DIY Rolling Walls LIKE A PRO!

What happens here

For this accent wall, green primer is being applied as an undercoat for Venetian plaster. As a second painter performs the cut-ins along the edges (top, bottom, and corners) with a brush, immediately follow with the roller application. This rapid workflow prevents the brushed paint from drying before being blended with the rolled paint. If the cut-ins dry, the difference in paint application (brushed texture vs. rolled texture, and paint thickness) can create visible lines or a 'hat-banding' or 'halo' effect, appearing as a slight color or texture difference. Use high-quality blue Frogtape to mask off baseboards and adjacent walls, ensuring crisp lines and preventing bleed-through due to its swelling polymer technology.

Goal: Apply the green primer, ensuring to work quickly after cut-ins to avoid 'hat-banding' or 'haloing,' which results from differing application methods (brush vs. roller) and drying times.

the next rooms Lucas is doing the cut-in so always good practice especially this now if I was to do if I was working on myself but if I did all these cut ends went out had a sandwich took a break some like that and it was dry and came back and rolled my walls there is a high high likelihood that I'm gonna have what is called um hat banding or haloing once again and that's gonna be a difference in color to your eye to the human's eye of where the cut ends were versus where the wall was rolled and some of that you know it could be attributed to if you do your cut ends and you just brush your cut ends and then you roll your walls where it's brushed the paint is actually applied differently and it leaves brushstrokes and then you go back and you roll your wall you're having stippling and so you're going to see that difference and this is going to be a color difference to your eye and sometimes actually a texture difference same with in the middle is wall if I roll this wall and I stop right in the middle of this wall go off take lunch and then dries right here and then I continue more than likely I'm going to see a difference of a color difference where I started and where I stopped and in a color like this and you know if you get into really really high-end paints high-end paints are less likely to cause half a halfpenny or halo II but there are some really expensive paints to just do it anyways so Lucas is gonna get he'll get his cut ends done top and bottom and then I'll start rolling we're using this is blue tape this is blue frog tape so we're less likely to get any bleeding underneath or on to our baseboards using move on tape the frog tape actually has a polymer that swells when it gets wet or any liquid hits it so nothing will bleed underneath that what's good I'm working out of a 9 inch pan the 9 inch roller because it's just one wall I mean there's multiple options 18 inch rollers no inter fed blowers stuff like that but just to do one wall I don't need anything real big and most of the time you know when we typically you'll see in our videos we're doing our cuttings or brushing it and then we're going back and back rolling it with a four inch roller we're not doing that here because Venetian plaster is going to go right over the top of this so we don't have to be so critical but we're very particular about not leaving a brushstroke on our cut in because I can't get to the ceiling I mean I get to get to the top I can tell me about this short from the…
