SBR Latex Price List Bangalore vs Other Waterproofing Agents: Which to Use
Summary
- The most common waterproofing mistake is choosing the wrong product. Use integral compounds for new concrete, SBR latex to enhance repair mortars, and 2K coatings for sealing critical surfaces like terraces.
- For new construction, adding an integral waterproofing compound to the concrete mix is the most economical way to achieve permanent, built-in protection.
- To fix leaks on an existing terrace or in a bathroom, applying a 2K coating is the correct solution as it forms a tough, flexible membrane over the surface.
- Once you've chosen the right product, get genuine Dr. Fixit waterproofing materials delivered to your Bangalore site in 60 minutes with HomeRun.
You've just discovered a damp patch spreading across your ceiling, or your newly constructed slab has already started showing seepage. Sound familiar? If you're a homeowner or contractor in Bangalore, you're not alone.

Decoding the "Big Three" in Chemical Waterproofing
Before we get to prices and comparisons, let's establish what each product actually does. Picking the wrong type — not just the wrong brand — is the most common (and costly) mistake in waterproofing.
1. SBR Latex — The Versatile Repair & Bonding Specialist
SBR (Styrene Butadiene Rubber) latex is a high-performance synthetic rubber bonding agent that dramatically enhances the water resistance, flexibility, and adhesion of cement-based mortars. Think of it as a performance booster for your regular cement mix.
When you mix SBR latex into a mortar, it reduces water permeability and creates a stronger bond between surfaces — particularly between old and new concrete. It also increases the tensile strength and abrasion resistance of the resulting layer.
Best for: Repair mortars, crack filling, bonding agent between old and new plaster, screed additive for wet areas like bathrooms and balconies.
2. Integral Waterproofing Compound — Built-In Protection from Day One
An integral waterproofing compound is a liquid chemical admixture added directly to the concrete or mortar batch during mixing, making the entire mass resistant to moisture from the inside out. This is the foundation of what professionals call "preventive waterproofing."
These compounds work in one of three ways: as a densifier (fills capillary pores), a repellent (creates a hydrophobic polymer barrier), or a crystalline admixture (grows crystals that seal pores and self-heal microcracks up to 0.5mm). Dr. Fixit 101 Pidiproof LW+ belongs to this category.
Best for: New RCC construction — foundations, columns, roof slabs, beams, basements, and sumps. Because it becomes part of the concrete itself, it can't be torn, punctured, or damaged during backfilling. It's permanent.
3. 2K Waterproofing Coating — The Heavy-Duty Surface Shield
A 2K (two-component) waterproofing coating is exactly what it sounds like: a permanently flexible, cement-modified membrane formed by combining a liquid component and a powder component. Once cured, it creates a seamless, tough barrier over the substrate that can handle direct water pressure and bridge minor cracks.
Unlike integral compounds, 2K coatings are applied to the surface rather than mixed into the structure. This makes them ideal for both new construction and renovation projects.
Best for: Terraces, roofs, podium slabs, bathrooms, water tanks, and basements — any surface subject to sustained water contact or hydrostatic pressure.

