STOPGAP 1100 GYPSUM can be pump applied up to 1500m2 per day, dependent upon manpower, thickness applied and equipment used.

Product Information

Stopgap 1100 Gypsum, a product by F Ball, is a self-levelling underlayment designed specifically for use over calcium sulphate based screeds, notably anhydrite. It is ideal for usage before installing new floor coverings. This product is exceptionally stable and comes in a pre-blended dry powder form. It is applicable between 2 - 10mm thickness scales. An outstanding feature of this underlayment is its protein-free composition, making it suitable for use in biologically sensitive environments like hospitals.

The calcium sulphate base of Stopgap 1100 makes it exceptionally viable for smoothing and levelling screeds of a similar construct. Despite this specificity, it also boasts versatility and can be used across a wide variety of other subfloor types. This includes Stopgap waterproof surface membranes, sand-cement screeds, concrete, sound asphalt, granolithic, terrazzo, epoxy and polyurethane resins, and also ceramic and quarry tiles. This attribute makes it highly adaptable for a range of flooring needs.

Stopgap 1100 Gypsum also showcases convenience and efficiency in its application process. It can be pump applied which significantly speeds up the application process and can cover up to 1500m2 per day. The rate of application can vary depending on the manpower, thickness of application, and equipment being utilised. This capacity for rapid application underscores the underlayment as an optimal choice for large-scale flooring projects which require a swift turnover.

Coverage is another significant aspect of this product. A single 22kg bag of Stopgap 1100, when mixed with 5.5 litres of clean water, is able to cover approximately 50m2 to a thickness of 2-3mm. This high yield ratio makes Stopgap 1100 Gypsum not just a practical choice but also a cost-effective one for those seeking a reliable and efficient smoothing underlayment for their flooring projects. Therefore, Stopgap 1100 should be a go-to choice for individuals and contractors seeking a high-quality, versatile underlayment for large-scale flooring applications.

Great selection of products. They were the lowest price on the Internet for the vinyl flooring I wanted. Quick delivery and when the tub of glue was delivered damaged, they called me to tell me of the damage and sent out a replacement the next day.
