Next, use your 6 inch taping knife to knock down any peaks or high areas on your current texture. I was skim coating in a room with carpet so I laid down 3 millimeter plastic and taped it along the perimeter of the room. To get started, prep your space by covering your floors with plastic (if needed!). I did not feel like I could get a smooth finish like I could with a drywall knife. If you notice in my picture, I was originally using a Magic Trowel after seeing so many recommendations.

It is definitely labor intensive, but it’s doable for a DIYer! Materials NeededĮveryone has their preferred tools to skim coat, but this is what I found worked best for me. The joint compound fills in the low areas of the texture! I was so nervous to give skim coating a shot. So what is skim coating? A skim coat is when you apply diluted joint compound to the walls and smooth it out with a drywall knife. This is what our knockdown texture looks like. I figured, let’s just skim coat the entire room! And that’s what I did. In my opinion, board and batten looks much more professional with smooth board sections rather than texture. The bottom of the walls we did a double board and batten. I knew it was best to skim coat over the texture for the wallpaper section on the tops of the walls.
DRYWALL SKIM COAT THAT STICKS TO PAINT INSTALL
It is recommended to install wallpaper on fairly smooth walls for better adhesion and so you don’t see the bumpy texture under the wallpaper.

We just completed a fun little makeover in our oldest two boys’ room and the number one question I have received over on the gram is “Why did you skim coat the walls?” We live in Texas and we have very heavy knockdown textured walls.
