Kerakoll Cementoresina Gel is a transparent, two-component gel for walls and floors. It seals the Cementoresina cement-resin surface, creating an ideal base for the Microresina Xtreme protective layer. Applied with Trowel 3 transparent trowel. This is the sealing layer of the Cementoresina and Cementoresina Wall systems.

• Sealing-protective layer: seals the porous cement-resin surface, provides an ideal base for the final protective layer
• Part of the system: the fifth/fourth layer of the Cementoresina floor and Cementoresina Wall wall systems
• Transparent application: smoothed as a thin film using Trowel 3 (Kerakoll special transparent trowel) — follows the texture of the previous layer
• Dries quickly: 12–24 hours, then sanding and Microresina Xtreme protective layer can follow
• Two-component: A:B = 2:1 mixing ratio, 30 minutes pot life
• Low VOC: odorless, for indoor use
• Not a protective layer on its own: always requires a Microresina Xtreme topcoat above

Frequently asked questions

What is Cementoresina Gel for?
Sealing-protective layer in Cementoresina microcement systems. It seals the porous cement-resin surface and creates an ideal base for the Microresina Xtreme protective layer. Without it, the protective layer does not adhere properly.

Is the Gel mandatory in the microcement system?
Yes. The 5th and 4th layers of the Cementoresina floor and Cementoresina Wall systems respectively. Without the Gel, the Microresina Xtreme protective layer does not adhere properly to the cement-resin surface.

Is the Gel waterproof?
No. The Gel is a sealing-protective layer but NOT waterproof. Waterproofing is provided by the Microresina Xtreme protective layer. For showers and next to bathtubs, the full system is required for waterproofing.

How many layers are needed in the Cementoresina microcement system?
Floor: 6 layers (primer, leveling, 2× texture, Gel, protective layer). Wall: 5 layers (primer, leveling, texture, Gel, protective layer). Cementoresina Gel is part of every system.

How much Gel is needed per square meter?
About 80 g/m². A 0.6 kg package (0.4 kg A + 0.2 kg B) covers approx. 7 m².

How long does it take to dry?
After 12 hours (+30°C) or 24 hours (+15°C) drying, sanding and applying the Microresina Xtreme protective layer is possible.

Can I apply it myself?
Technically yes, but not recommended. 30 minutes pot life, precise 2:1 mixing ratio, special Trowel 3 transparent spatula required. The texture of the previous layer must be followed. Cementoresina systems require professional application.

Why is the Gel transparent?
So it does not change the texture and color of Cementoresina. The Gel only seals and prepares for the protective layer — it does not cover or color.

What happens if I apply it too thickly?
The material accumulates, whitens, and causes visible defects. It must be applied as a thin film with the Trowel 3 spatula, exactly 80 g/m² thick.
