Bostik Rapid 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.

This is a fantastic product but there are two important things to be aware of:1. This stuff dries instantly! I added water into my mixing pot and it set almost instantly. Make sure you mix this in small batches right next to what your fixing.2. The tub is small. It’s just enough to do a repair, but not enough to fill a large hole or fix a front door step.Other than that, it’s great stuff and sets strong as long as it’s added in thick amounts. Lightly applied amounts will just crumble and fall off.

Worth waiting for. I have a small paver on the drive that had become loose. I did try to secure it with strong glue but that did not work. This did. Product handily comes in a mixing bucket and with careful application of water it was ready for application. The paver is now secure.

Worked a treat, mix with water, dries in 2 hours, but leave until next day if its for a rotary washing line.

Will definitely use this again. Set fast and strong.

Why did you choose this product over others?:Great and easy to use

Had some water penetration into garage and need to seal the foundation.Decided to use this product.Easy to mix and use, it is very sensitive to amount of water added, so go carefully.It does set quickly, even where the area is damp and it has certainly met my initial requirements.Lets see if it has sealed things up and remains effective over time.

This is an excellent product but I had several small repairs and even though I prepared them all in advance the cement hardened quickly in the bucket before I could complete all the jobs I needed to do. Results were great but next time I would remove smaller amounts from the bucket and mix what I need.
