How do you cover up water stains before painting?

Spray the water with bleach on the water stain, also known as a water stain, also known as a watermark. I usually cover the stain with a light mist, then let it work and it soaks for 30 seconds or so. You'll need a primer that blocks stains, such as a simple base for stains in a spray can, 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'll also need flat white paint for ceilings, stairs, hanging cloths, extension bar, safety glasses, roller and cover for painting, brush, paint tray and liner, painter's tape (unless you have a very firm hand) and good music to keep you motivated. Choose a paint or primer specifically designed to cover stains for better coverage. This may indicate “stain blocker” or “stain sealant” on the package.

Check beforehand that it is intended for use with water stains, and then follow the product's instructions when applying it. Painting on water stains (once water damage has been mitigated) can be a complicated project that requires many steps to achieve the desired results. You can paint over water damage to ceilings or walls as long as it is completely dry and has no structural damage.

A carefully applied mixture of bleach and water can remove that watermark from roofs, leaving the roof as if it had never had a water leak. Here are some of the possible causes of water damage to ceilings and walls: roof leaks, water heater leaks, overflowing toilets, or even slow toilet leaks. The Williams Professional Painting team highlights the importance of repairing a roof before painting on stains, adding that water leaks are often due to roof leaks that are damaged near ventilation pipes, chimneys and ventilation grilles. If you decide to paint over water stains from roof leaks, make sure to first apply a good indoor latex primer to the water stain.
