Once the layer of primer is completely dry, the painting fun can begin. If it's textured, consider a sprayable primer for easy application. If it's smooth, a roller is generally easiest. Unlike latex paint, these stain-blocking primers also contain a high volume of binders (polymers that bind paint pigments), so that the primer can effectively adhere to the surface over the long run," writes Manasa Reddigari on BobVila.īefore you apply the primer, look at your ceiling type. Oil-based stain-blocking primers are water-insoluble, therefore, water stains cannot bleed through. "Your best option for a base coat to cover water stains on the ceiling is an oil-based, mold-resistant, stain-blocking primer in a shade closely matching that of the existing ceiling. But regardless of the types of wall primer you've chosen, it's essential to carefully consider the proper application process as well as the fact that latex primer isn't right for this specific job. Studies have shown that levels of several VOCs average two to five times higher indoors than outdoors, and when inhaled they can contribute to several health problems. Finally, let the ceiling dry and cover the trim with painter's tape to prepare it for the next steps of priming and painting.Īs we discussed above, it's always ideal to use low VOC painting materials, including wall primers. Then, spray some warm water and gently rinse the area. After spraying the solution onto the stain, make sure to wipe the area gently with a clean sponge. This helps the stain to start fading and also removes mildew, dirt, dust, and other debris. But don't just spray bleach on the stain itself - it's best to create a solvent made with one cup of bleach and three cups of warm water. As with any home improvement project, it's generally easiest to gather your materials first.īefore you actually do any painting or priming, you need to clean the area thoroughly, just as you would with other painting projects. The other materials you'll need to complete this project include bleach, a drop cloth to prevent spills, protective gloves, goggles, a sponge, a spray bottle, a sponge, painter's tape, and potentially, a ladder. For this reason, it's always worth it to invest in low VOC paint and wall primer. Traditional painting materials contain high levels of volatile organic compounds (VOCs), and according to a report by CBC Marketplace, VOC levels over 500 ppb could cause problems for people with chemical sensitivities. It's also important to mention that this process involves the use of wall primers and paints, and we understand better than anyone that quality makes a major difference when it comes to the results as well as your personal health. Once you've resolved the cause of the problem and are sure that the water stain is dry and won't get worse, it's time to gather the materials you'll need. Here's our homeowner's DIY guide to removing water stains from ceilings and walls with paint. However, a few simple steps is all it takes to get your ceiling looking as good as new. Unfortunately, many homeowners just don't know what to do when a water stain makes its way across their ceiling and continues to spread. That may be a bit extreme, but they're at least unsightly and can easily cause further damage if the cause is not addressed and resolved. Water stains are a homeowner's absolute worst nightmare.
