Topic tags/keywords: finishing poly wiping poly blotching water based question

Long story short, I built a book case out of birch plywood and some home depot molding. I stained it with General Finishes water based stain. It was a nice, rich color of rosewood. Then I made the critical error of using Minwax water based wipe on poly. It picked up the stain and moved it, what was a nice uniform stain is now a blotchy mess. The poly, which was supposed to easily wipe on with a soft piece of cloth, quickly became a mess. “No rag marks or drips” my rear end!

What kind of topcoat should I use over water based stain? I am guessing here; but should I use an oil based topcoat if i use a water based stain? I don’t see a quick way to fix this, I think I am going to have to refinish the side that I destroyed. I am really bummed because this project was going so nicely.

I even posted pictures of it on facebook before the finishing disaster.

Thanks for any insight,

Nate, using an oil base topcoat over the stain will work. Give the stain time to cure and then apply a seal coat of an oil base wipe on poly. After this cures you can either continue with the oil base poly or use the General Finishes poly.

Stain lift-off, such as you are describing, is fairly common. That is why I generally suggest using a seal coat of shellac when topcoating with an oil base poly over an oil base stain application. You could use shellac as a seal coat in this case but I would highly recommend spraying it on since the water base stain will dissolve in the alcohol base of the shellac solution. Putting a seal coat of wipe on oil base poly would be the better approach.

Scott Bryan is correct. You need to use what is called a spit cut (1/2# cut). this will give you the protection between coats needed to keep from lifting stains/finishes. If you need more information, try these guys.
