BostikRapid Setting Cement | 2.5kg | Fast-Setting 20min | Waterproof & Strong | Ideal for Patching | Drain Repairs & Concrete Fixing | Interior & Exterior Use

Great product. Easy to use and solid once dry.I bought this to fill some cracks and holes on a doorstep. The repairs varied, with some being quite deep holes and others just thinner surface cracks. The cement was simple to mix and ready to use within seconds. Once in position, the instructions said it would set in 20 minutes. In reality, it took a bit longer, even on the more shallow areas, but after about 40 minutes to an hour it was solid and ready to be sealed and painted.If you don’t need the full tub in one go, I’d recommend mixing in a separate container so you can keep the rest for later.The cement has now been in place for over three weeks and it seems strong and durable.

Tips from a first time user and DIY novice...Do not attempt to mix this full tub by hand, I seriously doubt it's possible. My lad tried, he's a big strong lad and there was no way he could get it all mixed with a trowel.You need a drill with a mixing attachment, or even some thick rubber gloves that cover your arms so you can get your hands right in there (do not do that without protection). Otherwise, get a bucket and mix a little at a time.Don't forget you need a mask and eye protection, as soon as we opened the tub there was a cloud of it.We managed to mix the top half of the tub, then there was an unusable layer and still some powder at the bottom, a waste but it was user error.The product itself is great, but it should come with better instructions for those who are inexperienced.I will be buying more to finish the job.

Great product. Love it very easy to use

So easy to use just mix with water. Only mix a small amount at a time though as dries so fast and it would be unusable. Sets really hard. If I can use it at nearly 81 anybody can use it! 🙂

Came promptly, well sealed and unbroken.I found it much easier to mix a little at a time in a bucket as it does set quickly and I needed it for multiple little jobs. i cemented in a new drain cover, fixed some cracks in the patio, fixed some loose bricks and: secured loose capstones on my garden wall. Sorted!

Great product but sets very quickly!! Only mix small batches unless you are the fastest brick layer in town!!

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.

Easy to use and does the job
