Review: Works really well - I ended up pouring my concrete garage floor in the rain, as the concrete pump and cement mixer were already on site. The result was that the surface ended up really powdery after it had cured. After reading reviews of this product, I ordered much more than I thought I needed, as everyone seemed to say it needed lots of coats and it really soaked in. They were right about soaking in... in the worst places the concrete was like a powdery sponge. In the end I poured it on and brushed it about with the brush from a dustpan and brush set. Most of the floor needed only one coat and the worst areas two. 2 packs of this covered 5.4m by 5.4m. The result is brilliant. No more powdery floor and it has not altered the look of the concrete one bit. Well worth the money and really easy to use.
Review: Works well - This product has worked perfectly in solving the cement dust problem in my garage. I applied it with a long handled roller straight onto the cement screed surface and it has hardened the surface which previously had cement dust raising and getting onto shoes etc. I used two applications in 23ft x 20ft floor and it took just one container. Really good product.

## Questions & Answers

**Q: how important is it to rinse off after final application,as will be difficult owing to location**
A: I applied two coats to a garage floor as recommended, and there was nothing to rinse off.

**Q: Has anyone painted their garage floor after putting this hardener on it, as I am scared any future paint job may not adhere to the floor**
A: If the floor is clean it bonds well. You can paint over it. I find that any water, even from shoes that have walked over wet grass will cause the application to de-bond, creating the white powder described by others.
If you wipe your feet, etc. the bonding in this product stays. However, walking on it (are they surprised that people do this on concrete) causes dulling of the surface, giving an appearance that its not effective. I even took pictures and sent them to the Manufacturer who advises a wipe down should resolve the issue (which it does, as it removes the coating!). 

The only solution is to regularly re-apply another layer, meaning continual expense which is good for everbuild.

The garage of my house was concreted without an anti-dust additive included. There are some parts of the floor that just soak the sealant up - i have noted it i.e. underneath a pallet where no water or people ever go. Once its applied you are stuck with it and it can turn to glue if moisture gets between the floor surface and an object.

**Q: can it be used outdoors**
A: Sorry a bit late but yes it say suitable for interior and exterior surfaces.

**Q: Hi. Does this stuff dry to a gloss finish and if so is it slippy when wet. Thanks**
A: No it was absorbed into the concrete and didn't leave a shine

### ⭐⭐⭐⭐ My very dusty garage floor with rising moisture
*by S***. on 12 March 2025*

After applying 2 coats, it worked very well to stop all the dust. There are still some minor stone chipping due to my damaged concrete floor, which was caused by years of underground moisture, and I can live with that. But I am struggling to find a product that I can apply on top of the treated floor to stop the rising moisture that is causing a lot of condensation on almost everything I place close to the floor, including my washing machine and tumble dryer. Also, some areas with the most moisture appear to have caused some white crystallization power on the surface repeatedly. And for some area I've treated just outside my garage, the whole area turned white. It seems it is not suitable for outdoor use at all. As the instruction specifically states, I cannot paint over the hardened floor, it now leaves me clueless on how to address the moisture issue. I wish their instruction could include advice on handling such a situation. Simply telling us we cannot paint over is not that helpful. I'm all ears if someone has tried to moisture seal their floor after hardening. Nevertheless, for dust-proofing only it works great at such an affordable price.
