• Tabletops and other surfaces subject to abrasion. Provides maximum durability with just two coats. Apply thin coats to prevent drips and wrinkles from forming. Available in gloss, semi-gloss, and satin. Apply with: natural-bristle brush - Source: Internet
• The most important factor is the temperature and humidity of your work area. Polyurethane can take anywhere from 2-8 hours to dry, depending on these conditions. If it’s too hot or humid, the polyurethane will dry too quickly and won’t have enough time to level out, resulting in a rough, uneven finish. - Source: Internet
• Swirl it on lightly, don’t try to apply it in straight strokes. If you find that you missed a spot, don’t try to fix it. Just cover the table the best you can and then do not touch it. The surface shouldn’t look like it’s soaking wet when you’re finished. You also shouldn’t see a bunch of brush/cloth marks if you’ve done it correctly. - Source: Internet
• To remove oil-based poly from a paintbrush, you’ll need some chemical solution, using either white spirit or paint thinner. Whereas cleaning water-based poly from a brush requires thorough flushing with water and drying. There are methods available for both types of poly. - Source: Internet
• : Insert the brush into the soapy water and bend back and forth to ensure every part of it gets into the water. Let the brush stay for 10 minutes if you’re using vinegar. Step 3 : The water in the first cup will have turned dark brown. Remove the brush and put it inside the bowl of clean water for about 15 minutes. - Source: Internet
• Thin your polyurethane based on volume, with common ratios being 50/50 or 75/25 of polyurethane to thinner. Stir gently to mix evenly. Don’t get too precise in your measurements; by eye is fine. I always decant into a clean container before applying the thinner. I normally don’t mix up too much thinned product as the thinner will keep evaporating as you progress, and your coating gets thicker and thicker. - Source: Internet
• Step Three: After you’ve let the brush sit in the solvent for a few minutes, it’s time to rinse it off. Run the brush under some warm water and watch as the dirt and grime slide right off the brush bristles. You need to also make sure the soapy water mixture is completely removed, as not doing so could lead to problems later on. - Source: Internet
• If you’re applying polyurethane with a water-based polyurethane, you should use a brush with synthetic bristles. They don’t absorb as much moisture as natural brushes and are cheaper. Using synthetic brushes will also ensure an even coat. - Source: Internet
• The foam applicator absorbs poly thoroughly, preserving the moisture long enough for you to complete your project. Plus, the frame and roller cover included are reusable. You can paint, stain, varnish, or apply polyurethane with the paint roller. - Source: Internet
• You can also use any foam roller by wrapping it in plastic, then with a cloth. The homemade applicator works perfectly for wipe-on polyurethane finishes and helps lay down polyurethane without lap lines. More importantly, it keeps the roller from absorbing the liquid, which also makes clean-up easier. - Source: Internet
• Because paint thinner is a toxic substance for cleaning your polyurethane brush, you’ve got to opt for a safe, non-toxic, and fast way. One of the safest ways is to use mineral oil or baby oil.

• Mineral spirit is the most preferred chemical to clean that polyurethane. But, you may apply thinner or turpentine instead of mineral spirit. Vinegar is another option that can remove polyurethane, so you consider that too. Considering vinegar is alcohol-based [made by fermenting alcohol (ethanol) with acetic acid bacteria], it can easily remove oil-generated polyurethane. Follow the simple way of cleaning oil polyurethane given above and ensure your rinse the brush finally with water to maintain the integrity of the bristles. - Source: Internet
• If the polyurethane being applied is not an waterborne one, you can use mineral spirit after the final coat. You will need to use mineral spirits in a well-ventilated room and make sure that you are working in a well-ventilated space. The mineral spirits should be applied only to the bristles of the brush covered with polyurethane. Never put the ferrule or metal portion of the brush in the liquid. - Source: Internet
• Natural brushes are made from animal hair. Some people prefer working with natural hair bristles, and a paint brush made of such hair will always be sought after. Natural bristles can keep a painter’s work from looking artificial. - Source: Internet
• When the mineral spirits turns into dark brown color, take the brush into next cup. Repeat the process explained in step 2 in rest of the cups. Wait patiently in every cup until the color is changed. You may require maximum five minutes in every cup to get the brush is ready to move into the next cup. Three or maximum four cups of mineral spirits should be enough to reach the point where color no longer changes despite slushing the brush around in the cleaning agent. - Source: Internet
• polys work best on flat surfaces where it’s important to build up a durable film. Brushes hold a lot of finish, so you can cover a wide area each time you load them up. Wipe-on polys are best for contoured surfaces—crown molding and stair balusters—where brushing might create drips. Wipe-ons form thinner coats than brush-ons, so use them when wear isn’t a concern. - Source: Internet
• polys are best for contoured surfaces—crown molding and stair balusters—where brushing might create drips. Wipe-ons form thinner coats than brush-ons, so use them when wear isn’t a concern. Spray-on polys come in handy on hard-to reach surfaces, such as shutter louvers and chair spindles. Aerosol sprays require good technique to avoid drips, and extra prep time to protect surfaces from overspray. Their thin films aren’t as tough as the ones you brush on. - Source: Internet
• After applying polyurethane, you should thoroughly clean your brushes after each use. The first step is to flush the brush with clean water. This will remove most of the polyurethane. Then, store it in a jar of water to absorb any remaining material. - Source: Internet
• Don’t thin semi-gloss or satin polyurethane as they contain flattening agents. According to FineWoodworking, “varnish containing flattening agents should not be thinned beyond what it calls for on the can. The flattening agents will not stay in suspension and white streaky areas may result.” If you want a satin or semi-gloss finish, you’ll need to do a full-strength final coat with a brush. - Source: Internet
• When the water is clear after soaking, you can be sure that the majority of the polyurethane has been removed from your brush. Once removed, you need to run your brush underwater. For water-based polyurethane, you do not need warm water. Cold water will do the job, it is also better for the bristles on your brush. So better take advantage of the opportunity, since this whole process is to maintain the new condition of your brush. - Source: Internet
