High Performance Smoothing Compounds
Stopgap 300
Heavy-Duty Floor Smoothing Compound
STOPGAP 300 is a fast drying, self-levelling, heavy duty smoothing compound, suitable for use in light to heavy duty areas. This smoothing compound is used for preparing sound absorbent and non-absorbent subfloors prior to the installation of new floorcoverings. With its high compressive strength, STOPGAP 300 offers a durable, stable base for floorlayers to work on.
It is dimensionally stable with heavy-duty properties, ensuring long lasting performance even in demanding environments. It comes as a pre-blended dry powder designed for application between 2 – 20mm, and enables users to easily apply it by hand or with a pump.
This smoothing compound allows users to lay floorcoverings on absorbent surfaces from 6 hours, and provides a walk-on-hard time of just 90 minutes at 20°C. This fast turnaround time helps flooring contractors to complete jobs more efficiently and to a high-quality standard. Its low odour, protein-free formula makes it suitable for use in biologically sensitive areas such as hospitals.
STOPGAP 300 delivers consistent results with its excellent fast drying and self levelling properties, making it a trusted choice by flooring professionals especially for heavy duty purposes.
