This waterborne solution, when properly applied, offers substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the concrete surface when compared to untreated concrete. As LIQUI-HARD is applied and penetrates into the concrete surface, a chemical reaction takes place, producing a by-product that fills the pores of the concrete. This process produces a substantially denser concrete surface with enhanced durability. In addition to the densifying and hardening action, LIQUI-HARD also solidifies the concrete, eliminating dusting and pitting.<\/p>\n<p><strong>USES<\/strong><\/p>\n<p>LIQUI-HARD is recommended for use wherever hardened, dustproofed, and improved chemical- and abrasion-resistant surfaces are required. Ideal applications include floors in industrial plants and warehouses, storage silos, sewage plants, chemical processing facilities, refineries, and heavy pedestrian floor traffic areas, such as civic centers, sports arenas, stadiums, hospitals, airports, and museums. LIQUI-HARD can successfully be used in conjunction with shake-on hardeners.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/can.wrmeadows.com\/images\/induroshine2.jpg\" alt=\"Induroshine\" \/><\/p>\n<p>The <a href=\"https:\/\/can.wrmeadows.com\/concrete-densifiers-hardeners-polished-concrete-flooring\/\"><strong>INDUROSHINE<sub>\u00ae<\/sub><\/strong> system<\/a> from W.

Keep the surface wet with LIQUI-HARD for a minimum of 30 minutes. (A range of 30-60 minutes may be required depending on temperature and conditions.) NOTE: Pay particular attention to porous and\/or dry areas. These areas must be kept wet at all times with LIQUI-HARD. Once the surface begins to gel and become slippery, immediately spray the surface with a light water mist. Scrub the surface with a broom or mechanical scrubber to increase the penetration of LIQUI-HARD. Continue to work LIQUI-HARD into the surface for another 5 &#8211; 10 minutes or until LIQUI-HARD becomes gelled and slippery for a second time. At this time, THOROUGHLY flush the surface with water. During the flush process, agitate the surface with a broom to aid in removal of the excess LIQUI-HARD. Remove all excess material with a mop or squeegee. Thoroughly squeegee the surface dry. If there are slippery patches, this is an indication that there is still excess LIQUI-HARD present. These areas should be re-flushed and squeegeed again until the entire surface is dry. (Extremely porous surfaces may require a second application.)<\/p>\n<p><strong>WARNING:<\/strong>\u00a0 Failure to thoroughly wash and remove all excess material from floor surfaces may result in unsightly white stains.\u00a0 Immediately wash off over-spray from glass, aluminum, or highly polished surfaces with water to avoid etching of surfaces. For application assistance, contact W. R. MEADOWS at (800) 342-5976.<\/p>\n<p><strong>Burnishing<\/strong> \u2026 LIQUI-HARD can be burnished to a high sheen on steel trowel concrete floors.\u00a0 A high-speed burnisher (2000 &#8211; 2200 rpm) with appropriate maintenance pad is needed.<\/p>\n<p><strong>Drying Time<\/strong> \u2026 2 to 4 hours.\u00a0 LIQUI-HARD dries very quickly on new, virgin concrete.\u00a0 Drying times may be extended on existing (old) concrete due to surface conditions.\u00a0 Restrict foot traffic for at least four hours, 12 hours is preferable.<\/p>\n<p><strong>Clean Up<\/strong> \u2026 While still wet, equipment may be cleaned quickly and easily with soap and water.\u00a0 Do not allow LIQUI-HARD to dry before flushing excess from surfaces.<\/p>\n<p><strong>PRECAUTIONS<\/strong><\/p>\n<p>DO NOT DILUTE.\u00a0 Do not apply if the temperature of the concrete is less than 2\u00ba C or above 57\u00ba C.\u00a0 <strong>KEEP FROM FREEZING<\/strong>.\u00a0 If frozen, product should be thawed and agitated slightly prior to use.<\/p>\n<p><strong>HEALTH AND SAFETY<\/strong><\/p>\n<p>LIQUI-HARD is non-combustible. \u00a0(Flash point is greater than 98.8\u00ba C.\u00a0 Direct contact will result in irritation of the skin and eyes.\u00a0 Inhalation of product mist may result in respiratory irritation.\u00a0 Refer to <a href=\"https:\/\/can.wrmeadows.com\/Msds-2K-CAN\/3325-000.pdf\">Safety Data Sheet<\/a> for complete health and safety information.<\/p>\n<p><strong>MASTERFORMAT NUMBER AND TITLE<\/strong><\/p>\n<p>03 35 00 \u2013 Concrete Finishing<\/p>\n<p><a href=\"https:\/\/can.wrmeadows.com\/green-line-products\/\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/can.wrmeadows.com\/pics\/greenline-sm.jpg\" alt=\"GREEN LINE Products\" width=\"216\" height=\"100\" border=\"0\" \/><\/a><\/p>\n<p>2023-03<\/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>LIQUI-HARD concrete densifier and chemical hardener compound is a proprietary, ready-to-use, clear silicate liquid, formulated with chemically reactive materials to harden and dustproof concrete.

This waterborne solution, when properly applied, offers substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the concrete surface when compared to untreated concrete. As LIQUI-HARD is applied and penetrates into the concrete surface, a chemical reaction takes place, producing a by-product that fills the pores of the concrete. This process produces a substantially denser concrete surface with enhanced durability. In addition to the densifying and hardening action, LIQUI-HARD also solidifies the concrete, eliminating dusting and pitting.","breadcrumb":{"@id":"https:\/\/can.wrmeadows.com\/en-ca\/liqui-hard-canada\/#breadcrumb"},"inLanguage":"en-CA","potentialAction":[{"@type":"ReadAction","target":["https:\/\/can.wrmeadows.com\/en-ca\/liqui-hard-canada\/"]}]},{"@type":"ImageObject","inLanguage":"en-CA","@id":"https:\/\/can.wrmeadows.com\/en-ca\/liqui-hard-canada\/#primaryimage","url":"https:\/\/can.wrmeadows.com\/wp-content\/uploads\/liqui-hard-concrete-densifier-chemical-hardener-2.jpg","contentUrl":"https:\/\/can.wrmeadows.com\/wp-content\/uploads\/liqui-hard-concrete-densifier-chemical-hardener-2.jpg","width":320,"height":240,"caption":"Concrete Densifier & Chemical Hardener - LIQUI-HARD"},{"@type":"BreadcrumbList","@id":"https:\/\/can.wrmeadows.com\/en-ca\/liqui-hard-canada\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/can.wrmeadows.com\/en-ca\/"},{"@type":"ListItem","position":2,"name":"Construction Products","item":"https:\/\/can.wrmeadows.com\/en-ca\/c\/construction-products-en-ca\/"},{"@type":"ListItem","position":3,"name":"Construction Liquids","item":"https:\/\/can.wrmeadows.com\/en-ca\/c\/construction-products-en-ca\/construction-liquids-en-ca\/"},{"@type":"ListItem","position":4,"name":"Concrete Densifiers &amp; Hardeners","item":"https:\/\/can.wrmeadows.com\/en-ca\/c\/construction-products-en-ca\/construction-liquids-en-ca\/concrete-densifiers-hardeners-en-ca\/"},{"@type":"ListItem","position":5,"name":"LIQUI-HARD (Canada)"}]},{"@type":"WebSite","@id":"https:\/\/can.wrmeadows.com\/en-ca\/#website","url":"https:\/\/can.wrmeadows.com\/en-ca\/","name":"W.
