F Ball - Levelling compounds
F BALL’s Stopgap 800 Wearcoat is a self-levelling, commercial and industrial grade floor compound for upgrading and renovating new and existing internal floors in light to heavy duty applications and is designed to be left as a stand-alone wearing surface. These properties make it suitable for application in storerooms, workshops and warehouses, where floors will be heavily trafficked and subject to heavy loads. It is also proving popular in other settings for its naturalistic appearance, F Ball says.
When dry, Stopgap 800 displays varying colours and textures, and reportedly produces an attractive finish when polished. For these reasons, F Ball says it is considered to be a visually superior alternative to concrete by some. The manufacturer goes on to say these characteristics mean the product has become a popular choice amongst architects and interior designers for ambitious modern architectural projects.
F Ball’s Stopgap 800 was reportedly used to create a high-quality, contemporary flooring finish on the entire ground floor of a newly-constructed, lakeside residential property, with large glass windows, in Tattingstone, near Ipswich. The natural appearance of Stopgap 800 Wearcoat was said to be desired to create a harmonious transition between inside and outside environments.
Before any work was undertaken, contractors from the Polished Concrete Co., in Croydon, conducted a moisture test to ascertain levels of subfloor moisture in the building’s concrete subfloor, and it was determined that subfloor relative humidity (RH) levels were 75–80%. Therefore, F Ball’s Stopgap F77 two-part, epoxy resin waterproof surface membrane was installed over all ground floor areas to provide a barrier against excess moisture and prevent possible floor failure. The subfloor was then primed with a single coat of F Ball’s P131 primer to promote adhesion of the subsequently applied flooring compound.
Contractors could then proceed to install Stopgap 800 Wearcoat throughout the entire 200sq m ground floor of the building, including the entrance hallway, two bedrooms and living room. While still wet, an F Ball spiked roller was used, said to dispel any trapped air in the levelling compound and optimise the appearance of the finished result.
After the flooring compound had dried sufficiently, contractors polished the surface and applied a sealer to protect it from water and other liquids. In areas where water or other fluids may come into direct contact with the cured floor compound, F Ball recommends that the surface is sealed with Stopgap Seal water-dispersed modified polyurethane sealer. This provides what the company describes as a hygienic and protective surface and reportedly eases maintenance by reducing the adhesion of dirt and other debris. It also offers a level of chemical resistance to many commonly found chemicals in commercial applications.
Stopgap 800 can be applied over a wide range of absorbent and non-absorbent subfloor types, including sand/cement screed, concrete, granolithic, terrazzo, epoxy and polyurethane resins and Stopgap waterproof surface membranes, F Ball says. It can reportedly be applied in thicknesses between 5mm and 15mm. It is also said to be low odour, so it can be used while nearby areas remain in-use and open to the public. It can also be pump-applied up to 1000sq m per day.
