WAGNER PRO 119 Exterior Painting Rough wall

Just looking for some expert advice



Going to paint a house wall tomorrow, used my Wagner pro 119 before and was a bit cloggy on the masonry paint, so ive bought a new tip hopefully that will help me,



· Should I thin the masonry paint??

· How do you cover bricks? That don’t need painted next to the roughcast as cellotape wont stick that well, any tips?


THANKS
