It is ideal to sweep the concrete of any debris and then go over it with a pressure washer. It would also be a good idea to mix some soap and water with your pressure wash mix. Once the concrete has been cleaned your next step is to lay down the layer of mortar. The mortar is what holds the tiles in place.
As a result, you want to make sure to add a generous amount to help fill in any gaps. Additionally, you want to have the tiles ready to place before you lay the mortar down. This will ensure that it will not dry before you are done. Once the mortar has been laid down evenly, you are ready to start putting the tiles in place.
How long does concrete need to cure before tile can be installed? We understand from the PCA Portland Cement Association and the ACI American Concrete Institute that many variables affect the length of time a slab needs to cure and the length of time during which curling can be expected.
Some of the more common variables are:. You can see that it is not possible to definitively state how long the concrete should cure before tiling.
Although it may not be possible to say for sure, what is a typical period for the concrete to cure? This should remove any old paint on the floor, as well. Sweep the floor again and then clean the floor with a power washer, or several applications of mopping with bleach diluted with water. Allow to dry thoroughly.
For small, narrow cracks that do not show signs of moisture, use concrete filler -- which can be purchased in a tube in vinyl, epoxy or latex -- to fill the crack. Wearing rubber gloves to protect your skin, run a finger over the filler to make it flush against the concrete floor. If any moisture appears in the crack, use a hydraulic cement product instead.
Remove any loose concrete pieces from larger cracks before filling with concrete filler, also in a tube. If the crack is large enough, a small amount of concrete can be mixed up in a bucket and applied with a trowel. In all of the above scenarios, allow the filler to thoroughly dry.
