## Questions & Answers

**Q: Has anyone used this on porcelain paving slabs?**
A: It works perfectly fine as long as the joint is 5mm or larger. Ensure the paving is damp so the pointing doesn’t stick to the surface

**Q: I bought this and used it on my path which has now set, but need more as it's not high enough and gaps. Can I put more ontop of set Sika??**
A: I did this and it was fine, i just made sure it was well compressed, it has not separated so far after 2 years. It generally does seem to attract moss which nobody has mentioned.

**Q: Can this be used to repoint already pointed Indian sand stone where grouting has come off ..?**
A: You need to rake out all the existing pointing before repointing and push the Sika Fastfix into the open joints with a pointing trowel.

**Q: how many bags will I need to do 120 slabs?**
A: Everything depends on the width and depth of your joints,each box is supposed to do 20 sq metres but I found that I had to buy six bikes to do my 60 sq metres. Expensive but I think worth it for ease of use and hopefully durability.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by B***7 on 1 July 2026*

This product is easy to use and effective .

### ⭐⭐⭐⭐ Looks good and easy to use
*by A***R on 14 June 2026*

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

### ⭐⭐⭐⭐⭐ Great for repairing patios/drives
*by J***O on 4 July 2026*

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.
