How to mix hydrophobic powder with water?

Mixing the hydrophobic powder with water is a straightforward process. Follow these steps for optimal results:


1. Measure the Powder. Start by measuring the required amount of hydrophobic powder based on your specific application.


2. Gradual Mixing. Slowly add the powder to the water, stirring continuously. Adding the powder gradually to prevent clumping and ensure even dispersion is crucial.


3. Stirring. Stir the mixture thoroughly, ensuring the powder is well-distributed. Use a stirring tool to achieve a consistent blend.


4. Allow Settling. After stirring, allow the mixture to settle for a brief period. This enables hydrophobic properties to take effect.


5. Application. Once the mixture is ready, apply it according to your intended use. Hydrophobic properties will provide the desired effect, whether for coatings, treatments, or other applications.

How does hydrophobic powder work?

The hydrophobic powder is quickly dissolved in water. It forms a polymer emulsion to evenly distributes within the mortar system. After cement undergoes hydration, the cement, sand, and polymer emulsion cross-link internally. Thus, forming a waterproof layer can increase the strength of the waterproof membrane layer.


The active ingredients in the hydrophobic powder can seal the fine pores inside the mortar. As a result, it enhances the total water resistance ability. It can be applied to waterproof bathrooms, swimming pools, and exterior walls.


The dosage of hydrophobic powder is proportional to the waterproofing effect. We recommend adjusting the dosage based on specific application needs. You can also consult our experts anytime for guidance on RDP customizing formulations.

Does the slight color variations affect the product's functionality?

Slight color variations in the polymer may occur due to natural manufacturing processes. But, these variations do not impair the functionality of the hydrophobic powder.


WOTAIchem commitments to quality ensures these cosmetic differences have no impact on the properties or performance. You can trust in the consistent and reliable functionality of our product. If you have specific concerns or questions, feel free to contact our customer support for further help.
