Backer Boards Comparison : I’m going to break down by category and cover the finer points of each type of Board behind Tile in Shower.
Board behind Tile in Shower – Sheetrock/Greenboard
Sheetrock in a wet area is a primary no-no. It generally works excellent for a kitchen backs plash or fire however as a shower tile backer board, it’s a horrific concept and in opposition to code. This additionally is going for moisture resistant drywall also called green board. It’s my expertise that inexperienced board isn’t authorized for residential moist areas anymore.
If sheetrock (drywall) receives wet it expands and swells and could break any tile which you’ve set up on it. There are better alternatives.
Glass Mat Gypsum Wall Board
The most popular product on this category is Densshield tile backer board [edit: apparently USG has entered this space also]. This product has taken the area of green board. it’s miles made of moisture resistant gypsum but it also has a water-resistant coating on its face. Like sheetrock, it’s smooth to install and really least expensive. because of these items, it’s far the new favorite of home builders anywhere. in which they used to use inexperienced board lower back inside the 1980’s they now use this new gypsum hybrid.
In tract homes and new production, it’s normally set up by the sheetrock group. generally, the sheetrock group (and generally the tile installers) don’t recognise how to properly water resistant the seams, screw holes, and edges. however it’s reasonably-priced and lasts lengthy sufficient which is song to most tract home builder’s ears.
Board behind Tile in Shower – Fiber cement board
Fiber cement board and cement board are carefully associated. You’ve in all likelihood heard of Hardiebacker tile backer board. Fiberock is another famous product in this class. It’s a kind of gray/beige coloured board and is to be had at any hardware box keep.
The tile backer forums that have already been mentioned are pretty smooth to reduce via scoring and snapping. however Hardiebacker and its competition aren’t nearly as smooth. It’s an awful lot stiffer and tougher. reducing it in 1/2 is plenty less complicated than slicing a 1-inch strip off the brink. you could use a talent saw or handheld grinder with a diamond blade to cut it but it’s will get dirt everywhere. including your lungs, if you don’t wear a masks. a few have observed that Hardiebacker shears paintings nicely and don’t create too much dirt however the drawback is that the brink isn’t constantly a smooth cut.
For installing make certain to apply the proper screws (or galvanized roofing nails) whilst putting in. I opt for screws due to the fact they don’t bang at the wall and reason cracking within the sheetrock in the relaxation of the room. The seams have to be taped with alkaline resistant mesh tape and thinset.
But when it comes to getting moist those fiber cement Board behind Tile in Shower maintain up properly. they’ll absorb water however will dry out without losing their form. because they will absorb moisture there must usually be some sort of a moisture barrier whilst the use of these tile backer forums in a shower or different moist region. either a vapor-kind barrier behind the board or a waterproofing membrane on the front. this could take the shape of a sheet membrane or a paint-on liquid.
Board behind Tile in Shower – Cement Board
Popular Cement board brands are Durock, Wonderboard, and Permabase. just like the fiber cement boards, these may be tough to cut. the issue comes now not so much from the stiffness however the edges that disintegrate. It does take some getting used to. and they’re heavy. And difficult to maintain on the wall even as you begin your screws.
Cement forums have advanced over the previous couple of years. the rims don’t crumble as bad as they used to. Permabase is the one that I opt for and i can typically force screws into the very facet with out it breaking off. also, the water absorption is pretty low. you continue to need to water-resistant them just like the fiber cement forums above. And use the same screws and mesh tape.
Foam Tile Backer Board
Wedi board is probably the most famous if, for no other purpose, that it’s been out the longest. Kerdi Board is any other choice with a decently lengthy history and constant customer base. greater these days, USG Durock foam board, Laticrete Hydroban Board, and Johns Manville GoBoard have all come available on the market.
There are some huge blessings to those panels for showers: they’re light-weight and don’t harm the partitions as you carry them into the residence and upstairs. they’re simply smooth to cut and the board itself is water-proof. No want for extra waterproofing. some forums will need additional framing blocks at the seams. Wedi Board behind Tile in Shower seems to be stiffer than most.
the primary drawback is the cost and maybe availability. the froth board itself is normally three instances the value of cement board. you then have to buy the urethane sealant which you use in among the joints of every panel (or banding for merchandise like Kerdi-board). And the immaculate screws and unique washers. All that stuff adds up – and rapid.
How to Install Tile Backer Board
Half-inch cement backer board is ideal for most tiling jobs, including walls, floors, countertops, and ceilings. For flooring, the backer board should be installed over a 5/8-inch thick OSB or plywood base. For countertops, use 3/4-inch plywood beneath the backer board. And for walls and ceilings, apply 1/2-inch or 5/8-inch backer board screwed directly to the wall studs or joists.
