STOPGAP 1200 is a high performance smoothing compound, designed for fast and efficient preparation of sound internal subfloors before the installation of new floorcoverings. This low odour, two-component compound sets and dries quickly, making it ideal for time-sensitive projects. It has a rapid walk-on-hard time from just 60 minutes and allows floorcoverings to be laid from 4 hours, allowing projects to be completed with minimal downtime.
It effectively works over old adhesive residues, including bitumen and carpet tile tackifiers, without the need for priming. You can use this high performance smoothing compound for patch filling timber floors prior to overlaying with plywood. It is also suitable for use in clinical and biologically sensitive areas such as hospitals, laboratories, and clean rooms.
STOPGAP 1200’s moisture-resistant properties make it suitable for application over damp, clean and uneven concrete and cement screeds prior to the application of STOPGAP Waterproof Surface Membranes or STOPGAP Isolator Membrane.
When mixed with our STOPGAP 1200 Liquid, STOPGAP 1200 meets the standards of the IMO which makes it suitable for use in marine flooring applications.
STOPGAP 1200 provides reliable, high-quality results every time. See how flooring contractors used STOPGAP 1200 in one of our high-scale case studies here.
