Pros and Cons of Sandstone Sealers

Sandstone is a popular natural stone material used in various outdoor applications, such as patios, driveways, walkways, and garden paths. While sandstone is naturally durable and resistant to wear and tear, it is still vulnerable to damage from weathering, staining, and water penetration. Many homeowners and contractors use sandstone sealers to enhance their longevity and appearance. This article will discuss the pros and cons of using sandstone sealers, focusing on the popular PicsealSandstoneSealer in the UK market.

What Is a Sandstone Sealer?

A sandstone sealer is a type of penetrating sealer applied to the surface of sandstone to protect it from moisture, stains, and other forms of damage. The sealer penetrates the stone’s pores, creating a barrier that repels water and other liquids, preventing them from soaking into the stone and causing damage. Sandstone sealers are available in different types, including solvent-based and water-based sealers.

Pros of Sandstone Sealer

There are numerous advantages of a sandstone sealer. Some of the benefits include the following:

1. Protects the stone from water damage: Water is one of the main culprits of damage to sandstone, as it can penetrate the surface and cause cracking, spalling, and staining. A sandstone sealer creates a protective layer on the stone’s surface, preventing water from seeping in and causing damage.
2. Enhances the natural beauty of the stone: A good sandstone sealer can enhance the natural colour and texture of the stone, making it look more vibrant and appealing. The sealer can also bring out the natural veining and patterns of the stone, giving it a unique and attractive appearance.
3. Prevents staining: Sandstone is prone to staining from spills, dirt, and other substances. A sealer creates a barrier on the stone’s surface, preventing stains from penetrating the stone and causing permanent discolouration.
4. Makes the stone easier to clean: Sealed sandstone is easier to clean and maintain, as dirt, dust, and other debris are less likely to stick to the surface. Regular cleaning with mild detergent and water is needed to keep the stone looking clean and fresh. 

Cons of Sandstone Sealer

Although this sealer has numerous pros, it also has some drawbacks. Some of the cons include the following:

5. Can alter the appearance of the stone: Some sandstone sealers can alter the natural appearance of the stone, making it look darker or glossier than before. Choosing a sealer compatible with the stone is important and does not alter its natural colour and texture.
6. Can be difficult to apply: Applying a sandstone sealer requires some skill and experience, as it needs to be applied evenly and thoroughly to ensure maximum protection. Some sealers may also require multiple coats, which can be time-consuming and labour-intensive.
7. Can be expensive: Good quality sandstone sealers can be expensive, especially if you have a large area to cover. However, the cost of the sealer can be offset by the savings in maintenance and repair costs over the long term.
8. Needs to be reapplied periodically: Sandstone sealers are not permanent and must be reapplied periodically to maintain effectiveness. The frequency of reapplication depends on the type of sealer, the amount of foot traffic, and exposure to the elements the stone receives.
9. Prevents mould and mildew growth: Sandstone exposed to damp environments can be vulnerable to mould and mildew, which can cause health problems and damage the stone. A sandstone sealer creates a barrier that inhibits the growth of mould and mildew, helping to keep the stone healthy and clean.
10. Increases the stone’s lifespan: Sandstone is a natural material that can last for decades or centuries with proper care and maintenance. A sandstone sealer can help increase the stone’s lifespan by protecting it from damage and deterioration, reducing the need for costly repairs or replacement.
