Self-Leveling PU Sports Flooring System for Smooth, Seamless & Professional Sports Surfaces
Sport Floor manufactures and supplies Self-Leveling PU Sports Flooring System materials for projects that require a dense, smooth and continuous polyurethane sports surface built over a compatible prepared substrate or resilient base.
The self-leveling polyurethane layer is the dense body of many seamless sports-flooring systems. It flows and levels during application, helping create a uniform surface above the correctly prepared lower layers before the final top coat and sports markings are applied.
Sport Floor manufactures its own polyurethane sports-flooring products and supplies them directly for local and international projects. German raw materials are used within applicable Sport Floor PU formulations, giving professional buyers one coordinated material route from primer and pore sealer through self-leveling PU, top coat and line marking.

What is a self-leveling PU sports floor?
A liquid-applied polyurethane layer that forms the dense seamless body of the sports surface
Self-leveling polyurethane is used in sports-floor systems because it can be spread over a properly prepared base and form a continuous, dense layer without the sheet joints associated with rolls or tiles.
The material is not used in isolation. Depending on the system, it may be installed over a primed rigid substrate, a prefabricated resilient mat, an in-situ rubber cushion, a rubberized PU base or another compatible sports-floor underlayer.
Where the lower layer is porous, a pore sealer is normally used first. The self-leveling PU then creates the smooth dense surface that receives the final protective and functional top coat.
Dense seamless polyurethane layer for professional sports-floor build-ups.
Can be used above rigid or resilient lower layers depending on system design.
Pore sealer prepares compatible porous bases before dense PU application.
Top coat completes the final functional surface above the self-leveling layer.

Where it sits in the system
Primer / resilient base → pore sealer → self-leveling PU → top coat → markings
Close Porosity
Use compatible pore sealer when the lower layer is porous or rubberized.
Apply Self-Leveling PU
Spread the polyurethane compound to create the dense continuous sports layer.
Finish the Surface
Apply compatible top coat and sports markings after the correct cure interval.
Application control
Good self-leveling requires correct substrate preparation, flow and de-aeration
A self-leveling product cannot correct major substrate defects by itself. The base should first be prepared to the required flatness and condition. Cracks, joints, moisture and weak areas should be resolved before the dense PU layer is installed.
During application, the material should be mixed and spread within its current working limits. Suitable tools help control thickness, leveling and de-aeration so the surface cures as a continuous polyurethane layer.
Exact mixing ratio, working time, consumption, layer thickness, application temperature and recoating interval are product-specific and should come from the current Sport Floor TDS.
Flow does not replace substrate preparationSelf-leveling PU creates a uniform dense layer only when the lower surface is correctly prepared and compatible.
Do not confuse system components
Self-Leveling PU is neither the primer, the pore sealer nor the final top coat
Primer prepares the substrate interface. Pore sealer closes porous resilient or rubberized layers. Self-leveling PU creates the dense seamless polyurethane body. Top coat provides the final exposed functional finish.
Separating these roles is important when specifying materials or preparing a BOQ. Replacing one function with another can cause poor bonding, surface defects or incorrect finished performance.
Sport Floor manufactures dedicated products for these different functions, allowing contractors to source coordinated materials from one product family rather than mixing unrelated chemistries.

Why use a self-leveling PU layer?
The value is in continuity, density and controlled surface formation
Seamless Surface
Creates a continuous polyurethane layer without sheet or tile joints.
Surface Uniformity
Flow and leveling help create a consistent dense layer over the correctly prepared base.
System Versatility
Can be used in rigid, cushioned, indoor and compatible outdoor PU sports-floor systems.

Common specification mistakes
Self-leveling does not mean the material fixes every substrate problem automatically
Skipping Pore Sealer
Porous resilient bases normally require correct sealing before dense PU is installed.
Using It as a Top Coat
The self-leveling layer is generally below the final functional finish.
Ignoring Substrate Flatness
Major level problems should be corrected before sports-floor coating.
Copying Competitor Mix Ratios
Mix ratio and working time are formulation-specific and must come from Sport Floor documentation.
Wrong Top Coat
Indoor and outdoor exposure may require different final finishing routes.

Self-Leveling PU Sports Flooring FAQ
Questions contractors and buyers ask before specifying the dense PU layer
What is a self-leveling PU sports flooring system?
It is a seamless sports-floor build-up in which a self-leveling polyurethane compound forms the dense continuous layer beneath the final top coat and sports markings.
Is self-leveling PU the same as a top coat?
No. The self-leveling compound creates the dense body of the surface. The top coat is the final exposed functional finish above it.
Do I need a pore sealer?
If the lower layer is porous, such as a rubber mat or rubberized cushion, the selected system will typically require a compatible pore-sealing step before dense PU application.
Can self-leveling PU be installed over a cushion layer?
Yes, where the complete system is designed for that resilient base and the compatible pore-sealing and bonding stages are used.
Can it be used without a cushion layer?
Some systems may use self-leveling PU over prepared rigid substrates or other approved bases. The exact build-up should follow the selected system.
Does Sport Floor manufacture the self-leveling material?
Yes. Sport Floor manufactures PU Self-Leveling Compound and related sports-flooring polyurethane products.
Does Sport Floor use German raw materials?
Yes. German raw materials are used within applicable Sport Floor polyurethane formulations.
Can it be used outdoors?
Compatible outdoor PU systems can use a self-leveling layer beneath exterior UV-resistant finishing products. Outdoor application should follow the specific system and product documentation.
What thickness should I specify?
Thickness is project- and system-specific. Use current Sport Floor technical documentation or the approved project specification rather than a generic value.
Can Sport Floor supply all related materials?
Yes. A coordinated quotation can include primer, adhesive, resilient base products, pore sealer, self-leveling PU, top coat and line marking.
Can Sport Floor export self-leveling PU materials?
Yes. International contractors, distributors, importers and project buyers can request direct B2B supply at info@sportfloor-m.com.
Can I request TDS and SDS?
Yes. Request current technical documentation for the exact products included in your proposed system.
