I need some advice on prepping my concrete to install Toughlock LVP 4.5 thickness SPC core. It’s a click lock waterproof floating floor from Flooring Liquidators. It comes with a attached foam pad. I pulled up carpet, padding, and carpet tack strip. I filled the holes from the tack strip with Sika Pro ready mix concrete patch. I took out the entry way tile and used a demo tool to scrape off the thinset. This took some of the concrete with it. So here is where I’m stuck! What product do I use to fill the holes it left as well as the crack? I bought Mapei planipatch patch. I am just not sure if this is the right thing to use. I was just going to cover the entry way with the planipatch where there is still a residue left of the thinset but I don’t want to create a bigger mess.
