For any painted furniture, cabinets, wall paneling and some molding, the MDF are definitely the best material you can get. The surface faces come from the factory and are sanded to about 150 grit or better than that and that they are paint-ready. Usually, some people scuff-sand the surface fast with about 120 grit or 150 grit sandpaper in order to get rid of any dirt as well as grime to provide a much better adhesion of the primer coat.
Benefits MDF Spraying
One of the advantages regardless of priming or painting MDF is its density, which means, there’s no grain. Whenever you add these features together, the surface of the woods will end up being unblemished and smooth, most especially when they are properly coated. Other strong points for using MDF will be the lowest cost that it provides. It eases the use of cutting and stiff, sturdy properties, once used in building shelves or cabinets.
There are many disadvantages when you are priming and painting MDF or even with using other kinds of fiber board. MDF is made with a substance known urea formaldehyde. Thus, face masks, proper ventilation and goggles must be worn when shaping, sanding or cutting MDF. A mask must also be worn when using an electric type of machine in order to do any of the jobs mentioned.
Use a solvent-based primer
Solvent-based primers like alcohol, oil, or lacquer based are a must. You must never use a water-based product for the initial finish coat. The wood fibers will swell too much when they absorb water and you’ll surely get what is, in effect, raised the grain on the surface that will not sand out. Once the surface has been sealed with something else, a water-based paint will not simply affect the MDF in a bad way.
Prepare the porous edges
The only problem that will take place when doing MDF spraying is what to do about the edges, which are more porous than the surface- similar to the end grain of lumber and drink in most of the finish. There are actually woodworkers who go to the trouble of edge-banding the MDF. That approach actually takes more time than other methods, and no matter how well the edge-banding has been trimmed and applied, a seam may still show at the edge.
There’s also drywall compound that you can use to fill the edges. Whether they are cut in different shapes using the router bit, you can liberally apply the compound using your finger, or with the palm of your hand. As compared to the conventional or spackle wood putties, drywall compound also has its soupy texture, so it will be a little sloppy. However, the moment it dries, it easily sands off. For the edges being shaped using a router, you could surely use the same router bit, as a scraper to remove the excess globs of compound prior to touching up the edges using a 220 grit silicon carbide sandpaper.
