Apply a 2’x2′ sheet of plastic to the garage floor. Tape down the edges with duct tape and let set for 24 hours. If water droplets form on the inside of the plastic or concrete appears wet (darker in color), moisture is trapped in the floor and Rust-Oleum Moisture Stop should be used prior to coating.
Does Sealing Concrete Stop Moisture?
Concrete’s porous nature means that water from under your home can seep up through your concrete floor, making it damp. Sealing the concrete can help eliminate the dampness on your floor.
How Do You Paint Indoor Concrete Floors?

Low-permeance Vapor Barrier or Retarder. A Low-permeance vapor Barrier or retarder can effectively keep below-slab moisture from reaching the flooring system. Allow Natural Drying of Concrete Slab. Keep Excavation Free of Water.
How Long Does Moisture Stay In Concrete?
An Untreated Slab With No Moisture From The Top Or From Below Will Take 60 To 90 Days To Adequately Dry At 72?
F and 50 % relative humidity. Curing compounds or cold weather can slow this process. If the moisture level in the air is high, water in the concrete evaporates very slowly, or not at all.
How Do You Know If Concrete Is Dry Enough To Seal?
After letting it sit for 24 hours, peel it up and look for any condensation on the underside of the plastic or look for a dark spot on the surface of the concrete. Water on the underside of the plastic or a dark spot on the concrete is created from moisture. If none exists, then you should be fine.
Can Water Seep Up Through Concrete?
Rainwater, melting snow or groundwater can saturate the soil around your foundation and leak in. Water can leak through cracks, or it can penetrate porous concrete or masonry walls in the form of water vapor. Moisture behind the foil means moisture is leaking through the walls.

What If It Rains After Sealing Concrete?
Explanation: The sealer must be dry before it rains or it may wash off. Explanation: Yes rain can wash the sealer off if it rains right after its put on. Normally we like to allow at least 24 hours before any rain but we use additives that can allow us to speed up the curing process.
How Many Coats Of Sealer Can You Put On Concrete?
Concrete sealers are best applied in two thin coats. The first coat of sealer acts like a primer. Most of it will disappear into the concrete surface, and the concrete will probably look fairly unattractive after the first coat. The second thin coat will provide an even finish, color enhancement and gloss.
Why Is Water Coming Up Through Concrete Floor?
When it rains, water is absorbed into the ground until the earth is too saturated to soak up any more water. At this point, the water will begin to rise to the surface, causing hydrostatic pressure to build up against your foundation and basement floors, which leads directly to water seepage into your home.
Why Is Water Coming Up Through The Floor?
Common causes are leaks in the ceiling or a crack in the exterior of the home which both permit water to enter. If the water is seeping up through the floor, it could be a result of insufficiently-sealed foundations or there could be cracks in the foundation floor.
What Causes Moisture In Concrete Slab?
Humidity—warm and humid air condenses into surface moisture when it comes into contact with the cool surface of your concrete floor or slab.
