How to Stain over Paint

Co-authored by Patrick Coye

Last Updated: November 6, 2021

Stains are a great way to give flooring, furniture, and other objects added warmth. If you're applying stain to a previously painted object, you don't have to strip the paint first. Gel stains can adhere over painted objects without damaging the color or chipping off over time. After cleaning your object and applying the stain, it will have all the vibrancy of a painted object with the warmth of a stained one!

Cleaning and Sanding the Surface

1
Clean the object with a mild solvent. Use dish soap or a mild cleaner to remove any dirt or grime from the object. Dip a washcloth in the solvent and wipe the object's entire surface, then dry it with another washcloth.
- The stain will adhere better to the object if it is free of dirt or grime.
2
Sand the object with wet, fine-grit sandpaper. Spray the object and the sanding block with water, then press the sanding block against the object. Rub the object lightly with the sandpaper in circular motions to remove bumps or minor imperfections.
- Try using fine-grit sandpaper, around 120-grit. This will create a slightly rough surface that the stain can adhere to. ^{[1]

- Avoid applying firm pressure as you sand, as too much pressure may remove the paint.

Wipe off residual sandpaper dust and dry off the object. Dip a washcloth in water and wipe off any dust or grit left behind by the sandpaper. Use a dry cloth to absorb any excess water and, if the object is still damp, let it air dry before staining it.
- After drying the object, you can apply the stain over the paint.
4
Put on a pair of gloves and a respirator. Most stains have a strong color and smell that can irritate your skin or respiratory system. To protect your skin and lungs, put on a sturdy pair of gloves and a respirator before you apply the stain. ^{[2]

- Because most stains can dye fabric, wear clothes that you don't mind getting dirty in as well.
5
Lay out a drop cloth in an open, well-ventilated area. Choose a place to stain your object with plenty of air circulation, preferably outside. Spread out a drop cloth to catch stain drops and avoid staining anything beside your object.
- If you can't stain the object outside, lay the cloth out near an open door or open windows if possible.

Applying the First Gel Stain Coat

1
Use a gel stain for full coverage over the paint. Pick a gel stain in a color darker than the initial paint color. Avoid applying light stains over dark paint, as the stain will be less likely to show up on the surface. ^{[3]

- Not every stain absorbs well over paint, so gel stain is your best option for a rich, even color.
2
Add the gel stain using a foam brush. Dip a foam brush in the gel stain and paint a small section of the object's surface. Inspect the stain coating while you brush the first stroke to make sure you like the color before coating the entire object. ^{[4]

- Avoid using polyurethane or wax-based stains over painted objects, as they're less likely to absorb over the paint.
3
Coat the entire surface in the stain coating. Once you've finished the first brush stroke, continue painting the object from one end to the other, overlapping your strokes for even coverage. Apply the gel stain in thin, even strokes to prevent streaks or a bumpy surface after the object dries.
- Start in an inconspicuous area of the object so that if you don't like the stain's color, you can easily remove it and apply a new one.
4
Inspect the gel stain coat and remove any excess. After applying the first coat, the stain coverage should be thin and even. Check the gel stain for any thick areas and use staining pads to wipe off any residual gel stain.
- For a brighter color that preserves the paint's natural hue, apply thinner coats of the gel stain.

Adding Additional Coats and Finishes

1
Apply 2-3 additional coats of gel stain. Let the first coat dry for an hour, then apply an additional coat using the same technique. Depending on the desired color, apply 2-3 coats over the first layer, waiting an hour for the coat to dry in-between applications. ^{[5]

- The more coats that you apply, the stronger and richer the stain will be.
2
Let the gel stain cure for 24-48 hours. After you've applied several coats, place it on a flat surface. Leave the object to dry for at least 1-2 days before touching or moving it. ^{[6]

- Curing times may vary between different stains. Check the stain's directions for specific instructions.
3
Add a clear finish over the dried gel stain. Dip a foam brush in a clear paint finish and spread it over your object's surface in small sections. Once you've coated the entire object, let it dry for another 30-60 minutes to seal the finish before touching it. ^{[7]

- Clear finishes protect your gel stain from flaking off or fading over time.
- For a smooth, brighter sheen, choose a semi-gloss paint finish.

Expert Answer

Choose a stain-blocking primer that's high in titanium dioxide. It will cost a little more, but you'll get much better coverage.

Tips

Generally, stains should give your object a warmer and darker color. This does, however, vary depending on the color of the stain and paint.

If you previously painted the object a dark color, the stain will show up best if you strip the paint first. You can always paint the object a lighter color before applying the stain, if desired.

Choose a stain made for your object's material for a brighter, longer-lasting finish. If your object is made of wood, for example, use a wood stain.
