Trader, September 15,, first disclosed a wallboard constructed from "Celotex", a felted mass of strong bagasse fibers, so compacted as to be capable of use as an artificial lumber in that it can be sawed and nailed, and has sufficient strength in many cases to be substituted for lumber.

That same patent mentions "Insulite", a building board made from wood pulp tailings and which likewise has a porous fibrous body portion and which is possessed of considerable strength so that the same can be nailed, etc. Celotex was preferred as an insulating material because its internal cells produce a sound-deadening insulating effect.

Patent No. Munroe et als, U. Patent 2,,, Armen H. Tashjian et als, assigned to William B. Miller, Lakewood OH, 23 May , describes insulating structural boards of laminated construction for use as roof or floor slabs, and refers to "Standard insulating fiber boards, such as "Celotex", "Masonite", "Insulite", etc.

Patent 2,,, Carl G. Muench, New Orleans, assigned to Celotex Corporation, described a method and apparatus for drying sheets of artificial heat insulating lumber, preferably formed by the felting of bagasse fiber along with other materials necessary to make a satisfactory structural fiber board. Patent 1,,, Sept. Reserve Supply Co. Quoting: Rabbeted joints in material to which plaster or other material is applied are found in the Jones patent, No. In this patent the composition is made up of plaster of paris, cement, or other like substance, combined with hair, wood fiber, sawdust, wool, wood shavings, excelsior, straw, or similar substances.

The length of the lath covers three joists instead of four. The boards are arranged in staggered relation to each other and the joints are shiplapped. The specification states that after the boards or blocks are placed in position they may be covered with wallpaper or other similar material, which, of course, would include plaster. Shaw, inventor from Minneapolis MN, describes improvements for machines for perforating Insulite Boards.

One of the most significant differences between hardboard and fiberboard panels both MDF and HDF is the method of manufacturing.

MDF and HDF panels use a dry process method and use synthetic binders or formaldehyde-based agents for binding the wood fibers. Both processes explode the wood particles using steam pressure, and float them in a large vat of water, which pulls out many of the naturally acidic agents within the wood. The wood fibers are then randomly aligned parallel to the surface, and using heat and pressure, are made into a solid core panel. This process allows a uniform and very strong panel, making it one of the best substrates for painting, laminating, and construction.

While still a relatively light-weight panel, hardboard has a significantly higher density compared to MDF panels with a much higher tensile strength and internal bond than MDF and most HDF panels. This is the most stringent accreditation in the industry. Our aspen fiber overlay provides a more pH-neutral wood content and even uniform fibers.

Medium-density fiberboards MDF and High-density fiberboards HDF are engineered panels that are made through a dry process that completely breaks down the particles of wood and reconstitutes them into a new panel using heat, pressure, and a binder. Cover the floors with a drop cloth.

Tape off floors, ceilings and trim with masking tape. Sand the surface of the particleboard with a fine-grit sandpaper until the wall feels smooth to the touch. Particleboard typically has a rough surface, which causes the paint to look patchy and uneven if it isn't sanded.

Vacuum the wall with the dusting attachment to remove any sanding residue. Vacuum along the baseboards where sawdust tends to collect. Dip the bottom third of the bristles of the angled paintbrush into the sealing primer. Seal the edges by running a generous coat of drywall compound over them with your finger.

Once it has completely dried, sand edges smooth with grit sandpaper. Fill any scratches on the face of the MDF with drywall compound as well, as any mars or scratches will be painfully obvious once painted. Sand the entire piece with grit sandpaper, then wipe it all down with tack cloth to remove fine dust and any remaining dirt or debris.

Avoid water-based primer, as it may cause the wood fibers to swell, resulting in a surface that appears to have a raised grain no matter how much effort you put into sanding. Use a brush, roller, or spray gun to apply the primer—whichever is appropriate for the project.

You can use your preferred paint on primed MDF, and you can apply the paint finish with your preferred applicator, be it a brush, roller, or spray gun—whichever best suits the project. Once the first coat of paint feels dry to the touch, assess if your work needs a second coat.
