Renovation Series - Removing and Reinstalling Insulation and Concrete Boards


Looking for a how-to on removing and reinstalling your insulation and drywall, look no further! The team at Appliance Educator just released a new blog series and we’re excited to bring you the next blog in the Renovation Series. One of our Appliance Educators recently started renovating his bathroom and has created a complete tutorial for each step in the renovation process.

Last week, we kicked off our bathroom renovation and tackled the shower tile. This week, our Appliance Educator will show you how to remove the old insulation and drywall and install new material. Let’s get started!

Since our Appliance Educator removed the shower tile last week, he still had the existing cardboard and plastic wrap available. Make sure to keep your renovation area clear of any sharp tools or materials that you won’t be using anymore, and it’ll help keep your waste to a minimum. To begin removing and reinstalling the insulation and drywall, you’ll need: 

  1. Safety Goggles/Glasses
  2. Safety Mask 
  3. Heavy-Duty Work Gloves
  4. Tape Measure
  5. Blade or Slicing Tool
  6. Electric Drill
  7. Concrete or Wood Screws
  8. Insulation (Can be purchased at local hardware store)
  9. Cement Board (Can be purchased at local hardware store)
  10. Ardex 8 + 9
  11. Paint Roller or Paint Brush 

Our Appliance Educator purchased a giant roll of insulation from his local hardware store. Using a tape measure, he measured out where each piece of insulation would go within the walls and cut out the needed dimensions with a sharp blade. You don’t need to cut out the insulation exactly to size. It can be helpful to add an extra inch to both the length and width of your measured piece. This will ensure a snug fit that isn’t too tight. 

You’ll want to be cautious of any insulation pieces folding or creasing. Proper ventilation is important towards the longevity of your home. A home that is too insulated can build up moisture over time and cause mold and low air quality. 

After securing the pieces of insulation, our Appliance Educator installed cement boards over the insulation. He decided to use the cement board because of its incredible durability. Cement boards are ideal for rooms in your home that are susceptible to moisture, like the bathroom and kitchen. It’s crucial for you to install the backer board as level as possible. This will make it easier when it’s time to install the tile. 

Our Appliance Educator then directly installed the cement boards onto the studs and painted Ardex 8 + 9 solution over the boards, then let it cure for an hour and a half. For more information on what Ardex 8 + 9 is, please click this link
