When you leave your concrete warehouse floors unsealed, the concrete will produce flecks of concrete dust that can coat machinery, create a dirty work environment, wreck havoc on manufacturing, and even cause health issues. It's simply unavoidable and a very real issue unless you seal the floors.
Outdoor concrete sealers are not only worthwhile but necessary. Experts who recommend having a concrete surface sealed are doing their customers a big favor. Without this extra layer of protection, concrete will absorb moisture and may begin to crack, spall, flake, and discolor, among other things.
Concrete can be described as a hard sponge that soaks up oil and water-based spills. Easily marked by tires and outdoor elements, it is important to seal the surface, so it looks beautiful year-round. The other benefit to sealing concrete is improved cleaning and maintenance.
After you complete a concrete job, don't neglect the single most important step to ensure that it lasts a lifetime: sealing. With a high-quality sealant—and this helpful guide—you can waterproof and protect your new concrete surfaces for years to come.
If your concrete is new, you'll need to let it cure; wait at least one month before applying sealer. Before you apply it, check the weather. Sealer needs to be applied in dry conditions because it won't adhere to damp concrete.
When concrete is dry and not sealed, it can absorb some water the same way that water escaped in the drying process. Humid environments, rain, and standing water are obvious threats. Sealing helps, but cracks exist in most concrete, and over time water can work its way in.
After discussing the factors you need to look for and the regional location of the project, in broad terms, Spring is in fact the best time of year to seal concrete. With its moderate temperatures and humidity levels, it tends to provide ideal conditions for the application and curing of sealers.
It's Never Too Late …
Sealing your garage floor might not be possible if you have moisture in your garage. This is typically the only scenario where we don't recommend sealing right away, mainly because you should deal with the cause of the moisture first. It could be due to a plumbing leak or a drainage issue.
Sealing concrete is not a requirement, but most experts will recommend it depending on the placement and environment. Flat surfaces benefit the most from concrete sealant since it dries evenly and seeps into the small crevices.
If you have cracks in your concrete, sealing won't do anything for those. You'll expend money and effort on something that you might rather replace before too much longer. Sealers fade. The seal on your concrete will fade over time, especially in high-traffic areas.
To seal your concrete floor, pour a small amount of concrete sealer into a painting tray and apply the sealer evenly to your floors using a paint roller. Use a paintbrush to seal around the edges of the room. Always work from the furthest area of the room toward the exit so that you don't box yourself in!
Yes, you can build a slab on grade foundation in the fall and leave it till spring if it has been properly protected against frost heave, though it will most likely require additional insulation. I would suggest you consult with the engineer who designed it.
Sealing your concrete isn't really a labor-intensive, nor costly, job. By sealing your concrete every 2-5 years, as recommended by experts, you should keep your floor in good shape, preventing cracks, pitting, and additional damage.
As a general rule it takes 28-30 days for each inch of concrete to dry under the right environment. Higher temperatures and lower humidity conditions above the slab reduce the dry time.
The excess moisture that is still present after a new driveway installation needs to completely evaporate before you seal the concrete. This evaporation is known as the curing process. As a rule of thumb, it takes approximately 28 days for new concrete to seal.
Generally, 50 degrees F (10 C) is the accepted minimum temperature when applying most film-forming concrete sealers and coatings. That number pertains to the temperature of the sealer, as well as the temperature of the air and the surface being treated.
Acrylic Concrete Sealers: Acrylic sealers last 1-3 years before they need to be re-coated. Epoxy Coatings: Epoxy coatings last 5-10 years before they need to be re-coated. Urethane Coatings: Urethane coatings last 5-10 years before they need to be re-coated.
While mold only feeds on organic materials, it can grow on any surface, especially concrete. While concrete may not supply an abundance of organic material, it provides just enough mold to spread to other areas of a building.
Insufficient curing and sealing at the surface; if the concrete is not cured and sealed properly, moisture, oil and / or grease will slowly disintegrate the concrete therefore producing dust.
Unsealed concrete is a porous material that freely absorbs liquids and is therefore vulnerable to unsightly staining from oils, chemicals, animal waste, moulds and much more besides. As an absorbent material, it is also vulnerable to frost damage in the freeze/ thaw cycle and is readily eroded by de-icing salts.
If water evaporates too quickly, it will weaken the finished product with stresses and cracking. To put it simply, the goal is to keep the concrete saturated during the first 28 days. The first 7 days after installation you should spray the slab with water 5-10 times per day, or as often as possible.
