KYK MegaZemin Z101 | Cement-Based Self-Leveling Floor Screed

Product Description

KYK MegaZemin Z101 is a cement-based, self-leveling floor screed enhanced with special additives to provide smooth application and superior surface quality.

Its free-flowing formulation creates a flat, homogeneous, and durable surface with minimal effort. The product is compatible with underfloor heating systems and is suitable for correcting floor irregularities from 3–10 mm in a single application. For thicker applications between 10–30 mm, dry aggregate can be added to the mix.

With excellent adhesion, crack resistance, and easy application, KYK MegaZemin Z101 delivers long-lasting performance for residential, commercial, and industrial flooring projects.

Application Areas

KYK MegaZemin Z101 is suitable for various floor preparation applications, including:

Leveling cement-based and concrete substrates
Applications over underfloor heating systems
Surface preparation before ceramic, PVC, parquet, carpet, and other floor coverings
Creating smooth walking surfaces in pedestrian traffic areas
Repairing floor irregularities between 3–10 mm
Correcting uneven surfaces up to 30 mm with the addition of dry aggregate

It provides an ideal substrate for both residential and commercial flooring installations.

Application Instructions

Surface Preparation

Proper substrate preparation is essential for optimum performance.

The surface must be dry, clean, and free from dust.
Remove oil, grease, dirt, and loose cement residues.
On exposed concrete surfaces, apply MegaFilm BB A204 primer.
On cement-based substrates, use MegaFilm A201 or MegaFilm A901 primer.
Turn off underfloor heating systems at least 24 hours before application.

Mixing and Application

Mix one 25 kg bag with 4.0–4.25 liters of clean water.
When using dry aggregate, reduce the water ratio to approximately 15%.
Mix with a low-speed mixer for 3–4 minutes, allow the mixture to rest for 1–2 minutes, then remix briefly.
Apply the material within 15 minutes after mixing.
Standard application thickness is 3–10 mm.
For applications between 10–30 mm, add 0–4 mm dry aggregate.
Use a spiked roller and spiked shoes to eliminate trapped air bubbles and ensure a smooth finish.

Drying Times

Stage	Time
Pot life	Approximately 15 minutes
Foot traffic (10 mm thickness)	Approximately 24 hours
Installation of parquet or PVC flooring	Approximately 24 hours
Underfloor heating commissioning	Minimum 7 days

Application Recommendations

Protect the surface from wind, direct sunlight, and water during curing.
In hot weather, avoid direct sunlight and use cool water for mixing if necessary.
Apply in sections of approximately 4 × 4 meters to minimize shrinkage cracking.
Deep substrate defects should be repaired with MegaTamir Grout T105 before leveling.
Do not add cement, lime, gypsum, or other foreign materials to the product.

Estimated Consumption

Thickness	Average Consumption
10 mm	19–21 kg/m²
30 mm	Approximately 60 kg/m²
100 mm	Approximately 200 kg/m²

Consumption may vary depending on substrate absorbency and site conditions.

Frequently Asked Questions (FAQ)

What is KYK MegaZemin Z101?

KYK MegaZemin Z101 is a cement-based, self-leveling floor screed designed to produce smooth, durable, and high-quality floor surfaces.

Where can it be used?

It is suitable for interior concrete and cement-based floors, underfloor heating systems, and surface preparation before installing ceramic tiles, PVC, parquet, carpet, and similar floor coverings.

What application thickness is recommended?

The product can be applied directly between 3–10 mm. With the addition of dry aggregate, applications up to 30 mm are possible.

What is its compressive strength?

The product provides a compressive strength of ≥25 N/mm² and a flexural strength of ≥6 N/mm².

How long does it take before the floor can be walked on?

At a thickness of approximately 10 mm, the surface is typically ready for foot traffic after 24 hours.

Is it compatible with underfloor heating?

Yes. Underfloor heating systems can be recommissioned after a minimum curing period of 7 days.
