403 Premium Concrete Hardener and Dustproofer – Clear Coat – 5 Litre

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.

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.

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.

Chose to use this product after reading many of the positive Amazon product reviews, and also considering the price point compared to other products. After laying a 50sq metre concrete garage floor 18 months earlier, it had become very dusty as it has dried out completely. To the point that I could fill half a dustpan with every sweep through. In all I used up 5 x 5 litre containers soaking the floor with a roller over 4 coats every 24 hours apart. As each coat dried the dustproofer became more effective in sealing the dust in. Various areas took longer due to the different top surface condition. 2 days after completing the treatment I gave the floor a thorough washing through with the hosepipe and stiff brush. Only a small amount of unreacted milky water ran off. Now it’s dried out I’m left with a completely dust proof garage floor which is slightly darker that before and with a very light sheen when you look across. The floor is no more slippery than before. Very happy with the result, no more dust in the air or footprints when walking into the house. I would highly recommend this product, but also to follow the application instructions printed on the can for best results. I applied 4 coats with a thick roller every 24 hours which worked well for me with a total cost of less than £100.00

Good product for good price

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.

I was disappointed with this product. Having used a similar version from Wickes on half of the garage floor (which looked great!), I was disappointed when using this on the rest of the floor as it has left a "wet" concrete look to the floor (even when completely dry - it's been over a month since we used this). The Wickes product was more expensive but the end results were much better. It has stopped the dust though, so although the results aren't pretty (well...as pretty as a garage floor can be!!) I guess it did it's job.

Pour le prix, j ’ ai tenté l’achat. L’esperance de résultat me paraissait très faible au regard du prix comparé aux produits concurrents. J ’ ai testé sur une terrasse dont la surface farinait un peu et en marchant dessus, on faisait des traces blanches dans la maison. Dès la première couche le résultat était ’visible’. Après la 2e couche : plus de farine en surface. Plus de problème. Prévoir un bidon pour 20m2. Depuis j’ai racheté un autre bidon pour faire la 2e partie de ma terrasse. J ’ ai passé le produit avec une brosse d’encollage de tapisserie ,rapide. Produit recommandé.

il liquido non da i risultato sperato , fa poco niente , meglio tenersi il denaro, lo sconsiglio, fissa poco o niente

Produit conforme à l'attente. Plus de traces blanches lorsque l'on entre dans la maison. Pas cher et efficace sur beton

Notice en anglais. Pas d'odeur. Produit éfficace en terme de couche de protection et d'imperméabilisation. J'ai appliqué généreusement car il était bien absorbé. Attention cependant si vous souhaitez l'utiliser pour l'intérieur, l'effet est satiné (pour ma part je protège un sol en ragréage fibré que je souhaite laisser brut).

Hydroxyde pour une dalle, très bonne efficacité!
