Acoustic Resin Flooring System DECORATIVE. DURABLE. PEACEFUL.
A multi-layer polyurethane resin flooring system with integrated acoustic underlay, engineered to reduce impact sound transmission through floor structures. Seamless, hard-wearing, and available in the full RAL colour range, the definitive specification for resin flooring in multi-storey residential, commercial, and mixed-use buildings where acoustic performance is a design or regulatory requirement.

What is acoustic resin flooring?
The Arturo Acoustic Resin Floor is a six-layer polyurethane resin flooring system that combines the seamless, hygienic performance of conventional self-smoothing resin floor with certified acoustic and thermal insulation properties. The system's acoustic performance derives from a bonded resilient underlay UZIN RR 189 PLUS FR, installed beneath the resin build-up, which decouples the floor finish from the structural substrate and attenuates impact sound transmission between floors.
At 5-7mm total system thickness, it is the deepest build-up in the Arturo floor system range. Acoustic resin flooring is specified wherever building regulations, Part E compliance, or acoustic consultants require measurable impact sound insulation from a seamless finish floor typically multi-storey residential, student accommodation, hotels, and open-plan offices above habitable spaces.
The PU2060 body coat provides Shore D 60 hardness, delivering a harder, more resilient wearing surface than the comfort floor system, suited to medium-duty foot traffic and furniture movement without acoustic compromise.
Substrate & installation requirements
The acoustic system introduces additional installation stages compared to standard resin floor build-ups. The underlay bonding sequence is critical to acoustic performance, any deviation from the specified adhesive and installation method will affect dB rating.
-
Substrate must be dry, sound, and free from contamination that could impair adhesive bond
-
UZIN KR 430 adhesive applied to substrate before UZIN RR 189 PLUS FR underlay installation, don not substitute adhesive.
-
Underlay butt joints must be tightly abutted with no gaps. Gaps reduce acoustics performance and create void for the scratch coat to bridge.
-
Thixotropic agent must be added to PU2060 at correct ratio (0.5%–2.0% by weight) for scratch coat application, ensure consistent mix.
-
Two separate scratch coat applications required, each with 18 hour curing time between coats, do not compress the inter-coat curing window.
-
Ambient and substrate temperature between 10°C–25°C throughout all application and curing stages
-
Underfloor heating: commission 7 days prior to installation; switch off 48 hours before and during application

*Ensure the subfloor is dry, sound and free from materials that could impair adhesion.
**Apply the first scratch coat of Arturo PU2060 Self-smoothing Floor (consumption approx. 500 - 1,300 g/ m²) mixed with Arturo Thixotropic Agent as thickener. Add Arturo Thixotropic Agent until the desired thickness is achieved (consumption: 0.5% to max. 2.0% by weight). Curing time approx. 18 hours. After curing of the Arturo PU2060 Self-smoothing Floor, apply the second scratch coat of Arturo PU2060 Self-smoothing Floor (consumption approx. 500 - 1,300 g/ m²) mixed with Arturo Thixotropic Agent as thickener. Add Arturo Thixotropic Agent until the desired thickness is achieved (consumption: 0.5% to max. 2.0% by weight). Curing time approx. 18 hours.
***Apply Arturo PU3320 Coloured Satin Sealer before the seal coat.
