I have a large entrance that was tiled and with time the tiles got damaged so I removed them. Now the stairs are bare, it's concrete. I would like to cover them eventually with standard mortar or patching. To avoid the infiltrations and that is anti-slip, what does exist like paintings or other applications?
On a floor with flatness defects of less than 1 cm choose a smoothing mortar, possibly fiber-reinforced, otherwise orient yourself towards the realization of a cement mortar screed. Remember to pass an adhesion primer before applying your mortar.
After total drying sand the surface, dust off and apply a water repellent surface to prevent seepage. Then, after total drying, you can pass a painting "special concrete floor" for intensive use. You can also apply a resin.
