How soon to start watering concrete?

The article aims to answer the question “How soon to start watering concrete?“. It will also discuss the pros and cons of watering your concrete. 

How soon to start watering concrete?

It is best to start watering your concrete within 10hrs after pouring concrete. If the cure starts just after 12 hrs the water for hydration will be reduced but not too much.

For the first seven days, you should water your concrete five to ten times a day, if you can. This is known as “wet curing,” because it permits the concrete to dry out over time.

In seven days, the concrete reaches 58 percent strength, and in 28 days, 98 percent strength. Curing is therefore very important. 

In order to maintain the strength of the slabs, water must be sluiced over them for at least seven days, and it must be ensured that the water does not dry out. 

At least three times a day, walls should be drenched in water to ensure effective healing. It should be covered in Gunny or strand and kept damp at all times for pillars.

Curing concrete is accomplished by letting water run off the top layer. Concrete curing should not be done with water that is lower than 50 degrees Fahrenheit. 

Using water that is colder than 50°C might cause cracking and failure in concrete because of the hydration reaction. The volumetric variations in concrete caused by drying and wetting the concrete surface eventually lead to cracking.

The development of cracks in the pipe lining will go unnoticed by most people, so extra care should be given when straw curing by using wire mesh and plastering.

Similarly, curing after plastering is vital since it is blood for cement mortar to thicken. Every three hours, for a week, this should be done to keep the exterior wall moist and not dried out. The most care should be taken with the exterior wall curing, as it is prone to drying out.

It’s important to use softened water during the curing process to avoid salt deposits on the walls and concrete.

It is important to keep concrete moist to aid in the curing process. Concrete does not harden as a result of drying; rather, it hardens as a result of a chemical reaction known as hydration.

As long as the concrete has moisture, the hardening or curing process continues. The hardening process might be slowed or halted if the concrete loses too much water through evaporation.

A batch of freshly poured concrete will continue to strengthen for several days or weeks, depending on how long it’s been allowed to “wet cure.”

What is the importance of water in concrete making?

Water is a very important factor in the strength of concrete. Sand, stone, and aggregate are combined in a precise proportion to produce dry concrete. 

Because cement reacts chemically with water, a paste is formed that holds the other materials together. Over a long period of time, water seeps out of the concrete as it cures and hardens. 

Curing is the technical term for this procedure, which usually takes 28 days to complete. When making concrete, one of the most common mistakes is to add too much water. 

A weaker final product can be achieved if the concrete is allowed to dry too long. Structures that rely on solid concrete for their foundations and footings may be doomed. Since this is the case, concrete is mixed as dry as possible by masons, who carefully check the amount of water they use.

Concrete shrinks excessively when it dries if it becomes overly damp. As a result, cracks in the concrete might grow to be so large that they endanger the building.

The fundamental issue with watered-down concrete is not fissures, but rather frailty. Concrete’s compressive strength can be drastically reduced if the mix is too watery. Every inch of droop decreases the compressive strength of concrete by approximately 500 psi. If the concrete is being used to support something substantial, this drop in strength could spell tragedy.

Cracks and breaking can occur when concrete is overly damp, making it more susceptible to failure. To achieve the optimal texture, aim for a thick oatmeal-like consistency that will never be runny or thin.

When concrete dries with too much water, it becomes more prone to cracks and crevices. As a result of the amount of water that needs to be evaporated, this is the case. Since the concrete will soak up more water than it should, the structure will fail.

Why should I water my concrete?

Watering concrete is very important. 

Concrete that has been moist-cured for 20 days has a strength that is more than double that of concrete that has only been moist-cured for four days. The curing process will continue for several months, despite the fact that the largest gains are made in the first week or two.

Moist-cured concrete dries out faster than uncured concrete and is only about half as strong as it could be. Shrinkage cracks will also be more prevalent.

A common way of curing concrete is to cover it with a moisture-retaining fabric, such as burlap, as soon as possible after it has set. During the curing process, the fabric should be maintained wet with a garden hose to ensure that a thin layer of water stays on the concrete’s surface.

Is overly wet concrete a problem?

Yes, the overly wet concrete may be a problem. We need to talk about the ingredients in order to completely appreciate why overly wet concrete can be such an issue. 

A dry powder is the starting point for concrete, a man-made substance. Cement is activated by water, which causes a chemical reaction and the formation of a paste. 

In order to generate extremely durable concrete, the cement paste is mixed with the other materials and then allowed to dry. If you want your concrete to be as strong and lasting as possible, this curing procedure is critical.

It is impossible for the cement to produce a paste without water. If the concrete is allowed to dry, it will become brittle and weak.

When it comes to activating the cement, you only need a small amount of water and nothing more. Adding more water if you have any dry powder in your mixture is necessary. 

The problem is that if your mix is overly moist, it will appear and feel sloppy. Do not forget to use thick oatmeal. You should be able to form a snowball out of the concrete with your hands. If you can feel water seeping into the concrete, it’s too moist.

Concrete that has been watered down is more prone to breaking, cracking, and forming new pores.

Can I spray water on my concrete?

Yes, you can spray water on your concrete. One of the greatest and oldest methods of curing concrete is to spray it with water. Concrete begins to cure after it has been poured and finished. It is recommended to use slow-curing concrete since it will cure more evenly.

The weather outside can get quite scorching in the summer. You can lower the concrete temperature by keeping the surface wet. As soon as possible after waking up, begin sprinkling water over your concrete. 

Do not begin watering the concrete during the hottest portion of the day, as this could cause the surface crazing to develop (similar to a hot glass breaking when filled with cold water).


We know that the chemical reaction between cement and water binds together sand and gravel to form concrete. A correct amount of water must be present in this mixture at all times.

A traditional way to cure concrete is to spray down the surface as often as possible, five to ten times a day, for the first seven days of the curing process. With “wet curing,” moisture in the concrete can be gently evaporated over time.

When water evaporates too quickly, it can cause stress and cracking in the end product. For the first 28 days of construction, the goal is to keep the concrete moist.

Frequently asked questions (FAQS): How soon to start watering concrete?

How soon to start watering concrete?

It is best to start watering your concrete within 10hrs after pouring concrete. If the cure starts just after 12 hrs the water for hydration will be reduced but not too much.

Does watering cure the concrete?

Yes, the curing process is aided by keeping concrete moist. Evaporation can cause concrete to harden too slowly or stop completely. 

For as long as the concrete keeps moisture, it continues to strengthen, but the rate of strength gain slows the longer it remains moist-cured.

What happens if concrete is not watered properly?

Lack of moisture preservation on the exposed horizontal surface of the concrete during the first 24 hours after casting causes plastic shrinkage cracks and a weak and dusty surface. 

This results in a loss of strength that cannot be reversed, and the concrete becomes porous.
