Self-levelling wearing surface for internal commercial and industrial floors.
STOPGAP 800 is a self-levelling commercial and industrial grade floor compound used for upgrading and renovating new and existing internal floors in light to heavy duty applications where floorcoverings are not required to be installed. It is suitable for use in areas such as storerooms, post rooms, workshops, corridors, warehouse setc. STOPGAP 800 is grey in colour.
STOPGAP 800 is dimensionally stable and is supplied as a pre-blended dry powder, which is designed for application between 5-15mm. It is protein-free which allows it to be used in biologically sensitive areas.
STOPGAP 800 is for application over a wide range of subfloor types including and / cement screed, concrete, granolithic, terrazzo, epoxy and polyurethane resins and STOPGAP waterproof surface membranes.
In areas where water or other fluids may come into direct contact with the cured material, the surface must be sealed with STOPGAP SEAL. This also helps to protect the floor surface and ease maintenance by reducing the adhesion of dirt and other debris.
STOPGAP 800 can also be pump applied.
Absorbent surfaces – Prime with a minimum 2 coats of dilute STOPGAP P131 to prevent un controlled rapid drying of the compound which may lead to surface pin holing, poor flow characteristics, surface imperfections and colour variation. Very absorbent surfaces may need additional coats of primer. If applying over STOPGAP 600, this should be done within 24 hours and the surface should first be primed with a dilute coat of primer followed by a neat coat.
Non-absorbent surfaces - such as terrazzo, quarry tiles and STOPGAP waterproof surface membranes should be primed with neat STOPGAP P141.
Apply the primer using a soft brush and do not extend the stated coverage. Site and substrate conditions vary, the chosen priming system should be evaluated over a trial area to ensure an optimum surface finish.
Alternatively, STOPGAP F77 may be used as a priming system in conjunction with a kiln dried grit0.7-1.2mm:
Damp subfloors: Install STOPGAP F77 waterproof surface membrane as directed and within24 hours apply a second coat of STOPGAP F77. Whilst still wet, fully blind the surface with the grit and allow to cure before vacuuming away all loose grit and installing STOPGAP 800.
Dry, absorbent subfloors: Apply one coat of STOPGAP F77 and whilst still wet, fully blind the surface with the grit and allow to cure before vacuuming away all loose grit and installing STOPGAP 800.
