How Do I Get Concrete to Dry Faster?

When you’re working with concrete, drying time matters. Waiting for a slab to dry can feel slow, but there are ways to move it along. Jason explains the steps that help concrete slabs dry faster.

In this video, you’ll learn how to:

• Keep ambient conditions steady and favorable, since temperature and humidity affect how fast concrete dries.
• Move air across the slab with fans to speed up evaporation.
• Run dehumidifiers to pull moisture out of the air.
• Watch the water-to-cement ratio, since too much water in the mix slows drying.
• Avoid overdoing troweling and sealing, which can close up the surface pores and trap moisture.
• Control the space by keeping doors and windows closed and running the HVAC.

Put these together and your next slab can dry faster, with fewer surprises.

For what gets in the way, see how a nine-month-old slab can still be at 95% RH.
