Bostik Rapid Setting Cement – 10kg – Fast-Setting 20min, Waterproof & Strong – Ideal for Patching, Drain Repairs & Concrete Fixing – Interior & Exterior Use

Did the trick for me. Didn't need a whole lot and don't have a car but this helped me patch render in my wall. 4:1 sand to cement for base holes and 5:1 for outer layer with some silkabond (also available on Amazon) for plasticity. It's very fine so cover nose and mouth with mask when scooping.

Very easy to mix by hand and sets in 30 minutes.

A very fast setting repair cement , dries to extremely hard surface and water resistance good, would buy again

Great for doing my paths in the garden value for money

good stff

Great thank you

This item does what is says on the tin but you have to use it very quickly as the setting time is very short so you have to work only small areas at a time

The patio at the side of the house was laid badly where the motar was not of recommended mix during the winter months. Unknown to us it was virtuyally all sand with only a skim of cement mixture at very top. Therefore needed scoop it all out and re-point with proper mixture of cement & motar.Instead of using standard pack of 25kg cement at <£5, decided to use this as it is pre-mixed (but not ready-mixed; the user has to add water).By chance I ordered 3. This allowed most of the first bucket to be put into buckets 2 and 3 and leave 1kg or 2 kg in the first bucket with which to mix in some water. For the task above I could only manage to dig out on average 5 feet of old material between the slabs then re-point using this Bostik cement.This Bostik is expensive as compared to standard bag of cement but it is quick setting; strong enough for me to step on the slabs the next day to continue the task of repointing the other slabs. I have also a bucket of Blue Circle Extra Quck Setting cement, which is even more expensive, but which proved to be too quick setting for me to use - a professional brick layer may be proficiently fast to use that Blue Circle Extra Quick cement.I must also say it is mostly cement rather than a motar mixture. Also, depended how (quick or much) you use it, I could only use 1-2 kg at a time, some parts have dried white in colour, some sandy white, some light grey. At the moment noticed it tended to be sandy white from material at the bottom of the bucket - assuming heavier sand sunk to the bottom than the cement p;owder which stayed at the top of the bucket.After comparing with rest of the available versions of cement and different brands, conclusion is it may be expensive but fair as compared to standard and Extra Quick cement. It is also convenient to use; it is quick enough for me to continue work next day but slow enough for my lack of builders' skills (I am better at carpentry). More importantly, during this continued pandemic times, this remains available some of the time whereas standard bags of cement is like gold dust for their non-availability.
