Before application, thoroughly cure floors to receive treatment for minimum28 days, keep clean, unpainted, free from membrane curing compounds, andperfectly dry with all Work above them completed.B. Apply hardener evenly to surface, using three coats, allowing 24 hoursbetween coats.1. First coat 1/3 strength, second coat 1/2 strength, and third coat2/3 strength, mix with water.2.

Vapor Transmission Test: Conduct test on new and existing concrete to showthat no surface moisture exists prior to application of specified special floortreatment, as follows:1. Place polyethylene plastic sheet, minimum 4 feet by 4 feet and sealedalong four sides with duct tape to prevent moisture transmission byevaporation, over concrete floor area for 24 hours.2. Indication of moisture transmission will be apparent by accumulation ofmoisture on enclosed surface of polyethylene plastic sheet.3. Do not apply concrete bonding agent until test results indicate moistureis not being transmitted from concrete surface.B. Strength Tests: Test metallic aggregate topping for compressive strength bymaking 2-inch by 2-inch cubes in accordance with ASTM C109.PW/WBG/382059CONCRETE FINISHINGAUGUST 15, 2012 03 35 00 - 3©COPYRIGHT 2012 CH2M HILL
