Cementboard is a popular choice for flooring, siding and many other functions. This material, also known as concrete board or cement backer board, is one of the most popular choices for flooring, siding and many other functions. Here are ten facts you need to know about cementboard.

Cementboard is one of the most commonly used materials in construction today. The material is made from compressed Portland cement and fibers, which can either be wood or fiberglass.

The fibrous design of the material makes it extremely durable. Cementboard lasts longer than drywall and comes in a variety of forms ranging from 1/4 inch to 1 inch thick.

Cementboard is often used as an alternative to traditional drywall due to its durability and water resistance. The material is also resistant to mold and mildew, making it a great choice for bathrooms, kitchens and other areas that may experience moisture over time.

One of the biggest selling points for cementboard is its fire resistance. Unlike drywall, which quickly ignites when exposed to flames, cementboard will not burn on its own. If a fire occurs near cementboard, the material will withstand the flames for long periods of time without burning through.

Cementboard can be cut with

1. What is Cementboard?

Cementboard is a combination of Portland cement, silica, quartz sand and fiberglass mesh to form a panel that is used in construction as an underlayment for tile. It is typically used for flooring and countertop applications.

Cementboard has been around for many years, but has gained popularity in recent years due to the increase in tile installations.

2. Why Use Cementboard?

Cementboard was developed as an alternative to traditional backerboards such as 1/4″ or 1/2″ thick gypsum board, lauan plywood or particle board. These traditional materials have not performed very well in wet areas because they are susceptible to moisture damage. Cementboard is more water resistant and more durable than these backerboards, which makes it an ideal substrate for use with tile and other finishes that require a stable base material.

Cementboard is a combination of cement and reinforcing fibers formed into 3 foot x 5 foot sheets, 1/4 to 1/2 inch thick that are typically used as a tile backing board. Cementboard can be nailed or screwed to wood or steel studs to create a substrate for vertical tile and attached horizontally to plywood for tile floors, kitchen counters and backsplashes. It can be used on the exterior of buildings as a base for exterior plaster (stucco) systems and other exterior finishes.

Cementboard was invented in the early 1900’s as an alternative to gypsum drywall for wet areas like bathrooms. Drywall can’t stand up to water, so it had to be covered with greenboard or cementboard before tiling. But cementboard quickly became popular even where drywall would work because it’s so much stronger and more durable. Today, cementboard is used in all kinds of construction around the world.

The first step in working with cementboard is cutting it down to size — it comes in 3×5 foot sheets that are too big for most uses. You can cut cementboard with a carbide tipped scoring knife or a circular saw with a masonry blade. I prefer the scoring knife because it gives me better control

Cementboard is an extremely durable, moisture resistant and versatile substrate that can be used in place of traditional drywall. Cementboard is the preferred substrate for the installation of tile, stone, marble and other finishes that require a stable and flat substrate.

Cementboard can be used on exterior applications as long as it is properly flashed and coated with an approved coating system. Cementboard has also been used as a replacement for plywood in vanities and kitchen countertops.

The versatile nature of cementboard makes it one of the most useful building materials for construction professionals, but there are a few things you should know about cement board before you begin your next project:

1.Cementboard is the perfect choice for bathroom walls and floors because it’s waterproof, not just water-resistant.

2.If you are tiling a kitchen countertop, cementboard is your best option.

3.Cementboard is the easiest backer board to cut thanks to its uniform composition and can be cut using a knife, making it perfect for creating irregular cuts around sinks and toilets.

4.Cementboard adds strength and rigidity to floors and prevents cracking in ceramic tile and natural stone installations.

5.Homeowners should choose cementboard instead of drywall for shower surrounds or tub backsplashes because drywall soaks up moisture from the shower or bathtub and will degrade over time.

6.Use a fiberglass mesh tape on all joints of cementboard as an added layer of protection from possible cracks in the future.

7.The best way to install cementboard is with corrosion-resistance screws because they provide a tight hold that prevents movement, which leads to cracked tile or grout lines; screws also make it easier to remove old tiles down the road when you want to remodel your bathroom or kitchen.

8.Always choose cementboard that has been certified by an independent testing agency like ICC-ES (

Cementboard is a great building material for all sorts of projects. While it’s not the only type of cementboard out there, it’s one of the most common types used in construction because it’s durable, easy to install, and cost-effective.

Cementboard is different from other types of building materials like softwood. Because of its durability and strength, this makes it ideal for a wide range of projects. It can be used to build things such as concrete walls or even outdoor decks or patios. In addition to being durable and strong, cementboard has many other benefits as well. Some of these include being fire resistant (which means it doesn’t burn easily) and having excellent water resistance properties.

Cementboard is also widely used in construction because it’s lightweight and easy to use. This makes it an ideal choice for many applications where traditional materials might not work well due to their weight or difficulty with installation.

Cementboard is a composite of Portland cement, aggregate, and glass mesh that provides an exceptionally hard, durable surface that is able to withstand prolonged exposure to moisture. Cementboard has replaced gypsum-based drywall in many tile installations, such as tub or shower surrounds. This is because cementboard can be exposed to water without softening or breaking down.

For the most part, cementboard is similar to drywall. It can be cut with a utility knife and fastened with drywall screws (although special cementboard screws are also available). It comes in 1/4″ and 1/2″ thicknesses and 4′ x 8′ sheets. The biggest difference is that cementboard requires waterproofing around bathroom fixtures like toilets and tubs.

Some manufacturers make a product called “backer board” which contains no Portland cement. These products are not appropriate for use as a tile underlayment.
