Concrete Floor Drying Time
Apply the second coat at full strength by brush or quarter inch nap roller.
Concrete floor drying time. However you ve already seen that numerous factors affect how much time a concrete slab needs to dry. After the concrete is poured and floated the curing process ensures it hardens properly. After that you can walk on it.
However as we pointed out above the conditions need to be right. 28 days at this point the concrete should be fully cured. In standard industrial cases full strength concrete is recognized at 28 days.
At seven days you should have concrete that is cured to 70 full strength or greater. We want all the cement paste to react with water and glue the aggregates fa and ca together. Drying time between coats about 1 3 hours drying time final coat 10 hours minimum to 24 hours or more in colder weather or more humid weather.
The longer you allow concrete to cure the harder it becomes. 7 days after partial curing traffic from vehicles and equipment is okay. The general rule of thumb is that concrete takes about 30 days to dry for every one inch of slab thickness.
That is you ll need low ambient relative humidity and a consistently warm temperature. When using 2 or more containers of the same color of drylok concrete floor paint mix them together to ensure color uniformity. Concrete is a top choice for driveways because once it is properly cured it can last for up to 50 years.
Temperatures again cold and frosty weather can make drying concrete inside an unheated building difficult with the natural process of drying taking longer. Allow the first coat to dry for 4 hours prior to applying the second coat. Wet concrete will dry within few hours but do we really want our concrete to be dry.
