Have you ever experienced or heard of the phenomena of concrete sweating? Concrete sweating is often times mistaken for a water problem since it is common to see a condensation effect on the surface of the slab. Continue reading to learn how to prevent and reduce concrete sweating.
What causes concrete to sweat?
When warm air comes into contact with a colder temperature concrete slab, the condensation will build up on the surface and can commonly be defined as concrete sweating. The combination of temperature swings and humidity build up cause the concrete to sweat.
How do you prevent concrete sweating?
- Dry out the room by air movement: a high volume low speed fan works well.
- Turn down the air conditioning/turn up the heat to keep the concrete floor temperature and the air temperature at similiar levels.
- Use a dehumidifier to remove moisture from the air and reduce the condensation.
- Use a penetrating sealer to seal the concrete and keep out moisture.
"Mold and mildew are a result of concrete sweating so using a penetrating concrete sealer at the first signs of concrete sweating is ideal."
One of the best solutions to combat concrete sweating is to use SEMCO Natural Shield. SEMCO Natural Shield fills into the pores of the substrate, in which chemical reaction follows, that creates a solid, but breathable membrane and provides long lasting protection for a vast array of surfaces in which it leaves a natural finish. Additionally the Natural Shield keeps out oils and greases while simultaneously eliminating staining.
