Guide to choosing the best water-based varnish for exterior wood

Outdoor wood requires special care to withstand weather conditions and maintain its beauty and functionality. At Irurena Group, we understand the importance of protecting and beautifying your furniture, terraces, and wooden structures. Therefore, today we offer you a comprehensive guide on how to choose the best water-based varnish for exterior wood.


Why is it important to varnish outdoor wood?

Varnishing outdoor wood not only enhances its appearance but also protects it against factors such as moisture, UV rays, temperature changes, and insects. A good varnish creates a protective barrier that prevents wear and extends the lifespan of your furniture and structures.

Benefits of water-based varnishes

1. Eco-friendly and Low Odor

Water-based varnishes are a more environmentally friendly option due to their lower content of volatile organic compounds (VOCs). Additionally, their low odor makes them more comfortable to apply and use.

2. Quick Drying

One of the main advantages of water-based varnishes is their quick drying time. This allows for multiple coats to be applied in less time, speeding up the process of protecting and beautifying the wood.

3. Easy Cleaning

Tools used to apply water-based varnishes can be easily cleaned with water and soap, making maintenance easier and reducing the need for specific cleaning products.

4. Durability and Resistance

Despite being water-based, these varnishes provide long-lasting protection against moisture and UV rays, keeping the wood in excellent condition for longer.

How to Apply Water-Based Varnish for Exterior Wood

Step 1: Surface Preparation

Before applying the varnish, ensure the surface is clean, dry, and dust-free. Gently sand the wood to open the pores and allow better adhesion of the varnish.

Step 2: Applying the Varnish

Apply a thin, even coat of varnish using a quality brush. Allow it to dry completely before applying a second coat. Most water-based varnishes require at least two coats for optimal protection.

Step 3: Regular Maintenance

To keep the wood in perfect condition, check and reapply the varnish every two years or when you notice signs of wear.

Factors to Consider When Choosing a Water-Based Varnish for Exterior Wood

1. Weather Conditions

Choose a water-based varnish suitable for your area’s climate. In areas with high humidity, ensure the varnish has water-resistant properties and UV protection for sunny climates.

2. Type of Wood

Some woods require a specific type of varnish. For example, hardwoods like oak may need a more robust varnish than softwoods like pine.

Our exterior products are designed for use on any type of wood, but if you encounter an unknown type of wood, consult our technical specialists.

3. Use and Wear
