If you’re on a tight budget or want shiplap in an RV, then Sharpie shiplap might be the option for you. In each of my RV renovations, I’m always looking for ways to save on adding unnecessary weight. Sure, I think real shiplap looks a lot better; however, typically you need to make some design sacrifice’s to make sure you do not exceed the GVWR (Gross Vehicle Weight Rating) of the RV. So Sharpie shiplap is my easy solution to get the look and will only cost a few dollars!
Figure out which direction you would like to run the lines, then with your pencil and yardstick (or tape measure), mark a small tic at every increment across. In my case, I made the plank’s 6″ wide, so I made marks every 6, 12, 18, 24, 30, and 36 inches. Repeat this process across the wall.
Line up your yardstick with the pencil marks and run the Sharpie along the edge. You’ll need to do a couple of passes with the Sharpie to make sure the line has no gaps. Also, don’t apply too much pressure to the sharpie as the ink won’t flow easily. Sometimes you may need to rotate the Sharpie to ensure the felt tip is full of ink.
Important: For continuous lines longer than the yardstick, reduce pressure on the Sharpie as you reach the end. This will feather the line out, so once you shift over the yardstick, the start of the next line section will blend into the first.
Be patient and take your time. The less textured your walls are, and the slower you go, the cleaner your lines will look. If you make a mistake, touch the wall up with some paint and a small paintbrush. Also, start in an area that is not visible to you get the hang of it. Practice makes perfect. Best of luck!
