Furniture, Wood and Cabinetry Finishing - Bubbled Polyurethane

I used a minwax polyurethane to finish my front door. I woke up the next morning to put on the final coat and found that it had bubbled up in parts of the door. How do I fix it?

I live in Spring, TX so it was cool while I was finishing the door and the sun was hitting the door in the morning.

Help!

Poly needs a steady temperature as specified on the can in order to dry properly. If it dries too fast, the surface can skin over and trap the bubbles before they can escape. The bubbled finish will have to be remove. Perhaps you can sand out what needs replacing.

Hope this helps.

It sure is difficult to find a steady temperature in texas. I sanded and reapplied. Still bubbling.

:(

Wouldn't it be possible fixing a temporary door and finish your front door inside your workshop? I don't expect to much change in temerature in-house. You will also avoid direct sunlight from hitting your workpiece.

Using a minwax product your temp has to be consistant. Even if it's 100 degrees. LOL. Take it in to your work shop and stasin the one side. Allow 24 hrs to dry. Then do the other side. Allow another 24 hrs to dry. A cliomate controlled area would be best, but being in Texas, I understand this is a problem, much like here in AZ. If you have some window a/c units use those to keep the temp in your shop at at least 77 degrees. When you finish the door follow same procedure as the stain. Do one side at a time. If at all possible try to use an airless sprayer. This will allow you consistancy unlike brushing on. will also cut down on the dry time and repeated bubbles because the finish is thicker in certain areas. Good Luck.

And make sure you have a way to be thouroughly ventalated in your shop. Minwax is one if not the most potent stains and finishes I have ever used. When I used them in the cabinet shop I work in years ago, we had to put them in air tight canisters to reduce any chance of spontanious combustion. Alot of stains do this but not as quickly as Minwax. Be safe.

I meant the rags would combust, not the stain. Sorry.

sorry - no workshop in this house! I don't know how I'm going to prevent bubbles.:confused:

work shop aka tv room
plastic drop cloth aka temp door...

quick dry miniwax (same day completion)

sand or screen and wipe down the door with a cloth dampened in mineral spirits before reapplying. It's possible thier are some contaminants on the door. Use a high quality applicator which is intended for urethanes....
