Terrazzo Sealant

Terrazzo Sealant
Which sealant should be use for terrazzo floor?

When it comes to sealing cement terrazzo, it's important to choose the right type of sealant to protect and enhance the appearance of the surface. The most recommended types of sealants for cement terrazzo are:

terrazzo 2

Penetrating Sealers (Impregnating Sealers): Penetrating sealers are absorbed into the porous surface of the cement terrazzo, forming a protective barrier below the surface. They are typically water-based or solvent-based and provide protection against stains, water damage, and some chemical exposure. They allow the terrazzo to breathe and maintain a natural appearance.

Acrylic Sealers: Acrylic sealers are topical sealers that create a protective film on the surface of the terrazzo. They come in various finishes, including matte, satin, and high gloss. Acrylic sealers offer good protection against stains and wear, as well as a glossy or satin appearance, depending on your preference.

terrazzo 3

Urethane Sealers: Urethane sealers are like acrylic sealers but generally offer better durability and chemical resistance. They also come in various finishes, including gloss and satin. Urethane sealers are often used in high-traffic areas or commercial settings.

Epoxy Sealers: Epoxy sealers are two-part sealants that provide a very strong and durable protective layer. They are highly resistant to chemicals and abrasion. Epoxy sealers can be used in both residential and commercial settings, but they may require professional application.


When selecting a sealant for your cement terrazzo, consider factors such as the level of foot traffic, exposure to chemicals, desired finish (glossy, matte, etc.), and whether you prefer a surface-level coating (acrylic, urethane, epoxy) or a penetrating option. Always follow the manufacturer's instructions for application and maintenance to ensure the best results and longevity of your terrazzo floor. Additionally, it's a good idea to consult with a professional installer or contractor for specific recommendations based on your terrazzo's condition and use.
