpose mud. That is what makes a same-day repair-and-paint realistic.
Typical timings: a nail pop or a handle hole is 15 minutes of work plus cure; a 30 by 30 centimetre patch with texture matching is about 2 hours across two visits to the wall; a full sheet replacement is half a day, and the paint goes on the next morning.
The step that cannot be compressed is the texture match. Knockdown has to be flattened inside a 10 to 20 minute window after spraying, and there is no product that removes that constraint.
