Sika® Rustop

Two-component cement-bound coating that seals reinforcement and concrete from water, chlorides and CO2

Product Overview

Sika® Rustop is a cement-bound, synthetic-resin-modified two-component coating that protects reinforcement and concrete from corrosion. Applied over steel, it forms an impervious anti-corrosive layer that blocks the ingress of water, chlorides and carbon dioxide, and it contains corrosion inhibitors for added protection. Because the system is cementitious, it bonds strongly to steel, concrete and mortar and provides a sound key for subsequently placed concrete or repair mortars. It is ideal for reinforcement with insufficient cover or in thin sections, for embedded steel in structures being rehabilitated, and for protecting concrete against calcium chlorides and de-icing salts. Repair contractors and structural engineers across India use it as a dependable rebar primer. Space Arc Engineering, an authorized Sika distributor, supplies it in pre-batched 1.25 kg sets. It mixes 1:4 by weight and accepts concreting after 24 hours.

Features & Benefits

  • Contains corrosion inhibitors for additional reinforcement protection
  • Cementitious base bonds strongly to steel, concrete and mortar
  • Provides a sound key for subsequent concrete or repair mortar
  • Protects concrete against calcium chlorides and de-icing salts
  • Pre-batched two-part packs make on-site mixing straightforward

Frequently Asked Questions

What does Sika Rustop protect against?

It forms an impervious anti-corrosive coating on reinforcement and concrete that blocks water, chlorides and carbon dioxide, and it contains corrosion inhibitors. It also protects concrete against calcium chlorides and de-icing salts.

Will repair mortar bond to Sika Rustop?

Yes. Because the coating is cement-bound, it offers good bonding for subsequently applied concrete or repair mortars, making it well suited to repair systems.

How is Sika Rustop mixed and applied?

Mix Part A and Part B at 1:4 by weight and apply within 20–30 minutes, with a second coat after 2–3 hours. Concreting can follow after 24 hours. Refer to the TDS for full guidance.

What is the coverage of Sika Rustop?

On average about 3.6–4 kg/m² for two coats, or roughly 3–4 sq ft per 1.25 kg pack in two coats, depending on the reinforcement diameter.
