Sika – FastFix All Weather Self-Setting Paving Jointing Compound – Ready to Use – No Mixing Required – Dark Buff – 15kg – 21 sq. m

This is really excellent stuff. Very straightforward to apply if you just take your time and follow the instructions. I compacted it firmly between patio slabs and using a thin piece of wood, carefully it smoothed off. To get a really smooth finish just get on some rubber gloves, sprinkle some water over the grout lines and gently rub over. The water causes the mixture to become more soluble and then it settles to a smooth finish as the water drains away. No staining of the slabs either which is a massive bonus. I haven't had a chance to really test its durability but so far it looks great and I'm very happy.

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.

I followed the advice on using the product. I expected to have to work faster due to my understanding it went solid very quickly. I worked it in using a slab at a time brushed mix into joint pressed down with a pointed trowel brushed more mix then pressed in with a rounded trowel. It never hardened right away and at the end of 5 hours. Must admit I was concerned it didn’t work but after ignoring it and not checking it for hardening I am pleased to say 3 days later all is well and it has set now. Looks fine so hopefully it lasts for a decent length of time. Follow instructions and be patient working with it correctly and waiting for it to set.

⭐️⭐️⭐️⭐️⭐️ Bought two tubes of Sika FastFix All Weather Self-Setting Paving Jointing Compound, and I’m really impressed with the results. It’s so easy to use — no mixing required, just brush it into the joints, compact it down, and let it set. The finish looks clean and professional with minimal effort. Even better, it works perfectly in all weather conditions, which makes it ideal for the UK! I used it between patio slabs, and it’s hardened nicely without cracking or washing out. The colour stays consistent, and the overall look is neat and tidy. Great value for money, saves a lot of time compared to traditional mortar, and gives long-lasting results. Would definitely buy again — excellent product from Sika!

Whilst the product that was usable was very good- looks good and apparently easy to use so I’d give a 5 star review for the product that was usable. Unfortunately I’d booked someone to come & redo the grout using this product. However when he came to use it one half of one tub had hardened and was unusable. The work was therefore not able to be completed & I then had to rebook someone to complete the job when I’d bought more of the product. Ended up costing me in man hours & an extra tub of the product. I messaged the seller via Amazon not even had the decency of a reply. Disappointing.

Really worked well,abit of cleaning up to do after,but overall pleased With the results.

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.
