F BALL’s Stopgap 1600 fast-drying, fibre-reinforced smoothing compound is formulated specifically to encapsulate underfloor heating systems.
It can be applied between 3-40mm thick installed over internal subfloors in domestic and commercial environments and is reportedly walk-on hard from three hours after application and ready to receive floorcoverings in as little as 12 hours.
The product is suitable for use over a wide range of absorbent and non-absorbent subfloors, including sand/cement screed, tile backer boards, concrete, plywood, granolithic, terrazzo, epoxy and polyurethane resins, ceramic and quarry tiles, as well as Stopgap waterproof surface membranes. und
When working over retrofitted electrical wired or water-fed underfloor heating systems that are increasingly installed over subfloors as part of newbuild or refurbishment projects, it’s advisable to allow between 10-35mm of a smoothing compound above the pipes.
The amount depends on the type of system being installed and the manufacturer’s instructions (less is generally required for electrical wired systems).
F Ball says its entire range of smoothing compounds and adhesives are suitable for application over underfloor heating systems that are contained in a screeded subfloor.
It’s recommended systems are turned off 48 hours before the installation of floorcoverings, during and 48 hours after.
