Where can WET ECO be used?

WET ECO can be used in various settings to protect and enhance, but it is particularly suitable for outdoor use. You can use it for a range of materials including those mentioned above, plus slate patios and outdoor barbecue areas.

By using this colour-enhancing protector, you can confidently extend its benefits to areas where protection against stains, dirt, and foot is of utmost importance. Additionally, WET ECO not only helps surfaces maintain their aesthetic appearance but it also simplifies the cleaning and maintenance process, which is particularly crucial for exterior materials.

How to use WET ECO

Before application, ensure that the surface is clean, dry, and free from any debris or previous coatings.

Step 1 – Preparation

  • Gather the necessary materials, including FILA’s WET ECO, a clean microfiber cloth or fleece applicator, and protective gloves
  • Shake the WET ECO container gently to ensure proper mixing of the product

Step 2 – Application

  • Put on protective gloves to safeguard your hands during the application process
  • Pour WET ECO into a bucket and dip a microfiber cloth or fleece applicator into the product
  • Start by applying the product evenly onto the surface, working in small sections at a time
  • Use smooth, overlapping motions to ensure consistent coverage
  • Pay attention to gaps and grout lines, ensuring they are adequately coated

Step 3 – Drying and finishing touches

  • Allow the treated surface to dry for 2-3 hours. During this time, WET ECO will fill up the microscopic pores in the surface to allow the protective properties to penetrate the material effectively
  • During this time, keep the surface protected from foot traffic, water, and other potential sources of contact or moisture
  • Once the surface has fully dried and cured, inspect the results
  • You can then apply an additional coat, following the same steps as above 2-3 hours after the initial application
  • Once complete, wait 12 hours before walking on the surface


Remember to always refer to the specific instructions provided by FILA for precise application details and recommended drying/curing times. By following these step-by-step instructions, you can ensure that FILA’s WET ECO is applied effectively, providing the desired protection and enhancement to your natural stone and terracotta surfaces.

Preventive measures

Upon applying this sealer, we always recommend maintaining the surface with a neutral detergent like CLEANER PRO.

For surfaces with low absorbencies, such as slate, Botticino, or Carrara marble, it is advised to dilute WET ECO with water and never use it for polished surfaces either. It’s also crucial to check the weather forecast for when you expect to leave the product to cure. Applying the product before rain can compromise its effectiveness and may require reapplication.

Analysis and testing methods

In order to evaluate the performance and efficiency of WET ECO, several tests have been conducted over the years. One of these tests is the UNI EN ISO 10545-12, which assesses the product’s ability to maintain the frost resistance of terracotta.

Other tests conducted focus on the effectiveness of the product’s protection. To evaluate its performance, various staining tests were carried out using the STANDARD EN16301- Stains Resistance Test method for Natural Stone. These tests involved applying different types of regulated staining agents to the surfaces, allowing them to work for 4, 8, or 24 hours before removal.

After the tests, the surfaces were examined to determine if any stains were present. The remaining stains were then evaluated based on their intensity and assigned numerical values. The results demonstrated that WET ECO provides excellent surface protection, as the material exhibited no signs of alteration or damage even after the staining agents were applied.


Accreditations for WET ECO

Impressively, WET ECO carries both GEV certification and the EC1Plus mark, demonstrating its adherence to stringent environmental standards and its support in earning LEED credits.

Additionally, it has obtained the Indoor Air Comfort Gold certification due to being a VOC-free product, which underlines the product’s commitment to maintaining excellent indoor air quality and providing a healthier environment.
