1. Ensure the paving is installed as per watchpoints leaflet and that all joints to be pointed with Sika FastFix® All Weather are free from standing water, dirt, debris or weeds. The dimensions of the joints must allow for a full compaction of the material once applied. The minimum joint depth should be at least 20 mm and the joint width 5 mm.
2. Wet thoroughly the entire area where Sika FastFix® All Weather is going to be applied with water. This includes not only the joints, but also the entire slabs. Allow any standing water to drain before Sika FastFix® All Weather is applied.
3. Remove the product from the packaging and cut the foil pack. Once punctured or opened, the material must be used within one hour. Any unused material can be stored in the bucket, immersed in water, for up to 1 month.
4. Use Sika FastFix® All Weather in small manageable amounts. Avoid spreading over a large area before application. Ensure material is all loose by raking through. Do not try to break up and use any small set lumps. Do not add any extra sand.
5. Using a soft broom, or hand brush for smaller areas, work Sika FastFix® All Weather into the joints. Make sure each joint is completely filled. If the freshly laid product is flooded, for instance due to rain, the setting period might be extended.
6. Using a suitable pointing trowel make sure the freshly applied Sika FastFix® All Weather is thoroughly compacted within the joints. The process should also smoothen/flatten the surface to the desired level. The step of thorough compaction is essential.
7. Sika FastFix® All Weather will start to set in 6-12 hours above 15 °C in dry conditions. Allow up to 5 days for full set in temperatures between 4 °C and 15 °C. Contact with rain or moisture can temporarily soften the product if wetted before full set.
