Most stained wood has a coat of protective varnish that must be eliminated as well. So, technically you must first use the chemical stripper to clear away the varnish (and some of the stain will lift, too), then sand away a thin layer from the surface of the wood to remove most of the stain.
Wood stain remover should remove most, if not all, of that wood stain on its own. While sanding can be a great final step, especially if you're planning to paint or restrain the wood, it isn't always required. Following the first three steps of this process can leave you with beautiful results.
Removing the stains from wood is possible without resorting to sandpaper. You can use either a liquid stripper or gel. Start by taping up any parts of the wood you don't want to be to be affected by the stripper.
Water-based stains need to be stripped off before you apply a new finish, while oil-based stains can be recoated after you use a deck cleaner. To test the stain: Apply a small amount of deck stripper to a small area on your deck. Let it sit for about 15 minutes, then wipe it off with a cleaning rag.
Sand the Surface
Apply only enough pressure to take off any residue and rough areas. Wipe off dust with a tack cloth, switch to 180-grit sandpaper and continue until every inch is smooth.
Sanding does help to lighten wood in many cases, but this only applies to surface soil or grime, and even then only if the discoloration has not penetrated very deeply. In addition, heavy sanding is not always practical. It may result in changing the contours of the piece, or in removing more wood than is advisable.
The Pros Of Stripping
The finished product is raw wood: Stripper helps you get to the bare wood of the surface without damaging the wood grains. You can still achieve this with sanding, but it's harder to reach the grain with sanding and it's easier to damage the wood in the process.
Wood stain is intended to be wiped off immediately after application. If the wood stain remains on the wood, liquid solvents in the stain will evaporate, leaving sticky pigments behind that will never fully dry. To remove tacky wood stain, firmly scrub the piece with mineral spirits.
Depending on your project, you will not need to remove old stain before restaining. If you want to darken the stain on your wood project, then removing the existing stain is not necessary!
No, the sticky stains will not dry after some time, which is why it is important to wipe off the excess wood stain. If you don't, your work will end up sticky because the stain did not dry properly. You will have to use mineral spirits, more stain, or sandpaper to fix the mess.
After staining wood, you will want to finish with a topcoat sealer to protect your wood project. Apply a sealant and let it fully cure before handling!
Even though vinegar is a natural, safe cleaner and disinfectant, the acidic formula is also tough on stains and safe for wood. Soak some paper towels in white vinegar and layer them over the stain. Let the soaked towels sit for about 30 minutes to penetrate the stain.
Thankfully, most watermarks are not permanent, and it's almost always possible to get rid of the stains from your wood surface, depending on the intensity of the stain and condition of the wood.
1. Apply white vinegar directly to the stain, let it soak in for a few minutes (don't let it dry). 2. Wash the garment in your machine using the hottest water the fabric can tolerate.
Sand away the stain with 150-grit sandpaper.
Switch to a finer sandpaper once you reach the bare wood. Take 150-grit sandpaper and sand the stain directly, again along the grain of the wood. Continue sanding until you remove the whole stain.
Despite what you may have heard — or maybe your own last attempt — you absolutely can paint over stain beautifully and durably. The key to getting a professional result is recognizing the projects that will require more work, then choosing a paint that accommodates both your aesthetic and your patience.
And you certainly can paint over stain, choosing the method that best suits the type of stain on the surface and the kind of paint you wish to use. Keep in mind, however, that proper prep is essential; skimp on these steps and tannins from the stain would likely bleed unattractively onto the fresh paint.
Stained wood nearly always has a protective finish of some kind, and this needs to be removed before painting can occur. While there are chemical products that can achieve this, most people choose to use sandpaper to scuff up the surface. As long as the glossiness is removed, your new paint can stick to it.
To get rid of the excess stain now, take a cloth dampened with mineral spirits and use that to scrub down the piece. This should remove the excess stain. Alternatively, apply another coat of stain, wait a couple of minutes for it to soften up the old, tacky, excess stain, then take a cloth and rub away the excess.
Old t-shirts are great for this, but even paper towels work for smaller projects. But again, I can't stress enough how important it is to wipe it down with a clean dry cloth. Don't slack off on this part.
Minwax® PolyShades®
PolyShades stain and polyurethane also allows you to easily change the color of your currently stained or varnished wood without stripping. Over old varnish you can change the color without removing the old finish or hiding the grain.
Sand out the stain
If you are looking to save some time, then a much easier option is to use an orbital or belt sander. Once you've finished machine sanding, we recommend you sand by hand with the grain of the wood using the same grit sandpaper you were using in the machine.
Sand the Wood
Once the surface has thoroughly dried, sand it using 120- to 220-grit sandpaper to remove any remaining wood stain and finish.
Oil stain can be modified to some extent if you don't like the effect. If the wood is too dark, soak a clean cloth in turpentine or mineral spirits and rub the wood firmly and evenly along the grain. This will lighten the stain but not remove it.
