Why Is My Wood Stain Not Drying? What’s Causing the Issue and How to Fix It
Get yourself out of a sticky situation
Applying too much stain or failing to wipe off excess stain will leave you with a perpetually wet, tacky surface.
Always apply stain in the temperature and humidity conditions recommended by the manufacturer to avoid issues.
The best way to fix the problem is to sand the surface and start over.
It’s easy to think that applying wood stain is as simple as painting: You just brush or roll it on and you’re done, right? Unfortunately, wood stain is a bit more finicky, and you’re more likely to run into problems. If you find yourself asking, “why is my wood stain not drying,” you can use this guide to troubleshoot your issue and get a solution underway to finish up your project.
1. You Applied Too Much Stain
The most common reason for a tacky surface after staining is applying too much stain. Unlike paint, which sits on the surface, stain is meant to penetrate the wood. If you apply too much, some of the stain won’t penetrate and will congeal on the surface, leaving you with a sticky mess that doesn’t dry completely.
How to Fix It
The best option is to wipe down the surface, do a light sanding, and reapply a thin coat of stain to get an even coloring. Be sure to wipe off the excess before it dries.
2. You Didn’t Wipe Off Excess Stain Before It Dried
Speaking of wiping off the excess, this is another reason some homeowners’ staining projects go awry. Stain isn’t designed to remain on the surface of your project. Anything that doesn’t soak in will partially evaporate, leaving you with tacky pigments that will never fully dry.
How to Fix It
Give your project a light sanding, reapply a thin coat of stain, and be sure to wipe off the excess before it dries.
3. You Didn’t Prep Your Surface Properly
Stain should soak into the wood grain and do its magic beneath the surface. If you don’t sand off the previous finish thoroughly, it will leave the stain just sitting on top, where the bulk of the stain will evaporate, leaving you with sticky pigments.
How to Fix It
Use a low-grit sandpaper to sand down the surface until you see bare wood. Sand again with a high-grit sandpaper before reapplying stain. If the surface was previously painted, you can start with paint stripper and then move onto sanding.
4. The Temperature Is Too High or Low
Stain relies on evaporation to work properly. The solvent evaporates after application, leaving just the pigments and binders behind. Solvents evaporate much more quickly in hot temperatures, which can prevent the pigments from setting into the wood grain. In cold temperatures, the evaporation slows down significantly, which can make the stain congeal on the surface rather than soaking into the wood.
How to Fix It
You can scrape off any pigments that haven’t dried and sand down the surface to start over. Be sure you reapply in the temperature range recommended by the stain manufacturer.
5. There’s Too Much Humidity In the Air
Much like temperature, humidity affects how quickly stain soaks in and dries. In high humidity, the solvent evaporates much more slowly, which can make even a good application feel tacky for longer. In low humidity, the solvent can evaporate too quickly, leaving sticky pigment on the surface rather than allowing it to soak in.
How to Fix It
If you applied in high humidity, give your project an extra day to see if more drying time helps. If not, or if you applied in low humidity, sand down the surface and start over in proper conditions.
6. You Need a Different Stain
Sometimes, the stain itself is the issue. For example, if you’re staining a wood with a high natural oil content, like teak, an oil-based stain may not soak into it properly, which can leave you with tacky pigments solidifying on the surface.
How to Fix It
Sand down the surface and start over with a more appropriate stain. Consider a slow-curing oil-based stain if you live in a hot area, and go with a water-based or alcohol-based stain if you live in a cold climate to speed up the curing process.
When to Call a Pro
Staining wood is a project that just about any DIYer can tackle regardless of experience, but if you run into problems with a tacky surface or stain that won’t dry and risks ruining anything that comes in contact with it, call a professional for help.
It’s also a good idea to call in a professional any time you need to stain antique or heirloom furniture to avoid damaging it beyond repair. Additionally, if you’re working on large projects like an outdoor deck, call in a deck staining company near you to avoid wasting time and money on staining, sanding, and restaining.
If your wood stain is still rubbing off after the recommended drying time, it means the pigments didn’t soak into the wood properly and remain on the surface. There are a few possible causes, including applying the stain in hot temperatures, applying too much stain, or failing to wipe off excess before it dries completely.
Wood stain is usually dry to the touch within 6 to 8 hours, but you should let each coat sit for 24 hours before applying another coat or applying a protective coat over it. If you applied your stain in high humidity or cold temperatures, you may need to wait up to 48 hours for the stain to dry completely.
