MACt Seal Final Concrete Sealer
$203.50 – $3,272.50 Inc GST
Description
MACt Seal Final Coat is a specialised, two-component urethane-acrylic hybrid designed as the ultimate protective topcoat for GFRC (Glass Fibre Reinforced Concrete) projects. By bonding a silicon-repellent layer to previously sealed surfaces, this final coat adds robust water resistance, exceptional scratch protection, and non-yellowing clarity. Whether applied to concrete basins, baths, or benchtops, MACt Seal Final Coat offers a user-friendly, low-foaming formulation that maintains a natural, colourless finish—and you can customise the sheen level from a subtle matte to a brilliant high gloss.
Key Features & Benefits
- Advanced Water Repellence
- Silicon Repellent: Bonds seamlessly to sealed surfaces, delivering enhanced moisture and contaminant resistance.
- Ultimate GFRC Protection: Perfect for high-exposure applications like basins, baths, and countertops.
- Flexible Finish Options
- Multiple Heavy Coats: Build a rich, high-gloss finish—though extended cure times are required for complete cross-linking.
- Fewer, Thinner Coats: Achieve a faster-curing, matte sheen with minimal impact on drying time.
- Easy Mixing & Application
- 16:1 Base-to-Activator Ratio: Consistent, straightforward dosing ensures optimal performance.
- Two-Hour Work Window: Plenty of time to apply the final coat before the mixture sets.
- Foam Roller-Friendly: Non-foaming formulation minimises roller lines and overlap marks.
- High Scratch & Contaminant Resistance
- Superior Durability: Guards against abrasions and stains, preserving the pristine look of polished GFRC surfaces.
- UV-Stable & Non-Yellowing: Maintains clarity and colour fidelity over the product’s lifetime.
- Single, Lasting Top Layer
- Final-Layer Only: Must be applied after base sealing coats; attempting to coat over Final Coat will lead to surface rejection.
- Long-Term Hardness: Achieves final cure in 7 days, delivering outstanding longevity and resilience.
Recommended Usage & Application
- Mixing
- Base : Activator = 16:1 by Volume: Carefully weigh or measure the correct activator amount, add to the base, and stir thoroughly for ~3 minutes.
- Work Time: Approximately 2 hours post-activation; only mix the amount needed for one complete topcoat.
- Application
- Apply After Base Sealer: Ensure the underlying sealer coats are cured and free of any surface defects.
- Foam Roller Method: The special low-foaming formula applies smoothly with minimal fuss. Back rolling is optional.
- Multiple Heavy Coats or Fewer Thin Coats: Heavier coats need longer cross-link times (producing higher gloss), while thinner coats cure faster with a matte result.
- Curing Guidelines
- Initial Cross-Link: 24 hours for the first reaction; avoid heavy traffic or moisture exposure during this period.
- Final Hardness: Complete at around 7 days—ideal for maximum scratch and stain resistance.
- Important Note
- Final Layer Only: MACt Seal Final Coat cannot be resealed over; any future sealing attempt requires mechanical removal down to the concrete substrate.
