Common areas of application include patios, pool decks, driveways\/walkways, plazas, etc.\u00a0 SPECTRUM 930 Patina Acid Stain cannot be used to hide surface imperfections or to cover construction errors.\u00a0 The final colour obtained is unique to each concrete surface and is dependent on the chemical composition, mix design, porosity, age, texture, and colour of the original concrete substrate.<\/p>\n<p><strong>FEATURES\/BENEFITS<\/strong><\/p>\n<ul>\n<li>Permanently stains concrete surfaces.<\/li>\n<li>Will not disrupt the appearance of the natural concrete substrate.<\/li>\n<li>Easy application and clean up.<\/li>\n<li>Available in six different colours<\/li>\n<li>Colours may be blended onsite for custom projects<\/li>\n<li>Provides the artist or contractor with a myriad of decorative options.<\/li>\n<\/ul>\n<p><strong>PACKAGING<\/strong><br \/>\n1 Litre Units<br \/>\n4 Litre Units<br \/>\nCoffee colour only available in 4 L units.<\/p>\n<p><strong>COVERAGE<\/strong><br \/>\nAverage coverage is 9.82 m\u00b2\/L (400 ft.\u00b2\/U.S. gal.) per coat. Coverage will vary widely depending on the porosity and texture of the surface, as well as preparation and application techniques.\u00a0 Material can be diluted up to 8:1.\u00a0 Note:\u00a0 Diluting the material will cause variation in the final colour.<\/p>\n<p><strong>SHELF LIFE<\/strong><br \/>\nWhen 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. Do not store at direct sunlight.<\/p>\n<p><strong>SPECIFICATIONS<\/strong><\/p>\n<ul>\n<li>Complies with Canada VOC Concentration Limits for Architectural Coatings Regulations.<\/li>\n<\/ul>\n<p><strong>TECHNICAL DATA<\/strong><br \/>\nCOLOUR:\u00a0 Available in Buckskin, Cinnamon, Coffee, Maligne Blue, Moss, and Pike Green.<\/p>\n<p><strong>APPLICATION<\/strong><br \/>\n<strong>Surface Preparation<\/strong><br \/>\n<strong>Newly Placed Concrete \u2026 <\/strong>Newly placed concrete should be cured a minimum of 14 days, but 28 days is preferred.\u00a0 Liquid curing materials must not be used.\u00a0 Immediately prior to staining, concrete must be thoroughly cleaned.\u00a0 Surface should be swept then pressure-washed.\u00a0 Use of a high-quality commercial detergent will facilitate cleaning.\u00a0 Surface must be rinsed after cleaning until the rinse water is completely clean.\u00a0 NOTE:\u00a0 Do not clean concrete by acid etching.<\/p>\n<p><strong>Existing (Old) Concrete \u2026 <\/strong>Existing concrete must be cleaned immediately prior to staining so that surface is completely penetrable.\u00a0 Test surface by applying drops of water.\u00a0 Water should immediately darken the concrete and be readily absorbed.\u00a0 If the water beads and does not penetrate, additional surface preparation is needed.\u00a0 To remove dirt and contaminants, detergents and other commercial cleaners may be used.\u00a0 Pressure washing or scrubbing with a rotary floor machine is sometimes required. NOTE:\u00a0 Do not clean concrete by acid-etching.<\/p>\n<p>After cleaning, surface must be rinsed thoroughly until the rinse water is completely clean.\u00a0 Wet vacuums may be used to remove dirty water.\u00a0 After drying, surface must be retested using the &#8220;water-drop test&#8221; to ensure adequate surface penetration.\u00a0 Additional spot-cleaning and rinsing may be required.<\/p>\n<p>Concrete that has been previously coated with liquid curing materials, paints, coatings, sealers, waxes, or water repellants, or surfaces that cannot be successfully cleaned by other methods, must be sandblasted.\u00a0 Sand remaining on surface should be removed by sweeping or pressure-washing prior to staining.<\/p>\n<p><strong>Application Method \u2026 <\/strong>All application and surface preparation procedures and equipment should be tested for suitability and acid-resistance before use.\u00a0 Metal containers should never be used to hold SPECTRUM 930 Patina Acid Stain, as they will rapidly corrode and possibly change the colour of the stain.\u00a0 Suitable protective gear should be worn and government regulations and all applicable safety requirements should be followed.<\/p>\n<p>Mask off any areas that should not come into contact with SPECTRUM 930 Patina Acid Stain using <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/red-rosin-paper-canada\/\">RED ROSIN PAPER<\/a> from W. R. MEADOWS.\u00a0 Apply stain with an acid-resistant hand-pump sprayer, sponge, lambs-wool applicator, mop, roller, or brush following the recommended coverage rates.\u00a0 A fizzing action will result when stain comes into contact with concrete surface.<\/p>\n<p>NOTE:\u00a0 If there is no evidence of fizzing, the concrete is not sufficiently prepared to receive the stain or additional cleaning may be necessary.<\/p>\n<p>SPECTRUM 930 Patina Acid Stain should be transferred to the surface by brush or spray and immediately scrubbed in as soon as it touches the concrete, using a circular or figure-eight motion.\u00a0 Work in small sections, keeping the brush in constant contact with the surface and in continuous motion until the fizzing stops.\u00a0 To avoid lap marks, reacted solution should not be spread to new work sections, but should only be overlapped with and worked into the edges of the adjacent, still wet, previously stained areas.\u00a0 A wet-edge must be maintained.<\/p>\n<p>SPECTRUM 930 Patina Acid Stain should be allowed to remain in contact with the concrete until the desired effect is obtained, which is typically a minimum of four hours.