How to Know What Type of Polyurethane

Polyurethane comes in two variants, oil-based and water-based. Working with it can stain your hands. But before removing it, you need to know the type. Now, how could you differentiate one from the other?

Of course, you would know what type of polyurethane from the product label. But in instances that you can't access the label for whatever reason, you should know how to tell them apart.

Water-Based Polyurethane

True to its name, the primary solvent in this variant is water. This means that water is needed to get it off your hands.

When you wash your hands with soap and running water, you will feel the polyurethane soften. You would readily notice that the substance is clear and light in color.

Another way to determine if it is water-based is when the substance softens and dissolves when you rub your stained hands with a cotton ball saturated with rubbing alcohol.

Oil-Based Polyurethane

This type needs a thinning agent to break it down. Paint thinner or mineral spirits are needed to remove the substance from your hands. Mineral spirits are clear liquid solvent that is proven to work fast and efficiently dissolves the substance.

Oil-based polyurethane leaves a brown or amber hue and has a sharper odor than water-based polyurethane.

Alternatives for Mineral Spirits in Removing Polyurethane

Mineral spirits, or white spirit, is extensively used in industrial settings for degreasing, lubricating, and cleaning tools and machinery.

While mineral spirits are considered the best solvent for oil-based polyurethane and other oil-based products, there are also great substitutes. You could use these alternatives and apply the same steps as you are using mineral spirits.

These are common household products and are the safer go-to options. These are recommended because you aren't exposed to harsh chemicals.

  • Baby oil or body massage oil
  • Vegetable oil, olive oil, or coconut oil
  • Salt
  • Peanut butter (creamy)
  • Soy-based polyurethane stripper

The oil-based substitutes are effective cleansing agents. While getting your hands soaked with these products, they effectively loosen the polyurethane bonds. After loosening, then apply salt. Salt acts as a good scrub due to its abrasive properties.

A soy-based polyurethane stripper is recommended since it is bioactive and skin-friendly. It is non-caustic with no toxic fumes. Being plant-based, there is no methyl component.

These harsher products can also work as mineral spirit substitutes:

  • White vinegar or any acetic acid
  • Paint thinner
  • Hand or waterless cleaner

These substitute products should be your last resort. They contain harsh chemicals and are effective with oil-based polyurethane. They are best to apply when polyurethane is still wet. Apply with caution though as they may irritate your skin further.

Paint thinners work as quickly as mineral spirits. However, they have properties that cause skin dryness. Be sure to rinse off as fast and moisturize the area immediately. The waterless cleaner works best for stain droplets while they are still wet.

Whatever product you would use, mineral spirits, alcohol, nail polish remover, or any of their substitutes, always apply a hand moisturizer after rinsing. This step is important since significant moisture loss occurs due to excessive washing and brisk scrubbing of your skin.

Ways to Avoid Polyurethane Stains

Wearing Facial Protection

It is proven that polyurethane's toxicity level is high and hazardous to health. It contains harsh chemicals that have detrimental effects due to prolonged exposure.  However, working on it doesn’t mean you are putting yourself at risk.

As long as you apply the polyurethane correctly, whether oil-based or water-based, you will be safe while using the product. You need to avoid, if not eliminate, the substance coming in direct skin contact as well as inhaling the fumes through the useful pointers below:

Wear Gloves

This is the best approach. Avoid sticky hands at all times. Latex gloves or chemical-resistant gloves are useful for preventing the sticky substance from coming into direct contact with your skin while working.

Wear Protective Clothing

Protect yourself by wearing a coverall. Else a long sleeve shirt, full pants, and closed-toe shoes would do. The clothing fully protects you from drips, splashes, and splatters while working.

Wear Protective Goggles or Face Shield

You should prevent the substance from splashing on your face, especially near your eyes. Even a small droplet can cause severe eye irritation.

Wear Respirator Masks

You should avoid inhaling the fumes while working. Also, keep your work area well ventilated. Inhaling toxic chemicals has a direct impact on respiratory health.

Wipe Off While Wet

In case of accidental spills on your clothes or shoes, wipe off the substance immediately without giving it a chance to dry. This also applies to your hands. Prevent the gummy substance to get dry by wiping it off and washing your hands immediately.
