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

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

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.

Dose what it says on the tub

Bought it Aug 2022. Been using it to fix small cracks and repairs. Mostly on patio cracks and it has all worked really well. Has stayed dry in the box in the shed for 18months, so really happy. One suggestion is to take small quantity out into a small bucket and mix, as the product hardens very quickly. You can always had more water to it and make it get it back to the right consistency. If you end up mixing directly in the bucket, handling that quantity will be touch given how quickly it sets. Personally love the ease and hav just ordered another one to finish of a little piece ending work and store the rest for emergencies.

easy to mix & use but does not expand much

I used this product to mend a garden path and it sets quickly and is a very durable product. It has a fast set time so you need to be aware of time. i would also suggest mixing with water is done outside of the bucket as it can be hard work trying to ensure it is all mixed and there are no dry areas in the mix.Overall it is a really good cement product and waterproof! It is worth buying for small jobs internally or externally.

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