What happens here

Flashing and lap marks often occur due to uneven paint application or allowing paint to dry before overlapping. In challenging areas like hallways or ceilings, which tend to be warmer and reveal imperfections due to light, it's crucial to maintain a wet edge. When rolling, this means frequently dipping the roller to ensure sufficient paint is applied and avoiding dry rolling. For spraying, especially with an HVLP sprayer, using an HEA (High-Efficiency Airless) tip (like a Titan 619 HEA) creates a feathered edge, which helps blend overlaps seamlessly and reduces the chance of flashing. Adjusting the room temperature to slow drying can also mitigate these issues.

Goal: To avoid flashing and lap marks, particularly in hallways or ceilings, always maintain a wet edge and load enough paint on the roller or use an HVLP tip that provides a feathered edge.

you have to continue down the hallway and you have to continue keeping a wet edge and keep you know laying out you to paint too and hallways are difficult because you know they're tight close quarters they're probably going to be warmer you know then the rest of the house that turned the temperature down so the paint don't dry so fast and just really load on the pain we mean by flashing so flashing if you if you here's one example of flashing if you look down a hallway and you spraying the hallway and you're going you vertically up and down when it's all dried you're gonna look down the hallway and you're gonna see these lap marks going up and down the hallway and those are what we would call flashing and there's some things a lot of things that could cause flashing it cannot be the painter it could be texture flashing from the texture guy yo spraying vertically going down the hallway so you're gonna see those strike marks going down the hallway you're gonna see that same type of thing on a ceiling if you're not keeping a wet edge you can see flashing caused by the sprayer so wherever you know the direction of the roller is going because you're not keeping a wet edge and you're stippling it stippling will cost flashing because you're laying out your paint when it's like starting to dry and so you're pulling on the paint creating you know peaks and valleys and causing stippling flashing there's a lot of things that cause flashing and it's the unevenness in the look of the paint and sometimes that can be color sometimes it could be texture and different varying things so I'm
