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: Great product, massively reduces the dust from a concrete floor. - I ordered this to counter the dust on the garage floor. This was by far the most cost effective solution. One bottle covers a standard garage two or three times. Just sweep out the garage, fill a paint tray and use a roller to apply. The first coat was quickly absorbed and I found I used about two thirds of the bottle. This quickly dried and I pretty much just put another coat on straight away. You can see this is absorbed much less and goes on much more easily than the first coat. After that I just put everything back in the garage. It product itself is quite watery but doors the job. Very little dust when I sweep out the garage.

## 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

### ⭐⭐⭐⭐ Does work but you may need a lot more than you think
*by R***S on 13 May 2021*

I have a double garage (circa 27m2) attached to my brand new build house and after reading the generally reviews for this product, I thought I'd give it a go. I initially bought 1x 5 litre bottle but after reading the reviews again and also the instructions on the back of the bottle, decided to get a second on order more or less straight away after it arrived. I split the garage in two and moved everything from one side to the other so I had a good 60% of the garage to work on. First coat really got sucked in to the floor, as did the second. It would be easy to stop at the second coat and think the product isn't up to the job as the finish was really patchy. Some areas had hardened well but others were still dusty to touch. I persevered and cracked open the second bottle and used pretty much all of that as well. In the end, the floor had 3 full coats then 2 patch coats to fill in the gaps where I was still detecting dusty residue on my finger tips. After these have now gone off fully, I've got the whole floor sealed without any patchy areas. I've ordered two more 5 litre bottles now in order to complete the other half of the garage in the next few days. So in summary, it does work but you've got to be really liberal with the coats. I used a brush and on reflection, I think not enough was going down on each coat. You almost need to have the floor completely soaked/sodden as the concrete will really suck it all up. Finish looks good now though so would recommend.
