Overall, the use of cement self-levelling materials offers a number of advantages over traditional concrete. They provide improved surface leveling, quick drying time, and ease of application, making them an ideal choice for a wide range of commercial and residential applications.

Types of Cement Self Levelling Materials

Polymer-Modified Cement Self Levelling Materials

Polymer-modified cement self-levelling materials are the most commonly used type of self-levelling concrete. They are made by mixing Portland cement with polymer plasticizers and other additives. These materials are known for their high strength and durability, making them ideal for use in industrial and commercial settings. They can be applied to both new and existing concrete surfaces, and can be used to level out uneven floors or to create a smooth and level surface for the installation of flooring materials.

Polymer-modified cement self-levelling materials are available in both water-based and acrylic-based formulations. Acrylic-based compounds are created by mixing an acrylic liquid polymer with powder, while water-based compounds are made by adding water to the mixture. Both types of compounds are easy to apply and can be poured as thin as a quarter of an inch, making them ideal for use in a variety of applications.

Gypsum-Based Cement Self Levelling Materials

Gypsum-based cement self-levelling materials are made by mixing gypsum powder with water and other additives. These materials are known for their fast-setting properties and can be applied to both new and existing concrete surfaces. They are commonly used in residential and commercial settings, and are ideal for use in areas with low traffic or foot traffic only.

Gypsum-based cement self-levelling materials are not as strong or durable as polymer-modified cement self-levelling materials, and are not recommended for use in areas with heavy traffic or in industrial settings. They are, however, more affordable than polymer-modified cement self-levelling materials and are a good option for those on a budget.

Epoxy-Based Cement Self Levelling Materials

Epoxy-based cement self-levelling materials are made by mixing epoxy resin with cement and other additives. These materials are known for their high strength and durability, and are commonly used in industrial and commercial settings. They can be used to level out uneven floors or to create a smooth and level surface for the installation of flooring materials.

Epoxy-based cement self-levelling materials are more expensive than polymer-modified cement self-levelling materials and gypsum-based cement self-levelling materials, but are also more durable and longer-lasting. They are ideal for use in areas with heavy traffic or in industrial settings where durability is a top priority.
