Stopgap 850 COSHH Assessment Form

A three-page COSHH Assessment Form for Stopgap 850

Stopgap 850 is a specialised exterior-grade smoothing compound designed to effectively level and refine rough or damaged concrete surfaces and sand/cement screeds. This versatile product is ideal for various outdoor applications, including balconies, patios, garages, and walkways. It can also serve as a standalone wearing surface, providing functionality and aesthetic appeal.

Once cured, Stopgap 850 exhibits excellent water and frost resistance, making it suitable for varied weather conditions. Its robust formulation ensures that it can withstand exposure to rain and frost, maintaining its integrity and performance over time.

This smoothing compound is engineered to create a beautifully smooth and level surface on diverse outdoor subfloors, particularly targeting rough, uneven, or otherwise compromised ones. Its compatibility with other F. Ball products, such as waterproof membranes, enhances its utility, making it a reliable substrate for additional floor coverings.

Stopgap 850 can be applied in thicknesses ranging from 5mm to 15mm, offering flexibility for different project requirements. It can be efficiently pumped for larger areas, streamlining the application process and minimising labour time.

To further optimise performance and reduce slippage, a scratch coat followed by a brush finish is recommended. This creates a more natural-textured surface, enhancing grip and improving the overall aesthetic of the finished product. In summary, Stopgap 850 is a premium solution for outdoor flooring that combines durability, versatility, and ease of use.
