1220-WHITE is a reflective curing compound designed for exterior use on freshly placed concrete surfaces, both horizontal and vertical, particularly where protection from the sun's heat is required. It is recommended for use on driveways, walls, sidewalks, concrete highways, runways, overpasses, bridges, tunnels, etc.
Resin-Based, Water Emulsion Concrete Curing Compound. 1250-WHITE is a dissipating, resin-based, white-pigmented concrete curing compound.
Efflorescence is the white powdery substance often seen on the surface of concrete or brick. Efflorescence is caused by water vapor migrating through the slab bringing soluble salts to the surface of the concrete. Many people mistake the white powdery substance with mold or mildew.
A: Concrete cure & seals are typically used on freshly-poured, newly-constructed concrete, as they are designed to help the concrete retain moisture and achieve optimal strength and durability, while also providing a protective seal.
Concrete sealant is a lot like car wax, which many people go without and regret when the paint is peeling off their car. Concrete sealer can make a difference in both the appearance and performance of concrete. After laying down concrete it is crucial to seal the concrete as soon as the concrete can be walked on.
Shotcrete, gunite (/ˈɡʌnaɪt/), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface. This construction technique was invented by Carl Akeley and first used in 1907.
If your concrete is exposed to cold climates at any point, it's important to start watering it as soon as possible in order to prevent shrinkage cracks. The slab should be treated with a fine mist each day until it has cured completely and reached around 80% of its final strength.
How Long Can Resurfaced Concrete Last? If applied in accordance with the manufacturer's specifications, a service life in excess of 15 years may be expected.
The answer depends on the surface's square footage. For large surfaces such as commercial floors, a sprayer is faster and way more efficient. Finally, for small surfaces, such as garages or any other exterior surface, a paint roller or any other type of roller will do the trick. Rolling is a less expensive process.
Ultimately, efflorescence itself isn't dangerous. However, it can lead to potential moisture problems that can cause structural damage to building materials. That means if you find efflorescence in the basement or on concrete and other structures, it's important to take action.
It's probably efflorescence. This crusty deposit is a buildup of salts brought to the surface when moisture evaporates from materials like brick or concrete. Although harmless at first, it may be a warning sign of underlying moisture issues.
X-FOAM expansion joint filler is a flexible, lightweight, non-staining, polypropylene, closed-cell expansion joint filler. It is a chemical-resistant, ultraviolet stable, non-absorbent, low density, cost-effective, compressible foam that offers an extended service life in both interior and exterior applications.
Trapped efflorescence can also build hydrostatic pressure if it cannot pass through the top coat. This leads to blistering that not only looks bad, but blisters can also damage the top coating of the sealer on your concrete driveway.
KLEEN KOTE creates a virtually non-stick coating on the surface of tools, machinery, vehicles and concrete form work when applied. KLEEN KOTE repels slurry, asphalt, concrete, paint buildup and overspray, dirt, mud, snow, ice and much more.
In short, the difference between cement vs concrete is easy to clear once we know all the basics of their compositions. Cement is a binding agent made from limestone and clay; whereas concrete is a building material created through the proper mixing of cement, water, sand, and rock.
It's highly durable and has a low permeability, meaning it can withstand life's strongest forces: weather, time and family. Best for outdoor areas, spray on concrete is perfect for refurbishing driveways and backyard spaces like patios and pool areas.
What's being sprayed on the concrete pavement is a curing compound. It goes on pink so crews can see where it has been applied, but it dries clear. This curing compound is sprayed on to prevent moisture from evaporating from the freshly placed concrete.
Moist curing is a common method of concrete curing. It involves wetting the concrete slab often with water (5-7 times per day) for the first 7 days. This method ensures your concrete slab will be extremely strong and durable, because it allows the moisture to evaporate slowly, preventing cracks and shrinks.
Concrete is usually dry enough after 24 to 48 hours to walk on. For concrete to dry and reach its full strength, it typically takes about 28 days per inch of slab thickness. Once conditions are conducive for the concrete to cure at 85-90% relative humidity.
Rain falling on freshly-poured concrete can cause damage to the surface, making it bumpy and uneven.
Concrete flooring is an extremely durable, hard-wearing type of flooring. When laid correctly by a concrete specialist, concrete flooring boasts an extremely long lifespan, with the same high performance and flawless aesthetic. However, standing water is one of the most common causes of damage to concrete flooring.
What you might be seeing is a curing compound that's sprayed on the concrete after placing and finishing. It's white to reflect the sunlight and keep the temperature of the concrete lower for a slower curing time. The concrete will eventually revert to a typical grey color over time.
Unlike concrete, when building gunite pools, you can stop and start without any problems, which will help give a smoother finish. With a skilled nozzleman, the mix of cement and water can be adjusted at the point of delivery as required, while it is also less prone to cracking than concrete.
