These are repaints? AKA people are living in the house with furniture etc. and you're spraying everything?I purchased my first airless sprayer this year. I have a Grace 395. I have painted several whole house interiors with it. I have been using the HEA tips and they seem to wear out quickly, I purchased them because they claim to have less over spray and cause less wear on the pump. I didn't know about flat tips until recently. They are so much cheaper than the HEA reversible tips. When are people using flat tips? is cleaning the clogs really that big of a deal? I strain my paint, my pump has a filter, my gun has a filter and I would get a cone filter that sits behind the tip. It seems like I would only get a few clogs per day. Any feedback on when people use them would be appreciated. I am generally spraying entire house interiors so although I don't want a crazy amount of over spray, everything should be covered.
