Non-Toxic Acrylic Concrete Sealer for Decorative or Colored Concrete
January 9, 2013
Acrylic concrete sealers give colored and decorative concrete the "wet look" that deepens the color. They are the easiest to use, most common and least expensive products. They also protect the colored surface from wear and tear. Water cannot penetrate into it and oil and grease won't stain the concrete either. For years contractors and homeowners have used solvent-based sealers. Now the option of using a non-toxic and environmentally friendly water-based concrete sealer is an option.
Tougher Environmental Regulations
In the past only solvent-based concrete sealers were used to give the glossy wet look. These were high in solvents and Volatile Organic Compounds (VOCs) that caused air pollution. Tougher regulations have nearly eliminated the traditional sealers from the market. States such as California and areas such as the Northeast and Southeast have made high VOC concrete sealers unusable.
Low VOC Solvent-Based Concrete Sealers
Manufacturers have developed low VOC sealers that are solvent based. However, most are toxic and flammable. Special care must be used in the handling, shipping and application of these products.
Non-Toxic Water-based Acrylic Sealer
Water-based acrylic concrete sealers are non-toxic, non-flammable and 50 State legal. They have very low VOC content so that they do not harm the air or environment. And they give a medium wet look to the substrate. Water-based sealers are easy to apply by low pressure sprayers, rollers or brushes. They can be used on patios, driveways, sidewalks and any other area that needs a protective film to stop water, stains, oil and grease.
Water-based sealers can also be used indoors, especially where a low odor application is desired. Foyers, wash rooms, laundries or other areas inside that need a protective coating are excellent uses for a water-based acrylic sealer. And they are approved by the USDA for incidental contact when cured.
Protects Concrete from Freeze-Thaw Cycles
Water that gets into concrete can cause spalling if it freezes. Sealing it reduces spalling, premature cracking and hairline crack checking. De-icing salts are kept out so that the metal reinforcement does not get corroded by the salty melt water. This also increases the life of the concrete.
Safe and Non-Toxic Acrylic Sealer
For your colored concrete project, think of using a water-based acrylic concrete sealer. These are safer for the environment and the user. End the end the finished product is a protective film that stops grease and oil stains, seals out water and protects the coloring used in the concrete.
