Whether you're a DIY enthusiast or a professional tradesperson, our products offer long-lasting protection without compromising value.

Why is wood preservation important

Bare wood is a natural material, making it prone to wear and damage if not properly treated with a wood preserver. Moisture, UV rays, fungi, and pests can degrade untreated wood, leading to cracking, rot, and structural issues. By applying the right wood preservative, you create a protective barrier that not only enhances the wood’s durability but also helps maintain its natural beauty.

Choosing the right wood preservative for your project

The success of your wood preservation project depends on selecting the right product for the type of wood, its exposure, and the level of protection needed. Different wood preservatives offer unique benefits, so understanding what works best for your project ensures long-lasting protection and aesthetic appeal.

• Type of wood

Softwoods, like pine or spruce, are more porous and require deep-penetrating preservatives to protect them from moisture and decay. Hardwoods, such as oak or teak, are naturally durable but benefit from surface-protective treatments that prevent cracking, drying, and UV damage.

• The function of the wood

For structural wood, such as beams and fences, heavy-duty preservatives are crucial to prevent wood rot and maintain structural integrity. Decorative wood, including furniture and exterior siding, can be protected with surface-sealing products that enhance durability while preserving its appearance.

• Oil-based vs. water-based

Oil-based wood preservatives penetrate deeply and offer superior moisture protection, making them ideal for outdoor surfaces under heavy exposure. Water-based options dry faster and are more environmentally friendly, making them suitable for quicker projects or low-maintenance applications.

• When to choose wood paint

If you want both protection and a decorative finish, wood paint is an excellent option. Full-covering wood paint provides a protective, weatherproof layer and allows you to customise the wood’s colour and appearance.

Tips for applying wood preservative

Proper application of wood preservatives is essential to protect your surfaces from moisture, rot, and general wear. By following the right preparation steps and applying the product correctly, you can extend the lifespan of your wood and keep it looking its best for years to come. Here are a few tips to help you achieve optimal results.

• Prepare the surface: Clean and sand the wood to remove dirt, debris, and old coatings. Dry the surface completely before applying wood treatment products.
•  
• Apply the preservative: Use a brush, roller, or spray system, depending on the size and scope of the project. Apply in even strokes, ensuring full coverage for maximum protection.
•  
• Allow time to dry: Follow the manufacturer’s instructions regarding drying times and additional coats, if needed.

After application, ensure you store any remaining product properly for future use.

The best option depends on the wood's exposure. For outdoor use, long-lasting, weather-resistant wood preservatives with UV and moisture protection are ideal. Indoor wood benefits from less intense, low-odour options that prevent drying or cracking.

Which is better, oil-based or water-based wood protection?

Oil-based wood protection penetrates deeply, offering long-term protection and resistance to moisture, making it ideal for outdoor use. Water-based options dry faster and work well for indoor applications or projects requiring quick reapplication.

What is wood protection?

Wood protection involves using a wood preservative to safeguard wood against damage from moisture, UV rays, mould, and insects. It enhances durability and longevity, preventing rot and surface wear while maintaining the wood’s appearance. 

What preparatory work must be done before painting?

You need to scrape off any loose paint. The surface must be clean and dry and have no flakes to ensure a good result that will last a long time.
