Industrial Flooring - F Ball & Co
F BALL & CO’s Stopgap 800 Wearcoat and Stopgap 850 Exterior are said to offer the capability to create smooth and level wearcoat surfaces for indoor and outdoor industrial applications.
Typically, an industrial floor will be subject to heavy loads, such as forklift trucks or trolleys carrying heavy equipment. To ensure a finished floor can withstand this daily exposure, while maintaining its integrity and aesthetic appearance, it’s essential the subfloor is properly prepared.
For internal industrial applications where floorcoverings aren’t required, such as factories or warehouses, rapid-setting, self-levelling wearing surface compounds, such as Stopgap 800 Wearcoat, offer what’s claimed to be an ideal solution.
‘Suitable for application in thicknesses of 5-15mm, special class abrasion resistance makes it suitable for these heavy-duty industrial applications,’ says the company. ‘To cover large floor areas quickly, Stopgap 800 can also be pump-applied.’
Prior to the application of the wearcoat, as with any flooring project, a thorough assessment of the subfloor should be made to ensure it’s clean, sound and free from damp and contaminants, such as oil or grease. If the relative humidity of the subfloor is below 75%, the installation may proceed, but if the level is above this, a waterproof surface membrane (WSM) should be been applied.
‘Stopgap 800 is suitable for use over a wide range of subfloor types, including sand/cement screed, concrete, granolithic, terrazzo, epoxy and polyurethane resins, as well as Stopgap WSMs,’ says the company. ‘Subfloors should be primed before applying the levelling compound.’
In areas where water or other fluids may come into direct contact with the cured levelling compound, F Ball recommends the surface is treated with a sealer, such as Stopgap Seal; a water-dispersed modified polyurethane sealer. ‘This provides a hygienic and protective surface and 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 industrial/commercial applications,’ says the company.
For external applications or for situations, which may nominally be inside but still subject to external weather conditions, a purpose-designed exterior grade levelling compound is required. ‘Stopgap 850 Exterior can be used in light- to medium-duty areas and once applied and cured is unaffected by rain or frost,’ says the company.
‘It’s typically used to smooth and level rough and mechanically-damaged concrete or sand/cement screeds. If required it can be finished with a suitable non-slip coating or an appropriate exterior floor covering, or it can be left as a standalone exterior wear surface.’
As with Stopgap 800 Wearcoat, Stopgap 850 Exterior can be applied at thicknesses of between 5mm and 15mm and can be pump-applied to cover large areas quickly. Stopgap 850 can, additionally, be used as a ‘filled mix’ with Stopgap graded aggregate for application up to 50mm thick.
Owing to its moisture tolerant properties, Stopgap 850 can reportedly be used internally over damp, uneven concrete and sand/cement screeds prior to the application of a waterproof surface membrane.
