When doing a tight joint with a polished natural stone or a tight joint
with a polished or unpolished porcelain tile it is very important that
your substrate be very flat so the finished tile work will look great.
To get a nice finished tile floor you need to start from the beginning and make sure the substrate it flat, smooth and strong. This will ensure that when your tile contractor is setting the tile you don’t have rolls, lips or uneven tile.
The prep work can make or break a tile project.
Doing a lot of home tile renovations and new homes in Florida in the Tampa, Lakeland, Sarasota, Orlando & the Daytona areas I have seen my fair share of horrible wavy slabs with humps, dips and incorrect rough textures.
There are many ways of correcting this……
If the slab or floor area cannot be properly made flat.
You could also “wetset” mud the tile or natural stone when you set it.
With the proper Tile Contractor all of these methods
can help you achieve a smooth finished tiled floor.
