Water spots

Going to put new carpet in soon, need to paint walls before carpet comes and the water spots on the ceiling. What will be a good fix for the water spots and will ceiling have to be repainted after covering spots. There is only about six spots, largest eight inches in dia. What will be good to use..........Thanks

 

You will need to use a stain blocking primer on the spots to prevent bleed through of your ceiling paint.Zinsser branded products are excellent choices.Kilz branded is adequate usually.Upper level quality of other brands is usually adequate to very good depending on the brand.You will likely need to repaint the ceiling after priming as primers are flat and not pigmented enough to use as a finish coat,aren't designed for exposure,cleaning etc.Oil based and shellac based primers are better stain blockers but obviously are more involved to use and will cost more.All of this assumes the ceiling isn't actually damaged by the leakage just stained.Buy your supplies at a store that offers knowledgeable saleshelp to assist you.

 

first fix the problem that caused your water spots, otherwise there is no point in fixing them.

Then use an oil based stain killing primer to treat the spots. Either Zinnser Odorless or Zinnser Cover stain work great. You can also use Suprime 14 from P&L. you just need to spot prime the areas. don't use a water based primer as it may cause the spots to bleed. And you can get the zinnser products in aerosol if you want.

Third repaint the ceiling with a good, flat white.

 

I agree with using a solvent based primer to hide the stain - latex primers don't adequately seal the stain. It may be possible to touch up the primer with the ceiling paint but the odds are against it not showing, besides now is a good time to put a fresh coat of paint on the ceil;ing

 

Thanks for info, had a new roof put on last fall and no more leaks. I'll try the Zinnser and I guess if I paint the ceiling now, I don't have to mask the walls. They will be painted next. I have a Wagner air sprayer that has a tank and wand, I should be able to use it for the ceiling.

Thanks again

 

If you spray inside make sure you have everything covered up that needs to be - this includes blocking off doorways and such - overspray can travel a long way Don't forget to wear a respirator!
