Emperor Masonry Paint has gained a strong reputation among professional decorators for its innovative features and impressive performance. This review, compiled from multiple conversations with decorators, highlights their experiences, opinions, and recommendations for this premium exterior paint. Known for its hydrophobic properties, breathability, and heat retention, Emperor Paint claims to be the best choice for long-lasting masonry protection. But is it worth the high price tag? Let’s explore the pros, cons, and real-world feedback from decorators who have used it.

Key Features of Emperor Paint:
- Hydrophobic and Breathable: Emperor Paint repels water, keeping the masonry dry while allowing moisture to escape from the inside, preventing damp issues.
- Self-Cleaning: The paint’s super hydrophobic surface helps to resist dirt and grime, making it ideal for areas prone to weather exposure.
- UV Resistant: It maintains its colour and durability even when exposed to direct sunlight for extended periods.
- Energy Efficiency: Emperor claims the paint helps with heat retention, adding an insulating effect to the home, which decorators have confirmed in some instances.
- Longevity: It offers up to 20 years of protection, far surpassing standard masonry paints like Sandtex and Dulux Weathershield.
Positive Feedback:
- Easy Application: Many decorators, such as Preston H and Mark R, were impressed by how easy the paint was to apply when following the recommended system. As Preston noted, “It was an absolute pleasure, easy to apply, follow the system correctly for 100% guaranteed benefits.”
- Long-Term Durability: Several users highlighted Emperor’s longevity as a major selling point. Jim R stated, “You won’t have to paint again for twenty years,” emphasising the paint’s durability. The promise of long-lasting protection is a key reason decorators are willing to recommend it, despite the high price.
- Superior Protection: Emperor’s hydrophobic and breathable properties are highly praised. James Y said, “It’s silicone-based, super hydrophobic, and highly breathable, which makes it perfect for old buildings.” This makes it ideal for structures that require moisture management, such as cottages or homes with render issues.
- Customer Satisfaction: Decorators like Bruc Decor mentioned that customers often opt for Emperor when offered the choice. While the product is expensive (around £118.75 per 10 litres), customers appreciate the benefits it offers, especially for homes near the coast or in areas exposed to harsh weather conditions.
Criticisms and Challenges:
- Price: At £100-£125 for 10 litres, Emperor Paint is not cheap. As Bruc Decor mentioned, “It’s great… just expensive at £125 for 10L.” While most decorators acknowledge the benefits, the cost remains a significant hurdle for many, especially for larger projects.
- Thickness and Workability: Several decorators, including Adam M, struggled with the paint’s thickness, finding it difficult to apply under certain conditions. Adam shared that the paint “dries and goes claggy on your brush in less than a minute.” Some decorators suggested thinning the paint slightly (despite the manufacturer’s recommendations), especially in warmer weather, to improve workability.
- Requires a Primer: Emperor Paint requires the use of its primer on bare surfaces. Jordan Y asked whether he could apply the paint directly, but was advised by Daniel G that a primer was necessary for unpainted masonry. This adds an additional step and cost to the process, making the overall job more expensive.
- Mixed Reviews on Performance: While the majority of decorators praised the paint, there were a few who found it difficult to work with. Adam M expressed frustration after recommending Emperor to two customers and delivering “the worst finish” he had ever produced. It’s important to follow manufacturer instructions closely, and using the right tools (like stiff oil brushes) seems to be essential for getting the best results.
Product Comparisons:
- Sandtex & Dulux Weathershield: While cheaper alternatives like Sandtex and Dulux Weathershield are mentioned frequently, Emperor is often seen as superior in terms of longevity and protection. Decorators like Paul B acknowledged that standard paints might be sufficient for less demanding jobs, but Emperor is the better option for customers who prioritise durability.
- Weathershield vs Emperor: Some decorators, such as Jim R, pointed out that while Dulux Weathershield is good for certain projects, it can’t match Emperor’s longevity or hydrophobic features. Jim summarised, “Emperor… then you won’t have to paint again for 20 years.”
- Comparison to Kiem and ProPERLA: Emperor is often compared to high-end competitors like Kiem and ProPERLA. Some decorators, including Graeme W, noted that Kiem is slightly better, but it also comes at a similarly high price.
Recommendations:
- For Coastal Properties: Decorators who work on coastal properties often recommended Emperor for its superior resistance to weather and moisture. Lewis M, who frequently works by the sea, mentioned that Emperor is “the best stuff going” for homes exposed to salty air and heavy rain.
- For Old and Rendered Buildings: Emperor Paint’s breathability and hydrophobic properties make it ideal for older buildings or those with render. Several decorators recommended it for customers dealing with damp problems or poorly weathered surfaces.
- Use Proper Tools: When working with Emperor, decorators recommend using tools like a stiff oil brush to make application smoother. Jordan E emphasised the importance of technique, suggesting that improper application can lead to poor results.
Final Verdict:
Emperor Masonry Paint is clearly a premium product that delivers on its promises of durability, weather protection, and ease of use. However, it comes with a significant price tag and requires careful application to achieve the best results. While not every decorator has had a flawless experience, the majority who use it agree that its benefits outweigh the downsides, especially for high-end or long-term projects. If you’re willing to invest in quality and long-lasting performance, Emperor Paint is worth considering.