\u00a0 For both single- and mixed-colour applications, the stained surface should be washed between applications to fully evaluate the colour effect before an additional coat is applied.\u00a0 NOTE:\u00a0 The longer SPECTRUM 930 Patina Acid Stain is left on the concrete, the more intense the colour will be.<\/p>\n<p>Pre-wetting the surface may reduce the occurrence of lap marks, but also will decrease the colour intensity of the stain.<\/p>\n<p><strong>Rinsing\/Neutralization \u2026 <\/strong>After the final application of SPECTRUM 930 Patina Acid Stain has remained on the surface a minimum of four hours, all unreacted SPECTRUM 930 Patina Acid Stain must be neutralized using a solution of baking soda (sodium bicarbonate) and water, using 0.45 kg (1 lb.) of baking soda per 18.9 L of water. This solution should be applied until fizzing has ended.\u00a0 Surface should then be rinsed several times with clean water to remove all residue.\u00a0 All runoff should be collected by wet-vacuuming or absorbing with an inert material.\u00a0 After rinsing, a wet strip of pH paper should be placed on the concrete.\u00a0 If the pH reads 7 or higher (when compared to colour chart), the concrete has been properly neutralized.\u00a0 If the pH is below 7, further neutralization is needed.\u00a0 After completion of neutralization, rinsing, and a pH check, the stained surface should be tested for cleanliness by wiping with a white cloth or glove.\u00a0 If residue appears on the cloth or glove, additional surface cleaning is necessary.<\/p>\n<p><strong>Failure to completely remove all residue prior to sealing the concrete will cause appearance defects, adhesion loss, peeling, reduced durability, and possible bond failure and delamination of the sealer.<\/strong><br \/>\n<strong>\u00a0<\/strong><br \/>\n<strong>Sealing \u2026 <\/strong>Protect SPECTRUM 930 Patina Acid Stain applications with <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/decra-seal-voc-decorative-concrete-cure-seal\/\">DECRA-SEAL<sub>\u2122<\/sub> (VOC)<\/a> or <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/decra-seal-wb-canada\/\">DECRA-SEAL W\/B<\/a> from W.

MEADOWS.\u00a0 NOTE:\u00a0 Wetting the concrete surface will give an indication of how the substrate will look once a sealer is applied.\u00a0 Allow the concrete to dry thoroughly prior to sealer application.<\/p>\n<p><strong>Drying Time \u2026<\/strong> SPECTRUM 930 Patina Acid Stain drying times will vary with temperature and relative humidity.<\/p>\n<p><strong>Cleanup \u2026 <\/strong>Suitable protective gear should be worn.\u00a0 SPECTRUM 930 Patina Acid Stain cleans up with water.\u00a0 All federal, state, and local regulations should be followed for proper disposal.<\/p>\n<p><strong>PRECAUTIONS<\/strong><br \/>\nThe colour obtained and depth of penetration is not predictable.\u00a0 For this reason, prior to general application, a representative jobsite test section must be produced and approved on each individual concrete surface for each colour to verify and approve suitability.\u00a0 There are instances where it is not possible to successfully stain certain concrete surfaces.\u00a0 Concrete from different loads or pours and in patched areas may appear significantly different in colour from adjacent areas when chemically stained.\u00a0 Please <a href=\"https:\/\/can.wrmeadows.com\/tech-form\/\">contact a technical representative<\/a> from W. R. MEADOWS for a colour selector.\u00a0 All equipment and containers should be tested for acid resistance prior to use.\u00a0 Metal containers should never be used as they will rapidly corrode and change the colour of the stain.\u00a0 Avoid direct contact with this product as well as inhalation of vapors. Separation can occur, but the product can easily be re-dispersed, without affecting its performance. \u00a0\u00a0DANGER!\u00a0 CORROSIVE MATERIAL.\u00a0 CAUSES SEVERE EYE IRRITATION, WITH POSSIBLE BLINDNESS.\u00a0 CAUSES EYE AND SKIN BURNS.\u00a0 MAY BE FATAL IF SWALLOWED, INHALED, OR ABSORBED THROUGH SKIN.\u00a0 Refer to Safety Data Sheet for complete health and safety information.<\/p>\n<p><strong>MASTERFORMAT NUMBER AND TITLE<\/strong><br \/>\n03 35 00 &#8211; Concrete Finishing<\/p>\n<p><a href=\"https:\/\/can.wrmeadows.com\/en-ca\/leed-guide\/\"><strong>LEED INFORMATION<\/strong><\/a><br \/>\nMay help contribute to LEED credits:<\/p>\n<ul>\n<li>MRc9: Construction and Demolition Waste Management<\/li>\n<li>EQc2: Low-Emitting Materials [For Healthcare and Schools (exterior-applied products) ONLY]<\/li>\n<\/ul>\n<p>2018-02<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/can.wrmeadows.com\/pics\/foot-can.jpg\" alt=\"\" width=\"640\" height=\"98\" align=\"BOTTOM\" border=\"0\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/can.wrmeadows.com\/pics\/footer-can.jpg\" alt=\"warranty\" width=\"614\" height=\"212\" align=\"BOTTOM\" border=\"0\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>SPECTRUM 930 Patina Acid Stain is a ready to use, penetrating product that reacts with concrete to produce a unique and permanent coloured surface.<\/p>\n","protected":false},"author":1,"featured_media":19372,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"content-type":"","_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"full-width-content","footnotes":""},"categories":[140],"tags":[],"class_list":{"0":"post-1399","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-concrete-finishing-en-ca","8":"entry"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.5 (Yoast SEO v27.5) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>SPECTRUM 930 (Canada) - Patina Acid Stain - W.
