- If the roof is to blame, notice and repair crumbling shingles, compromised flashing (the weatherproofing material installed on the roof), or weakened seals around roof vents, all of which can requite way to leaks. If you cannot patch the leak in the roof, y'all may need to replace information technology.

Outset by setting a driblet cloth on the floor below the ceiling stain and propping up a ladder to reach it. Donning protective gloves and goggles, climb up the ladder and wipe downwardly the stain with a clean sponge saturated in the bleach solution. Rinse the bleach solution off the ceiling with water from a spray canteen, so wipe the damp surface area dry with a clean cloth. Once the ceiling is completely dry, comprehend the ceiling trim with painter's tape to protect it from primer and pigment.
Step three: Use a base glaze of stain-blocking primer.
At this stage, information technology can be tempting to slap a coat of pigment straight over the h2o stain and call it a 24-hour interval. However, interior latex paints—which are commonly applied to ceilings—are a poor choice for a base of operations glaze over a h2o stain because they're h2o-soluble. When a water stain comes into contact with latex paint, the stain dissolves into the wet pigment layer as the paint dries, causing the discolored mineral contents of the stain to show through the paint to the ceiling surface once again.

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. Oil-based stain-blocking primers (such as KILZ Stainblocking Ceiling Paint, bachelor on Amazon) are water-insoluble, therefore, water stains cannot bleed through. Dissimilar latex paint, these stain-blocking primers also contain a loftier volume of binders (polymers that bind pigment pigments), so that the primer can effectively attach to the surface over the long run.
Primer (and paint) application depends on your manner of ceiling. If you have a smooth ceiling, coil the primer over the water stains using a paint roller with an extension and a ⅜-inch nap roller cover, then let the primer dry for 2 hours or as instructed past the primer packaging. If you lot accept a textured ceiling, opt instead for a thicker nap roller cover (¾ -inch to i-¼ -inch nap) or spray on the primer using a can of stain-blocking primer.
Stride four: Cover the primer with ceiling pigment.
The primed area of the ceiling will usually be a few shades lighter or darker than the residual of the ceiling, which tin can draw the heart to the stained area. Painting over the primed surface area will assistance color-match it with the rest of the ceiling for a professional-quality embrace-upward.
Whether you lot accept a smooth or textured ceiling, you can apply either a latex (h2o-based) or an alkyd (oil-based) ceiling paint over the oil-based primer—though latex options dry out faster and produce fewer fumes from volatile organic compounds (VOCs) than oil-based counterparts. Just brand sure to purchase ceiling-specific paint (view case on The Domicile Depot), which is normally thicker than traditional pigment and comes in a non-reflective terminate that helps hide small-scale blemishes.
Choose a paint that matches the color of your ceiling for a compatible look, so apply it over the primed expanse with a roller (choose a ⅜-inch nap cover for a smooth ceiling, or a ¾ -inch to ane-¼ -inch nap for a textured ceiling). Let the first coat of paint dry out for upwards to four hours or every bit instructed past the packaging, and so use a second coat for more than even coverage.
Subsequently the second coat dries, the ceiling should look equally though at that place were never whatever water stains.
