Waterproof Better. Build Stronger.

WaterSeal Multipurpose Polymer is a premium 55% solid-content SBR latex polymer specially developed to improve the waterproofing, strength and durability of cement-based mortars and screeds. It converts ordinary cement mortar into a highly water-resistant, flexible and long-lasting construction material, making it ideal for waterproofing terraces, bathrooms, balconies, water tanks and other moisture-prone areas.

Designed as an all-round construction polymer, it enhances bonding, reduces water absorption, minimizes shrinkage cracks and significantly improves the overall performance of cementitious applications.

How to Prepare & Use

Step 1 – Surface Preparation

Remove dust, loose particles, oil, grease and weak material. Ensure the surface is structurally sound and lightly damp before application.

Step 2 – Prepare the Polymer Solution

Mix 1 part WaterSeal Multipurpose Polymer with 5 parts clean water until uniform.

Step 3 – Prepare the Mortar

Gradually add the polymer solution into the cement-based mix while stirring continuously to achieve a smooth, lump-free consistency.

Step 4 – Application

Apply the prepared mortar or slurry uniformly using a brush, trowel or suitable application tool depending on the application.

Step 5 – Curing

Protect the treated surface and cure properly to achieve optimum waterproofing and long-term durability.
