Ensure the paving is damp so the pointing doesn’t stick to the surface **Q: I bought this and used it on my path which has now set, but need more as it's not high enough and gaps. Can I put more ontop of set Sika??** A: I did this and it was fine, i just made sure it was well compressed, it has not separated so far after 2 years. It generally does seem to attract moss which nobody has mentioned. **Q: Can this be used to repoint already pointed Indian sand stone where grouting has come off ..?** A: You need to rake out all the existing pointing before repointing and push the Sika Fastfix into the open joints with a pointing trowel. **Q: how many bags will I need to do 120 slabs?** A: Everything depends on the width and depth of your joints,each box is supposed to do 20 sq metres but I found that I had to buy six bikes to do my 60 sq metres. Expensive but I think worth it for ease of use and hopefully durability. ## Frequently Bought Together - Sika – FastFix All Weather Self-Setting Paving Jointing Compound – Ready To Use – No Mixing Required – Dark Buff – 15kg – 21 sq. m - Amtech G1635 150mm (6") x 10mm (0.4") Tuck Pointer Trowel with Soft Grip - Faithfull FAIBRCOCO11 Soft Coco Hand Brush 275mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/130713945-sika-fastfix-self-setting-paving-jointing-compound-dark-buff-15kg](https://www.desertcart.pt/products/130713945-sika-fastfix-self-setting-paving-jointing-compound-dark-buff-15kg) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-08*
