Chimiver has the solution for you! Get your decking ready for summer!

But first, let’s take a step back…

What is Decking? Understanding Decking and Its Characteristics

Decking is a type of flooring primarily used in outdoor spaces such as gardens, terraces, balconies, and pool edges. It is typically made from wood, plastic, or composite materials, designed to withstand weather conditions and wear from foot traffic or garden furniture.

Wood decking consists of solid wood planks, generally sourced from durable wood species like oak, teak, western red cedar, or treated pine, making it perfect for outdoor environments and providing continuity with indoor parquet.

As a living, porous material, wood can be damaged by various factors over time:

• Exposure to weather elements: Rain, snow, sun, and humidity, to which wood is daily exposed, can cause wood to deteriorate (fading, graying, cracking, etc.).
• Moisture and mold: Wood in humid or shaded environments can develop mold.
• Wear and scratches: Regular use of decking and friction from foot traffic or garden furniture can cause scratches and superficial marks on the wood surface.
• Insufficient maintenance: Lack of regular maintenance, such as consistent cleaning and surface protection with appropriate oils, can accelerate decking deterioration.

Effective Tips for Maintaining Your Wood Decking

To keep wood decking in good condition over time, it is important to perform proper maintenance and take preventive measures: this can include regular cleaning, applying impregnating or protective oils, and replacing damaged or rotten boards.

It’s good to know some techniques and products to use to enhance the natural beauty of outdoor wood while preserving its value over time by focusing on:

• Restoring the original color;
• Nourishing;
• Protecting the wood;
• Cleaning and sanitizing.

Regenerating Solution for Restoring the Original Color of Grayed Wood Floors and Artifacts

LIOS Grigioff: is a water-based solution specifically designed to restore the original colour of exterior wood, making it ideal for wooden floors, decking, and outdoor wood structures that have turned grey due to exposure to sun, rain, and weathering.

The product works deeply without damaging delicate materials such as rubber seals and expansion joints. It is also a certified biodegradable and ecotoxic product, developed for effective yet sustainable wood restoration.

How to use LIOS Grigioff

The application is simple and fast. After thoroughly cleaning the surface to be treated, it is recommended to lightly wet the wooden floor with water. Then apply LIOS Grigioff directly onto the wood surface and let it act for approximately 10 minutes.

Once the product has worked, remove the greyed layer formed on the surface using:

• a stiff-bristle brush (click here for a DIY video);

After mechanical cleaning, rinse thoroughly with plenty of clean water.
