Tempered hardboard, also known as tempered masonite, is a type of fiberboard that has been subjected to a tempering process, which involves heating the board under pressure to increase its strength and durability. This process gives tempered hardboard several unique properties that make it suitable for painting.

One of the key characteristics of tempered hardboard is its durability. It is resistant to scratching, denting, and warping, making it an ideal choice for use in areas with heavy traffic or where durability is a concern. Additionally, tempered hardboard is moisture-resistant, making it suitable for use in humid environments or areas where spills are common.

Finally, tempered hardboard is also resistant to warping. This is due to the fact that the tempering process stabilizes the board and prevents it from expanding or contracting with changes in temperature or humidity. This makes tempered hardboard an ideal choice for use in areas where temperature and humidity fluctuate, such as in garages or basements.
