What is the Best Backer Board To Use in a Shower
After ripping out the original 3 inches of concrete, tile, and metal lathe in my old school shower, it was time to replace it with concrete backer board or underlayment substrate. There are several options of backer board some better than others. It is important to find board that is strong enough and water resistant enough to support your new tile.
Things I learned about cement board.
#1 – It is great for tile adhesion
#2 – It is extremely tough and long-lasting
#3 – It is very rigid
#4 – It repels water and is naturally mold resistant
#5 – It can also be used in outdoor applications, in case you wanted to make your shower outdoors
#6 – It is simple to score and cut
#7 – Usually comes in 3 x 5 foot panels
Cement board is used as a tile backer for residential and commercial space including bathroom, and showers and perfect for wet
areas particularly your shower.
Cement board is not meant to be painted on just tiled.
Cement boards are now lighter and easier to manage. Cement boards today are typically 25% lighter than previous cement boards. It is also
simple to score and cut as well as fasten to the wall.
Here are some quick tips to choosing the right concrete backer board.
Tip #1: Make sure you have thick enough backer board. At least 1/2 inch board is necessary in a shower.
Tip #2: Choose a brand name like Hardie Board or USG
Tip #3: Allow for extra board. You always need more than you think particularly around doors, windows, and shampoo niches.
Personally I went with USG DuraRock NextGen based on the price and quality. Here’s a good video on USG Cement Board products.
