The secret to protecting exterior wood
Super hydrophobic
The ultimate defence against rainWater is the enemy of wood. Rain soaking into wood can lead to staining, organic growth, rot and decay.
Emperor Wood Waterproofer is uniquely engineered to create a super hydrophobic surface that causes rain to bead and roll away before it can soak in.
- Reduces water absorption by 96%
- Rain simply beads and rolls off the surface
- Helps prevent rot, decay and organic growth
- Keeps timber looking its best for longer
Highly breathable
Wood breathes naturallyKeeping rain out is only half the story. Moisture trapped within timber can also lead to damage over time.
Unlike many waterproofing treatments, Emperor allows moisture to escape naturally, helping keep timber dry from the inside out.
- Allows moisture to escape naturally
- Helps prevent moisture becoming trapped
- Keeps timber healthy for longer
- Reduces the risk of rot and decay
Invest once. Protect for years
The cheapest option often becomes the most expensive.
Reapplying wood treatments every few years wastes your time, money and effort, whilst allowing wood to gradually weather and deteriorate. Emperor Wood Waterproofer is designed to protect your wood for decades, helping keep it looking its best for longer with less maintenance.

Some products are invisible, whilst others leave a sheen, darken the wood or alter its appearance.

|
Most products offer some water resistance but do not achieve super hydrophobic performance.

|
Many products reduce breathability of wood, trapping moisture within the substrate.

Penetrates into the timber and chemically bonds within the substrate rather than forming a protective film on the surface.

Most conventional wood protectors work by forming a protective film on the surface of the wood, which can wear away or trap moisture.

Frequently Asked Questions
What does Emperor Exterior Wood Waterproofer achieve?
Wood, as a natural mineral surface, is highly porous, meaning it can absorb moisture. This moisture over time can lead it to discolour, rot and decay, leading to the need to regularly maintain the natural wood. By offering water repellent and highly breathable weather protection, Emperor Exterior Wood Waterproofer prevents this continual cycle of damage and helps to extend the lifespan of the wood.
By waterproofing wood, Emperor Exterior Wood Waterproofer also prevents the growth of unsightly lichens and moss, protecting the natural beauty of exterior wood long-term.
How has Emperor Exterior Wood Waterproofer been tested?
Emperor Wood Waterproofer has an independently tested by UKAS accredited laboratory Lucideon who tested the treatment in a 25 year accelerated weathering process. After 25 years of accelerated weathering, there were no signs of change in appearance or performance of the wood waterproofer. This certified that Emperor Wood Waterproofer has a 25 year proven performance, in accordance with EAD 040287-00-04:2018.
What surfaces can Emperor Exterior Wood Waterproofer be applied to?
Emperor Wood Waterproofer can be applied to any bare exterior wood. This includes wooden beams, log cabins, benches, decking, cladding and fencing. The treatment cannot be applied to previously painted wood as it is an impregnating system that must be able to absorb into the wood and chemically bond to the surface.
How do I apply the waterproofer?
You can apply Emperor Wood Waterproofer by paint roller, brush or pump sprayer. Apply to dry surfaces in temperatures above 5°C. Always avoid working in direct sunlight on hot days – it is much better to work in the shade. The treatment is a one-coat system, which once applied and fully cured will absorb into the wood to leave an invisible water repellent surface on the wood.
What if I get it on surfaces other than the wood?
Wash the affected area with hot soapy water and a cloth.
Is the product harmful to the environment?
The product is water-based and non-toxic.
Is the product safe and easy to use?
Whilst Emperor Wood Waterproofer is not a skin irritant, we would always recommend that care is taken when using it. Disposable gloves and goggles are advised, particularly if there is any breeze or wind to protect yourself from spray back. If you do get any wood waterproofer onto your skin, wash immediately with warm, soapy water.
What is the coverage?
The product is supplied ready for use. There is no need to add water or thin the product in any way. The product has a coverage of 5m2 per litre, meaning a 5 litre tub will cover up to 25 square metres depending on the surface being covered.
What is the difference between a wood waterproofer and a wood sealer?
While a sealer creates a water repellent, low breathability film on the surface of wood that can trap moisture inside the material, a wood waterproofer is an impregnating system which penetrates deep into the wood. This means that instead of creating a film on the surface, it provides the wood with water repellent properties from within the surface.
This not only means there is not film to breakdown due to weathering but also the breathability of the wood is not impacted. This is what gives Emperor Wood Waterproofer extreme 25 year durability, allowing it to be highly effective at waterproofing wood long-term.
