    hello

    I live in a 50’s block. I’m clearing kitchen floor to self-level it, it’s a concrete floor that has previously been covered with assorted vinyl tiles.
    Removing them i found very loose layer of concrete which i have thought best to pull up before self-levelling. Its about 40mm thick slab, about a metre squared. I put down directly bluecircle multipurpose readymixed concrete, which i realise now i didnt put down a bonding agent before. However, my question mainly is, how long do i let the concrete dry or cure before sealing (with SBR?) and before putting down self-levelling compound. I really dnt want to mess this up but time is really of the essence. What’s the minimum time i can wait before sealing the new concrete and covering with leveller? Cheers people!
