Hydron Mona-Guard Dustproofer


Concrete naturally dusts and powders. If you need a dust-free environment, for example in a cafe, you don`t want your customers getting concrete dust all over their clothes. The Mona-Guard Dustproofer is the ideal way to prevent dusting, while also hardening at the same time, giving a nice smooth finish.

Other Advantages

  • Long-lasting.
  • Reduces oil penetration.
  • Impedes lime efflorescence.

The reduction of dust from untreated concrete floors is important to those who need to keep the environment as dust-free as possible. Concrete naturally dusts and powders, so in environments where dust needs to be kept to a minimum, it is necessary to seal it. This is where the Mona-Guard Dustproofer comes in -- it gives you peace of mind twice over; it's a concrete hardener and a dustproofer, preventing the concrete from naturally dusting, and therefore creating unnecessary and unwanted concrete power moving around the environment.

Product Use in the Workplace

  • Car showroom - Flooring in car showrooms needs to be clean and in such environments which have concrete flooring, it must be borne in mind that concrete naturally dusts, sending waves of concrete-dust over the new cars.
  • Food production plant - The responsibility of preparing food stuffs for human consumption means that all sorts of contaminants needs to be controlled. Concrete flooring for example needs to be sealed-in so that dusting from the concrete does not occur.

Would this be suitable outside and stop water penetrating an old concrete floor?


This product is suitable for internal or external use to reduce the levels of dust, oil and water penetration to a untreated concrete floor.

questions A on 2020-04-08 08:58:48

Can this be used over a kitchen floor that has been sealed using Blackfriar Professional Water Based Floor Sealer? (If no, can you recommend any clear floor coating that could be used in this circumstance?)


Hydron Mona-Guard Dustproofer is formulated primarily for use on cement based screeds and subfloors not on painted surfaces. 

We would recommend removal of the previous coating prior to application.
