I've seen several of this guy's videos. The creativity and ingenuity it takes to design each layer of stencil, decide how many colors you need, in what order, design the stencils so they hang together, cut them out using whatever tool he uses to make these, line them up perfectly: really tremendous. Applause. Kudos to you. Three questions: 1- Overspray: Why does he not mask off a larger area to protect from overspray? Apparently he does a darn good job of covering up or cleaning off the overspray afterward, but wouldn't it be easier to use a larger stencil, or mask off with some extra paper and tape, or something? Apparently not, since this is his technique. But it bothers me every time. 2- Fumes: How does his whole entire house not stink of spray paint? How do you make that some kind of "surprise?" How do you live without getting asthma and cancer and whatever other health hazards are a risk from those fumes? He's not wearing a respirator, obviously. Most of the time, it's just some room in the house; we don't see whether there is a window open, or a fan, or anything. Spray paint fumes are nasty! How does he protect himself and his family from those noxious chemicals? 3- Time: It takes time for spray paint to dry. Especially to dry enough that it can hold up to an adhesive stencil. How long do these projects take? The more layers of paint, the more time it has to take. Did his girls not enter the bathroom for a week, waiting for this painting project to be completed? This cannot possibly be just one day. Or can it? My experience with spray paint is that it takes some time. Does he have a quick-dry paint that he uses?
Let me answer these for you: 1. The easiest and quickest would be to just fix the hole in the wall. These stensils would work without the bashing holes in your walls part aswell. as they state at the end "it doesn't even look like a hole." The whole consept of making holes in your walls or even "fixing" it with art surrounding it is pointless, even if it does look good. Not to mention he makes a living of these videos so.. Kudos to him as you say. 2. I would guess that he is airing out when and after doing this. However, even in a well ventilated room, doing this without proper protection is inherently stupid, no matter how short the exposure is. no kudos on that part. 3. Most spraypaints have fast curing times, the one he's using in this video seems to be MTN hardcore spraypaint and is dry to the touch in 10minutes. so i guess around 10min pr. layer. the time it takes to make the stencil i don't know. But given the basic shapes and color layers, probably not too long.
hi justin. I am your follower from Indonesia. I want to ask, how do you make this art that you make. honestly I was very inspired and want to try it. Thank You 
felicidades con las estencil me gustaria saber mas de ese estilo de creaciones de esténcil que tipo de materiales usas y como se hacen gracias por sus grandes aportes
Would be much easier and better looking if he just cut a piece of gypsum board, fitted it, skimmed the edges and painted it, or even better if he didn’t make a hole with a hammer 🤷🏼♂️
