How to Use Paint Thinner

Sep 20, 2021 | Home Repair, House Painting

Paint thinner is a useful product, but it’s not always used correctly.

The purpose of paint thinner is to thin paints and varnishes for easier application. It also cleans brushes and rollers after using them with oil-based products like enamels or shellacs. However, this solvent has many other uses that you may not be aware of.

Did you know that paint thinner can be used as a cleaner?

You can use it to remove adhesive from wood floors or cabinets, clean up wax drippings on tile floors, dissolve gum in carpeting and even get rid of stains on clothing.

Here are some more examples of how to use paint thinner.

What is Paint Thinner?

Paint thinner is a chemical solvent used to dissolve, blend or thin oil-based paints, stains and varnishes. It can also remove some kinds of adhesives.

Paint thinner does not have the same drying effects as mineral spirits because it contains more volatile compounds

Advantages of Using Paint Thinner

The advantages of using paint thinner are:

  • The paint thinner can clean brushes and rollers much better than water or soap and water could.
  • Cleaning out clogged spray nozzles requires only a few drops in the gun when you’re finished, which prevents rust from forming Mixing two different types of paint together will help when painting over dark colors.

Disadvantages of Using Paint Thinner

  • It is highly flammable, so it should be used with caution.
  • Using paint thinner on metal surfaces can corrode the surface.
  • Paint thinners are strong solvents, which means they can dissolve additional materials like plastic or even rubber hoses if not handled correctly (and therefore must never come in contact with them).

How To Use Paint Thinner to Remove Paint

There are several different ways that you can use paint thinner to remove paint.

You can either soak a rag into the fluid and then wipe off the paint on the surface of whatever needs to be de-coated, or you can dip your brush or roller into the liquid and work accordingly through the paint until you achieve an even coat overall of your intended surfaces.

When soaking a rag into the fluid, make sure that you use a cloth rag rather than a cotton one. Cotton fabrics soak up paint thinner, which can lead to your clothes disintegrating and leaving other materials vulnerable to the solvent’s effects.

Paint thinner is also useful as a cleaner because it can dissolve wax and glue on hard surfaces like tile and wood. You should then wipe away any debris with a clean cloth.

When dipping your brush into the liquid, make sure that you’re wearing gloves and eye protection.

How to Use Paint Thinner as Stripper

Paint thinner can also be used as a stripper for floors or cabinets.

You should:

  • Use paper rather than cloth towels with paint thinner because it will cause the rag to disintegrate and make a mess of your work area.
  • Dip the towel into the paint thinner solution, wring it out until it’s only slightly damp, and then use your finger to apply an even coat over whatever surface has been stained with glue, wax, or paint.
  • Not let any liquid get onto grout lines or natural stone surfaces without first testing whether they are suitable for direct paint thinner application If you accidentally let some of this solvent drip onto floor tile, then you should immediately wipe it up with paper towels and then use a wet cloth to remove any residue.
  • Rinse the rag in clean water and continue wiping until you achieve the desired level of clarity.
  • Clean your brush or roller after each application by dipping them into paint thinner, rather than water

How to Use Paint Thinner as Cleaner

You can use paint thinner to clean floors or cabinets.

You should:

  • Dip a cloth into the solution and wring it out until it’s only slightly damp before applying an even coat over whatever surface needs attention.
  • Make sure that your gloves and eye protection are on at all times when using this product.
  • Wipe away residues with paper towels.
  • Repeat steps 1-3 until you achieve the desired results.
  • Dip your brush or roller into the liquid and work it into the paint until you obtain an even coat over all intended surfaces.
  • Clean your brush or roller after each application by dipping them in the paint thinner, rather than water. You should not use soap and water with this method because it will cause corrosion in your tools.

How to Use Paint Thinner on Wood

Paint thinner can be used on wood surfaces in the same way that you would use it on metal or industrial surfaces.

You can apply a generous amount of paint thinner onto whatever surface is giving you trouble, whether that’s a floorboard with an adhesive residue or a ledge with stubborn paint caking its edges.

If you are too close to the area that needs to be treated, then the fumes will become overwhelming very quickly so this means you need to take precautions beforehand by wearing protective equipment like goggles and gloves.

Once your equipment is on, soak either a cotton ball or cloth into the fluid and lay it over the stain for about fifteen minutes prior to scrubbing it off with a scouring pad.

How to Use Paint Thinner to Clean Brushes

Paint thinner is one of the most efficient ways to clean out your brushes after using them in paint or varnish.

The best method for cleaning your brush in thinners is dipping it in and letting it soak for five minutes, then blindly pulling it through the bristles until you can’t feel anything obstructing or bunching up within them anymore.

Afterward, rinse the brush out thoroughly with water before hanging it by its handle over the wax paper until completely dry.  

How to Use Paint Thinner for Oil Paint and Primer

When you are painting over dark colors, sometimes what’s needed is simply not another coat of paint but rather the addition of paint thinner into the mixture.

Mix equal parts of your oil-based paint and paint thinner into a separate container and then work the two together with either a clean brush or roller until you achieve an even color.

You can also use almost any brand of primer as a base to thin out oil paints, whether that’s what you went to buy it for or not!

Though if necessary, feel free to add up to 50% more thinner than recommended on the back of the can in order to make it easier for application and clean up afterward.

Frequently Asked Questions

How long does paint thinner take to work?

The amount of time that it takes for paint thinner to work depends entirely upon how long the coating of paint has been in place, how thick it is, and whether or not there’s already a solvent within the mixture itself.

Do you need to mix paint with thinner?

No. You can use straight paint thinner when removing dried-on paints or varnish from wood surfaces or metal furniture.

Can you put paint thinner in plastic?

No, you should never use paint thinner on any kind of plastic surface.

Can I pour paint thinner down the drain?

No. You should never pour paint thinner down any part of your home’s interior plumbing system, but doing so will not lead to proper disposal of the substance either because it is both corrosive and flammable.

You can use paint thinner to clean and restore surfaces with stubborn residue, remove dried-on paints or varnish from wood surfaces and metal furniture, thin out oil paints for application purposes or primer base, and more.
