SEALERS & CLEANERS FOR NATURAL STONE PAVERS IN AUSTRALIA

With over 38 years in the natural stone industry, I’ve had the privilege of working with and testing hundreds of sealers and cleaners. My journey has taken me through a wide range of products, from those priced at $150 per litre down to $15 per litre, and I’ve honed my criteria to focus on ease of use, cost, and, most importantly, effectiveness. After the closure of Tasman Chemicals, a trusted name in the past, my team and I sought a reliable replacement. That search led us to Rockstar Sealing, and after rigorous testing of their various sealers and cleaners, we’ve identified what we believe offers the best value for money while delivering on their promises.

The Challenge with Sealers

One common frustration in our trade is the marketing of sealers that claim “no colour change.” Having tested many, I can tell you that no sealer is truly invisible. Even the highest-quality options will impart a slight colour shift to natural stone pavers like Bluestone, Travertine, Limestone, Granite, or Sandstone. The key is finding a product that enhances rather than drastically alters the stone’s natural beauty. Rockstar Sealing’s range stands out here, offering solutions that align with this reality while providing robust protection.

Rockstar Sealing’s Standout Products

Rockstar Sealing, based in Melbourne, has developed a comprehensive lineup of sealers and cleaners tailored for Australia’s harsh climate. Here’s what I’ve found from their offerings at https://rockstarsealing.com.au/product-category/sealer/:

• Natural Finish Stone Sealer: This solvent-based penetrating sealer is a favourite for its high stain resistance against water and oil-based contaminants, while allowing vapour and salt transmission. It suits a variety of stones, including Limestone, Sandstone, Marble, and Concrete, reducing water intake by up to 97% on Sandstone. Applied as a final coat, it protects without significantly altering appearance, making it ideal for pavers where subtle enhancement is preferred.
• Green Star Sealer: A water-based option with low VOC content, this sealer is environmentally friendly and perfect for food environments or where solvent-based products aren’t suitable. It offers durable water and stain resistance without inhibiting water-vapour permeability, curing in 12 hours. Its rapid application and UV stability make it a practical choice for outdoor pavers.
• Bluestone Sealer: Specifically formulated for Bluestone and Basalt, this penetrating sealer provides high stain resistance without changing the stone’s look. It cures in 24 hours and is suitable for both domestic and commercial use, a testament to its versatility across Australian settings.
• Dense Stone Sealer: Designed for dense, hard-to-penetrate stones like Granite and Polished Concrete, this solvent-based sealer retards staining and eases cleaning. It’s a go-to for high-traffic areas where durability is critical.
• Stone Enhancer: For those wanting to deepen the colour of worn or faded pavers, this penetrating sealer enriches natural beauty while offering superior protection against contaminants. It’s breathable and suitable for indoor and outdoor use, with a full cure in 7 days.
• Anti-Graffiti Sealer: An easy-to-apply option that protects against graffiti without altering surface appearance, requiring reapplication every 3–5 years. It’s perfect for exposed pavers in urban areas.
• TuffSkin Surface Protection: A unique laminate solution that addresses etching and staining, offering a liquid-impermeable yet gas-permeable layer. It’s a game-changer for high-use pavers, resisting scratches with a long product life.

Cleaners to Complement

Pairing these sealers with the right cleaners is essential. Rockstar’s cleaners, available at https://rockstarsealing.com.au/product-category/cleaner/, include:

• Stone Clean Plus: A high-alkaline cleaner that removes built-up dirt and grime without residue, ideal for daily use on sealed pavers.
• Neutral Cleaner: A biodegradable, pH-neutral option safe for all surfaces, perfect for maintaining sealed natural stone and grout.

Why Rockstar Stands Out

What sets Rockstar apart is their commitment to performance under Australia’s challenging conditions—intense sun, rain, and salt exposure. Their products are backed by a 15-year warranty, and the ease of application (using lambswool applicators or low-pressure sprayers) suits both pros and DIYers. After testing, I’ve found their sealers deliver consistent protection without the dramatic darkening some competitors promise but fail to avoid. The slight colour change is manageable and often enhances the stone’s natural appeal.

My Recommendation

For Australian homeowners and tradespeople, I recommend exploring Rockstar Sealing’s range at https://rockstarsealing.com.au/product-category/sealer/ and https://rockstarsealing.com.au/product-category/cleaner/. Test on a small area first—every stone reacts differently—and choose based on your paver type and usage. With Rockstar, you get cost-effective, effective solutions that stand the test of time, a rare find after 38 years in the trade!
