It's only important that you wipe off all the excess before the stain dries. Blotching caused by fast drying. Lacquer, water-based and dye stains dry rapidly. So they could lead to this type of blotching if some of the stain dries before you have time to get it all wiped off.
Letting Stains Sit Too Long
It can be tempting to throw the soiled item in your laundry hamper and let it sit until your next laundry day, but the longer a stain sits, the harder it can be to remove completely—especially it the stain is colorful or greasy. So rinse and treat those stains promptly!
It's best to allow the stain to set for at least 10 minutes before wiping it off. However, remember that the time you'll have to wait will vary. You may have to wait longer (at least 20 minutes) for a darker shade. A lighter shade may require you to wipe the stain instantly.
Because the additional coat is not penetrating the wood, it is simply layered on top, which will cause the coat to be more fragile and will not offer the same level of protection as the proper amount of stain. Additionally, moisture in the wood can not escape, which will result in the stain peeling.
You can also leave the wet stain on the wood for longer before you wipe away the excess - sometimes as long as 15 minutes. This may help you achieve a deeper color. Note: check the label directions for the particular stain you're using to see the maximum time you can wait before wiping off the excess stain.
The longer a stain is left untreated, the less likely it is to be removed. When a spill first occurs, it sits on the surface of the fabric, but over time, that spill can start to react with the fabric causing the fabric to actually change colors.
Even notoriously difficult stains like red wine or ink can be removed from most fabrics. For all fabric stains, it's important to act fast and treat the spot as soon as possible. It's also generally best to blot the stain rather than rub it.
You can leave wood stain overnight because it is part of the drying process. After the first coat, you should allow it to dry for at least 12-24 hours. Follow the same process for the second coat.
We always recommend two coats of stain for any wood project, but you should only apply as much stain as the wood can absorb. Extremely dense hardwoods may only be able to absorb one coat of wood stain. The general rule of thumb is to apply only as much deck stain as the wood can absorb.
All wood stains are toxic in liquid form but become non-toxic after fully cured. This process can take 3 to 30 days, depending on the kind of stain and brand. As the stain dries, volatile organic compounds, or VOCs, release into the air.
Stains and oils penetrate wood best when it's cool and dry. If it rains within 48 hours of applying a treatment, the water will soak into the wood, and try and displace the stain. This can cause a blotchy, flaky look, rather than a smooth, even, coat.
Resist the urge to run it under the hot tap. “Don't add hot or even warm water to a stain, as this can end up having the opposite effect of setting it permanently, particularly if the stain is protein-based, like milk or blood,” says Verity. “Always use cold water for the safest result, but avoid over-wetting it.
1. Act quickly – scrape off solids with a blunt knife and blot liquids with absorbent paper. Never spot-clean any stain with hot or warm water as it can set the stain.
If you stain a deck without cleaning and prepping it first, the results will look blotchy, uneven, and, well, amateur. Any time you save skipping the cleaning stage, you'll spend twice over repairing the botched job.
Dried Stains
Once a stain has been dried it's very hard to remove, but it is possible. If you've already used a stain remover, try using it again. More than likely you'll need to soak the stain or use a more aggressive stain remover. On white clothes, try using lemon juice and placing the garment in the sun.
Applying stain
Don't brush on a coat of stain like you would paint and just wait for it to dry. You'll be frustrated and disappointed when parts of it still feel sticky after a couple days. When wood has absorbed all the stain it wants, the rest just sits on the surface and doesn't like to dry.
Leave a dampness of stain on the wood that dries to a darker coloring. This will take practice to get the coloring even, especially on large and multiple surfaces. Just as with leaving the stain on longer, this technique is easiest to do with a fast-drying stain such as lacquer stain.
If you applied the stain correctly, and it still remained tacky, it could be due to rainy weather or high humidity. Give it a few more days to see if it improves. Another possibility is that the stain was old or came from a bad batch.
Remove staining material with blotting, pressing the surface gently with clean paper towel until you don't see oil lifting off anymore. Next, treat the surface with an enzyme cleaner (Bac-Out and Puracy are great choices) and leave it for at least an hour, but up to overnight.
With staining, you'll know if you've over-applied your deck stain because there will be sticky patches or puddles that just aren't drying—the wood has absorbed all it can, so the remaining stain has nowhere to go.
Using a lint free rag is the best way to apply wood stain because it is great for controlling the amount of stain that is applied and for removing any excess stain. Also, the rag leaves a beautiful, even, and brush stroke free finish. It also can easily be thrown out once finished.
Never apply heat on stains
Warm or hot water should not be used when dealing with stains as heat can make it impossible for the stains to be removed. For washable fabrics, treat it with a stain remover, for example, the Britex Spot N Stain remover which is specially formulated to remove stubborn stains and odours.
When first applied, window tint may appear darker than anticipated. However, as it cures and dries the film will lighten slightly. If after some time your tint still looks wet with no prospect of drying or curing in sight, do not hesitate to reach out to a professional tinting shop for assistance.
Dried stain will feel dry to the touch, not sticky or tacky.
If it feels dry, your wood is likely ready for another coat of stain or a sealant. With oil-based stains, you might notice that it doesn't smell as strong. This can be a sign that the stain is dry.
