Quick Recommendation Guide

- Installing windows or glazing → Hypersil 911 glazing silicone.
- Sealing around natural stone (marble, granite, travertine) → Stonesil — specifically formulated not to stain stone.
- Gaps in timber cladding or skirting that need painting → Hypercryl 363 — paintable acrylic latex.

Common Questions
Should I use Hypersil 912 or PascoFlex PU25? — Use Hypersil 912 for internal wet areas (bathrooms, kitchens, laundries). Use PascoFlex PU25 for external joints, expansion joints, or anywhere you need to paint over the sealant. Silicone cannot be painted; polyurethane can.
What is the difference between Hypersil 912 and 912 MATT? — Same mould-resistant formula, different finish. Standard 912 has a gloss finish; 912 MATT has a contemporary satin finish that pairs well with matt tapware and modern tile trends.
Can I use Hypersil 912 on natural stone? — No. Standard silicone can stain porous stone. Use Stonesil instead — it is specifically formulated for marble, granite, travertine, and engineered stone.
What Aquaproof membrane should I use? — Aquaproof 201FR (fibre-reinforced) is a popular choice for standard bathroom waterproofing. For heavy-duty or external applications, consider Aquaproof 110 polyurethane membrane. Visit the TradieCart website for the full Aquaproof range or contact Pasco for technical advice.
Do you sell fire-rated sealants? — Yes. Firejoint PU (polyurethane) and Firecryl (acrylic) are both available for fire-rated joint applications in commercial buildings.
What backing rod size do I need? — The backing rod should be slightly larger than the joint width to compress in and sit at the correct depth. Common sizes: 6mm, 10mm, 13mm, 15mm, and 20mm in closed-cell; 20mm and 22mm in open-cell.
