FASTFIX REALLY IS THAT EASY Sika is your best ally! Review: Great product - Great product. Application was very easy, i just wet the area let the access was dry up a bit and put the product on. Used a large soft brush when first applying and a smaller soft brush and pointer to fill all the gaps between the blocks with no mess a solid finish. Dried very quickly but the weather was very warm. One thing I would recommend is do small areas at a time this may be a bit more time consuming but it is well worth it as the mix doesn’t dry out as quick. Overall I would recommend this product if used correctly it looks great when finished. Review: Works well, doesn't require any skill - I needed to re-grout / re-point my patio. Rather than get in a professional, I gave it a go myself with this stuff, and am very happy with the results. The slabs that were wobbling are now secure, it's filled in the gaps that were opening up in the original fixing, which went in seven or eight years ago, and it doesn't seem to have caused any damage to the surfaces of the Indian Sandstone slabs. One note of caution is that, once the sealed bag is open, you have an hour before this begins to set. Fortunately, this 14kg tub contains two bags, so it's not a question of doing it all in one go – but it is important to have the area cleared and cleaned, and any existing loose grout dug out before starting. It then suggests you wet the slabs thoroughly before beginning, to prevent any staining. I did this – and the slabs don't appear to have discoloured. My approach was to pour the powder around two or three slabs at a time, brush that in, and then move on. Once I'd finished the first bag, I ran a pointing trowel over everything to pack it down – though with hindsight, I think a finger may have done a better job. Once finished, the advice is that it may take up to five days to set. I used a stiff broom on it every day for those five days, and got up quite a lot of the residual. That stuff that's left – mostly where the slabs have ridges and hollows – is tough to get off after the five days are up but with a pressure-washer and a broom it gets blasted free after a bit of effort. Now I've got the patio cleaned-up, I'm noticing a few areas I might go over again. I've got about a quarter of a bag left. The advice is that this will stay useful for a month after opening, if you pour it into the tub and then cover it with water. On the whole, I'm very happy with this – and cautiously optimistic it's a job that you can do yourself quite cheaply in comparison to hiring a professional. ## Features - Contains cobalt bis(2-ethylhexanoate) .

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by M***1 on 28 July 2026* Great product.

Longer to set hard than expected. Looks great. *by P***L on 27 April 2024* I am middle-aged lady who gardens when needed - mainly mowing the lawn. After pressure cleaning the patio -not cleaned since laid 5 years ago- all the grouting between the paving slabs was blown out. I ordered this product after reading the feedback. It arrived a few days later. The container is not large but it is quite heavy (for a little person to move about). I spent a few hours on Sunday sweeping and then hosing down the patio then carefully filling and packing in this jointing compound in the gaps between the paving stone. The mixture was a dryer and then I expected. I did not think there was a strong smell to it. I was a bit concerned it would not pull together and set, or be enough to cover the patio (21 sq mtr. 40cm x 40cm slabs). On hindsight I could have just poured the mixture along the gaps like the Sika instruction videos on Youtube but I worked in small sections of patio and spooned in the mixture before packing it well into gap with a plastic scraper. I think because of this, I managed to grout the whole patio with one tub but I could have saved a lot of time if I had poured, swept and packed the mixture. I was just not confident I could work fast enough on a big area. You do need to make sure the patio is wetted well before working with the mixture. I kept hosing the sections down as I went along. I was worried excess water would affect the setting of the mixture but it does not. I kept the unused mixture airtight/moist and only took out what I needed on each section. I ended up with mixture to spare. After finishing the job, I could not resist checking every couple of hrs to see if the mixture was hardening up. It got to the point I was convinced I had got a bad tub as the mixture was loose and soft in the gaps for a few days. A day of heavy rain on the Mon probably did not help. I was relieved the mixture did not get washed away. There was a very fine film - like petrol - that came off the mixture in the rain but it did not seem to leave any noticeable residue on the paving slabs. In total it has probably taken a week for the mixture to go hard (weather was average UK spring temperature 10-15 degrees a few days of rain) and now it seems fine and I am pleased with the outcome. If you have not used this stuff before, my advice would be to follow the videos and have patience. It is not cheap but it is easy to use, very little mess and the results look good. Follow the instructions especially the gap size minimum and wet the patio before hand. I think I will get many years without having to worry about scraping weeds off the patio joints. ## Frequently Bought Together - Sika – FastFix All Weather Self-Setting Paving Jointing Compound – Ready To Use – No Mixing Required – Flint – 15kg – 18 sq. m - Proops Double Ended Brick Jointer/Finger Trowel/Pointing Tool/Mortar Finishing Tool (S7853) Free UK Postage (1) - Faithfull FAIBRCOCO11 Soft Coco Hand Brush 275mm --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/205118454-sika-fastfix-self-setting-paving-jointing-compound-flint-15kg-18](https://www.desertcart.com.kw/products/205118454-sika-fastfix-self-setting-paving-jointing-compound-flint-15kg-18) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-08-13*
