One of the biggest mistakes that new tile installers make is not taking the time to ensure the correct preparation of the surface before starting their project. For those tile installers without a lot of experience, skipping the use of underlayment is one of those mistakes. Making the wrong choice of underlayment is another common issue.
The use of a tile underlayment is to create a solid and durable surface that helps with crack prevention and sometimes waterproofing. This can be done using a range of materials, which can be determined based on the condition of the subfloor as well as the actual specifics of the job. For example, in moisture rich areas such as bathrooms or kitchen areas, having an underlayment that is water resistant is a must.
Common Materials
The most common types of underlayment used in general tile applications include different types of backer boards with waterproof coatings, plastic roll out membranes, and thin waterproof fabrics.
A more advanced option in tile underlayment that can provide a range of different features is the different types of membranes that are now available on the market. Most of these underlayments come in rolls but can also come by the sheet depending on manufactures size selection. One of the most common membrane types used is designed with a waffle like structure. This allows thin-set to be anchored into each square and allows for transitions or small blemishes in the subfloor to be tiled over giving you little to no trouble when doing so. As with most other types of membranes, it also provides a barrier for moisture penetration through to the subfloor.
