Why Drywall Isn’t the Answer When Renovating Your Basement 

Wednesday, December 29, 2021

Drywall performs poorly in damp, wet environments, making it a poor wall or ceiling choice for a basement renovation. Instead, consider PVC-based products like Trusscore Wall&CeilingBoard and Trusscore SlatWall, products designed to deliver sharp-looking, functional, and long-lasting results in a basement use-case.  

When Drywall Gets Wet, Problems Erupt

Basements, because they’re below grade, are often damp. They’re prone to flooding. They’re prone to water seepage through the exterior walls. They’re prone to drains backing up. And the moisture content of the air in a basement, particularly during the summer when furnace heat isn’t assisting in keeping the space dry, is higher than the rest of the house. 

The problem with drywall in a basement is that, with all that moisture, the drywall gets wet. And stays wet. And when drywall gets wet, problems erupt. 

As soon as moisture reaches drywall, the drywall begins to swell, expand, and show water marks and discoloration. The only fix is to rip out the drywall and replace it. You’re quickly committed to the process of taping, mudding, sanding, a house full of fine drywall dust and, finally, painting. And will the new paint match the rest of the room? After plenty of expense and disruption, if the underlying water problem isn’t solved conclusively, you may well be forced to replace all the drywall again down the road. 

But there’s more. 

Drywall is predominately made of gypsum which is sandwiched between layers of paper. When gypsum and its surrounding paper layers get wet, the drywall sheet loses its structural integrity. The gypsum turns pasty and crumbly. Again, replacement is the only viable option. 

An even bigger problem looms in the shadows – literally in the shadows. Combine dark basement spaces, moisture, and drywall, and you’ve got a sure-fire recipe for mold. Why? The paper layers of a sheet of drywall contain cellulose. Mold uses drywall’s cellulose-based paper, and its component sugar and starch, as a food source. Mold thrives on cellulose, in other words. 

Mold, of course, can cause a myriad of nasty health issues. Again, the remedy? The drywall must be ripped out. More taping, mudding, sanding, dust, painting, and expense. And then pray the underlying water problem doesn’t manifest later and start the mold engine up once again. 

The Perfect Alternative to Drywall in a Basement 

The answer – the sensible answer – is to not use drywall at all and instead use a drywall alternative like Trusscore Wall&CeilingBoard and Trusscore SlatWall, products that are far more suited to a basement environment. Trusscore products are PVC-based. There’s no cellulose. They won’t, therefore, support the growth of mold or mildew in your basement. 

Trusscore products are unaffected by moisture. If your basement were to flood, or if moisture became a problem and the walls were to get wet, the PVC wall and ceiling panels you’ve invested in will remain unaffected. If the flooding left them stained, dirty or discolored, a simple wipe down with a common household cleaning product would make the panels like new again. 

Trusscore Wall&CeilingBoard installs easily, four times faster than drywall, and therefore with less expense, perfect for the do-it-yourselfer. There’s no tape, no mud, no sanding, and no painting. 

Another consideration when evaluating wall options for a renovation is that basements tend to be dark, a function of being below grade with small (or no) windows. Trusscore Wall&CeilingBoard panels come in a bright white finish – no painting required – which enhances and reflects the available light. A stylish gray color option is also available for those looking to add a warm, welcoming feel to their space.
