Does concrete sealer prevent mold and mildew?
Small cracks or grooves in concrete, brick, or asphalt are perfect places for mold because it can use rainwater to live and grow.

Dry surfaces are less inviting for mold and mildew.

How to tell if concrete is mold or efflorescence?
It’s difficult to determine from the photo whether this is mold or efflorescence. An easy way to distinguish between the two is by flicking a bit of water on the surface. Efflorescence will dissolve in water, mold will just mat down a bit. Either way, it likely indicates vapor emissions moving through the concrete.
What is efflorescence in concrete?
Efflorescence occurs when moisture migrates through the concrete, picking up minerals along the way. Once the moisture reaches the surface, the water evaporates, leaving behind the mineral deposits. Because this is a product of water movement, often a small amount of mold growth is present as well.
What does white growth on concrete mean?
You can verify this by spraying a bit of water on the suspected growth. If it’s efflorescence , it will disappear as the crystals are dissolved by the water. If it’s mold, it will flatten, but remain visible.
What are the two main elements that mold needs to grow?
Mold requires two primary elements for growth – food and moisture . Although concrete is not directly a food source, the thin layer of dust that settles on the surface provides plenty of nutrients. Unless you’re willing to regularly wipe down your concrete, it will be impossible to eliminate the food source for mold.
What happens when water evaporates from concrete?
As the water evaporates at the surface, the salts and minerals are left behind, leaving a crystalline growth.
Why seal concrete?
Sealing the concrete will help eliminate any possibilities of moisture damage – and in turn, help add more durability and strength to the material. They also help keep the concrete visually appealing, preserving the original color and glimmer.
Why use concrete sealer?
Because of the porous nature of the material, it can't do anything about the excess moisture build-up inside .
How long does a concrete driveway last?
The average life of a concrete driveway is approximately 28 to 33 years. However, if the material suffers constant damage, cracking and discoloration – you may find yourself replacing it sooner then you may have imagined.
What happens if concrete isn't dry?
That mainly happens if the concrete laid isn't allowed to dry and strengthened adequately. There will be a lot of cracks showing, right up on the surface of the material. The process is also called "crazing," the cracks aren't big and are narrow. You can quickly service the damage provided it is on time.
What happens if you leave concrete unrepaired?
If left unchecked or unrepaired, the disintegration will lead to severe damage.
What happens when water seeps into concrete?
After the water seeps into the concrete slab via tiny cracks, it freezes in the joints. After that happens, the moisture begins to expand at a rapid pace – by approximately 9%. Now what that does is exert a tremendous amount of pressure on the material leading to crack formation and rupture.
How long does it take for concrete to compress?
If you place the concrete at standard temperatures, it takes an entire day (24-hours) for the material to harness a 500-psi compressive strength.
Why do you put sealer on concrete?
Adding a sealer preserves the look and longevity of the concrete while bringing out its rich color. Sealer will prevent water from absorbing into the concrete by beading it on the surface. This helps concrete last longer, especially in winter. And a good sealer can have non slip additives which is great around a pool.
Why do you need to seal a concrete wall?
After concrete has been poured and cured, adding a sealer helps protect it from future damage, corrosion, and stains. Because concrete is porous, it tends to absorb water and other substances.
How long does it take for a concrete sealer to cure?
Other reactive penetrating sealers (silanes and siloxanes) and most high-performance coatings, such as epoxies and urethanes, should only be applied after the concrete is fully cured (generally 28 days). Almost all sealers can be applied after the concrete is 28 days old.
Why are sealers invisible?
Most chemically reactive sealers are nearly invisible because they penetrate into the concrete. Also any sealer with a flat or matte finish can’t be seen once it’s dry. Solvent-based acrylic resin sealers and epoxies provide significant color enhancement and give concrete a glossy wet look.
How long does it take to seal concrete?

What is a penetrating sealer?
Penetrating. Penetrating sealers seal the pores of concrete below the surface. They form a chemical barrier that shields against intrusion by moisture and chemicals such as ice melt products. Most of these sealers provide invisible protection without changing the appearance of the surface.
What are the enemies of concrete?
Moisture and salt are two of concrete’s biggest enemies. Concrete’s porous texture allows moisture intrusion that causes cracks during freeze-thaw cycles. Salt from ice melt, lawn chemicals, sea spray, and other sources corrodes and weakens concrete. The best way to keep these elements from damaging your driveway, sidewalk, or patio is to apply a sealer that will keep them out.
