Bostik Cementone Rapid Setting Cement

This is a very good product provided that you follow the mixing instructions which are on the container TO THE LETTER. I used it to install a protective cover over an existing water meter manhole. This was done on a damp day at a temperature of 12 degrees Celsius. The mixture has a very creamy consistency but you only have about 20 minutes before it starts to set. Very good for filling in cracks on flat surfaces, but a bit too runny to lay bricks.

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.

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.

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.

Great. Needed a quick easy alternative to fix my washing line pole that broke in a bad storm. Without having to dig up the concrete already in so i purchased this and set the washing pole in the bucket. Its held in in place so far in the couple of months ive done it. Its worked really well actually. Was also easy enough for me to do. I just took off the handle and once set buried the bucket so the pole was back to ground level. Good quality so far and its stuck firm!

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

Rapid setting dry mix cement ideal for drive patching

Easy to use cement and very handy to keep at hand.

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.
