Hello, I’m DIY Dad. ^ ^
I’m painting the ceiling white. For information on painting tools and materials, see “Tools & Materials Vol.5: Painting u2014 1) Hand-Painting.”

The walls will be finished with wallpaper. I’m hanging pre-pasted rolls with a woven texture. For wallpaper tools and materials, see “Tools & Materials Vol.1: Wallpaper Installation.”

Next up: laying the cushion floor (vinyl sheet). For cushion floor tools and materials, see “Tools & Materials Vol.2: Cushion Floor Installation.” I’m using a wood-grain pattern.

u2192 Cushion floor substrate

First, cut the vinyl sheet a few centimeters larger than the floor area. Cut out the center where the toilet drain pipe goes. Shape and adjust, then fold the edges back.

u2192 Cushion floor shaped and trimmed

Apply cushion floor adhesive to the substrate.

After the open time, lay the vinyl sheet down. Use a roller to press from front to back, working out any air pockets. Then trim the edges to match the floor shape.
