Kilz Primer/Sealer: Water Or Oil Based To Use ?

[Robert11]

Hello,

I have a water stain (brownish) on my bathroom ceiling. Problem has been corrected, and I don't expect a repeat.

Would like to put Kilz Primer/Sealer over the stain. Since I don't expect any further leakage, can I use a water based Kilz instead of their oil based product ?

Or, would the brownish stain would eventually bleed thru any water based Kilz, even though the stain is dry now ?

The reason I ask, is that the ceiling is presently painted with a latex paint, and if I have to put the Kilz over the whole ceiling to make things blend well for the future topcoat of a regular paint, I know an oil based product like Kilz oil would probably not go over the presently latex painted ceiling well.

Thanks, B.

I'd use Zinsser BIN - it's shellac. It's a great barrier material that almost nothing bleeds through that.

I use it on walls that have had wallpaper removed, just in case any of the glue survives the cleaning, and have yet to have a problem with moisture activating the glue and doing funny things to the paint I put on over the top.

That's what primer does - cover stains. It is irrelevant what the base of the primer is.

kilz oil based primer appears to work better

I've had nicotine bleed through several coats of the water-based Kilz, and this was on a wall that had been cleaned pretty thoroughly with TSP. I had high hopes for the water-based, but no luck. One coat of the oil-based did the trick. So the type of primer most definitely makes a difference.

That's nicotine, though. I don't know what caused your stain, but it sounds to me like it would make sense to give the water-based a try & see if it gets the job done. It's more expensive, though. Maybe you could find it in quart size. (Our local Sears had gallons only, if I recall).

the water based kilz is worthless. Use the original.
