Microfiber cloths are not only very good at getting dust and particles off of sanded surfaces but can also be washed and used repeatedly, unlike tack cloths.

This makes them cheap and good for the environment. The way microfiber cloths are used is the same as the way traditional tack cloths are used.

However, remember that water-based polyurethane can be easily absorbed into the rag fiber.

Therefore, if you want to apply water-based polyurethane using a rag, you should use a rag that is not too dirty.

Also, ensure the application time is fast so you don’t lose much of the polyurethane absorbed into the fabric.

When I want to use a rag on wooden furniture, I pour a small amount into another container and dip the rag in that.

Apply the poly by wiping it on the wood in smooth, even strokes. Overlap each stroke a little bit to make sure you get the whole area.

You can apply polyurethane with a brush.

However, there is a negative side to it. You will see that there are marks left and some drips as well. So, you might want to use a rag. This is the right way to apply polyurethane with a rag.

Also, using a brush can leave some parts of the surface uncovered by the polyurethane. It isn’t easy to spread the liquid over the surface using a brush.

How to Avoid Brush Marks?

  • Instead of a brush, use a foam brush or a lambswool applicator.
  • If you use a bristle brush, use one with natural hair instead of one made of plastic.
  • Use paint thinner to thin out your polyurethane and a paint stir stick to mix it.
  • Don’t quickly drag your applicator back and forth using polyurethane.
  • Let the first coat dry overnight, then sand it with 280 grit or finer sandpaper.

Can I use a rag to apply water-based polyurethane?

Using a rag to apply polyurethane is more recommended than using a brush. Using a rag will make it easier for you to reach areas that cannot be touched by using a brush.

However, using rag also has its drawbacks. One of them is that the resulting layer will be thinner than using a brush. Therefore, using a rag to apply multiple layers is highly recommended.

When using rags, you must make at least 5 layers. This will give a longer-lasting and more even result.

Can We Use All Kinds of Cloth to Apply Polyurethane?

Using a rag as a tool to apply polyurethane is something that experts enjoy. Some of the reasons include the following.

1. Easier

Using brushes requires control that can be difficult to obtain. In addition, using the wrong brush will result in a thicker layer than it should be. This is not very good and will be easily damaged and take longer to dry.

2. Less Costly

Using a rag will be cheaper than using a brush. You can use any fabric to apply polyurethane. Even so, it’s a good idea to be more selective in choosing fabrics for polyurethane applications.

One of the recommended fabrics is to use a microfiber cloth. This fabric is specially designed to provide excellent absorption so that later it will not cause lumps in the polyurethane coating.

Although a bit more expensive than regular cloth, microfibre cloth is cheaper than a brush.

Using a brush will also be more costly because using polyurethane is more wasteful. So, using rag is highly recommended for better results and lower costs.

Applying shellac with a rag

Shellac is a polyurethane paint product that is quite difficult to apply. However, some tips and procedures can be followed so that the results can be good and look professional. Here is a review of applying shellac with a rag

1. Use a clean rag

Even though you can use any rag, the recommended rag is a clean cloth. So, don’t wear dirty clothes, especially varnishes that have been done before.

The dirt will stick and dry with the polyurethane if you use a dirty rag. Later these stains will become permanent and difficult to remove. Therefore, make sure you use a clean rag.

2. Clean and Sand the Surface

This process is very important. Not only must the cloth be clean, but the surface to be coated with polyurethane must also be cleaned. If not cleaned later, the liquid will be difficult to stick to the surface and will give bad results.

In addition to cleaning, the surface must also be smooth. So you need to sand the surface. The results will be better and stick more firmly with a smooth surface.

The sanding process is not mandatory. However, for better results, this should be done. If the sanding process is not carried out, the coating results will be rough and will not be good. So, make sure you do the sanding process properly.

3. Soak the rag, not the surface, with polyurethane

It is best if you soaked the rag with polyurethane. This is something that many people often forget. Instead of soaking the cloth, most people pour the liquid onto the surface. This is the wrong way and should not be done.

