StYccoBond F12 is a flammable rubber resin solution adhesive which withstands normal carpet cleaning techniques and is easily applied through an adjustable spray nozzle. STYCCOBOND F12 can be used for securing a wide range of materials but is particularly suitable for spot sticking carpet tiles (except PVC backed types) and for perimeter fixing of felt or rubber foam backed carpets. It is suitable for use on most common subfloors but not suitable on fully flexible vinyl floorcoverings. STYCCOBOND F12 can be applied to STOPGAP smoothing underlayments, structurally sound, smooth, dry subfloors of concrete and sand/cement screed, plywood, flooring grade chipboard and hardboard. STOPGAP Waterproof Surface Membranes, sound flooring grade asphalt and other non-absorbent surfaces must be skimmed with a minimum of 3mm of the appropriate STOPGAP smoothing underlayment.
