Sika – FastFix All Weather Self-Setting Paving Jointing Compound – Ready to Use – No Mixing Required – Flint – 15kg – 18 sq. m

This product is easy to use and effective .

Very easy to use, cheapest I've found on the market. I can only give it four stars as it has only just been used and I do not know it's durability

This is easy to use to repair a patio where some of the grout has come loose leaving holes and cracks around slabs - assuming you can get the lid off the tub. I had to ask a builder and he needed a pair of pliers! Ignore the instructions to brush it over the patio. Use a kneeling pad and work on one crack at a time. Wear latex gloves and use a small plastic scoop (like the ones which come with powdered food supplements or washing powder) and empty a small amount into the crack then push it down firmly with your fingers. It's time consuming but you won't waste loads of product or get it stuck all over your patio. The tub contains 2 separate sealed pouches of product, which is useful as it starts to set after an hour so you need to have got all the product in by then. I found it easy to get through a pouch in under an hour. You will need much more product than you think. I have used 2 tubs already on my driveway and will need to order a third, but I had some very deep gaps between paving slabs. I've found that once done it lasts several years, even though the driveway is on clay so gets quite a lot of movement over the seasons. I used 'dark buff' which blends in nicely with my sandstone slabs.

So easy to use and great finish. Highly recommend

Excellent product looks good when completed

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.

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.

Very easy to use and does the job well
