Sika – FastFix All Weather Self-Setting Paving Jointing Compound – Ready To Use – No Mixing Required - Deep Grey – 14kg – 20 sq. m

First time I've used this (or any other jointing compound). The bucket is really heavy (for an old girl like me) so be careful. I jet washed all the old loose mortar out of my patio and made sure to wet the area I was working on. Inside the bucket are two sealed packs - once you open one, it says you can keep it fresh for up to a month if it's under water. Easy to get into the joints. My patio is italian sandstone so the gaps vary from about 5mm wide to about an inch and it worked well on all. You could brush it in, but for longevity, you do need to compact it well into the joints then gently rinse off any residue on the surface. Hasn't left any stains. Looks good so far but it will take me a while to complete.

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, really easy to do and looks great. The company were really good with communication, especially when one pack had not arrived but it was just delivered a day later, which was planned I just missed the note. Fast delivery too - faster than expected.

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.

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.
