Paint thinner and denatured alcohol are both solvents used in the paint industry. Denatured alcohol, a form of ethanol, is used as a solvent in many paint applications, serving as a paint thinner to reduce viscosity and improve flow. It is also used to clean up residual dust after sanding. Paint thinner, on the other hand, is usually made from mineral spirits mixed with other cheap solvents and is used for thinning or cleaning up oil-based products such as paint and printing ink. While denatured alcohol dries quickly with no staining, paint thinner can leave behind a residue.

What You'll Learn
Paint thinner is made from mineral spirits mixed with other solvents
Paint thinner is a solvent used in the paint and coatings industries. It is made from mineral spirits, which are a petroleum-sourced mixture of aliphatic hydrocarbons, mixed with other solvents. Mineral spirits are also known as white spirits and are often used to thin oil-based products such as paint and printing ink. They are considered a weaker solvent, making them ideal for residential use.
Paint thinner made from mineral spirits can be used to thin paint, and it is less toxic than some other paint thinners. There are also highly refined, odourless versions of mineral spirits available. However, it is important to note that paint thinner made from mineral spirits may leave behind a residue, so it is crucial to ensure compatibility with the finish being used.
One advantage of using paint thinner made from mineral spirits is its slower evaporation rate compared to other solvents. This helps to avoid the formation of a thin, unformed paint film on the wall, which can lead to streaking and other issues. By selecting a solvent with a slower evaporation rate, a more desirable paint finish can be achieved.
When choosing between paint thinner and denatured alcohol, it is important to consider their unique properties and applications. Denatured alcohol, on the other hand, is created by mixing additives with ethanol, such as methanol, benzene, and pyridine, rendering it unfit for human consumption. Denatured alcohol is effective for degreasing, thinning shellac, and removing Sharpie marks. It dries quickly and does not cause staining or raise the grain, making it a preferred choice for certain applications.
In summary, paint thinner made from mineral spirits mixed with other solvents offers advantages such as thinning paint, slower evaporation, and lower toxicity. Denatured alcohol, created by mixing additives with ethanol, is useful for degreasing, thinning shellac, and quick drying without staining. The choice between the two depends on the specific requirements of the project and the desired finish.

Mineral spirits are less toxic than paint thinner
Mineral spirits, also known as white spirits, are a petroleum-sourced mixture of aliphatic hydrocarbons. They are used for thinning or cleaning up oil-based products such as paint and printing ink. Paint thinner is usually made from mineral spirits mixed with other solvents. While mineral spirits are a weaker solvent, they are ideal for residential use as they are less toxic than paint thinner.
Mineral spirits are commonly used to thin paint, and there are highly refined, odourless versions available. They are also effective at cleaning brushes and other painting tools. When using mineral spirits, it is important to allow them to fully evaporate before applying the final coat. This slow evaporation rate is a key difference between mineral spirits and other solvents, such as lacquer thinner, which evaporates very quickly.
Paint thinner, on the other hand, can be more toxic and may leave behind a residue. It is important to ensure compatibility with the finish being used to avoid any issues with residue. Paint thinner is also not recommended for cleaning brushes with oil-based paint.
In comparison to paint thinner, mineral spirits are a safer and more suitable option for residential use due to their lower toxicity. They are effective at thinning paint and cleaning surfaces without the same level of health risks associated with paint thinner.
It is worth noting that denatured alcohol, another type of solvent, is also commonly used in the paint industry. Denatured alcohol is created by mixing ethanol with additives such as methanol, benzene, and pyridine, rendering it unfit for human consumption. This type of alcohol is effective at degreasing, thinning shellac, and removing Sharpie marks. However, it can damage certain finishes, such as waterborne and lacquer finishes.
