How Long After Sanding Can I Stain (And Why)?

Exact Answer: Two Days

Wood stain is a type of paint used to color wood, and it contains colorants that typically dissolve into a good suspension. Applying an exterior wood stain to window frames, decks, and outdoor furniture helps to safeguard your wooden materials from being destroyed with algae, molds, and rot.

Furthermore, it also provides a waterproof coat, thereby protecting the materials from water damage. However, the main issue usually is waiting for the stain to dry completely between the coats. This becomes more confusing since people are generally uncertain about the duration it takes for the stain to dry fully so that you can embark on applying a second coat.

There are various types of external wood stains, so it is no surprise that there are different ranges of colors. You can find stains that can be applied within a couple of hours, whereas others take either one or two days for proper application, and this is mostly the case with thick stains. Additionally, some stains are non-penetrative, and the woods can take approximately weeks to get the final texture. When dealing with these non-penetrative stains, you should first leave them for roughly a week or more before applying the second coat.

Furthermore, different stains vary in the duration of application after sanding, so you should be specific about the stain you want to use.

Why Does It Take That Long After Sanding To Stain?

The type of stain you use determines how long the drying times will be and when to apply after sanding. Some brands usually take five to eleven hours to dry, whereas others take approximately twelve to twenty-four hours to dry. Therefore, it is up to you to decide which brand to use as different stains have drying durations that vary. This is a significant factor that determines how well your stain dries. The ideal humidity levels range between fifty to seventy percent, and high humidity levels slow down the drying process. However, if you want to achieve the best results, the optimum humidity level is fifty percent.

The temperature of the place you are working from has a profound effect on the drying duration. Temperature ranging between fifty to ninety degrees is ideal as it boosts the stain drying process. Nevertheless, expect longer drying times if the temperature is at its lowest or highest point, with the optimal temperature for drying your stain being seventy-five degrees. This is more applicable if staining is being done indoors, and then it plays a crucial role in the staining process. Proper ventilation does not only keeps you from inhaling dangerous fumes but also fastens the drying process. Therefore, it is appropriate to maintain good and proper air circulation to enhance the staining process further.

The above-mentioned reasons that affect the drying are the ones that decide the time gap between sanding and staining. If the drying time is less, then it is applied late so that the sanding process is done correctly. In contrast, if a stain dries slowly, it is applied earlier as it doesn’t stop the sanding process.

Conclusion

Overall, it can be concluded that wood stain is primarily used to paint the woods to be not affected by further surrounding changes. Sanding is done before staining, in which sand is applied to the wood for texture purposes. It is not advised to stain wood immediately after sanding.

On average, there should be a time gap of two days between sanding and staining so that the sand gets appropriately embedded in the wood. The exact time depends on the drying rate of a stain. The same stain to be used can only be decided after knowing the type of wood and the purpose for which staining is done.
