A Better Way to Tell To tell if it is still good, start with a visual inspection. Discard finishes that have become thick, rubbery, stringy or separated, as well as those with a skunky odor or obvious mold growth. Ditto for water-based paint or finish that looks like cottage cheese.
Yes, you can stain wood that has already been stained, but there are some important considerations to keep in mind: Type of Stain: If the existing stain is oil-based, it's best to use an oil-based stain for the new application. For water-based stains, use water-based products.
Most opened stains can last 12+ months if stored correctly with the lid tightly sealed.
Sticky varnish occurs due to improper drying, excess humidity, or thick application. Fix it by: 1. Wiping with a mild solvent like mineral spirits or denatured alcohol. 2. Lightly sanding with fine-grit sandpaper (320-400) and reapplying a thin, even coat. 3.
To fix a stain on wood flooring, you can use a wood stain marker or touch-up pen that matches the floor color. For larger stains, consider using a wood filler or applying a matching wood stain. If the stain is deep, sanding the area lightly and refinishing it may be necessary.
It might sound like the makings to your favorite salad dressing, but believe it or not, a little oil and vinegar might be all you need to bring your favorite old wood dresser back to life. Mix ¾ cup extra virgin olive oil with ¼ cup white vinegar and then apply it with a piece of cheese cloth.
Blotchiness is caused by irregular pores, most often found in maple, pine, alder, aspen, poplar and birch, that absorb stain unevenly. The best way to reduce blotchiness is to apply a coat of Minwax® Pre-Stain Wood Conditioner after your final sanding, but before you apply your Minwax® stain.
For tougher residue or sticky spots, consider using mineral spirits. Apply a small amount to a clean cloth and gently rub the affected areas. Remember to test in an unnoticed area first.
Just wipe the wet surface with a lacquer thinner rag or with acetone either one. Make sure to use a WHITE RAG. Wear gloves and respirator and keep away from sparks and flames. Both of these solvents evaporate very quickly and will loosen the tints and paraffins that delay dry times in stains.
If you used a penetrating oil stain, you may have allowed the stain to build up too thick a coat on the surface of the wood. Penetrating wood stains are not intended to be a surface finish. If applied too thickly, they won't dry properly and will remain tacky to the touch.

If the existing stain on the furniture is oil-based, you must apply oil-based stain on top. If the existing stain on the furniture is water-based, you must apply a water-based stain on top. Oil and water don't mix, even in furniture refinishing.
Professionals re-stain decks every 2-3 years to maintain the lumber's health and beauty.
Therefore, it's best to save your oil-based paints and stains for a household hazardous waste collection program or to contact your local/state government environmental protection agency for guidance. States with PaintCare will collect and dispose of leftover oil-based products.
Solid Outdoor Stains: Restain every 3-5 years
We look at staining exterior wood as a long-term investment in your home. There are many factors that can increase or decrease the lifespan of an exterior stain job.
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.
Mineral spirits, also called paint thinner or mineral turpentine, prepare wood surfaces by gently cleaning the top layer. The liquid doesn't make the wood swell, thus damaging it or changing its size, but rather wipes off any stains, especially oil. It also dries quickly when rubbed over a wooden surface.
Try spraying the affected area with a water displacement lubricant like WD-40® to reactivate the stain, let sit for 15-30 minutes and then try the liquid dish soap treatment again.
Reapplying Stain Correctly
Lightly sand the surface with fine-grit sandpaper to ensure an even surface. Wipe away any dust with a tack cloth. Reapply the stain liberally, working in small sections. Immediately wipe off the excess with a clean rag, moving in the direction of the wood grain.
Vinegar proves to be a cheap and harmless substitute for commercial cleaners. It efficiently removes dirt and rejuvenates wooden surfaces due to its acidic nature. It doesn't contain the dangerous chemicals found in many commercial cleaners.
Applying the second coat too soon can result in peeling or uneven coloration, while waiting too long may hinder absorption. Manufacturer Guidelines: Most stains recommend waiting at least 4 hours between coats or until the first coat is completely dry.
This can happen if the wood wasn't properly cleaned, or prepared, or if the stain was applied too thickly. Humidity and Temperature: High humidity or colder temperatures can slow down the drying and absorption process of oil-based stains into the wood, causing the stain to remain sticky.
Re-Stain the Wood
Use a paintbrush or foam brush to apply a thin, even coat of stain. Wipe off any excess stain after a few minutes to prevent further blotchiness. Allow the stain to dry according to the manufacturer's instructions.
Remove the Lap Marks With Thinner:
In order to remove lap marks from a stained surface, you can soak a clean cloth in paint thinner and rub the cloth over the dark areas of the lap marks. As a result, the lap marks will slowly begin to disappear and remove some of the stain.
