Product Information

Full details

Protek Multi-Purpose Exterior Wood Preserver is an ideal solution for homeowners and DIY enthusiasts looking to safeguard their outdoor timber projects from decay, rot, and insect damage. Its deep-penetrating, water-based formula acts as a crucial barrier against fungal growth and wood-boring insects, doubling as an effective primer for subsequent paints or stains; however, users should note that it requires a weather-resistant top coat to ensure long-term UV protection and durability.

FAQs

Can I use this product indoors?

This product is specifically designed for outdoor timber and is intended to provide protection against environmental hazards like rot and insects common in exterior settings.

Do I need to sand the wood before applying?

Yes, ensure the timber is clean and free of dirt or loose fibers. Sanding helps open the wood pores, allowing for better penetration of the preservative.

Is this preserver colored?

No, this specific product is clear, meaning it will not change the color of the wood.

How many coats should I apply?

For optimal protection, apply 2-3 coats, ensuring each coat is allowed to dry thoroughly before the next.

Can I leave the wood treated with just this product?

While it provides biological protection, it is not designed to withstand UV rays and weathering on its own. A top coat is required for lasting protection.

What tools are recommended for application?

A synthetic brush is recommended for the best application experience and finish.

Troubleshooting

The product is taking too long to dry.

Ensure the application area has adequate ventilation and humidity levels are low. Avoid applying in direct, intense heat or near freezing temperatures.

Uneven finish after applying top coat.

Ensure that the wood surface was completely saturated and dry before the top coat was applied. Lightly sand the surface if the preserver raised the grain.

Pros and Cons

Pros

  • Protects against both fungal rot and insect infestation
  • Water-based formula ensures easier cleanup
  • Functions as a high-quality primer for final finishes
  • Quick-drying properties for faster project turnover
  • Deep-reaching formula for internal wood health

Cons

  • Requires a separate top coat for weatherproofing
  • Not intended for use as a standalone final finish
  • Requires 2-3 coats for maximum effectiveness
  • Limited to outdoor timber applications

Setup, Compatibility & Care

Before application, ensure all wood surfaces are clean, dry, and free from loose debris or previous surface coatings that might prevent penetration. Apply the product using a quality synthetic brush, working carefully along the wood grain to ensure even coverage. The product covers approximately 6-8 square metres per litre. After the final coat of preserver has fully dried, follow up with a weather-resistant top coat. Regularly inspect your treated timber once a year to check for any signs of weathering, and re-apply top coats as needed to maintain the integrity of the underlying preservative layer.
