Why is the Sherwin Williams Duration paint streaky despite using Purdy brushes and Woodster rollers?

Hey, can you believe it? We’ve never had issues with paint before, but this third coat is coming out streaky. We’re using Sherwin Williams Duration paint with Purdy brushes and Woodster rollers from Home Depot in a little powder room. Any ideas on how to fix this?
When using gloss or semigloss paint, try to use long, smooth strokes with the roller and maintain a consistent amount of paint being applied.
Take a break from painting. Let it set for about a week, then come back to it. Keep in mind that darker shades usually need a darker base coat. It seems like it’s still pretty wet. It should look more even as it sets.
Any reason you didn’t use a roller?
Stated that it indicated he had done it
I’m detecting a strong paint smell in here. Allow it to dry completely. Make sure to cover all the white spots and leave the room. Once the walls feel dry to the touch and the smell has dissipated, then you can apply another coat.
Was it brand new sheetrock?
If it was, using pva primer is essential.
If it’s not new, it’s best to prime and paint again.
Dark and bright colors contain a lot of pigment and can be tricky for non-professionals.
Seems like they didn’t prime the fresh drywall first, huh? And make sure to wait at least 24 hours between coats
Did you consider that it may not count as a third coat if the first coat isn’t even finished yet? There’s still a large portion of the wall without paint. Maybe you should clarify what exactly you mean by a “coat”. For example, how much time passed between applying the first, second, and third coats?
Pointed out that is where the sink and vanity will be placed so we didn’t need to paint the entire wall.
Green, like other colors, can be tricky. How long are you waiting between coats? Are the walls fully dry before applying the next coat? You don’t have to wait a week for it to cure before recoating, so ignore that advice. The way it appears when dry is how it will look, so don’t expect it to change significantly after curing for 3 to 4 weeks. Also, why are some areas unpainted? What’s that white box section?
Pointed out the location for the vanity, so there’s no need to paint that area since it will be covered.
A common error is putting on additional coats before the initial ones have fully dried. This can cause the roller to pick up some of the still sticky paint, resulting in streaks and uneven patches like the ones you’re seeing here.
Mentioned that the coats were spaced out by weeks!
The key is usually the primer. What type was applied?
Do you know if there was wallpaper previously on this wall? It’s possible that some remnants were left behind and the wrong primer was used on top of it.
Clarified that it was just a bare wall.
Maybe it’s time for a nap.
Try washing with a warm washcloth. If that doesn’t work, there might be surfactants or soap additives in the paint.
It might require 3 coats with a dark color for optimal coverage.
Regarding the edit: the wall had already been painted. We sanded, primed, and applied the first coat. Two days later, we added a second coat. After realizing it still didn’t look right, we waited weeks before applying this third coat. Yes, the paint is completely dry in the video.
Pressure can have the same effect. You shouldn’t press too hard with the roller or try to overwork the paint. Also, avoid lifting and moving the roller across the wall. Keep a consistent motion from pan to wall for the best outcome.
It seems like for “roller ropes,” you should apply less pressure and gently blend out the edges. Ideally, you shouldn’t use any pressure at all.
I heard that with red paint, you might need to apply up to 8 coats to achieve the perfect deep color. I’m also wondering if the paint was stirred well enough. Maybe take it back to the store and see if they can shake it again.
Suggested using a dark blue primer to cut down on the number of applications needed.
You know, it would’ve been better to use a gray or blue primer before painting green. That way, you can achieve a deep, rich look by having a solid base to reflect on. Since all paints are semi-transparent, it might take a few extra coats if you skip the deep base primer.
It may sound strange, but applying a brown primer could have been beneficial. Also, does the paint have a flat finish or a slight sheen? If it has a sheen, you need to maintain a wet edge to prevent streaks. For flat finishes, it’s more forgiving but can still be challenging, especially with darker hues.
Suggested cutting in and rolling as you go. Recommended using a 1/2 inch nap sleeve and maintaining a wet edge. Roll tightly to the cut-in.
I’m not sure, but it complements the wallpaper really well! I painted the room green and splurged on expensive paint (they didn’t have my first choice, so they upgraded me at no extra cost)…every small imperfection is visible and it bothers me!
Let it dry thoroughly and observe how it turns out. I used a light green shade and had to use a brush to create a subtle effect. Surprisingly, it dried even better than expected.
For a heavier application, use a nap roller with a 1/2 inch thickness. Make sure to cut and roll while the paint is still wet. Finish rolling in one downward direction.
‘t worry, everything’s fine! Just apply another coat and make sure to roll in the same direction. When painting, go from left to right in one go without doing it section by section. Remember to paint the edges twice with a brush before using the roller.
