What is the best paint to cover water stains?

Our personal recommendation would be to use Zinsser Coverstain, which is an oil-based anti-stain primer with 6% low odor. Zinsser Coverstain dye can be used on both interior and exterior walls and is especially effective for nicotine and water stains. To cover the stain, you'll need a specialized stain blocker (such as Zinsser Cover Stain (opens in a new tab)) or an oil-based paint. This creates an impermeable barrier that the water stain will not be able to penetrate.

In my opinion, the best paint to cover and block a stain is the oil-based base. It's a shame about the drying time and the paint fumes. The PS1 primer is a great alternative, it dries quickly and doesn't stink. You'll need an anti-stain primer, such as a simple spray stain primer, or you can paint it with a brush and roller.

Our favorite stain blocking product is the Sherwin Williams Pro Block oil-based primer. Another good product to use is Zinsser's B-I-N stain blocker. You will also need flat white paint for ceilings, a ladder, cloths, an extension cord, safety glasses, a roller and a cover for painting, a brush, a tray and a liner for painting, painter's tape (unless you have a very firm hand) and good music to keep you motivated. If painting over water stains isn't an option, you can try to remove as much of the stain as possible with a special solution.

There are several stain blocking products on the market that are good in different ways or for blocking and covering different types of stains. Traditional paint materials contain high levels of volatile organic compounds (VOCs) and, according to a CBC Marketplace report, VOC levels above 500 ppb could cause problems for people with chemical sensitivities. However, depending on the extent of the marks left by water stains, you may want to embark on a much larger painting job than originally intended for better results throughout your home. Gather materials Once you've resolved the cause of the problem and have made sure that the water stain is dry and won't get worse, it's time to gather the materials you'll need.

Follow the tips below to identify and repair the cause of the stains and then clean, print and paint over the water stains to restore the ceiling's flawless finish. Oil-based anti-stain primers (such as KILZ Stainblocking ceiling paint, available on Amazon) are insoluble in water, so water stains cannot leak out. Alternatively, it could be a one-off water spill or increased humidity that leaves an unattractive and unwanted mark. A slow leak in the pipes, or a leaking radiator, could feed the stain and cause it to turn that horrible brown color, which is usually due to rust somewhere in the water system.

The emulsion is a water-based paint, so it does not form a barrier that prevents water stains from reappearing. When a water stain comes into contact with latex paint, the stain dissolves in the wet paint layer as the paint dries, causing the discolored mineral content of the stain to show up again through the paint to the ceiling surface. But don't just spray bleach on the stain; it's best to create a solvent made with one cup of bleach and three cups of warm water. Finally, let the ceiling dry and cover the molding with painter's tape to prepare it for the next priming and painting steps.

Don't start painting a ceiling while it's still damp, otherwise you'll risk further damaging the existing paint and, possibly, the ceiling itself. If you have a smooth ceiling, spread the primer over the water stains with a paint roller with an extension and an 8-inch roll-up cover, then let the primer dry for two hours or as indicated on the primer packaging. Choose a paint that matches the color of the ceiling for a consistent look, and then apply it to the primed area with a roller (choose an 8-inch nap cover for a smooth ceiling or a ¾ to 1 ¼ inch layer for a textured ceiling). .
