Why is Smart Screed Necessary?

Smart screed prevents cracking, breaking, and deformation of covering materials (ceramic, laminate, parquet) on uneven floors. It extends the life of the covering by providing floor flatness, increases installation quality, and provides an aesthetic appearance. It is mandatory especially on floors with height differences of more than 3 mm over a 2-meter straightedge.

What is the Drying Time of Smart Screed?

Smart screed becomes walkable in 4-6 hours under normal conditions, and coverings can be applied after 24 hours. It reaches full strength in 7-10 days. Drying time may vary depending on room temperature, humidity, and screed thickness. With special fast-drying formulas, coverings can be applied in 12 hours.

What Should the Smart Screed Thickness Be?

Smart screed can be applied with a minimum thickness of 3 mm and a maximum of 30 mm. The ideal thickness is between 5-10 mm. For deep pits and high unevenness, it is recommended to first level with coarse screed and then apply a thin layer of smart screed. There is a risk of cracking in very thin applications.

Which Coverings Can Be Applied After Smart Screed?

Ceramic, porcelain, laminate parquet, laminated parquet, solid parquet, PVC flooring, vinyl, carpet, and rubber floor coverings can be safely applied on smart screed. Covering work should start after the screed is completely dry (at least 24 hours).

Where are Smart Screed Application Areas?

Smart screed is used in residences (houses, apartments, villas), offices, stores, schools, hospitals, and industrial facilities. It can be applied on different floor types such as concrete, old ceramic, wood, and marble. It is also safely applied on underfloor heating systems.

What is the Difference Between Smart Screed and Traditional Screed?

Traditional screed requires manual leveling, has a drying time of 28 days, and is applied thick. Smart screed, on the other hand, self-levels automatically, is ready for covering in 24 hours, is applied in thin layers, and creates a more homogeneous surface. Labor cost is lower.

Does Smart Screed Crack?

When professional application and quality materials are used, smart screed does not crack. To prevent cracking risk; floor preparation (dust, oil, dirt cleaning), primer application, appropriate thickness (min 3 mm), and correct water/mix ratio are critical. Expansion joints are left to create expansion allowance.

Smart Screed Application | Self-Leveling | Floor Leveling

Smooth floor surface after smart screed application - Self levelling screed

What is Smart Screed (Self-Levelling Screed)?

Smart screed (self-spreading screed) is a high-performance floor preparation and finishing material with self-leveling properties, used in a wide range from residences to industrial facilities, offices to commercial areas. These self levelling screed systems, applied in fluid consistency, stand out with superior features that meet the fast, flat, and smooth floor preparation needs of modern structures.

Smart Screed Chemical Composition and Material Types

Cement-Based Smart Screed (Cementitious Self-Levelling)

The most commonly used type of smart screed, with Portland cement as its main component.

Components: Fine aggregate (quartz sand), fluidizers, set regulators
Water/Cement Ratio: 0.4-0.5
Compressive Strength: 20-35 MPa
Drying Time: 24-48 hours, full cure 28 days
Advantages: Economical, suitable for all floor types

Calcium Sulfate (Anhydrite) Based Smart Screed

Anhydrite screed, a premium self levelling screed type, is widely used in Europe.

Main Component: Anhydrous calcium sulfate
Advantages: Excellent flatness, low shrinkage, superior acoustic properties
Limitations: Not used in wet areas
Cost: 30-50% higher than cement screed
Drying: 7-14 days, 3-5 days with fast dryer

Smart Screed Additives and Functions

Fluidizers: Provide high fluidity, give self-spreading property
Set Regulators: Control application time and hardening speed
Air Entrainers: Increase workability, enhance freeze-thaw resistance
Polymer Additives: Provide flexibility, reduce cracking risk
Fiber Reinforcements: Increase crack resistance, prevent shrinkage cracks

Advantages of Smart Screed System

Perfect Flatness and Level

Smart screed self-levels with gravity to create a perfectly flat surface. Minimizes human error margin in traditional screeds. Flatness tolerance reaches SR1-SR2 class (DIN 18202).

Fast Application and Time Saving

While 100 m² area takes 1-2 days with traditional screed, it is completed in 2-3 hours with self levelling screed. Labor cost decreases by 50-70%.

Minimum Labor Requirement

Does not require experienced screed masters. Applied with pump operator and assistants. Does not require special training.

Thin Layer Applicability

Can be applied in very thin layers like 1-3 mm. Minimizes ceiling height loss in existing structures.

High Strength and Durability

Provides 20-35 MPa compressive strength thanks to optimized water/binder ratio. Long-lasting and wear-resistant.

Smart Screed Types and Applications

Thin Layer Smart Screed

1-10 mm thickness, used for surface correction. Prepares ideal surface before final flooring. Fast drying time (6-24 hours).

Medium Thickness Smart Screed (Standard)

10-40 mm thickness, general purpose use. Ideal solution for underfloor heating systems. Provides structural strength (20-30 MPa).

Thick Layer Smart Screed (Heavy Duty)

40-100 mm thickness, for industrial facilities. Resistant to forklift and heavy machine traffic. Compressive strength 30-50 MPa.

Smart Screed for Underfloor Heating Systems

High thermal conductivity (λ = 1.2-1.4 W/mK), low shrinkage. Perfectly fills gaps between pipes.

Smart Screed Usage Areas

Residential Applications

Living rooms and lounges (floor preparation)
Kitchens (waterproof type)
All underfloor heated areas
Balconies and terraces (outdoor type)
Apartment renovations

Commercial Areas

Offices and business centers
Shopping malls
Hotel rooms and lobbies
Restaurants and cafes
Showrooms and exhibition areas

Healthcare Facilities

Hospital rooms and corridors
Operating rooms and intensive care units
Laboratories and imaging departments
Pharmacies and drug preparation rooms

Smart Screed Application Process

1. Project Planning and Preparation

Area measurement, floor assessment, screed thickness calculation, material type selection. Optimal temperature 10-25°C.

2. Subfloor Preparation

Cleaning: Removal of dust, dirt, oil residues
Repair: Repair of cracks and cavities
Drying: Moisture content should be below 4% RH
Absorption Control: Primer application when needed

3. Primer Application

Reduces floor absorbency, increases bonding strength. Provides homogeneous drying. 2-12 hours drying time.

4. Material Preparation and Mixing

Use of factory-packaged dry mix
Precise measurement of water amount
Homogeneous mixing with industrial mixer
Fluidity test (24-28 cm spread)

5. Screed Pouring and Leveling

Start pouring from the farthest point
Self-spreading
Removing air bubbles with spike roller
Thickness control

6. Curing Process

The first 24 hours are critical:

Area closed to traffic
Air flow should be prevented
Temperature between 10-25°C
Humidity 50-70%

Smart Screed Maintenance and Long-Term Performance

Smart screed requires minimal maintenance after application and covering:

Avoiding early traffic
Proper temperature and humidity control
Regular ventilation
Professional covering application

Smart Screed Prices
