We have def been creative with all the wood and other finds we have on the property. Panels from the sauna fit perfectly in the area below the loft – although Brian did have to modify the length. I painted them with acrylic paint mixed with Flotrol (a paint additive used to make the paint flow better). It’s easy! Just mix each color in a cup with 1/2 Flotrol and 1/2 paint and pour over the “canvas”. I try to buy “oops” paint from Home Depot and Lowe’s – its cheap and has more pigment that craft paint. I used my fingers, but no paint brushes to get the look I wanted.
I used this same technique on canvas. Mix the acrylic paint with Flotrol (1/2 and 1/2). I love to use cheap squirt bottles I got on Amazon (or if you live near a Dollar Tree). The biggest tip I can give is to let an area dry before you start the next area if you feel it is starting to get muddled. This is especially useful on large paintings.
I was lucky enough to find a used surfboard on FaceBook Marketplace for 40 bucks and painted it with a scene from our property. I never claim to be a great artist, but I do what makes me happy. And if I don't like something I paint over it!
