Performance

You want a backer board that stands up to daily use. Some boards handle weight and stress better than others. Plywood bends a little but holds heavy loads, making it great for places with lots of movement. Magnesium oxide (MgO) boards are super tough and last a long time, even in tall buildings. Fiber cement boards stay strong for decades and block fire and bad weather. Here’s a quick look at how these options compare:

Tip: If you need something for high-traffic or tough spots, MgO and fiber cement boards are your best bet.

Moisture Resistance

Moisture can ruin your project if you pick the wrong board. DensShield has a water-resistant core and a fiberglass surface that fights mold. MgO boards do not soak up water and stop mold and mildew. Glass mat gypsum boards work well in wet areas. Fiber cement panels resist rot, fire, and termites. Plywood does better than OSB but still needs sealing in very wet places.

If you’re working in a bathroom or laundry room, choose a board with strong moisture resistance.

Installation

You want a board that makes your job easier. Foam backer boards are light and simple to cut with a utility knife. DensShield is also easy to handle and install. Fiber cement and MgO boards are heavier and need special tools. Plywood is easy for most DIY projects, but you must seal it in wet areas. Glass mat gypsum boards go up fast and work well for quick jobs.

• Foam and DensShield: Easy to carry and cut

• Fiber cement and MgO: Heavy, need special tools

• Plywood: Simple for DIY, needs sealing

• Glass mat gypsum: Fast install, good for renovations

Cost

Cost matters for every project. Drywall has the lowest initial cost, but you pay more for repairs and upkeep. MgO and cement boards cost more up front and for labor, but they need less maintenance. Plywood and fiber cement boards fall in the middle. Fiber cement boards cost more to buy but save you money on repairs.

Think about your budget and how much work you want to do later. Spending more now can save you money in the future.
