## Description

Multicrete Concrete Hardener & Dustproofer is a low viscosity, premium grade chemical, specifically formulated to seal and harden concrete surfaces. Uses: Seals and hardens concrete floors by penetrating into the concrete to give a robust non-dusting surface with improved resistance to oil and grease. Multicrete CONCRETE HARDENER & DUSTPROOFER is ideal for use in garage workshops and factories with both newly fitted or existing concrete floors. Application: It is essential to wear protective gloves, boots and goggles at all times during application. Surfaces must be clean, dry and free from oil, grease, paint or polish to maximise the effectiveness of this product. If prior cleaning is necessary, use Multicrete BRICK & PATIO CLEANER to remove any stains or grease before washing down and applying Multicrete CONCRETE HARDENER AND DUSTPROOFER. Apply evenly at a ratio of 3-5m² per litre. Use a brush with a firm action to ensure that the product is worked well into the concrete and no puddles form. Two coats will normally suffice but allow the first coat to dry overnight before applying the second. Further coats can be applied if necessary but always allow time for the previous coat to dry sufficiently before application. NB. Leave at least 24 hours before washing down. Limitations: Multicrete CONCRETE HARDENER AND DUSTPROOFER is not designed to restore damaged concrete. Not for use on stonework or coloured concrete. Must not be used on concrete that is less than 28 days old. Storage Conditions: Store in cool, dry conditions in a sealed container between 5 & 30 Degrees C. Protect from freezing. Shelf Life: Up to 24 months when stored according to manufacturer’s instructions. Coverage: 3-5m² per litre, depending on porosity.

Review: For a garage floor - don't bother! - I bought this to seal my double-garage concrete floor. I cleaned and vacuumed the floor before application, and it was VERY easy to apply because it's like water... I used a backpack sprayer and carefully applied all 25lt of the product. Once dried the floor looked no different and I wouldn't say there's much difference in terms of dust. I've now ordered a proper epoxy resin floor coating as I don't believe this product has been very effective at all. If you're sealing a garage floor - save your money, and put it towards a proper floor covering product. I think a PVA and water solution would have been more effective than this. Felt like a waste of money (and time!).
Review: TOTALLY RUBBISH - Used this on my garage floor. What a waste of money and more importantly the time it took to clear my garage, apply, wait and refill garage. Useless product no difference at all after applying 50 ptrs to my garage floor. AVOID THIS PRODUCT !!!

## Questions & Answers

**Q: Can One use Garage paint over this hardener?**
A: Yes - this stuff soaks into the concrete - once you've allowed it time to dry, it should be fine to paint over

**Q: can it be used on peeling painted concrete floors**
A: If you remove loose material first.

**Q: Is it suitable for concrete drive**
A: On a very dry day.

**Q: How important is washing down? I have a lip in the garage door which will stop it flow away**
A: What do you mean by washing down

I used a roller on a long pole to apply it

That sid, it never achieved the result I was after in any case. The concrete still remained dusty as before

### ⭐⭐⭐⭐⭐ Worked perfectly
*by D***N on 22 September 2022*

New garage concrete floor was so so dusty it was a total nightmare. Two coats of the solution made a massive difference. Just beware that you can't use this on concrete until at least 28 days after being laid.
