Bostik Cementone Waterproof Rapid Setting Cement

I bought this as we had 2 small holes around the edges of the deep kitchen drain which was discovered by the professional who came to unblock it. He said we needed to get it repaired to prevent the waste water damaging our foundations. I mixed up a small quantity of the mixture in an old plastic pot and stirred it with an old gardening knife. It mixed up like icing sugar. I got it to a stiff consistency and filled up the gaps. To ensure it dried I used a hairdryer on it for a while, and did not use the drain for a couple of hours. The product is very easy to use, and as I wore plastic gloves made no mess. I never bother to check sizes and assumed when I ordered the product it would come in a small pot. The container is huge, and I could hardly lift it. I will embark on further filling on the garden path , weather permitting, and will offer some to my neighbour as she may wish to use some. This is a truly excellent product, easy to use, and very good value.

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.

Good job. Easy to use.

I bought this for pointing up my outside walls it's very quiet drying so make sure you do what you doing quickly texture is good and it glue quality is good I would definitely recommend using this for doing your pointing up

Bostik Cementone Rapid Setting Cement is a quick and convenient solution for various cementing projects. This cement offers rapid setting times, allowing for faster completion of tasks. It is easy to mix and apply, making it suitable for both professionals and DIY enthusiasts. One of the notable features of this cement is its fast setting time. It quickly hardens, which is beneficial for time-sensitive projects or situations where you need a quick fix. It also provides good initial strength, ensuring a solid bond once it sets. The cement's versatility is another advantage. It can be used for a wide range of applications, such as patching cracks in concrete, setting fence posts, or repairing damaged surfaces. Its durability and resistance to water make it suitable for both interior and exterior projects. However, it's worth noting that the rapid setting nature of this cement leaves less time for adjustments or corrections. Once it starts to set, it becomes difficult to manipulate or reposition. Additionally, the rapid setting time can be a disadvantage if you require more working time or have complex projects that demand precise adjustments. Overall, Bostik Cementone Rapid Setting Cement is a reliable option for quick cementing needs. Its fast setting time and versatility make it a convenient choice, but it may not be suitable for projects that require extended working time or intricate adjustments.

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.

Excellent! does what it says on the bucket.

Ce n’est pas très pratique. Il est impossible de mélanger tout le ciment à l’eau sauf à utiliser un mélangeur mécanique. Et la prise est très rapide.
