Despite the description saying that it is ‘all weather’, I definitely wouldn’t recommend using it in the rain. I don’t want a dark joint (I had old fashioned sand and cement on my previous house with the same sandstone) so what colour jointing would you recommend?

We were not looking forward to using this old method again as very time consuming and wanted a finer looking finish. I used Sika Fastfix brush in grouting compound on my newly layed granite paving slabs, i followed the instuctions to the letter, the grout went very hard and has done the trick, but i have been left with heavy staining on my granite slabs, and it looks really bad, i got in touch with Sika Everbuild, to get advice on the staining, they said the staining was the result of the polymers in the resin, and they dont have another product to remove the stains,they said the staining should go away over time, anything from 1 day to 6 months, if i knew this was going to happen, there is no way I would have used this produced, i am very disapointed with Sika fastfix, and would not advise anyone to use it, Sika should high light the staining problem on the product container. A lot of water needs to be added during application – so it’s best if one person sweeps the compound into the joints whilst the other adds the water.

We often come back the next day with a stiff broom to get the left over residue of jointing compound off the top of the paving slabs as it can be easier to remove when dry. At this point I can only recommend jetwashing the patio with hopes of it blowing out and them replacing it with some new jointing compound. kg packet may not cover quite as much area as you might expect – although it can depend on the size of the gaps between your paving. With a unique formula containing Active Resin Technology for advanced durability it is ready to use with no mixing required, easy to apply in all weather conditions; even in the rain and won’t shrink or crack over time.

I’ve used this product twice, first when it was installed by the landscaper, after pressure washing the slabs 2 years after installation I succeeded in blasting the jointing compound out aswell. I’ve used one bag from the box to try under our new corner sofa so if I have any issues, it will be hidden by the furniture. I am worried the grey would come up either too dark or be a different colour grey to the slab which might look funny? Hi Jay, I personally would joint the paving first, wait a few days for the paving jointing compound to properly set, give it a good clean and finally seal the patio. If you want something that’s easy to use, the Sika FastFix All Weather Self-Setting Paving Jointing Compound doesn’t require any previous grouting knowledge.It comes in various colours, works for multiple surfaces, and you can apply it in any temperature between 5 – 25°C! Hi Sonia, according to the instructions, the joint depth needs to be at least 20mm with a minimum width of 5mm. You may need to keep the paving very wet as you apply the product, or simply apply it straight from the packet. I moved onto damping the tiles as I went along when I noticed staining on the tiles I had done dry, and the wet tiles don’t seem to have stained as bad. This can also happen when we point a patio with a mortar mix instead of the paving jointing compound but as you said, it does fade after a while!
