SBR Waterproofing Chemical In Dehradun
Details of SBR Waterproofing Chemical
What is SBR Waterproofing Chemical?
SBR stands for Styrene-Butadiene Rubber, a synthetic rubber polymer widely used in construction as a waterproofing additive. SBR waterproofing chemicals are polymer-based liquids or powders that enhance the water resistance and durability of cementitious materials.
Composition
Styrene-Butadiene Rubber latex or polymer emulsion
Water as solvent/carrier
Sometimes additives like stabilizers, plasticizers, and anti-foaming agents
How SBR Waterproofing Works
When added to cement, mortar, or concrete mixes, SBR polymers form a flexible, elastic film within the matrix.
This film reduces porosity and micro-cracks, thus preventing water penetration.
The polymer also improves adhesion, flexibility, and durability.
It forms a continuous barrier against moisture ingress.
Forms Available
Liquid Emulsion: Commonly used, easy to mix with cement or plaster.
Powder Form: Requires mixing with water before adding to cement.
Applications
Waterproofing of roofs, terraces, balconies, and bathrooms.
Protection of water tanks, reservoirs, and swimming pools.
Waterproofing basements and retaining walls.
Repairing cracks and leaks in concrete structures.
Adhesive bonding in tile fixing.
Benefits
Improves tensile strength and flexibility of cementitious mixes.
Reduces permeability to water and salts.
Enhances resistance to alkalis, acids, and chemicals.
Provides elasticity to withstand structural movement.
Easy to apply and mix with cement or mortar.
Improves adhesion of plaster to substrates.
Typical Usage Instructions
Mix SBR liquid with water or directly with cementitious mix as per manufacturer ratio (usually 1:4 to 1:6 by volume for cement).
Apply as a slurry coat on the surface or integrate into the mortar.
Allow to cure properly for best results.
Ensure substrate is clean and free from dust/oil.
Important Notes
Not a standalone waterproof coating—used as an additive or primer.
Usually requires a protective layer or final coating.
Curing time may vary based on ambient temperature and humidity.
Check compatibility with other construction materials.
