RESOLVE Ceiling Painting Problems!

What happens here

The direction of light is a primary factor in the visibility of ceiling imperfections. As a general rule of thumb, you should always roll or spray against the strongest light coming into the room. For example, in the Northern Hemisphere, if a room has south-facing windows, the dominant light will come from that direction, so you should paint perpendicular to those windows. If a room has no windows, prioritize painting against the entrance to the room, as this will be the direction from which most observers view the ceiling. Lap marks are essentially shadows cast by slight ridges or high points in the paint, so painting against the light helps obscure these shadows.

Goal: Always roll or spray the ceiling against the primary natural light source to minimize the visibility of lap marks and other imperfections.

because alighting right John it's all about lighting when it comes to ceilings and so one of the rules that you want to keep kind of a rule of thumb is that you're going to roll against the lighting that is coming into the room so the room we're standing in here we have windows to the north and we have windows to the south now because we're in the Northern Hemisphere all most of our light is going to come in through that south window it's a really good idea to go against that light so if the lights coming in from Crystal Chris is the light imagine Chris is the light whoa right you want to go this way against that light because if you go down towards the light you're going to pick up all the edges of those lap marks and lap marks really are just high points in the paint that you've left on I'm usually because there's not enough paint on there or it's drying too fast and it doesn't have an opportunity to gel out so what would happen if you're in a room that had no windows well you you just don't you shouldn't be there why are you painting them don't even bay Nick as deputy conceded I even bought and there's probably no doors either in which case we have a conundrum but really what so if that's the case so lighting is our first priority wherever those windows are coming in we're gonna prioritize a south-facing window if the windows around the east or the west same thing you still want to go against the light now if you're in a room with no windows generally what we're teaching our guys is that you want to prioritize going against wherever the entrance to the room is so if you have the entrance say behind here someone's going to walk into that room again we want to go side to side and not towards where that door is again we're just giving ourselves the best odds for if things do dry a little too fast that you're not going to see any of those lap marks so what would happen if you had a scenario where you had windows in a room so I we have that scenario here in this house I believe but what would happen so again your priority is going to be the southern facing window because that's where most of the light is going to be coming in and then the second choice you're going to make after that is going to be where is the entrance to the room so one of the decisions is if you've got multiple windows you're really trying to determine where the Sun is gonna shine in through what window the most ideally yes so if you've got a really like if the house has a lot of shade on…
