Spray-only work
A sprayer can place paint fast and reach rough areas. The operator must keep a steady distance and overlap each pass.
Spray and back roll
A roller follows the wet spray. It spreads the coat and pushes paint into low spots in the texture.
Rough stucco can use more paint
Deep texture has more surface area than a smooth wall. It may need more material for full coverage.
Masking matters for both methods
Windows, doors, cars, plants, roof edges, and nearby homes must be protected. Wind can stop spray work.
The wall decides the method
Some walls do well with spray and back roll. Tight areas, trim, and smooth parts may be better brushed or rolled.
What to do next
Take a close photo of the wall texture and a wide photo that shows nearby windows and plants.
