Best Sealer for Natural Sandstone Patios and Walls
Natural sandstone is a timeless choice for patios and walls. To truly protect that beauty, you need to seal it. Whether you face foot traffic, rain, or sun exposure, using the best sealer for sandstone keeps your space looking fresh and lasting for years.
In this blog, we’ll explore why sealing is essential, which products to use, and why Protectguard range is the top choice for both professionals and DIY.
Why You Need to Seal Natural Sandstone
Sandstone may look tough, but it’s very porous. That means it absorbs water, oil, and dirt quickly. Over time, this can lead to discoloration, algae growth, and even surface erosion.
Applying a sandstone wall sealer or penetrating stone sealer is crucial. It adds an invisible layer of protection that keeps the stone’s natural texture while repelling the elements.
Key Benefits of Sealing Sandstone
- Prevents water damage and surface erosion
- Blocks oil and food stains on patios
- Helps fight algae and mold growth
- Improves the stone’s natural color
- Protects against UV damage and fading
Different Types of Sealers (And Which One Is Right for You)
- Penetrating Sealers
These soak into the stone and provide deep protection without changing its appearance. They’re ideal for vertical surfaces like sandstone walls.
- Oil Based Sealer
This type enhances color and provides extra durability, making it great for driveways or patios that see a lot of use.
- Pigmented Sealer
Perfect for when you want a decorative finish along with protection. It adds subtle tints while sealing the surface.
- Waterproof Sealer
This is essential in wet or humid climates. It keeps water out, preventing cracking and moss buildup and works well for facade protection, but for floors, stain protection is also needed.
