Using a smaller paintbrush, I painted a full coat onto the pattern and then once it was dry, I added a second coat. I wanted good coverage, but not 100 solid.
I then focused on the areas closest to the walls. I cut my stencil in half and cut those into pieces. I used the pieces I needed to paint right up against the walls.
I painted on the sealer with a paint roller. How many coats is up to you. I personally did three coats of sealer. This brought out a deeper color to the floors.
