This is an outstanding painting method for short or small areas. The choice of roller cover and nap thickness will have a big impact when rolling stucco.
A lamb’s wool roller cover will work the best. These covers are less likely to splatter and will hold their shape. The nap thickness depends on the texture of the surface. Use a 1 or 1-1/4 inch for smooth textures and 1-1/2 inch for ruff textures.
Roller applications should be two coats, even if the new color covers well. Two coats will fully fill the pores and provide the proper film thickness.
Begin with the cut-in. Brush around all doors, windows and other openings. This includes any trim and the wall to the soffits. Allow a brushed border of paint 4-6 inches. This will allow the roller to overlap 2-3 inches creating a better seal.
While rolling always saturate the roller cover and never dry roll. Apply a heavy even coat starting at the top of the wall. Finish rolling in a downward direction to make sure the stipple is in one direction.
