Your contractor mentioned Fosroc Brushbond. You Googled it and found very little in plain language. Here's everything you need to know as a Bangalore homeowner — what it is, what it does, and whether it's the right product for your situation.
What is Fosroc Brushbond TG?
Fosroc Brushbond TG is a polymer-modified, flexible cementitious waterproofing coating made by Fosroc International. The "TG" stands for Two-Grade — it comes as a two-component system (powder + liquid) that are mixed on site before application.
It is applied by brush or roller in two coats, typically at a total thickness of 1.5–2mm. Once cured, it forms a seamless, flexible waterproof membrane that bonds directly to concrete and masonry substrates.
What Makes Brushbond Different from Standard Waterproofing?
| Property | Fosroc Brushbond TG | Standard cementitious coating |
|---|---|---|
| Flexibility | High — bridges cracks up to 1.5mm | Low — rigid, cracks with movement |
| Bond strength | Very high (polymer-modified) | Moderate |
| Application method | Brush/roller — contractor-friendly | Brush/roller |
| Curing time | 24 hours per coat | 12-24 hours |
| Warranty (application) | 7-10 years | 5-7 years |
| Cost (installed) | ₹55–₹70/sq ft | ₹35–₹55/sq ft |
When is Fosroc Brushbond the Right Choice?
Use Brushbond when:
- Building is 10+ years old with visible structural cracks — Brushbond's crack-bridging ability handles building movement that rigid coatings can't
- Terrace has had repeated waterproofing failures — If two previous treatments failed, flexibility matters more than cost
- High water pressure situations — Basements, underground sumps, water-retaining structures
- Commercial or premium residential projects — Where a longer warranty and documented specification is required
- External walls with thermal movement — Brushbond handles expansion-contraction cycles better than standard coatings
Dr. Fixit Newcoat is sufficient when:
- Building is less than 10 years old
- Terrace has no visible structural cracks
- First-time waterproofing on a relatively new building
- Budget is a primary consideration

Fosroc Brushbond — Questions Answered
Yes — through authorised Fosroc dealers in Bangalore. It's not available at regular hardware stores. LoklFix sources Fosroc products directly from authorised dealers and provides batch numbers for warranty registration.
Minimum two coats, applied 24 hours apart. Total thickness should be 1.5–2mm. Under-application is the most common reason waterproofing fails prematurely — always verify the contractor is applying the minimum thickness specified.
Sometimes — if the existing layer is intact and well-bonded. If the existing waterproofing is blistering or delaminated, it must be removed first. Our inspection will assess this before quoting.
