The impact resistance of the surface finish is a fundamental parameter in evaluating wood flooring, particularly in environments where the surface must combine elegance, aesthetic continuity, and reliability in daily use.
Within Berti Lab, the Impact Test represents an essential technical assessment for analyzing the behavior of the varnished surface under localized stress and examining the finish’s ability to protect the wood over time.
Through this verification, Berti studies the relationship between surface protection, varnish film integrity, and durability, transforming technical analysis into a concrete product development tool.
What Is the Impact Test
The Impact Test is an assessment used to evaluate the impact resistance of the varnish applied to the wood flooring surface.
The test is performed by dropping a mass of defined weight from various heights onto a precise point on the varnished surface, thereby simulating conditions comparable to actual use and concentrated stress that may occur in everyday environments.
The goal is to simulate real-world conditions such as:
- falling objects
- accidental impacts
- concentrated stress
At the end of the test, the following are analyzed:
- impact resistance of the finish
- varnish film integrity
- any cracking or peeling
- surface deformation of the substrate
The Impact Test is therefore an important assessment for objectively understanding how effectively the finish can absorb and distribute impact energy, preserving the aesthetic and functional quality of the surface.
The Berti method
In Berti Lab, the Impact Test is part of a research and quality control process that accompanies the development of wood surfaces and finishing systems applied internally.
The objective is not simply to verify theoretical resistance, but to understand how the surface responds to localized stress, thereby guiding work on varnish adhesion, protective film continuity, and surface stability over time.
The Extremestrong technology is based on a multi-layer coating system with UV curing, designed to improve the resistance of the surface film.
The finishing cycle, consisting of 7 layers of high-resistance water-based coating, contributes to:
- increasing the impact resistance of the varnish film
- improving adhesion to the substrate
- reducing the risk of surface damage
- maintaining the continuity of protection
This approach enables Berti to transform technical verification into product culture: a method founded on observation, testing, interpretation of results, and continuous improvement.
Observed results
The Impact Test provides useful insights into surface behavior under localized stress and allows for deeper examination of the relationship between finish, protection, and the perceived quality of the wood flooring.
Tests conducted show that Berti coated surfaces exhibit:
- good impact resistance of the varnish film
- no peeling or breaking of the finish (under the tested conditions)
- limited evidence of surface marks
- maintenance of the protective function
The results indicate that the varnish is capable of absorbing and distributing impact energy without compromising the protection of the wood.
Rather than as a simple technical verification, the Impact Test result is interpreted by Berti as part of a product knowledge process, useful for supporting quality designed to maintain reliability and continuity over time.
Why it is important
Accidental impacts, falling objects, and concentrated loads represent frequent situations in the daily life of a wood surface. Even when they do not compromise the structure of the flooring, they can significantly affect surface protection and the perceived quality of the finish.
The impact resistance of the varnish is crucial for:
- preserving the appearance of the surface
- maintaining the protection of the underlying wood
- reducing maintenance interventions
A high-performance varnish film helps ensure the overall durability of the floor over time.
Through the Impact Test, Berti objectively verifies the resistance of its surface finish, confirming the effectiveness of the coating cycles developed in-house.
For Berti, the value of this assessment concerns not only the ability to withstand an impact, but the opportunity to observe the actual contribution of the finish to preserving the protection and appearance of the wood flooring over time.
The Finish as Surface Protection
In the behavior of a wood surface, the finish plays a central role also with respect to accidental impacts. Its function is not only to enhance the flooring aesthetically, but also to help protect the material and preserve its continuity under concentrated stress.
The Impact Test is particularly useful precisely for this reason: it allows concrete observation of how the finishing system responds to everyday use conditions and evaluation of its ability to keep the flooring protected, stable, and visually consistent.
In the case of Berti surfaces, this analysis is part of a broader vision oriented toward enhancing:
- impact resistance
- protective film continuity
- varnish adhesion to the substrate
- aesthetic stability of the surface over time
Fields of application
Impact resistance is a particularly relevant aspect in all contexts where wood flooring must combine aesthetic value and continuity of daily use.
For this reason, the Impact Test assumes particular importance in environments such as:
- residential spaces used daily
- high-traffic environments
- contract settings
- hospitality spaces
- projects where the surface must maintain protection and aesthetic quality over time
This assessment helps to better understand the suitability of the surface in relation to usage expectations and the need to preserve its appearance and reliability.
Research, verification, development
Through the Impact Test, Berti confirms an approach to quality founded on research, development, and performance control.
Each assessment contributes to building deeper knowledge of the surface and its behavior, transforming technical analysis into a useful tool for product development.
In this perspective, impact resistance is not only a technical performance, but an integral part of a vision in which wood flooring is interpreted as a synthesis of material, protection, and design.
