Built to last: Why 100% silicone sealants is a smart choice

At Blackwoods, we’re passionate about progress—and that means partnering with suppliers who deliver quality, reliability, and purpose. That’s why we’re proud to support Geared Up Culcha (GUC Industrial®), an Indigenous-owned business powering momentum in the industrial space with their range of 100% silicone sealants.

No shortcuts. Just results.

When it comes to sealants, experience tells us one thing: cutting corners costs more in the long run. Whether you're sealing bathrooms, windows, or expansion joints, 100% silicone is the trusted choice for tradies who want to get it right the first time.

Unlike extended or “contractor grade” silicones—often bulked out with mineral oils or fillers—GUC Industrial®’s 100% silicone range is made from pure silicone polymers. That means better performance, longer life, and fewer callbacks.

Why extended silicones fall short

• Shrinkage & Peeling: Fillers evaporate, causing cracks and failures—sometimes within months.
• Yellowing: Discolouration ruins the finish and undermines your reputation.
• Poor Flexibility: Less silicone means less movement tolerance—critical in dynamic joints.
• Adhesion Issues: More filler = less grip. That’s a risk you don’t need.
• More Callbacks: Every failure costs time, money, and trust.

Why GUC Industrial® 100% silicone delivers

• Built for Harsh Conditions: UV, rain, heat—no problem. These sealants are made for Australia.
• Superior Flexibility: Moves with the structure, not against it.
• Long-Term Finish: No chalking, no yellowing—just a clean, professional look.
• Certified Safe: Meets Australian Standards, including potable water and low-VOC compliance.
• Trusted by Pros: Because your work should look as good in five years as it does on day one.
