How to install cement boards on walls?

  • 3 × 5-foot sheets of cement board are the most typical size for this product, and thicknesses range from 1/4 inch to 5/8 inch. About 30 pounds of 1/4-inch cement board weighs a 3 by 5 panel, and 36 to 44 pounds of 1/2-inch sheet. 
  • However, even though larger panels up to 4 x 8 feet are available, the added weight renders them unsuitable for DIY installation.
  • You’ll need to cut your cement board into a variety of sizes in order to complete your job, and understanding how to do so in advance can save you from making mistakes that may prove expensive. A utility knife and a T-square work well for cutting cement boards. 
  • Two or three passes with the knife and a square establish a straight line on the cement board, then snap the waste region of sheet back to break the cement board along the slicing line are common methods of scoring. 
  • Complete the cut by cutting the fiberglass mesh along the rear of the board, if appropriate. Drill and hole saw bits may be used to create round or curved cuts on jigsaws equipped with carbide blades.
  • Organize the Installation in advance. Based on the size of the cement board sheets and the area to be covered, make a preliminary layout design for the cement board sheet. 
  • At least 8 inches of plywood (or equivalent) subflooring should be offset by the seams between the sheets for best floor rigidity. Plan to start the first row of sheets with a partial sheet if required to generate the offset. Plan to start first row of sheets
  • Make a Mortar and Spread It. As instructed by the manufacturer, prepare a small batch of thin-set mortar by mixing dry powder with water in a bucket. Apply a mound of mortar to the subfloor, then use a 1/4-inch notched trowel to smooth it out evenly. 
  • Set up the first sheet of cement board on a small patch of ground. Install the first sheet. The first sheet should be placed on top of the mortar bed. Should face up, depending on if it has any kind of texture or embossed pattern on it. 
  • All surrounding walls should have a 1/4-inch space between sheet edges and the edge of the sheet itself. This may be done using a drill-driver, ensuring that the screws are either flush with or slightly recessed on top of each other. The screws should be spaced 8 inches apart across the sheet.
  • Add Additional Sheets. First row sheets should be laid and fastened 1/4 inch apart and with a 1/4-inch space at all walls, using mortar and the same procedures as for the first row.
  • The Last Set of Sheets to Go In. Until you’ve covered the whole surface, keep putting up sheets. A 1/4-inch gap between cement board sheets is a good rule-of-thumb when installing it over plywood. 
  • If you don’t use the fresh mortar in time, it will dry out, preventing you from using it. Tape and mud the joints. Apply self-adhesive cement board joint tape to all of the gaps between the sheets. 
  • Apply a thin layer of thin-set mortar to the taped joints with a drywall knife, just like you would when mudding drywall joints. Apply the knife to the mortar so the tape is firmly adhered and the joints are smooth. As directed by the manufacturer, let the mortar cure completely before using.

How to install HardieBacker Cement Board on concrete walls?

  • Install your Hardiebacker cement boards a quarter-inch above the floor, tub, or shower board and caulk appropriately.
  • Nail or screw cement board to all supports at a maximum distance of 8 inches on center.
  • Board edges should be kept at least 3/8″ from fasteners, whereas sheet corners should be kept at least 2″ away from the fasteners.
  • Set the head of the fastener flush with the surface without overdriving it.
  • Install 2″ wide, high-strength, alkali-resistant glass fiber tape over the mortar and level it.
  • You’re now ready to cover your walls with stone or tile. In order to complete your task, follow these steps:
  • Use a moist sponge to clean the HardieBacker Cement Board’s surface.
  • Use a notch trowel with the suitable size to spread your mortar. Comb the ridges in a single direction exclusively for optimal outcomes.
  • The third step is to twist or push the tiles and beat them.
  • Before grouting, let the cure sit for at least 24 hours.

What is a cement board?

Construction material composed of cement and glass fibers and reinforcing fibers that is rolled into a sheet is known as “Cement board”. Cement board sheets are normally 3 feet by 5 feet in length, although they may also be purchased in 4 foot by 8 foot lengths. 

It is common for cement board sheets to have thicknesses of 14″, 12″, and even 5/8″. In most cases, 14″ cement boards are exclusively utilized for flooring. Larger thicknesses may also be employed as floor coverings because of their strength and durability. 

The most typical use of cement board is as a substrate for tiling walls or floors. Outside of structures, cement board is also utilized to protect the structure from the elements. Gypsum board is less durable and less water resistant than cement board, which is why it is utilized in the majority of wet environments.

With its exceptional moisture resistance, impact resistance and strength, cement board should be utilized for shower walls. When tiling bathroom walls, cement board should always be utilized. 

As long as the bathroom isn’t tiled and a lot of water isn’t expected, you may utilize gypsum board for the bathroom walls. We’re ready to get started installing the cement board now that we know what it is, why we need it, and the supplies and equipment we’ll need to get the job done.

Cement board arrangement is an important consideration before you begin placing it on the walls. To begin, make certain that all of your cement board’s edges rest on a stud. If not, you may need to add extra studs or blocks.

Use as many complete sheets as feasible of cement board to make installation a little bit more straightforward. The better off you are, the less cutbacks you have to make. Snap a chalk line if you need to visualize anything more clearly. You may do a dry fit to obtain a decent concept of the arrangement.

Conclusion

With thinset mortar, ceramic, porcelain, or stone tiles may be put on top of cement board, typically offered under trade names such as Durock and Hardiebacker. In moist spaces like showers and tubs, cement board has replaced plywood and drywall backer materials for wall tile applications.

As opposed to drywall, greenboard, or plywood (which include biological components), cement board is impervious to mold, rot, shrinkage, or decomposition caused by moisture. In terms of durability, ceramic tile installed on cement board is one of the best options.
