Waterproofing chemicals are substances used to make surfaces resistant to water penetration. They are commonly applied in construction to protect buildings, roofs, basements, water tanks, bathrooms, and other structures from water damage, mold growth, and corrosion.
Here’s a detailed breakdown of the types of waterproofing chemicals, their uses, composition, and brands:
🔹 Types of Waterproofing Chemicals 1. Acrylic-Based Waterproofing
Composition: Acrylic polymer emulsions.
Application: Roofs, terraces, exterior walls.
Properties: UV resistant, flexible, good adhesion.
Example Brands: Dr. Fixit Raincoat, SikaCool.
2. Polyurethane-Based Waterproofing
Composition: Single or two-component polyurethane.
Application: Roofs, podium decks, swimming pools.
Properties: Highly elastic, seamless membrane, durable.
Example Brands: Fosroc Nitoproof, BASF MasterSeal.
3. Bituminous Waterproofing (Asphalt-Based)
Types: Bitumen membranes (hot or cold applied), modified bitumen.
Application: Roofs, basements, foundations.
Properties: Economical, good adhesion, not UV resistant (needs protection).
Example Brands: Asian Paints SmartCare, STP ShaliUrethane.
4. Cementitious Waterproofing
Composition: Cement + additives + polymers.
Application: Bathrooms, basements, water tanks, tunnels.
Properties: Easy to apply, good for wet areas, not UV resistant.
Example Brands: Dr. Fixit Pidifin, Kryton Krystol.
5. Crystalline Waterproofing
Composition: Special cementitious compounds with reactive crystals.
Application: Concrete structures, basements, water tanks.
Properties: Reacts with water to form crystals, seals cracks up to 0.4 mm, permanent solution.
Example Brands: Xypex, Penetron, Kryton.
6. Silicone-Based Water Repellents
Composition: Silanes, siloxanes.
Application: Stone, brick, concrete facades.
Properties: Transparent, breathable, water-repellent, UV resistant.
Example Brands: Wacker Silres, Dow Corning.
7. Epoxy-Based Coatings
Composition: Epoxy resins and hardeners.
Application: Industrial floors, chemical plants, water tanks.
Properties: Chemical resistant, tough, good bonding.
Example Brands: Fosroc Nitocote, SikaTop Seal.
