How to really get rid of mold on a concrete floor


If you have an old concrete floor in your home or cottage, then you know from your own experience that a concrete floor loses quality over time. They crack or become lumpy and mold begins to appear in them. A cracked floor is difficult to wipe down and there’s no sense trying to deal with mold with a sharp stream of water. It’s just a one-time help, not a real solution. Are you still troubled by recurring mold? Read a few tips about how to make the fight with mold easier.

Cracks and mold on a concrete floor are completely normal occurrences that happen indoors and outdoors. Not only does it not look aesthetically nice, but mold also represents a health hazard. It causes allergies, eye inflammation, asthma, pain in the joints, respiratory tract inflammation, and some types are even responsible for pneumonia and subsequent death. It’s therefore in your interest to get rid of it the best way possible, whether the fight with it takes you to your garage, cottage, weekend home or terrace.

First, you must clean the floor

It’s certain that only cleaning a concrete floor has no lasting effect. But this is the step you have to begin with. There are many options for how to do it. The completely easiest way is to use a sharp stream of water, but then it will be a long time before the concrete dries out. Unless you are able to adequately ventilate the spaces, the mold will continue to grow merrily along.

Alternative options include a variety of chemical products, using a steam cleaning machine or products ordinarily used in the household. You can also use bleach or vinegar to fight mold, but you mustn’t dilute them. You have to be very careful working with bleach, because it can cause respiratory irritation. Probably the most reliable solution is to use a chemical agent designed specifically to remove mold.

The problem, however, doesn’t end there. What to do after removing mold so that it doesn’t reappear?


A penetrating coating, or primer, is an economical option

If you’re looking for a readily available solution, then a primer is for you. Before applying it, the floor needs to be properly dried out, otherwise you will create for your-self more worries than good. It will be sucked into the dry concrete, seal it and prevent the future growth of mold and mildew.

Primers cost only a couple hundred crowns and can be applied without any outside help. However, they will not help you much if you need to level off a surface that is completely fractured. In this case, you will need to also apply a top coat.

A cement screed is not recommended for a damp substrate

If in the past you encountered a concrete floor with a great deal of moisture, then a cement screed is absolutely not the way to go. A top coat will seal the surface of the concrete and prevent the moisture from evaporating. Over time the surface will begin to peel and the mold will continue to grow.

If you would like to apply a concrete screed, it’s good to insulate the concrete against moisture and properly dry out the foundation. It’s an effective solution that frees you from unevenness and bumps in the surface.

Important is not to seal moisture with tiles

If you decide to put another layer on concrete, tiling becomes another foundation. But you just can’t put it on the floor like that. Best is to first apply a primer or to insulate the concrete floor to reduce the absorption of the material. Otherwise, mold-inducing moisture could again get back into the concrete.

The underside of Fortelock floor tiles

If you’re looking for a solution for a steadily damp room, Fortelock PVC floor tiles can provide you a better service. It has a unique bottom-side system of drainage channels that work against moisture. And no moisture means no mold. In addition, PVC floor tiles are considered the floating variety, so it’s no problem to disassemble the floor any time, let the concrete dry out, perhaps apply another coat of anti-mold primer, and reinstall the tiles. You won’t be able to do this with ceramic tiles.

What flooring is the best so mildew never occurs?

You’re worried that mildew can damage your health. Don’t hesitate and invest a bit more money. Forget about any primer, which doesn’t help much anyway. It’s better not to risk it either with a cement screed, because as soon as you seal the floor, you never know what’s going on inside there until the top layer begins to crack. Something similar will happen with ceramic tiles. But if you have faith in primers, they could work providing you don’t live in an area plagued by flooding. It would really be better to have flooring that you can take apart, dry out and reinstall.

Fortelock PVC floor tiles allow you to take the tiles apart any time and see whether you’re winning the war against mold. In any event, it’s good to apply primer beneath PVC tiles. You should do everything possible to prevent mildew from having the slightest chance to grow. Your reward will be a wholesome floor and good health.
