I'm considering applying it on my treated lumber Three Rail Corral Fence.

I've tried Behr Premium Semi-Transparent stain - applied it properly and in less than a year it's beginning to flake off.

I applied two coats of Behr with a brush as it requires "back brushing" - The Kilz doesn't, so I can spray it on. Using a brush was grueling as I've dog wire sandwiched between the posts and rails.

The Kilz says it's only a one coat application as it's quite thick.

I applied a test section of the Kilz with a brush (don't have my sprayer yet) and the brush strokes show streaks threw to the original black stain... The Kilz is white in color. It comes in white or red only. However, perhaps (I hope) the Kilz will still require only one coat as spraying won't (shouldn't anyway) show through as they'll be no brush strokes when applied with the airless sprayer. Of course, I could be wrong and I'll have to apply two coats to prevent the old black from showing through.

Anyone here know if one coat will do the job or is there another paint you'd recommend where a sprayer can be used.

P.S. With applying white I'll be able to see where I've missed any unpainted sections, though I'd prefer using black again...

Thanks!

I have used Kilz, but not on a fence. I do know that there are two different ones. The Kilz 2 covers up smoke damage. I would think it would work.

You can have Kilz tinted to come closer to the top coat color. It'll never be black, but starting with the red and making it maroon will show better if choosing a dark finish color. I have sprayed Kilz quite a bit with great results. One coat is usually enough to hide the old stain and allow the top coat to stick. A top coat will be necessary as Kilz does not have UV protection and is not designed for exposure. Kilz2 is latex and recommended for exterior jobs.

I don't know the age of the fence, but treated lumber needs to dried out for six months before any stain or paint is applied. It might be why the Behr stain failed.

I suspect the problem is the treated lumber. By design, it blocks moisture penetration, so the stain can't penetrate. There are different kinds of pressure treatment, so you'll want to know what yours is before you ask the paint guy what you should use.
