4) Groove cut to locate the profile
Next, we will cut the groove in the floor with a radial saw, which will be used to locate the lower guide. It is very important that the dimensions of the groove are the same as those of the floor guide, so, to make sure, we will make a 14 mm wide and 18 mm deep groove. In addition, we will have to take into consideration the floor’s material so as to use the right saw blade. If the floor is made of stone or marble, we will use a pneumatic hammer, or we will carry out carpentry work to polish and even out the space resulting from the groove.
