Ghost stripes are often difficult to remove and repainting is a good option. If you repaint, first apply a coat of stain-killer primer such as Bulls Eye 1-2-3 or Kilz to the affected ceilings or walls. The stain killer will prevent the stripes from bleeding through the finish paint.
What are the best methods for cleaning ceiling stains caused by ghosting? Use thick bleach and a micro fibre cloth. Use Zinser cover stain. Apply Zinser over the stains. Allow to dry completely. Roll over that area with ceiling paint. Allow to dry again.
That is usually caused by something pressing down on the drywall from the attic. Could be too much insulation or storing something on top of the drywall. Much more commonly it's water/high humidity. Drywall gets heavy when it's wet and softens enough to let the screws pull through.
Take a 4``-6'' drywall knife and hose-clamp it to an adjustable painter's pole (this way, you can work from the floor) and scrape in sections. Use a pole sander when dry to knock off any remaining high spots, then skim coat it with a thinned finishing compound and a 10'' drywall knife, followed by a final sanding.
The problem they are describing is called “ghosting” or “thermal bridging.” While this issue is not harmful, it can be a nuisance. If you've noticed this unusual staining pattern in your home, it is helpful to understand why ghosting on walls and ceilings is happening and what can be done to correct it.
For existing ghosting, Ultra Premium Eggshell paint effectively covers marks. Keeping areas clean and dry reduces recurrence.
Preventing Future Ghosting
Use an Air Purifier: Invest in an air purifier to help capture and remove airborne particles. Regular Maintenance: Keep your heating system well-maintained and change filters as recommended.
The culprit, in this case, is improper taping. Basically, contractors install drywall in sheets and stick it together with drywall mud. Then, tape is put on over the mud before you paint. If that seam is between the drywall and, in this case, an improperly sealed ceiling, the tape will start to lift and form a crack.
As you are applying wet paint to a dry surface, you leave room for new lines that cannot get properly blended in, turning a few simple lines into large patches. It might be a harder sell, but the most effective way to get rid of your ceiling lines is to give your ceiling a completely new coat.
Without warning, odd dark streaks called “ghosting” begin to appear on your walls or ceilings. Soon, the blemishes grow darker, forming along wall studs or ceiling rafters. Before long, a creepy outline of the building's framing starts to appear on the sheetrock along with dark spots on the ceiling and walls.
Floaters usually happen because of normal changes in your eyes. As you age, tiny strands of your vitreous (the gel-like fluid that fills your eye) stick together and cast shadows on your retina (the light-sensitive layer of tissue at the back of the eye). Those shadows appear as floaters.
If you see any cracks you're not sure about, contact a foundation professional. They'll come out, perform an inspection, and if you do have structural damage they'll determine what needs to be done. If you're in San Jose, Sacramento to Fairfield, CA, you can contact us for an inspection!
USE THE DRY ERASE METHOD TO REMOVE STUBBORN MARKS
For better results, cover the board in black dry-erase marker and erase it quickly. Wet makers have chemicals that loosen the ghost marks, thereby, helping get rid of stubborn stains. For very stubborn stains, use propyl alcohol and dry it off quickly.
Unfortunately, there are many things that cause ghosting, and you cannot simply paint over the problem and hope it goes away. Your ceiling or walls will need to be cleaned thoroughly and the issues will need to be resolved, so that the dirty streaks do not reoccur.
The dark streaks on your ceiling are from moisture intrusion. When warm, humid air from your living space comes in contact with the cooler surface of your ceiling, it leads to condensation, which attracts dust, dirt, and soot. Over time, this creates telltale dark streaks and may even promote mold growth.
Using a cloth and a cleaner that is drywall and paint-safe, scrub the marks. If they are stubborn, you may need to paint over them. If ghosting has been eliminated as the cause of discoloration on the walls or ceiling in a structure, it could mean there's mold present.
It's called ghosting. It occurs when soot and dust particles stick to the ceiling.
Problems When Painting the Ceiling
Use the Anti Reflex paint and this will get rid of the roller marks. If painting over paper, you will still see roller marks for a few hours. Leave it to dry over night and these will disappear.
As you work your way across the ceiling, position the roller a foot away from the wet edge and roll the next section into the wet edge, overlapping it slightly to prevent ceiling streaks.
Uneven paint can cause a space to look unfinished, whereas a well-painted smooth ceiling gives a polished feel. Patchy ceilings can also be caused by streaks from the paint roller, brush marks or stipple from an uneven roller.
Simple things you can do to improve your indoor air quality include: Reduce dust by vacuuming regularly and using a microfiber or damp cloth for dusting. Reduce humidity to avoid mold and mildew buildup and change appliance filters regularly. And make sure to test your home for dangerous gases like radon.
A high-performance, water-resistant paint, such as webersil P, may be applied to the building to overcome the issue of ghosting. webersil P is a mineral paint with exceptional long-term durability and performance, and comes in a range of 160 colours.
If thermal tracking occurs in your home, you can try scrubbing the walls and ceiling with a mild cleaner to remove the stain. If that doesn't work, you may need to sand and repaint the surfaces. But that's only half the job. You also want to make sure this “ghost” doesn't reappear in the future.
