The Sika Sikaceram 621 Flowfix Jointing Compound in Light Grey is designed for homeowners and professionals seeking a durable, weather-resistant solution for paving joints up to 10mm wide. Its key benefit is the fast-setting, flowable formula that ensures strong adhesion and a professional finish, even for large outdoor areas subject to heavy use. A potential consideration is the need for careful mixing to achieve the correct consistency.

No, the compound cures to a non-permeable finish and does not require additional sealing.
It is suitable for porcelain, ceramic, and natural stone paving. Always test in an inconspicuous area if unsure about specific stone compatibility.
Ensure you have added the correct ratio of water during mixing. Adjust with small amounts of water or compound as needed, mixing thoroughly.
The compound may not have been sufficiently flowable, or the joints may have been too deep for the consistency. Ensure thorough mixing and consider a second application if necessary after initial set.
Remove excess compound as soon as possible after application, ideally before it begins to set. If it has started to harden, use a stiff brush and be careful not to dislodge the jointing compound.
This may indicate insufficient mixing or the wrong water ratio. Ensure consistent mixing and correct proportions for future applications.
Setup:
Compatibility:
This product is suitable for use with porcelain, ceramic, and natural stone paving.
Care:
Clean application tools immediately after use with water. Once cured, the jointing compound is low maintenance, but avoid aggressive cleaning methods that could damage the surface.
