The color scheme that is chosen for the home creates the initial impression that an individual has of the premises as a whole. Whether complimentary or unflattering colors are selected, the house will gain an identity of its own when the paint is applied. There are many times that a homeowner misses opportunities to accentuate positive attributes that the home has to offer by failing to choose the best exterior paint colors.
A fellow (actually lives in the same neighborhood) by the name of Wayne Hickey (843-655-0366) painted the ceilings and most of the walls of our house in February 2017. He got paint all over my light fixtures, all over my trim around the doors, and had visible lap marks everywhere on the walls. He came back and rectified some of the problems, but not all, as I have noticed as I have had time to look more carefully at the work he and his assistant did. His assistant had no idea (not a clue) how to roll paint on a wall or ceiling. Some places were not covered. He said he would pull nails for pictures and then re-insert the nails exactly where they were. This he did not do as he promised. He painted over the nails. His assistant had no idea how to use a paint roller. I have painted all my life, and would have done this work myself, but I just had a full knee replacement and the other knee is in bad shape. I just could not do the work. Wayne is a pleasant and congenial individual, but he can not cut in a ceiling or wall to my satisfaction - not even close. He should have a putty knife and wet cloth with him all the time to correct any paint that might get applied where it shouldn't. That is something I always did as a painter. I would not recommend Wayne to paint anybody's home.
Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor.
