3 Ways to Cure Concrete

22/12/2019Non-cured concrete is susceptible to cracking and collapses so always cure new concrete There are 2 main methods of curing Wet-curing is covering the concrete with a sheet and keeping it soaked with water for 7 days It's time-consuming but produces the best results For a faster method spray the concrete with a curing compound to lock moisture in and aid the curing process Whichever
