Sika FastFix All Weather Jointing Compound - Grey

No, Sika FastFix is specifically formulated for joints that are a minimum of 5mm wide and 20mm deep to ensure proper setting and performance. Using it on smaller joints may lead to poor results.

Initial set time is typically 6-12 hours above 15°C in dry conditions. However, full setting and maximum strength can take up to 5 days, especially in cooler temperatures between 4°C and 15°C.

No, Sika FastFix is a ready-to-use compound and requires no mixing. Simply open the tub and apply directly to your paving joints.

Sika FastFix is described for 'outdoor patios, pavements and paths' and is designed for exterior conditions. It is not recommended for indoor applications.

It is suitable for a wide range of outdoor paving, including footpaths, stone setts, cobbles, and Indian sandstone slabs.

To keep any unused compound viable for future projects, store it in its original tub, ensuring it is completely submerged in water, and seal the lid tightly.

It is best to avoid heavy foot traffic or placing weight on the newly jointed area until it has had sufficient time to set, ideally after the initial 6-12 hour period, and preferably until full cure in cooler conditions to ensure optimal strength.

Ensure the joint depth and width meet the minimum requirements (5mm wide, 20mm deep). Verify the ambient temperature during and after application; full setting can take up to 5 days in cooler temperatures (4°C-15°C). Avoid disturbing the compound during the curing phase.

Check if the joints were filled to the required 20mm depth. Inadequate depth may not provide a sufficient barrier. Also, ensure the paving sub-base itself is properly prepared to deter weed growth from underneath.

Excess compound should be brushed off immediately after application. If it has dried, gently try to scrape it off with a plastic scraper or a stiff brush. Avoid using harsh chemicals or metal tools that could damage the paving.

This typically occurs if the unused compound was not completely submerged in water during storage. For future storage, ensure all remaining compound is fully covered by water to maintain its workability.
