How to apply color hardener?
Color Hardener Application Tips 1 Monitor your weather conditions on the job for future reference regarding how they affected your pour. Keep notes. 2 Pre-fluff your color hardener before the pour and split the volume of material into multiple pails for ease of application. 3 Pour at a slump that’s workable but does not promote bleed water. 4 Remove float lines and edger marks. They will show through in your finished work. 5 Apply your first and second application of hardener as soon as possible. This ensurse you have adequate moisture available in the concrete to activate the color hardener. 6 Do not apply water to activate the hardener. All moisture to activate the hardener should be from the concrete itself. 7 Evaporation reducers or retarders are OK to use, but they should be restricted to proper usage. Use after screeding and before the first floating. Do not cheat and use the evaporation retarder to activate your color hardener on the surface of the concrete. 8 Pour a piece of manageable size for your crew to do comfortably. Remember quality, not quantity, is your main goal and objective. 9 Avoid covering a fresh pour with plastic. This may cause discoloration.
