Stopgap 850 is a high-quality, non-structural exterior grade resurfacing compound designed for smoothing and levelling rough or mechanically damaged concrete or sand/cement screeds. Ideal for light to medium duty applications, Stopgap 850 provides an effective solution for restoring external surfaces. It can be left as a stand-alone exterior wearing surface, making it suitable for outdoor areas where durability and practicality are key.

Key Features:

• Exterior Application: Specifically formulated for outdoor use, Stopgap 850 is highly durable and capable of withstanding the elements, making it ideal for patios, pathways, and other exterior surfaces.
• Textured Finish: To achieve a more natural surface and reduce the risk of slipping when left uncovered, it is recommended to apply a scratch coat and brush finish for a textured profile.
• Pump Application: Stopgap 850 can be pump-applied for faster installation, with the ability to cover up to 900m² per day, depending on manpower, equipment, and application thickness.

Performance and Durability:

• Walk-On Time: Ready to walk on within 2 hours, allowing for quick turnaround and minimal disruption.
• Sealing: Surfaces can be sealed after 24 hours if required, further enhancing its weather resistance and durability.
• Thickness Range: Stopgap 850 can be applied between 5mm and 15mm in one layer, with the capability to fill up to 50mm in deeper areas, making it versatile for various surface conditions.
• Suitable for Falls: This compound can be laid to falls, making it ideal for sloped surfaces like ramps or drainage areas.

Versatility:

• Multiple Uses: Suitable for use beneath Stopgap waterproof surface membranes and Stopgap isolator membranes, offering flexibility in both its application and protection of external subfloors.
• Protein-Free: Stopgap 850 is protein-free, ensuring it is safe for use in sensitive environments and reducing the risk of biological contamination.
• Water-Mixed: The product is mixed with water, simplifying the application process and ensuring a strong, durable finish.

Coverage:

• 2.9m² at a thickness of 5mm

• 1.45m² at a thickness of 10mm

• 0.4m² at a thickness of 50mm

• 15m² at scratch coat thickness

Stopgap 850 is a reliable solution for exterior resurfacing, delivering a smooth, durable finish that can withstand the rigours of outdoor conditions. Its versatility, combined with fast-setting and easy application, makes it a practical choice for various external refurbishment projects.
