Usually, concrete takes around 28 days to fully cure at maximum strength, but this will obviously vary depending on the nature of the mix and the conditions it’s drying under. The problem is simple: curing can eat up a lot of time if you put certain measures in place, but if you don’t wait long enough, structural failures will inevitably cause further delays anyway. So, to properly boost the efficiency of your project, you need to find ways of speeding up concrete drying which don’t compromise the drying process itself.

Weather is a factor

If your concrete is exposed to the elements, you won’t be surprised to learn that the concrete will dry faster in warmer, sunnier conditions. While this isn’t always an option, choosing to start your project in summer is a surefire way to minimise curing time. Of course, if summer isn’t an option, try to avoid exceedingly low temperatures or extended periods of rain.

Using a heater

Of course, we don’t all have the luxury of choosing when our projects begin and end, so you can always use a heater for some artificial sun. Whether you use a heater or heating mats, be careful not to overheat the concrete. A gentle amount of heat should be enough to speed up the drying time without compromising the mix.

Using warm water

As an essential ingredient in any concrete mix, water plays an important role in the curing process and can affect curing times in a number of ways. For example, if you use slightly warmer water in your concrete mix, you can encourage a quicker reaction and, in turn, a quicker curing time. Avoid water that’s too hot or boiling, however, as this will only serve to damage the mix.

Reducing the amount of water

The amount of water added to a concrete mix is crucial, especially if you’re trying to minimise drying time. This is because the more water you add to a mix, the longer the concrete will take to set. However, be careful not to put too little in either, as this can make the mix too thick and will ultimately compromise its strength. To limit the amount of water your mix has, you could always opt for a water reducer. They are from the same family as retarders and can reduce the water content of a mix by 5-10% and increase the workability of the concrete.

Avoid hard trowelling

Too much trowelling can cause densification of the concrete, collapsing air pockets and vents. This is an issue because it prevents the moisture from escaping during the drying process which, of course, will extend the drying time. Whether you’re pouring in hot or cold weather, the quality of your concrete is crucial, and EasyMix supply the highest standard of product for customers throughout London in the domestic and commercial markets.

What will draw moisture out?

Baking Soda Get a small bowl that will fit in the area you'd like to place it in. Fill the bowl full of baking soda. Place the bowl in the area you'd like to dehumidify. The baking soda will harden as it absorbs moisture, and at that time, you'll want to replace it with fresh baking soda.

Rock Salt

The most popular DIY dehumidifier is the one that works the best—rock salt. Rock salt naturally absorbs moisture out of the air, making it a great choice to use as a dehumidifier. To make a rock salt humidifier, you'll need a large bag of rock salt (also sometimes referred to as sodium chloride) and two 5-gallon buckets. You should be able to find both at a hardware store.

Here's how to make it:

Drill several small holes in one of the buckets along the sides and the bottom. Put the bucket with the holes inside the other bucket. Fill the bucket all the way up to the top with rock salt. Place the bucket in the area of your home you'd like to dehumidify. The bucket will begin to collect water, and that water will drip through the holes of the inside bucket. The water will then collect inside the outer bucket, trapping excess moisture.
