+ Is MELT safe on all surfaces?
MELT is safe for use on all surfaces, and will not harm grass, wood, concrete, metals, or other vegetation when used as directed. MELT should not be used on freshly poured concrete that has not had time to cure.
+ Are MELT Calcium Chloride Crystals safe for sidewalks and concrete surfaces?
MELT Calcium Chloride Crystals is recommended for deicing asphalt and concrete surfaces that have been designed and constructed for winter weather conditions and deicer usage. MELT Calcium Chloride Crystals will not chemically attack asphalt or concrete. Melted water from the deicing process may soak into porous concrete and re-freeze, creating pressure within the concrete structure. Concrete is resistant to scaling damage if it is air-entrained, mixed, placed and cured according to the recommendations of the American Concrete Institute Committee 201.
Please note, MELT Calcium Chloride Crystals are not recommended for deicing concrete that is less than one year old, precast steps, masonry (stone, brick, mortar joints), or existing concrete that has exposed aggregate, is precast, prestressed, chipped, cracked, spalled or weathered.
+ What temperature do MELT Calcium Chloride Crystals melt to?
Your MELT Calcium Chloride Crystals are effective to -25°F (-31°C).
+ What is the best way to use MELT Calcium Chloride Crystals?
For best results, plow or shovel snow accumulations prior to spreading MELT Calcium Chloride Crystals. Spread evenly, using a cup, scoop or spreader to apply. Since MELT Calcium Chloride Crystals are more effective than other ice melters, use only 1/4 to 1/2 cup (2 to 4 oz) per square yard. Remove melted ice/snow slush. Apply shortly after snow begins to assure easy removal of snow and prevent ice buildup. Removal of thick ice may require higher application rates to penetrate and undercut the ice layer.
+ What are the active ingredients in MELT Calcium Chloride Crystals?
MELT Calcium Chloride Crystals contain the strongest and most effective materials for melting ice and snow in the industry. The active ingredients are as follows:
- Sodium Chloride CAS No. 7647-14-5
- Calcium Chloride CAS No. 10043-52-4
+ Can MELT Calcium Chloride Crystals that have caked be made usable again?
When MELT Calcium Chloride Crystals are stored in a manner that allows contact with humid air, the product is likely to become caked. If lightly caked, the product may be broken up into usable form by knocking the closed package against a hard surface, similar to breaking up a bag of ice from a convenience store. In other cases, the caked product may be too hard for this approach to be effective. Use of forceful hammering is not likely to be effective and is not recommended, as flying chips of product could be a hazard, particularly to eyes. Caked product that cannot be broken up into usable form may be disposed of according to guidance on the product label.
+ Is calcium chloride safe for use near grassy areas and other vegetation?
Under typical applications conditions, MELT Calcium Chloride Crystals will not damage grass or vegetation adjacent to a surface being deiced. As with fertilizer and any other deicer, it is possible for grass to be damaged if the chloride-based deicer is over-applied or large quantities are directly applied to the grass or vegetation. Roadside damage to conifers caused by contact with chloride-containing mist from high-speed tire action is a potential issue with highway applications of any chloride-based deicer.
+ What is spalled concrete?
\"Spalled concrete\" is what happens to stamped concrete slabs as a result of snow and ice. It is the deterioration of the top layer of concrete, eventually seeping down throughout, causing flaking and scaling. While this may be the result of an improper finishing of the concrete, it can happen to any slab of concrete given enough fluctuation in extreme weather. Specifically, it is cause by water molecules infiltrating the surface of the concrete, and then freezing and thawing repeatedly; as water freezes and expands into ice, it breaks apart the concrete. Even \"harmless\" products like rock salt, calcium chloride, or urea may exacerbate surface spalling; these products cause rapid heating at first, but once consumed, there is the eventual refreezing that results in damage to concrete surfaces. This is because these products lower the freezing point of water, causing more frequent freeze-thaw cycling of the melted snow and ice, which causes surface spalling and scaling of concrete.
+ Can damage result from corrosion of rebar when MELT Calcium Chloride Crystals are used on concrete structures, such as bridges and parking garages?
The chloride ions in MELT Calcium Chloride Crystals can permeate porous concrete. When chloride, oxygen and moisture come together on the surface of unprotected steel reinforcement (rebar) embedded in concrete, corrosion will result. Rust formation on rebar places pressure on the concrete that can result in cracking, spalling and delamination. The loss of bond between concrete and reinforcing steel and the loss of rebar cross-sectional area both have the potential to result in serious structural problems.
Companies and trade organizations with expertise in concrete construction technology are familiar with options available for corrosion protection in new or rehabilitated structures. With support from these experts, each end user should determine whether or not application of chloride-based deicers is appropriate for their given situation.
+ Is it okay to use MELT Calcium Chloride Crystals for deicing wood surfaces?
The variety of wood treatments that could be used on exterior wood surfaces makes it difficult to predict the effect of calcium chloride deicers on those surfaces. Therefore, deicing wood surfaces with MELT Calcium Chloride Crystals is not recommended. MELT Calcium Chloride Crystals could potentially soak into untreated and some treated wood surfaces, resulting in damp spots that may be difficult to remove.
+ How can slipperiness be prevented when slush, snow melt and residual deicer are tracked onto hard surfaces of indoor flooring?
Always follow the directions on the product label for proper deicer use. Do not over-apply deicer, especially near entryways. Use effective entrance mats that absorb and trap snowmelt, slush or residual deicer. If residual deicer is tracked onto hard floors, it should be cleaned up with warm, fresh water as soon as possible. For example, soak a mop or towel in fresh water, wipe the surface and dry thoroughly. If a bucket is used for rinsing the mop or towel, the water in the bucket should be changed out frequently for best results.
+ What are the recommendations for cleaning carpets that have been tracked with dirt, grime and residual deicer?
Proper procedures for the clean-up of deicers that have been tracked onto carpets include a multi-step process that removes both the deicer and any dirt or oils that have also been tracked in and deposited on the carpet. The majority of experts recommend a cleaning procedure that includes a pH neutral detergent wash followed by hot water extraction.
+ Are MELT Calcium Chloride Crystals “pet-friendly”?
MELT Calcium Chloride Crystals present a low hazard to skin when used as directed, as brief contact is essentially nonirritating. If incidental ingestion occurs, it is not likely to cause injury because the toxicity of this product is low. If the product contacts the eyes, it should be washed out.
+ How should packages of MELT Calcium Chloride Crystals be stored?
MELT Calcium Chloride Crystals are both hygroscopic and deliquescent. This means that the product can absorb moisture from the air, even to the point of converting to liquid brine. For this reason, protecting solid calcium chloride from excessive moisture exposure is the primary requirement to maintain product quality while in storage.
MELT Calcium Chloride Crystals should be stored in a dry place. Avoid storing in areas where product leakage could cause damage. Some types of bags (i.e. valve closure bags) do not seal well if stored standing on end and should be stored lying flat. Opened packages should be tightly resealed after each use to prevent caking and liquid brine formation that may result from exposure to humid air.
Palletized product covered by an intact plastic shroud may be stored outdoors on a well-drained asphalt or concrete surface. If the shroud is torn, pierced or removed, the palletized product should be stored indoors or under a waterproof covering. Products packaged in drums or FIBCs (aka. Super Sacks or Big Bags) are typically not shrouded. Therefore, these packages should be stored indoors or under a waterproof covering.
MELT Calcium Chloride Crystals are temperature-stable under all ambient storage conditions.
