cement-based self-levelling floor screed with the gel technology

• for levelling old substrates in a layer of 3 - 60 mm
• for making self-levelling floating screeds with a thickness of 30 – 60 mm
• it can be used for making of heating screeds from 25 mm above the heating system (below the standard thickness),
• as substrate for tiles, laminate flooring, fitted carpets, parquet floors and floorboards
• can be used as a final layer - floor
• foot traffic after only 2 hours
• ready for tiling after only 16 hours
• very smooth surface

Designed to address substrate imperfections from minor spot corrections to comprehensive room-wide levelling across 3–60mm applications. Ideal for commercial and residential settings including offices, educational facilities, and residential units where fitted carpets demand precise surface preparation. Delivers the flatness necessary for PVC sheeting, roll coverings, and resin-based finishes.

Raising of the floor level in the whole room - e.g. in order to level two adjacent rooms.

It can be used in residential rooms, hallways, halls, living rooms, offices, public buildings, service facilities, etc.

It can be applied in rooms with increased humidity including bathrooms.

Recommended for levelling old heating, cement and anhydrite screeds - when an uneven screed makes it impossible to install the final cladding and an additional, thin layer of screed must be applied.

Types of finishing coats – tiles, PVC and carpet coverings, wood-based panels, laminated floorboards, PVC panels, epoxy and polyurethane resin varnished floors, parquet, epoxy floors.

TECHNOLOGIES

GEL TECHNOLOGY – UNIVERSAL
Controlled flowability

The gel technology improves processing properties to enable the adjustment of the consistency and flowability of the product to specific application areas. The technology also enables shaping strength parameters and applying them to specific service loads.
In particular:
- it optimizes the cement hydration process and the strength increase rate to limit shrinkage and minimize the risk of cracks,
- large applicability range of mixing water - to adjust the flowability of the screed to the needs and conditions and shape the strength parameters:
• C35F9 A9 – for mixing water 16-17% (4.00- 4.25 l/25 kg)
• C25F7 A12 – for mixing water 18-21% (4.50- 5.25 l/25 kg)
- increased work safety - by accumulating water, it protects the mix in the first phase of binding against too rapid loss of moisture due to sorption by the substrate or evaporation.

EASY MIXING – FLOWING – DE-AERATION

Easy mixing – the wetting additives used shorten the mix preparation time by up to 2-3 times.

Excellent flowability supports the self-levelling of the mix - the addition of plasticizers improves the flow of the mix to enable its quick spreading. ATLAS SMS 60 ULTRA features the ability to easily self-level to minimize the amount of work.

Much faster de-aeration of the screed after pouring (after just 1-2 roller passes) - the formula reduces the amount of air enclosed in the mix to support the self-de-aeration process

SPEED

Acceleration of the initial setting begins after approx. 50 minutes from pouring the screed. Light foot traffic is possible already after 2 hours from pouring the screed, in the full range of permissible thicknesses, and the operational load strength is achieved after 2.5 hours.
Work can be continued after only 16 hours from pouring the screed.

• ATLAS SMS 60 is a gel, fast-setting, self-levelling floor screed with versatile applications, perfect for various floor construction variants and underfloor heating systems. It can also be used as a stand-alone floor.

Cement-based dry mix that flows smoothly to create level surfaces across large areas without rails or boards. Sets quickly—foot traffic possible after 2 hours. Applies by hand or machine pump for efficient coverage. Minimal shrinkage (≤0.6mm/m) prevents cracking and adhesion failure on poor substrates.
