Safer to use - The endothermic melting action does not release heat that is common to many ice melters. Some competitive products can generate heat in small areas to 140F, making them unsafe around children and pets.
Easier to use - The color coverage indicator makes the product easier to see on snow and ice during application.
Does not irritate skin - Safer for children and pets.

Does not damage vegetation - when used according to label instructions.

Does not damage leather footwear.

Non tracking - carpets and floors stay clean longer.

Does not - chemically attack good quality concrete.

Reduces corrosive effects of ice melters - on metal surfaces...contains anti corrosion agents and CMA.

Storage life - is longer than competitive products.

And now with an added bonus - Activar® ultimate accelerator which makes MAC® w/CMA melt ice faster.

Product Information

Winter is hard on everything, that's why you need an ice melter that melts below zero while being gentle on everything else. Snow and ice are this product's only real enemies. After application, its special chemistry goes to work by quickly lowering the melting temperature of ice, even as temperatures drop to -5F. While the melting action is taking place, the granular composition provides a surface traction.

 Independent laboratory testing shows the components of  MAC® w/CMA do not chemically attack good quality concrete that has been designed for exposure to winter weather and ice melter usage. However, the natural cycle of freezing and thawing of concrete by winter conditions can cause scaling damage to concrete. The use of any ice melting agent can increase these natural freeze/thaw cycles. Particularly vulnerable are those concrete surfaces in which sub-standard practices were used in the formulation, placement, finishing and/or curing stages of construction. Also vulnerable are all concretes that are less than one year old, precast steps, masonry (stone or brick), existing concrete that has exposed aggregate, is precast, prestressed, chipped, cracked, spalled, or weathered. The use of any ice melter on these types of surfaces is not recommended, and therefore can only be done at the user's own risk.

To minimize potential damage use MAC® w/CMA, and any other ice melting product, on only "quality concrete that is air entrained, mixed, place and cured according to recommendations of American Concrete Institute Committee 201. The potential for damage to concrete surfaces can also be decreased by sealing surfaces and by removing slush that results from melting.

Ice melting agents applied at much greater rates than recommended may interfere with traction or footing. When using any deicer, good housekeeping practices and use of outside mats and inside "walk-off" mats are encouraged for optimum safety and minimal impact on floor coverings.

When grass and shrubbery are adjacent to icy surfaces, particular care should be used to avoid excessive or repeated application, as it could cause damage. The use of this ice melting compound must be at the consumer's risk.

Warnings: Causes eye irritation - May cause skin irritation - May be harmful if swallowed

Avoid contact with skin or clothing. Do not take internally. Wash thoroughly after handling.

First Aid:  Eyes- In case of eye contact, immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses if worn. Get medical attention.

Skin- In case of skin contact, flush skin with plenty of water. Get medical attention if irritation persists. Remove contaminated clothing. Wash clothing before reuse.

Swallowed- If large quantities are swallowed, get medical attention. Do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person.
