How to Install Raised Floors Over Concrete Slab
Building a raised floor over concrete slab floors is in your best interest. A raised floor is a great finish to have over your concrete and it also allows for a little room between the foundation and the raised floors so as to limit damage from flooding. If you are new to this kind of project, here are a few tools and materials that you will need, along with some steps that can help to guide you:
Step 1 - Apply Adhesive
To install the floors, you will need to pick out the tiles and apply adhesive to the back. Before doing this though, lay the tiles out so that you can decide what should go where and if they fit. You can use a tile adhesive and apply it to the back of the tile. Many times you will need to cut the tiles to size because when you start in the center and work your way out, the ends will have to come up and meet the walls.
Step 2 - Lay Tiles
Lay the tiles one by one beginning with the center and working your way out. You want to make sure that they are even and lined up so that they flow throughout the flooring. Now you can do any actual cutting that may need to be done. Be sure that you use a tape measure, a straight edge and a utility knife. Once you have cut everything and you know the pattern that you want them to be laid in, you can begin to secure them to the floor. Peel back the adhesive backing and then apply any more adhesive that you may need still with a paintbrush evenly on the back of the tile or on the area of flooring that you will be attaching it to. Hold each tile down securely for a minute or so to allow it to set. Be sure that you press down evenly so one part of the tile isn't secured more than another side.
Step 3 - Grout
Now that the tiles are down and have been set, you can grout over them. Use a trowel to rub the grout over the tiles and get into the cracks. Even it out completely so that you get into every groove but also make sure that you spread it thinly across the tile so that you can wipe it off after you have made sure that the grout has gotten into the small spots. Then, with a damp sponge, be sure to get the excess grout off of the tile so that it doesn't dry on there.
Once you are finished you will want to allow the tiles to sit for a few hours so that they can dry and the grout can seep in and set. Refrain from walking on it for a day or so.
