How We Finished the Playhouse Interior

While we were super excited to be moving inside the playhouse, there is still a ton of work to get done! Boarding up the walls, painting, tiling, adding railings and ladders to the loft, etc. etc.

We started by board up all of the walls. And if it feels like we didn’t accomplish all that much this week, it’s because boarding up the walls took a long time.

We decided to board up the house with hardboard instead of drywall, because it would actually stand up better, and was faster to finish. We’ll never be able to get really smooth seams with hardboard, but it’s a playhosue so we weren’t being too picky, lol.

A couple of the walls needed a bit more structure than hardboard. We wanted to put up particle board behind the wall that we were tiling on because we didn’t think the hardboard could handle the weight of the tile.

We also wanted to add particle board behind another wall that would be getting rocks for a rock climbing wall. We knew that the hardboard wouldn’t be enough structure for the rocks to tie into securely.

Finishing the playhouse interior

Once all of the boards were up, we trimmed out the windows, framing them beautifully, and then we got ready to paint.

Painting the interior of the playhouse

We used our Flexio 5000 to paint the entire interior because it’s so fast and easy. We had to do a prime coat first, then wait at least an hour and then paint the final coat.

We sealed up all of the windows, and the door opening. All of the prep work took about 30 minutes total.

We used the Flexio 5000 with the Kilz primer, which went on so nicely! Sometimes you have to water down primer when going through a paint sprayer because it’s usually thicker. We were painting on a humid day and we did have to add a little water to thin out our primer, and then we sprayed the whole playhouse easily.

Once the primer coat was done and set, we used the Flexio 5000 to spray the paint. We used the colour Bit of Sugar by Behr paint and it looks amazing on the walls!

Using paint sprayer to paint playhouse interior

We only did one coat of primer and one coat of paint, and it was definitely enough.

If you’ve never seen a paint spray in action, here’s how to use it:

The interior looks soooo good! The paint went on smoothly, and the colour is light and bright! We couldn’t ask for anything more!

Next, we had to finish the interior of the door. We sampled a few different stain options, and then choose to go with the stain sunbleached, and added espresso overtop.

Staining the playhouse interior door

When we added the stain duo onto the door, it was a little darker and more grey then we thought it would be, but it looks amazing against the black on the other side.

Adding membrane to the floor for tile

Finally we laid down the membrane to get ready for tile. We laid the membrane first because we are using a mosaic tile on the floors.

Exciting Interior Deliveries

Finally we had a few fun deliveries this week that we wanted to share.

Jeffrey Court tile for the playhouse

We had our tiled delivered and are so excited to install it! Where better can you put a beautiful bold hexagon mosaic tile than in a kids space!

The mini black subway tiles are for the “backsplash” in the miniature kitchen and I can’t imagine a cuter tile for the space.

All of our miniature furniture also arrived! The kids were so excited to try out all of their new furniture, and I was more than excited to unwrap it all! These little pieces will be in the playhouse next week!

Small modern kids kitchen

And last but not least, here’s the mini kitchen! My husband and I are basically living vicariously through our children these days. So excited to see it all come together next week!
