For MDF door styles, one-piece design and five-piece construction are generally the two different and most common interior construction techniques that are made. Do you want to know how? Go ahead reading. There are many benefits to choosing a five-piece door design, but let's first examine its structure. A four-piece frame (Stiles and Rails) plus a center panel make up a five-piece door. The top and bottom portions of the frame are referred to as Rails, while the two outside components are known as Stiles. If you want the high-end look of wood but are on a tight budget, 5-piece MDF doors are ideal. The fact that they are formed of many parts highlights all of the lovely nuances of the fronts' construction, particularly where the materials are joined. They often come in a variety of lovely door-style patterns. With no material connections, one-piece MDF doors are commonly cut and milled on a CNC nesting router. Five-piece MDF doors that have been painted resemble painted wood almost exactly. Western Canada's drier climate has led to a significant increase in the use of MDF in modern custom kitchens. MDF is a stable material, as opposed to wood, and does not run the danger of expansion or contraction, which may cause cracking in the finishing and joints. 
For the majority of clients, removing the possibility of cracking is a huge benefit because MDF is typically painted with a solid finish. The outside and inside of the five-piece MDF doors will be colored and polished. One-piece MDF doors can have a white melamine back on the interior of the house, thus this is a crucial difference. Both a painted interior and a white melamine interior have benefits, but those who prefer everything to match on the inside will greatly appreciate a painted interior. Doors and drawers made of five pieces of MDF are often less expensive than painted wood doors. This is so because MDF is less costly than the most common species of wood used in door making. These cost reductions will vary from company to company, but they are always welcome. When I initially began constructing things, I was really interested in how barn doors fit together. On Instagram, I would see a ton of lovely images of barn doors, but no one would ever display their backs. So, I've always been curious about things like whether we were simply gluing boards together, if there was true joinery there, what the back was like, what this was made of, etc. The answers to the questions are yes, yes, flat and ornamented, wood plywood, and MDF, and now that I've been doing it for a long, I can let you know. 
This door was created from MDF since I want to paint it. Medium-density fiberboard, or MDF, is comparable in price and use to plywood and other wood materials. Since the surface is so smooth and readily accepts paint, I like using it while painting doors since it creates a more contemporary appearance. Due to its extreme stability, MDF is also immobile and less prone to deform over time. Additionally, it costs less than plywood and actual wood. So, now that we are aware of the materials we will be using, let's get started. Have your 3/4" 4x8 MDF sheet cut at your local big box retailer to the exact door measurements you choose. This shouldn't cost you anything since they often provide two cuts without charging. Take as many bending boards (1/4" x 3 3/4" W x 96" T) as your door requires as well. Using a hand or miter saw, cut your bending boards exactly to the height of the door. You must locate the center of your door and the center of a bender board, both of which should be 1 7/8 in diameter since your door width could not be the same as mine. Make a mark on both ends of the bending board and the 3/4" MDF. Apply wood glue to the bending board's back. When you turn the boards over, the glue won't run all over the place since it dries rapidly and is applied thickly. Use 3/4" 23ga pin nails to secure it to the foundation after you have it in position. As the glue dries, the pin nails keep the board in place. 
You don't even have to fill them as it leaves such a little hole. Usually, I simply pay attention to such areas and apply a little additional primer there. Using glue and 3/4" 23ga pin nails, attach the two outside bending boards flush to the sides of the 3/4" MDF. For them, there are no measurements required. Now locate the center of each side section, mark it, and then connect the bending board in the same manner as before. Continue until all of the bending boards are uniformly spaced. In order to assure that each gap would be exactly the same width, I did it in this manner, measuring before each board. You may also use a spacer block; however, I have discovered that doing so results in the final gap being somewhat too large or too narrow due to errors in calculation or irregularities in the wood. The bending boards' sharp edges and ends should be sanded. I applied my fresh sandpaper. I like this item since it has a thick foam side that is great for rounding corners and breaking edges. The opposite side is soft foam, which is excellent for sanding curves or uneven surfaces. The sandpaper also never wears out and is simple to clean by vacuuming or blowing the dust away. And when it's finished, just throw away the paper and recycle the foam! Superb door! I used a tinted primer since I painted my door black. Additionally, I realized that it was really difficult to spray shiplap and get paint into all the grooves without drips, so I ended up brushing and rolling the primer and paint on. Therefore, roll over the shiplap after brushing paint into the grooves. 
To lessen brush strokes, you could also wish to add some to your paint. Undoubtedly, two hands are needed for this painting technique. Paint! I decided to have black paint put on me. In accordance with the manufacturer's directions, set up your barn door hardware. Make careful to place the track directly into the studs when mounting it to your wall. I appreciate the hardware set I purchased from Amazon since the track is made of a single piece and it includes all of the necessary door knobs, stops, and other items. You will need to place a backer board into the studs before attaching the track to the backer board if your studs don't line up with the holes in the track. Make sure you use real wood instead of MDF for the backer board since it is more durable. These prime boards are great to use.
