Sika – FastFix All Weather Self-Setting Paving Jointing Compound – Ready To Use – No Mixing Required – Stone – 15kg – 19 sq. m

This stuff is excellent, so easy to use and looks great!!

This review is in two bits. The product and the supplier/delivery.I've used this product a number of times and it's considerably easier to use than cement based mortar joints albeit considerably more expensive. The main benefits are that you can use it in the wet - on fact it needs to be be wet to work, it cleans up well without sticking too much to the paving slabs and the speed of use is fast thus saving valuable time.I find that it takes two or three uses of a pointing tool to get it packed down hard enough to make a solid job. If you don't do this then jet washing can blow it out or at least partially blow it out.Setting time is temperature dependent. I don't use it below 10C because it takes a few days to go off. However above that then it's hard within a couple of days.Where I do get problems is when there are trees around because the spores tend to stick to the compound and it goes dark pretty quickly, hence the need to clean it a couple of times a year.Overall, a simple solution to grouting.Now, the bad which is the delivery and packaging. I bought this from Amazon but it was a 3rd party seller. No issues there but they were badly packaged and when they arrived I put them aside not noticing that the heavy handed delivery company had knocked one so badly the box was damaged. Which was pretty easy to do because the supplier hadn't packaged them well.Unfortunately, that knock had also damaged the inner pack thus exposing the product to air and thus when I got to use one of the units it was already hard. Too late to make a complaint unfortunately because I never checked on delivery.

Great product great price, and does the job its meant to do, easy and straight forward to use,I never use anything else.

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.

So easy to use and great between slabs in garden, can’t say with longevity but review I read were all good! 😊 garden is looking so much fresher and only used one of the bag so have more for the future - bonus 👍😊Slabs need more cleaning as neglected them a little but so happy with the results

Easy to use, looks ok so far. Shame there were a couple of fist size lumps set solid in the 2nd bag I opened. May look to get a different brand next time. Arrived a day early so that was a bonus.

This is a great option for anyone looking to refresh their patio or paving without breaking the bank hiring a professional. The sand-like consistency (it's a bit like moonsand) is easy to work with, and it sets quickly, even in damp conditions. However, be prepared to put in extra effort to achieve a smooth finish, as the texture can be a bit grainy. Overall, I'm pleased with the result.Pros:- Easy to use, especially for DIY novices.- The texture makes application straightforward.- Cost-effective compared to professional repointing.- Dries quickly and effectively.Cons:- Can be difficult to distinguish between treated and untreated areas during application- Achieving a perfectly smooth finish requires extra effort.- The grainy texture might not be aesthetically pleasing to everyone.I appreciated the clear instructions provided. While a trowel and brush aren't mandatory, they definitely make the job easier.

Used this to fill my natural slab gaps. Really easy to apply. Coarse finish but I don't mind that.Could probably smooth it off if necessary.
