Hi, can anyone give advise, been a plasterer/renderer for 30+ years,recently bought a ritmo L plus.I've sprayed 350 bags of Weber Mono(I heard about 450-500 is about the right amount),The consistency of the material is just starting to change, will I get a bit more life out of the rotor /stator or is it best to change now.i have a gable end with about 40m2 to do next.Is it worth changing it and keeping it to spray other materials ?Its all new to me.Thanks!
