Wagner power painters...?

Trick. I paint and drywall for a living.
When painting exterior stucco or a new fence ,wet it down with a garden
hose, not soaking wet but damp. Work in the shade. The water sucks the
paint in the pores, use this method for the first coat . ( using exterior latex
stain not oil)
Use a brush and roller with a 20 to 30 mm sleeve.
This is a way easier and faster way of painting than using a sprayer,(way
less prep work) . I have been doing this for 25 years.
Hope this helps.
