German Smear Debunked. Must Watch! 

@erikaalaram thanks for your input, Erika. Did you, by chance, use tile mortar? Masonry mortar doesn't come off with a power washer.

@GH-qi1wv the process doesn't adhere to paint, unfortunately. You could get away with it if most of the paint is gone, but if many joints are clogged with paint, then it isn't a great option.

@@GermanSmearSpecialist thanks . I guess I have to go with stucco . Thanks
