Redispersible Polymer Powder for Mortar Mix

Mortar mix, also known as mortar ready mix or dry pack mortar, is a very common building material. It’s often used in wall putty, tile adhesive, self-leveling, and gypsum plaster.


Dry mortar mix is crucial for keeping cement mortar ready to use. Typically, dry mortar mix includes additives like redispersible polymer powder. As it improves mortar properties. This improvement happens when you combine water with the dry mix.


Redispersible polymer powder is an important mortar composition. It not only enhances bonding, adhesion, flexural strength, and workability. But it also reduces fluid-loss, gas migration in various construction materials.


1. Bonding and adhesion. Sticks better and adheres well.
2. Flexural strength. Withstand bending and stress.
3. Reduce water loss by retenting the fluid content.
4. Improve gas migration and workability.

Have any questions for us? We have answers, most of the time.

What is stronger concrete mix or mortar mix?

Concrete Mix
The concrete mix contains cement, sand, gravel, or stone.
It’s a strong and durable combination. Mainly used for building foundations, sidewalks, and driveways.


Mortar Mix
Mortar mix contains cement, sand, and water. It is not as strong as a concrete mix.
It is commonly used to hold bricks or stones together in walls and for small masonry projects.


Concrete mix is generally stronger than mortar mix. As it contains additional components like gravel or crushed stone, suitable for heavier-duty construction. Mortar mix is designed for bonding bricks and stones in walls but is not as robust as concrete.

What is the chemical composition of redispersible polymer powder?

RDP polymer powder is made mainly from Vinyl Acetate (VAE) and Ethylene. Occasionally, it might also have Polyvinyl Alcohol (PVA).


Redispersible polymer powder is produced through spray-drying VAE emulsions. Adding RDP powder to mortar makes mortar more sticky. It adds flexibility and makes it more resistant to water. RDP powder is used in different construction areas, like wall putty, tile adhesive, and plaster.
