SPECTRUM ECO-PREP is non-corrosive, low odour, VOC-compliant, and contains no hazardous inorganic acids.<\/p>\n<p><strong>USES<\/strong><\/p>\n<p>SPECTRUM ECO-PREP is specifically formulated to prepare concrete or masonry surfaces by providing a moderate surface texture\/profile.\u00a0 SPECTRUM ECO-PREP was initially formulated to be used prior to applying <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/spectrum-water-based-stain\/\">SPECTRUM WATER-BASED STAIN<\/a> from W. R. MEADOWS, but it can be used anywhere a moderately textured\/profiled concrete\/masonry surface is desired.<\/p>\n<p>NOTE:\u00a0 SPECTRUM ECO-PREP is not designed to remove any material(s) that would inhibit the proper adhesion\/bond of SPECTRUM WATER-BASED STAIN (or alternative product) to the concrete\/masonry surface. This includes, but is not limited to:\u00a0 grease; glues\/mastics; paints\/coatings; concrete curing compounds; adhesives; form release; and penetrating products such as silicates, silanes, siloxanes, etc. Use an appropriate, commercially available chemical and\/or mechanical concrete\/masonry stripper as needed to completely remove previous products, treatments, coatings, etc.<\/p>\n<p><strong>FEATURES\/BENEFITS<\/strong><\/p>\n<ul>\n<li>Water-based formulation.<\/li>\n<li>User-friendly alternative to hazardous, organic acid-based etching compounds.<\/li>\n<li>Easy cleanup, no acid disposal.<\/li>\n<li>Low odour.<\/li>\n<li>Non-flammable, non-combustible<\/li>\n<li>Non-corrosive<\/li>\n<li>VOC compliant.<\/li>\n<\/ul>\n<p><strong>PACKAGING <\/strong><\/p>\n<p>7.58 L (2 U.S. Gallon) Containers, 18.93 L (5 U.S. Gallon) Pails<\/p>\n<p><strong>COVERAGE<\/strong><\/p>\n<p>Approximately 6.1 m\u00b2\/L (250 ft.\u00b2\/gal.).<\/p>\n<p>Coverage will vary due to porosity, profile, application technique, and condition of the concrete\/masonry substrate, etc.<\/p>\n<p><strong>SHELF LIFE<\/strong><\/p>\n<p>When stored indoors in original, unopened containers at temperatures between 4\u00b0 &#8211; 32\u00b0 C, optimum performance and best use is obtained within one year of date of manufacture.<\/p>\n<p><strong>TECHNICAL DATA<\/strong><\/p>\n<table class=\"table\" width=\"100%\">\n<tbody>\n<tr>\n<td>Appearance:<\/td>\n<td>Green Liquid<\/td>\n<\/tr>\n<tr>\n<td>Solids, Wt. %:<\/td>\n<td>40 +\/- 1<\/td>\n<\/tr>\n<tr>\n<td>Weight per 3.79 litres (1 U.S. gal.):<\/td>\n<td>4.5 kg (9.9 lbs.)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>SPECIFICATIONS<\/strong><\/p>\n<ul>\n<li>Complies with VOC Concentration Limits for Architectural Coatings Regulations in Canada<\/li>\n<\/ul>\n<p><strong>APPLICATION<\/strong><\/p>\n<p><strong>Interior Applications \u2026 <\/strong>The following instructions are to be used to prepare the concrete\/masonry surface to receive SPECTRUM WATER-BASED STAIN.\u00a0 If a product other than the SPECTRUM WATER-BASED STAIN will be applied, please consult the product manufacturer for recommended surface preparation, application instructions, etc.<\/p>\n<ol>\n<li>Thoroughly protect all adjacent areas, including, but not limited to: exposed metal, door knobs, walking strips, etc. &#8211; anything that is not going to receive SPECTRUM ECO-PREP.<\/li>\n<li>Using an appropriate, commercially available chemical and\/or mechanical concrete\/masonry stripper, thoroughly remove any paint, coating, concrete curing compound, adhesive, etc. from the concrete PRIOR to applying SPECTRUM ECO-PREP.
