I just bought a house and im tryin to turn the garage into an apartment and the floor has these like little crater things all over the place..I need to know what to use to fill it in so i can put some kind of flooring down.. they told me it was some kind of sealent stuff..
Most flooring outlets especially ceramic outlets can obtain a floor leveller, it is a quick-drying cement that is used usually used to smooth out dips, slopes and other irregularities in floors before another surface is put on top of it. It can be built up to 1/4. For more money there is a liquid-pour leveller that you pour onto the floor and spread it out over the floor with a large garage squeegee or wiper.
