One-part moisture curing adhesive for heavy-duty interior/ exterior use.
STYCCOBOND F74 is a single pack, moisture curing polyurethane adhesive suitable for fixing floorcoverings and for seaming synthetic grass carpets. It is water resistant and although it is suitable for outdoor use, it is not intended to be used as, or a substitute for a surface damp proof membrane. It is resistant to oil and grease and is suitable for use over normal underfloor heating systems.
STYCCOBOND F74 can be used for securing needle punched / fibre bonded carpets, synthetic grass carpets, PVC, latex, polyurethane and rubber backed carpets, vinyl and rubber floorings.
Refer to the F. Ball Recommended Adhesives Guide for details of specific Floorcoverings
STYCCOBOND F74 can be applied to STOPGAP smoothing underlayments, sound, smooth subfloors of concrete, granolithic, sand/cement screeds and plywood.
When laying impervious floorcoverings onto non-absorbent subfloors e.g. vinyl flooring onto terrazzo, the subfloor must be prepared and skimmed with a minimum3mm of the appropriate STOPGAP smoothing underlayment to assist curing.
For details on other subfloors, contact our Technical Service Department
Proper subfloor preparation is essential for the correct installation of any floorcovering. Subfloors must be sound, smooth, dry (<75% RH) and free from laitance and any contaminants which will affect adhesion. Use STYCCOCLEAN C140 for removing grease, oil, polish, soap etc. from non-absorbent substrates.
Concrete and sand/cement screeds must be fully cured and any laitance or surface treatments must be removed. The subfloor and ambient temperatures must be above10°C. Underfloor heating must be off for at least 48 hours before and after application.
For application in external environments, although it is not necessary for subfloors to be totally dry, the surface must be visibly dry before the adhesive is applied.