If you discuss the surface, then what happens is a buildup of hardened liquid. This will make the polyurethane surface uneven. So, dip the rag in the polyurethane and rub it over the surface.

To sand, it properly, do it twice with a different grit. Go with the rough sandpaper such as 400 grit. Then continue with 1000 grit paper for a smooth finish.

Leave the layer to dry for a couple of minutes or leave it depending upon the moment it requires to dry depending on the brand name you’re using. Constantly use the second layer when the first layer has dried out totally. Or else it can ruin the last finish.

When the first layer is dried out, gently sand the layer with 320-grit sandpaper. This will ensure better adhesion between layers. Also, clean the surface properly after fining sand using a lint-free rag dipped in mineral spirit.


Do You Wipe Off Excess Polyurethane?

Yes, runs and drips can be stopped by removing extra polyurethane. This is what many polyurethane cans say for a smooth finish.

Soak a lint-free rag in mineral spirit to get rid of extra polyurethane. Wait 30 minutes after putting on the coat before wiping off the extra. It can run and drip if you don’t remove the extra paint between layers.

Can you apply polyurethane with a shirt?

It doesn’t matter if the shirt is colored or white as long as it is worn out.

If you don’t like cleaning brushes or don’t think you cleaned them well enough because they get stiff, you’ll love these disposable clothes. I hang it over my trash can to dry when I’m done. You no longer have to squeeze and rinse.

How to get a smooth finish with polyurethane?

Clean away grease or cooking oil buildup with a degreaser cleaner like Formula 409 or Fantastik.

Sand, the old finish with fine synthetic wool, then seal it with Zinsser SealCoat. Sand, seal with fine synthetic wool, and then brush on two to three coats of poly to finish the job.

How many coats of polyurethane are enough?

About three coats should be enough. This polyurethane takes longer to dry, so you must wait a while between coats.

More than three coatings are neither required nor recommended. Each additional coat must be rubbed, effectively buffing off half of the preceding layer. So 4 coatings are closer to 3.5 coats.

Finishing with cloth takes a long time, no matter how many coats of polyurethane you apply.

Why is my polyurethane streaking?

Because the polyurethane finish cures before the marks are eliminated, streaking marks appear. This produces a high level of gloss all across the surface.

When using a water-based polyurethane finish, you may see that certain places have a high gloss while others do not.

Should I apply polyurethane with a brush or rag?

Standard polyurethane is applied with a paintbrush, but there are also wipe-on formulas that you can apply with a rag, lambswool, and spray finishes that come in aerosol cans.

No matter what type you use, polyurethane is an excellent protective topcoat for projects that get much use.

How good are wipe-on polyurethane finishes

Polyurethane is said to be simple to use. True, it is simple to implement, but More skilled woodworkers rarely buy this material not because they dislike wipe-on polymers but because they don’t see the point of squandering their money on what is unnecessary.

Essentially diluted regular polyurethane low-cost mineral spirits. You can make this yourself for a lot less money.

Begin with a regular old can of polyurethane. Ensure that the label on the can is made of an oil-based poly.

Water-based polyurethane can be thinned and applied. However, you will not achieve the same effects as using an oil-based finish, and one of its primary selling points is how water-based poly is used?

It dries rapidly, but a thinned oil-based poly will also dry rapidly, so I don’t noticeably see the water-based wiping poly’s point except if I really cannot stand the odors of an oil foundation.

Mainly if you’re using a satin finish that includes flatteners must be divided equally throughout; then, quickly pour some in a container and insert an equal amount of mineral spirits in about a 50-50 mix.

The mixture does not need to be measured. It is not crucial; to assess by sight.

This should thin the poly enough to apply with a cloth or foam brush if necessary.

By adding more or fewer distilled mineral spirits, your requirements get us to the main point.

Why would you buy a wipe-on polyurethane? It’s thick and takes a long time to dry with polyurethane straight from the can.

It allows more time for the dust to be trapped at the end. Alternatively, the end might sag and run on the vertical surfaces and not be absorbed by the wood as soon as a thinner finish Layers of wipe-on poly can be applied.
