It’s generally not safe to stain wood indoors. The smell of the stain takes 2-3 days to wear off and it can be dangerous to your respiratory health. However, light water-based wood stains in indoor areas that are isolated from living areas are common even during the winter.
Have you ever wondered if it’s safe to stain wood indoors? What about staining in cold weather? You can’t be working outdoors and you need to stain indoors.
For most people living in areas with varying seasons, this is a true question while those living in cold climates have already managed their way around this issue.
General safety rules don’t recommend staining wood indoors regardless of the season. You can get a headache or suffer nausea from continuous exposure to staining vapors indoors without wearing a mask regardless of the season. In cold weather when you close doors and windows these dangers become even more prominent.
When can it be safe to stain wood indoors?
While it’s never 100% safe to stain wood indoors contractors have found their ways around this. Here are the top tips from professionals on how to stain wood indoors without passing it out.
Choose water-based wood stains
What’s the difference between water-based and oil-based wood stains? One of the main differences is potency which is reduced in water-based stains. In other words, water-based wood stains stink less than oil-based wood stains.
This is the first step towards any indoor wood staining job even during the summer. While staining wood in cold weather is possible even if it takes longer to dry (2-3 days) you still want a reduced-potency stain not to deal with high stink issues.
Consider adding fans indoors
Indoor fans can circulate air towards the windows. This is an approach professionals take especially when staining wood in apartments. You need to use at least 2 fans that direct airflow towards an open window. While cold air gets inside at least the smell of the stain is not going to be as prominent.
Use a half-mask respirator
Protective respiratory masks are a must, especially when staining wood indoors. Even the best half-mask respirator can show its limits when worn indoors, but it’s the main barrier between you and the chemical odors of the stain.
Can you stain wood in cold weather?
Yes, you can stain wood in cold weather. It normally takes 2-3 hours for the stain to dry and 24 hours for the smell of the stain to go away in warm weather. It can take more than 24 hours for the wood stain to dry in cold weather and more than 3 days for the wood stain smell to fade away.
Staining wood in cold weather is tied to indoor jobs. Make sure you isolate the staining room from the rest of the house first. Ideally, you’d stain wood in the garage where you don’t have to spend the night.
Staining wood indoors can feel like gambling
Staining wood indoors has its pros and cons. It allows you to keep on working around the house during the winter but it can also be dangerous or detrimental to your health. If you cannot postpone staining woods indoors you can at least ensure proper ventilation and proper protective gear such as face masks and gloves to minimize associated risks with what is a job that normally takes place outdoors.
Are wood stain fumes harmful?
Wood stain fumes are detrimental to respiratory health. Wearing a mask and ensuring proper airflow in the area of the staining is essential to minimize health risks associated with inhaling stain fumes. Frequent breaks from a staining job also help mitigate these risks.
How long are stain fumes toxic?
Stain fumes evaporate but they don’t dissipate when you stain wood indoors. These fumes now turned into molecules can be inhaled even a few months after your wood staining job if they weren’t evaporated through good air circulation.
Is wood stain toxic after drying?
Yes, wood stain is still toxic after drying. Stain fumes are volatile molecules that evaporate. But they can linger indoors if you haven’t properly ventilated the area after staining.
Can you stain wood without sanding?
Some types of wood such as plywood can be stained without sanding. Hardwood requires sanding before staining. It’s not recommended to sand wood indoors as dust particles settle on furniture and other objects easily.
Is it safe to sleep in a house after staining?
It’s not safe to sleep in a house with a major wood-staining job for at least 3 days. During this time windows and even doors would ideally be open to ensure the wood is completely dry and that the evaporated stain molecules are cleared.
