did somebody recently ask me why they're getting lights on their walls when they're rolling the walls and here's you know a great color a great example and I'll give you some tips and tricks how to not have that happen and in the lines and the walls we call them lap marks um some of them we call it haloing um hat banding there's a lot of different terminology terminology you can use but one of the major causes for it is not keeping a wet Edge so I've already done my cut ends right here if I go to lunch now and I let this dry when I roll up to my ceiling or wall whatever I that's already dried it's not going to be wet that's going to possibly be a different color or it could be what we call half Manning if you start rolling in the middle of the wall and you get this ball halfway done this dries right here and then you start from here going down that wall you're going from wet to dry that is going to show a line or a start and stop right in the middle of that wall and so you don't want to do that you always want to keep a wet Edge I'm going to start rolling this wall right here I've got my cut ends done this is all wet I'm gonna start rolling this wall and I'm getting it as close as I can to that wet Edge and corner right there as I can and then I'm going to be getting rolling down the wall this I've got an unusual job here at trim same color as the ceilings uh same Sheen customer wanted it all the same so now what I want to do in order to not get lines is I'm going to start right in the middle where my wet paint was begin Distributing my pain and now I've got it nice and soft and wet it's overlapped 50 percent three to four inches or 50 percent load my roller back up the other thing is is you're not loading your roller up enough and keeping it super wet the rollers drying out it's what we call on dry napping the wall you want to go no more than one roller length on your wall before moving down to the next section so I unloaded it I'm going to load it back up that way my wall stays absolutely saturated absolutely wet I would overlap it keeping it wet Edge distribute my paint you want to work quickly so this stays wet I'm going to do my layout want to lay my wall out top the bottom another thing is you don't want to come back and lay this out when you've already worked down the wall way down there because you will get lines you will get lap marks this is totally saturated that I've done three laps and I've laid it out and I'm going to do three more if you keep this thing saturated with paint and you do your overlap you will not get lines the walls aren't nearly as hard as ceilings because heat rises so I've got one lap got my wall got my pain saturated lay it out I'll do one more length and then do my layout you can see this is completely saturated and I will not get lines in my lot in my walls as long as I keep a wet Edge thank you [Applause]