| Can Be Used on Existing Structures? | ✅ Yes | ❌ No (must be added during concrete mixing) | ✅ Yes |
| Flexibility of Membrane | Low — inherits the rigidity of cured mortar | N/A — becomes part of the concrete mass | High — permanently flexible, bridges minor cracks |
Reading the Table: The Key Insight
Notice that the integral compound is the most economical option per litre, but it's only useful in new construction. If you're trying to fix an existing terrace leak, it won't help you at all.
The SBR latex sits at a mid-range price point and is your go-to for bonding and repair work — an incredibly versatile product, but it's not designed to serve as a standalone primary waterproof membrane on a terrace or water tank.
The 2K coating is the premium choice, but it earns its price on terraces and water tanks where nothing less than a proper membrane will do. Using a cheaper solution in these locations often means redoing the entire job in 2–3 years.
Step-by-Step Application Guide
How to Use SBR Latex (Dr. Fixit 301 Pidicrete URP)
- Surface Prep: Thoroughly clean the surface. Remove all dust, grease, oil, and loose particles. For repair work, open up cracks properly rather than sealing over them.
- Mixing: Dilute SBR latex with water or mix directly into the cement mortar at the application's recommended ratio (typically 1 part SBR : 1–1.5 parts water for a bond coat, or add to mortar as a percentage replacement of mixing water).
- Application: Apply the neat slurry as a bond coat first; while tacky, apply the modified mortar or screed over it.
- Curing: Allow proper curing before applying subsequent layers. Keep the surface moist for at least 3 days.
How to Use Integral Compound (Dr. Fixit 101 Pidiproof LW+)
- Dosage: Use 200 ml of Dr. Fixit 101 Pidiproof LW+ for every 50 kg bag of cement — this precision is important.
- Mixing: Add the measured liquid to the gauging water (the water used for batching the concrete).
- Combine: Pour the water-admixture solution over the dry cement-sand-aggregate mix. Mix thoroughly for 2–3 minutes until uniform.
- Pour & Cure: Place and cure the concrete as per standard construction practice. The protection is now built in permanently.
How to Use 2K Coating (Dr. Fixit 112 Pidifin 2K)
- Surface Prep (Critical): Clean the surface completely — no loose material, no oil, no standing water. Fill all cracks and honeycombs with Dr. Fixit 201 Crack-X Paste before starting.
- Pre-Wetting: Saturate the substrate with clean water until it reaches a "saturated surface dry" (SSD) condition — damp but not puddle-wet.
- Mixing: Slowly add the powder component into the liquid component while continuously stirring with a slow-speed mixer until you get a smooth, lump-free slurry.
- First Coat: Apply evenly using a stiff brush in a single, consistent direction.
- Drying: Allow the first coat to cure for 4–6 hours.
- Second Coat: Apply in a direction perpendicular to the first coat for complete coverage.
- Final Curing: Allow to air-cure for 7 days. Protect from direct sunlight and rain during this period.

Frequently Asked Questions
What is the main difference between Dr. Fixit 301, 101, and 112?
The main difference lies in their application and purpose. Dr. Fixit 101 is an integral compound mixed into new concrete, Dr. Fixit 301 is a bonding agent and additive for repair mortars, and Dr. Fixit 112 is a heavy-duty coating applied onto a surface. Each is designed for a specific stage and type of waterproofing need.
Which waterproofing is best for a new house construction?
For new construction, an integral waterproofing compound like Dr. Fixit 101 Pidiproof LW+ is the best initial choice for all RCC structures (foundations, columns, slabs). This makes the concrete itself water-resistant from day one. For critical areas like the terrace or water tanks, a 2K coating like Dr. Fixit 112 Pidifin 2K should be applied as a surface membrane after the structure cures.
How do I fix a leak in my existing terrace?
To fix a leak in an existing terrace, the most effective solution is a 2K waterproofing coating like Dr. Fixit 112 Pidifin 2K. This creates a seamless, flexible membrane over the entire surface. Before application, it is crucial to properly clean the surface and repair all visible cracks, often using a mortar modified with SBR Latex (Dr. Fixit 301).
Can I use SBR Latex (Dr. Fixit 301) alone for terrace waterproofing?
No, SBR Latex is not a standalone waterproofing solution for a terrace. It is a bonding agent and mortar modifier designed to enhance repairs and screeds. While it improves water resistance, it does not form the continuous, flexible membrane required to withstand constant water exposure on a terrace. A 2K coating is the correct product for this application.
Why is 2K coating more expensive than other waterproofing chemicals?
A 2K coating is more expensive because it is a high-performance, two-component system that creates a thick, robust, and flexible membrane. Its formulation is designed to withstand direct hydrostatic pressure, bridge minor cracks, and offer long-term durability in critical areas. The higher price reflects its superior performance and the extensive protection it provides against costly structural damage.
How long does Dr. Fixit waterproofing last?
The lifespan varies by product and application quality. Integral waterproofing (Dr. Fixit 101) is permanent and lasts for the lifetime of the structure. A professionally applied 2K coating (Dr. Fixit 112) can last for over 8-10 years. The longevity of SBR Latex (Dr. Fixit 301) is tied to the durability of the repair mortar it is mixed into.
Stop Leaks — Not Your Project
There's no single "best" waterproofing product, and you can see the full range of options in our complete waterproofing price list. The right answer depends entirely on your situation:
