Best Brick Sealer Overall

 Stormdry Masonry Waterproofing Cream
  • 25-Year Protection: Offers long-lasting protection with a single coat application, reducing the need for frequent reapplication.
  • Easy Application: The cream-based formula can be applied with a brush or roller, making it user-friendly for both professionals and DIYers.
  • Breathable: Allows masonry to expel moisture from within, preventing trapped water that can cause long-term damage.
  • Colourless Finish: Dries invisibly, preserving the natural look of brick, stone, and other masonry surfaces.
  • Wide Surface Compatibility: Works effectively on brick, stone, mortar, sandstone, and granite, providing versatile protection for various surfaces.

  • Higher Upfront Cost: As a premium product, Stormdry may be more expensive than other brick sealers, though the long-term durability offsets the need for frequent reapplication.
  • Requires Clean Surfaces: For best results, the surface must be thoroughly cleaned before application, which can add to preparation time.

If you’re looking for the best brick sealer on the market, the Stormdry Masonry Waterproofing Cream takes the top spot on our list. Its powerful waterproofing properties, combined with ease of use and durability, make it an outstanding choice for both professionals and DIYers alike.

Stormdry is specially designed to protect a wide range of surfaces, including brick, stone, mortar, sandstone, and granite. By creating a strong, invisible barrier, it keeps external walls dry, which, in turn, helps maintain warmth and protects internal cavity wall insulation from rain and moisture damage. This is a huge advantage for anyone concerned about energy efficiency and avoiding damp issues.

One of the standout features of this product is its long-lasting protection. Stormdry offers up to 25 years of water repellency, which means you can apply it once and not worry about reapplication for decades. The cream-based formula penetrates deep into the masonry, creating a robust water-repellent barrier with just one coat.

Unlike some waterproofing solutions that trap moisture inside, Stormdry is breathable, allowing the masonry to expel any moisture from within. This helps prevent damage like spalling and cracking, which can result from trapped moisture in non-breathable sealers. Additionally, it maintains the thermal properties of your wall’s insulation, keeping your home warmer and reducing energy costs.

Once cured, Stormdry is completely colourless, meaning it won’t alter the natural appearance of your brick or stonework. This is ideal for those who want to preserve the aesthetic of their property while benefiting from premium protection. Application is straightforward, whether you’re using a brush or roller, making it accessible even for those new to DIY projects.

For added peace of mind, Stormdry has been independently tested and verified. It’s BBA-approved (certificate number: 15/5198) and has been rigorously tested by the University of Portsmouth, proving its performance in the toughest conditions.

The Stormdry Masonry Waterproofing Cream is hands down the best brick sealer available today. With its premium waterproofing abilities, easy application, and long-lasting protection, it’s a smart investment for anyone looking to protect their property from moisture damage. Whether you’re a DIY enthusiast or a professional, this sealer’s impressive 25-year protection and breathability make it a standout product in the market. If you’re serious about preserving your masonry, Stormdry is the way to go.

  • Highly Water Repellent: Provides excellent water resistance, protecting brick, concrete, stone, and other masonry surfaces from moisture damage.
  • Breathable: Allows moisture vapour to escape while still repelling water, preventing issues like trapped moisture and dampness.
  • Transparent Finish: Dries to a clear, matt finish that won’t alter the natural look of the material.

  • Not Suitable for All Surfaces: Cannot be applied to rubber, plastic, or timber, limiting its versatility.
  • Shorter Longevity: While effective, its lifespan may not match that of premium, long-lasting sealers like those offering 20+ years of protection.

If you’re in search of a budget-friendly yet highly effective water sealant, Everbuild 402 Water Seal is a great option. Its solvent-free, easy-to-apply formula offers dependable water-repelling properties without the hefty price tag. Here’s a closer look at what makes this product stand out.

Everbuild 402 creates a robust waterproof coating that can protect a variety of surfaces including brick, concrete, render, stone, and pebble dashing. Once applied, it forms a water-resistant barrier while still allowing the surface to breathe and moisture vapour to evaporate. This breathable nature ensures that trapped moisture doesn’t cause damage, making it a great choice for protecting masonry.

This water seal provides durable, long-lasting protection due to its deep penetration into the material. The result is a matt finish that’s transparent once dried, so it won’t alter the appearance of your brickwork or stone, making it ideal for those looking to preserve the original look of their surfaces.

One of the most appealing aspects of Everbuild 402 is its water-based formula. It’s non-flammable and solvent-free, making it a safer option for both the environment and those applying it. Cleanup is easy with just water, and the lack of solvents ensures that you won’t have to worry about strong chemical odors during application.

Everbuild 402 is extremely user-friendly and can be applied using a brush, roller, or even a low-pressure garden sprayer, making it versatile enough for DIYers or professionals. The milky-white liquid dries to a clear finish and can even be applied to damp surfaces—perfect for those who may not have the luxury of waiting for the wall to fully dry.

This product is available in two sizes: a 5-litre or 25-litre jerry can, offering flexibility for both small and large projects. Whether you’re sealing a small patio or a larger external wall, Everbuild 402 has a size that fits your needs.

The Everbuild 402 Water Seal is an excellent option for anyone looking for a cost-effective, easy-to-apply water sealant that still delivers high performance. With its water-based, solvent-free formula, it’s safe and straightforward to use. Plus, it offers the added bonus of being able to apply it to damp surfaces, saving you valuable time. While it may not be suitable for every material (it doesn’t work on plastic, rubber, or timber), it performs exceptionally well on brick, stone, and concrete surfaces. If you’re in need of reliable protection against water damage without breaking the bank, Everbuild 402 is a solid choice.

Clive's Smart Buying Tips

  1. Consider the Type of Sealer: There are two main types of brick sealers—penetrating and film-forming. Penetrating sealers provide long-lasting protection by sinking into the brick, while film-forming sealers create a protective layer on top. Choose based on your needs for durability and appearance.
  2. Check for UV Resistance: Ensure the brick sealer is UV resistant, especially for outdoor use. UV-resistant sealers protect the bricks from sun damage, preventing fading, cracking, or discoloration over time.
  3. Look for Water Repellency: A high-quality brick sealer should offer excellent water repellency to prevent moisture absorption, which can lead to mold, mildew, and freeze-thaw damage.
  4. Breathability is Key: The sealer should allow moisture from within the brick to escape while still protecting against external water. Non-breathable sealers can trap moisture and lead to brick deterioration.
  5. Durability and Longevity: Choose a brick sealer that is known for its long-lasting performance. Some sealers last only a couple of years, while higher-end ones can last up to 10 years, reducing the need for frequent reapplications.
