Which Sealer Should You Use? A Surface by Surface Product Guide

Choosing the right sealer depends on the surface you want to protect. Sandstone, block paving, imprinted concrete, concrete, and tarmac all require different types of sealers to prevent water damage, staining, and weather wear. This guide explains which sealer works best for each outdoor surface and why using the correct one is essential for long lasting protection.

Outdoor surfaces are constantly exposed to rain, sunlight, frost, and everyday wear. Without proper sealing, these surfaces can lose their appearance, become damaged, and require costly repairs over time.

What Is a Sealer and Why Is It Important?

A sealer is a protective coating applied to surfaces to reduce water absorption, prevent stains, and protect against weather damage. Sealers also make surfaces easier to clean and maintain.

For outdoor areas, sealers help protect against rain, UV exposure, moss growth, oil spills, and surface erosion. Sealing can also enhance the natural colour and finish of materials such as stone, concrete, and paving.

Without sealing, outdoor surfaces are more likely to crack, fade, stain, and deteriorate over time.

Which Sealer Is Best for Sandstone Surfaces?

Best sealer for sandstone:
An Extreme Seal Block Paving Sealer is best for outdoor sandstone surfaces as it protects against moisture while allowing the stone to release trapped water.

What Is Sandstone?

Sandstone is a natural stone commonly used for patios, pathways, and garden features. It is valued for its warm tones and natural texture. However, sandstone is porous and can absorb water easily.

Why Sealing Sandstone Is Important

Sealing sandstone helps prevent water penetration, staining, algae growth, and surface damage caused by frost. A good sandstone sealer preserves the natural look of the stone while extending its lifespan.

Which Sealer Works Best for Block Paving?

Best sealer for block paving:
A dedicated block paving sealer is ideal for protecting block paving driveways and patios from weeds, staining, and weather damage.

What Is Block Paving?

Block paving is widely used for driveways, patios, and paths. It is durable and attractive but can suffer from weed growth, joint sand loss, and oil stains.

Why Sealing Block Paving Is Important

Sealing block paving helps lock in jointing sand, reduce weed growth, protect against oil and dirt stains, and minimise fading caused by sunlight.

What Is the Best Sealer for Imprinted Concrete?

Best sealer for imprinted concrete:
An imprinted concrete sealer designed to enhance colour and protect the surface is the best option.

What Is Imprinted Concrete?

Imprinted concrete, also known as decorative concrete, is commonly used for driveways and patios. It is designed to mimic stone or brick patterns.

Why Sealing Imprinted Concrete Is Important

Sealing imprinted concrete helps maintain colour, prevent surface wear, and protect against oil stains, dirt, and weather exposure. Without sealing, the surface can fade and lose its visual appeal.

Can Concrete Sealers Be Used Outdoors?

Best sealer for concrete:
A high quality concrete sealer is suitable for both outdoor and indoor concrete surfaces.

What Is Concrete?

Concrete is a strong and versatile material used for driveways, patios, paths, garages, and industrial floors. Despite its durability, concrete is porous and can absorb moisture and stains.

Why Sealing Concrete Is Important

Sealing concrete improves resistance to water, oil, and general wear. It also helps reduce cracking and surface deterioration caused by weather exposure.

Is Tarmac Sealer Suitable for Driveways?

Best sealer for tarmac:
A tarmac sealer is specifically designed to protect tarmac driveways and parking areas.

What Is Tarmac?

Tarmac is made from crushed stone and bitumen and is commonly used for driveways and access roads. Over time, it can fade, crack, and become stained by oil and fuel.

Why Sealing Tarmac Is Important

Sealing tarmac helps restore colour, protect against weather damage, and extend the life of the surface. It also helps prevent water penetration and surface breakdown.

Frequently Asked Questions

How often should outdoor sealers be reapplied?

Most outdoor sealers last between one and three years. High traffic areas such as driveways may require more frequent reapplication depending on weather exposure and usage.

Can one sealer be used for all surfaces?

No. Each surface requires a specific type of sealer. Using the wrong sealer can result in poor protection and an uneven finish.

How should a surface be prepared before sealing?

Surfaces should be clean, dry, and free from dirt, moss, oil, and debris. Proper preparation ensures better adhesion and longer lasting results.

Conclusion

Choosing the right sealer for your outdoor surfaces is essential for long term protection and appearance. Sandstone, block paving, imprinted concrete, concrete, and tarmac all require specific sealers designed for their unique properties. By selecting the correct sealer and maintaining it properly, you can protect your surfaces from damage, enhance their appearance, and extend their lifespan.
