Bondone Silcrete — the primer & sealer that stops epoxy floors from peeling.

Two-part, solvent-free epoxy primer and waterproofing coat from DCM Shriram's Bondone range. Silcrete penetrates concrete, locks out moisture, and gives the topcoat something to hold onto. Mixed at 100:50 by weight with a 55-75 minute pot life, it covers approximately 45 sq.ft per kg at 100 micron thickness. As of September 2026, the 7.5 kg kit is ₹3,610 from our Ghaziabad warehouse — 12 kg, 30 kg, and 200 kg drums also available.

04Applications

Where Silcrete Earns Its Place

Silcrete is a 100:50 solvent-free epoxy with 45 sq.ft/kg coverage and chemical resistance up to 30% sulphuric acid. These are the three jobs it handles best.

Prime before any topcoat

Apply Silcrete first, then Flowtop or any epoxy floor coating. Skipping the primer is the #1 cause of delamination — this is the bond surface.

Basement & tank waterproofing

Cures to a seamless, non-porous barrier that stops water ingress from damp concrete — floors and walls, common in Delhi NCR basements during monsoon.

Chemical bunds & machine grouting

Line cement tanks and ETP plants against acid and alkali attack. Add quartz sand (100:50:500) for high-strength epoxy mortar on heavy machinery.

06Quick Answer

Straight Answers

How much does Bondone Silcrete cost?

₹3,610 per 7.5 kg kit (₹481 per kg), which covers roughly 340 sq.ft as a primer coat. Includes resin and hardener in the correct 100:50 ratio. PAN India shipping from our Ghaziabad warehouse — WhatsApp for stock and bulk rates.

What is the mix ratio of Silcrete?

100:50 by weight (resin to hardener) — mix thoroughly for 2-3 minutes with a digital scale. Pot life is 55-75 minutes at 25°C. For mortar, add quartz sand at 100:50:500.

What is the coverage of Silcrete?

45 sq.ft per kg at 100 micron primer thickness on an ideal concrete surface. The low mix viscosity (2,000-2,500 mPa·s) lets it penetrate the substrate properly.

How much does Silcrete cost per square foot?

Roughly ₹10–₹12 per sq.ft as a primer coat: a 7.5 kg kit (₹3,610) covers about 340 sq.ft of floor. It is the protective underlayer that stops the topcoat from peeling, so adding it upfront saves a full floor replacement later — the highest-ROI coat in a flooring system.

Silcrete or Flowtop — which do I need?

Use Silcrete (primer/waterproofer, tear 100:50) on bare or damp concrete first, then Flowtop (self-levelling topcoat, 2:1) on top. Silcrete alone is a waterproofing coat; floor durability comes from layering both. Skip the primer and a concrete floor will typically delaminate from the epoxy within a year.

08FAQ

Bondone Silcrete Questions — Answered

What is Bondone Silcrete used for?

Bondone Silcrete has two primary uses. First, as an epoxy primer applied beneath floor topcoats like Flowtop — it penetrates concrete, seals the substrate, and prevents delamination. Second, as a standalone waterproofing and chemical-resistant coating for basements, terraces, water tanks, ETP plants, and chemical bunds.

Is Silcrete a primer or a topcoat?

Silcrete is primarily a primer — it goes underneath the topcoat. However, it can also serve as a standalone protective coating in areas where chemical resistance and waterproofing matter more than appearance. It is not a decorative topcoat.

Do I need Silcrete before applying Flowtop?

Yes. Flowtop and any epoxy floor topcoat require a primer for proper adhesion. Skipping the primer is the most common cause of floor delamination. Silcrete penetrates and seals the concrete, creating a bond surface that the topcoat can grip.

What is the mix ratio and pot life of Bondone Silcrete?

The mix ratio is 100:50 by weight (Resin : Hardener). Pot life is 55–75 minutes at 25°C for a 100g mass per ASTM D2471. Always verify against the batch-specific TDS supplied with your order.

What chemicals does Silcrete resist?

Silcrete withstands 30% sulphuric acid, 20% hydrochloric acid, 15% acetic acid, up to 40% sodium hydroxide (NaOH), and common industrial solvents including toluene, xylene, MEK, and acetone at ambient temperatures. Not suitable for concentrated oxidizing acids above 40%.

Can Silcrete be used for basement waterproofing?

Yes. Silcrete cures to a seamless, non-porous barrier that prevents water ingress from damp concrete substrates. It is commonly used for basement floors and walls in Delhi NCR where groundwater seepage is a persistent problem during monsoon.

What is the price of Bondone Silcrete 7.5kg?

The 7.5kg kit of Bondone Silcrete is priced at ₹3,610 (₹481 per kg). Contact us on WhatsApp at +91 8595955752 for stock availability.

How is Silcrete different from Flowtop?

Silcrete is a functional epoxy primer and protective coating designed for substrate penetration, waterproofing, and chemical resistance. Flowtop is a decorative self-levelling epoxy topcoat for high-gloss floor finishes. Silcrete goes underneath; Flowtop goes on top. Most professional flooring jobs use both.