You can cut cement and gypsum backer board with a jigsaw fitted with a carbide blade. If you’re installing backer board on the subfloor or over an existing substrate on the wall, apply thin-set mortar to the sub-surface and comb it out with the notched side of the trowel. Press the backer board firmly into the mortar, then screw it to the sub-surface, placing screws around six to eight inches apart. Use screws specifically designed for your type of backer board, as recommended by the manufacturer. Sink the screw heads slightly below the surface of the backer board.
Maintain a 1/4-inch distance between backer boards and along the perimeter of the wall. Stagger the seams for added strength and durability, ensuring that you don’t have four corners meeting in one place. When all of the boards are installed, fill the joints with thin-set, and smooth them with the flat side of the trowel so that the thin-set extends a couple of inches on either side of the joint. Cover the seams with fiberglass seam tape, removing excess adhesive from both sides of the tape as you go. Then, spread adhesive over the tape, using just enough to cover the tape while ensuring a smooth transition to the backer board. Allow the adhesive to set before installing the tile.
Why Backer Board is Essential for Tiling Jobs
Laying tile directly on a surface like plywood or an existing floor can cause major problems down the road. Tile installed directly over wood will likely buckle as it absorbs moisture, and the wood will be susceptible to mold and mildew. Additionally, wood substrates expand and contract with temperature and humidity changes, which makes it an unsuitable surface for tile. Tile laid directly over an old linoleum or vinyl floor may shift and break if the surface contains air pockets or is susceptible to moisture. Laying tile directly on an existing floor can also cause problems if the tile is very heavy or will be supporting heavy furniture.
When to Use a Backerboard
Tips on Installing Shower Floor Trays Whenever the steam from a warm shower hits the cool air in the rest of the bathroom, condensation occurs. When you get condensation behind your shower enclosure, it can lead to mold, mildew, swelling of the studs in the wall, and other problems. Moisture and condensation are the two biggest problems to contend with when building a new shower. Prevent these problems before they occur by installing some type of moisture or vapor barrier every time you build a shower.
What Moisture Barriers Do
No matter how watertight you think your shower is, moisture in the form of water vapor may still get in. A seam in an acrylic shower or a cracked grout joint or some missing caulk in a tile shower are all that is needed to let moisture get behind your shower enclosure. Moisture barriers stop that water or vapor from getting any farther and potentially rotting your studs, the drywall or greenboard installed behind the enclosure. They are required beneath your shower pan and behind your shower walls. Moisture barriers can be made of polyethylene or a membrane that is rolled directly onto the drywall. No matter what they are made of, without them, your shower is subject to moisture damage.
The thinking is that as long as there’s a completely waterproof membrane on the front of the sheetrock that the sheetrock will never get wet. Many local building codes do allow for greenboard as a tile substrate in showers. Contrary to popular belief, ceramic tile and grout, by themselves are not waterproof. The problem is that water does seep through grout joints and gets the drywall damp. Mesh Tape: Don’t skip this step But when it comes to getting wet these fiber cement tile backer boards hold up well. Plywood also isn’t considered a backer board, although it’s often used as the substrate for tile installations. You should, so that any moisture that gets behind the cement board runs into the tub or shower instead of into your wall cavity (causing rot or mold/mildew). Since plywood is often used as an underlayment for floor tile, some do-it-yourselfers may believe that it can also be used in shower wall applications. Use tile spacers between the tile to make sure the gaps are consistent. Unacceptable Shower Backer Boards Several traditional tile installation methods used materials that are no longer considered acceptable for shower applications. Plywood alone cannot be used as a substrate under tile in showers. If you plan to cut the bottom row of tile, start your installation with the second row. But they both perform essentially the same function: to provide an underlayment for tile over a subfloor. Fiber board is recommended for floor tile installations, since thin-set mortar adheres well to it, ensuring a strong tile-to-floor bond. It’s not the best choice for larger-format floor tiles. Tile Backer Board Half-inch cement backer board is ideal for most tiling jobs, including walls, floors, countertops, and ceilings. Tile Backer Board Half-inch cement backer board is ideal for most tiling jobs, including walls, floors, countertops, and ceilings. Liquid Membranes Liquid membranes eliminate much of the hassle of installing prefabricated sheet membranes. Waterproof sheet membrane such as Schluter Kerdi is applied to the cement board with thinset adhesive. After the thinset has dried, tile is applied to the sheet membrane with thinset. The facing serves as an integrated waterproofing membrane, so you don’t need to install a separate layer of plastic behind the tile backer or a sheet membrane over the backer. The criteria applies to liquid-applied and sheet membranes used as barriers to positive liquid water migration in load-bearing, bonded, thin-set installations of ceramic tile and dimension stone on floors, and as shower sub-pan lining. Water-resistant drywall is a good backer board choice behind sinks and other places where occasional splashing and high humidity could affect regular drywall. It takes just a little moisture for drywall’s paper facing to disintegrate and turn moldy.
