RAINCOAT and RAINCOAT FLOOR: Oil for Outdoor Decking and Wood Protection

Outdoor wood is one of the most fascinating materials, but also one of the most exposed. Without proper protection, sun, rain, and humidity can quickly compromise its appearance, causing greying and loss of strength.

For this reason, choosing an effective and long-lasting exterior wood oil is essential.

With RAINCOAT (oil for vertical outdoor wooden structures) and RAINCOAT FLOOR (oil for outdoor decking and floors), Chimiver offers a professional water-based solution designed to protect and enhance all outdoor wooden surfaces, from window frames to decking.

Protection for Outdoor Wood: Why Choose RAINCOAT and RAINCOAT FLOOR

Chimiver’s water-based impregnating oils penetrate deeply into the wood, reinforcing lignin and slowing down natural degradation. This results in:

• Water-repellent protection: the wood resists rain and humidity while maintaining its natural appearance.
• Durability and stability: the wood remains stronger over time, reducing greying.
• Sustainability: products compliant with LEED®, BREEAM®, WELL, and CAM building protocols, ideal for environmentally conscious projects.

RAINCOAT or RAINCOAT FLOOR: Which Exterior Wood Oil Should You Choose?

The main difference between the two products lies in the type of surface to be treated:

• RAINCOAT (oil for vertical outdoor wooden structures) is the ideal choice for vertical elements such as window frames, gazebos, fences, or canopies. In these applications, it provides protection while enhancing the natural look of the wood.

• RAINCOAT FLOOR (professional oil for decking and outdoor flooring) is specifically developed for walkable surfaces. It is therefore perfect for outdoor wooden floors, poolside areas, terraces, and walkways, where higher resistance to wear is required.

How to Apply Outdoor Wood Oil: Step-by-Step Guide

To achieve the best results in terms of protection and durability, it is important to follow the correct application procedure:

Step 1: Wood Preparation

Sand with 120-grit paper and remove dust and residues. A clean, smooth surface allows the product to penetrate deeply, ensuring uniform protection against sun, rain, and humidity.

Step 2: Application of the First Coat

Shake RAINCOAT or RAINCOAT FLOOR well before use and apply along the wood grain using a brush, cloth, or applicator, avoiding excess build-up. This first coat creates the protective base.

Step 3: Second Coat Application and Protection

Allow to dry for 2–4 hours without sanding, then apply the second coat using the same technique, spreading the product evenly to avoid overlaps and color differences. This double-coat system ensures a complete protective barrier, ideal for outdoor flooring, decking, and vertical structures.

Step 4: Ideal Conditions

Apply between 10°C and 25°C, preferably in the morning. If the wood is exposed to direct sunlight, slightly dampen it before application. Avoid temperatures above 30°C to prevent compromising product performance. (Always refer to the technical data sheet before use.)

To make the application of RAINCOAT and RAINCOAT FLOOR even easier, Chimiver provides detailed video tutorials on its YouTube channel. These visual guides show step by step how to prepare the wood, apply the product correctly, and achieve a uniform, long-lasting finish while avoiding common mistakes. Following the videos allows you to apply our impregnating oils with confidence, maximizing both protection and aesthetic results for outdoor wood.

Maintenance of Decking and Outdoor Surfaces

One of the main advantages of RAINCOAT and RAINCOAT FLOOR is their ease of maintenance. Treated surfaces do not require sanding and can be maintained over time with regular cleaning.

For routine care, the use of specific cleaners such as LIOS Sundeck Soap is recommended. This cleaner is ideal for washing outdoor wood and removing dirt, chlorine residues, and salt deposits. Regular maintenance helps preserve both the effectiveness of the treatment and the appearance of the wood.

For cleaning outdoor wood and maintaining vertical surfaces and items such as tables, chairs, and garden furniture, Chimiver offers LIOS Legno Pulito, a ready-to-use nourishing cleaner specifically designed for the care of outdoor wood. Thanks to the presence of plant-based essences naturally unpleasant to insects and its pleasant fragrance of citrus, citronella, and eucalyptus, it ensures complete and effective maintenance. Ideal for both decking and outdoor wooden furniture, regular use helps keep surfaces protected and enhanced.
