How To Apply | Sika FastFix All-Weather Jointing Compound
This video demonstrates the application and capabilities of Sika FastFix All-Weather Jointing Compound, a self-setting material designed for paving joints. The footage details its active resin technology, formulated to create a hard-wearing finish that resists shrinking or cracking. A primary benefit displayed is the option to apply the compound in both dry and wet conditions, allowing for use on patios and pathways throughout different seasons.
The process starts with showing the surface preparation, wetting the paving thoroughly before application. The instructions specify that gaps should be at least 20mm deep and 5mm wide. The demonstration shows how to open the packaging and distribute the compound in small, manageable amounts. Using a soft broom, the operator sweeps the material into the joints, then compacts it with a pointing trowel or iron. The video includes a “top up and compact again” step to fill the voids completely. Keeping the surface wet during this stage helps stop staining and assists with filling the gaps correctly.
Beyond basic application, the visual demonstration covers some of the specific product attributes. It illustrates how the hardened joints act as a barrier against weed growth. The video also addresses waste reduction, clearly showing how to store leftover product in a bucket of water to keep it soft for up to a month. This function helps save material for future repairs. The footage also outlines setting times based on the weather. It explains that the product sets within 6-12 hours in dry weather but takes longer in wet conditions.
The demonstration confirms compatibility with various paving types, offering a clear visual reference for maintaining stone or concrete surfaces.
