  • Masonite Siding 101: Why It's Bad News
    Moving into a new home is a great feeling of accomplishment. Fixer-uppers have been a trend in the real estate market for some time now, and for a great reason. Often minor cosmetic adjustments to homes can have a major impact. But what happens when you find a problem that isn’t so DIY-friendly? Discovering masonite siding, also known as "fiberboard" or "hardboard", may unearth more serious problems for an older home. Masonite Siding 101: Hardboard is an engineered wood product that is comparable to particle board. This product is made from compressed wood fibers so it does not have a grain like solid wood. However, a wood veneer may be formatted over the product so it appears to be solid. If you’re unsure if your siding is in fact masonite, check unfinished areas like the attic for manufacturer’s markings. Another way to tell that your home has Masonite is the way that it is deteriorating -- look for flakes, curls and swelling in damaged areas. Masonite is know for extensive use in various industries for its durability and flexibility. During the 1980s and 1990s this product was used as exterior siding for many new construction homes. It was widely used for its low cost compared to regular siding material. Why It's Bad News: As one could imagine, a product with fibers is easily susceptible to moisture damage. The compression process often leaves only one side of the product smooth which proves to be a greater risk for water issues. Over time, masonite swells and rots if continuously exposed to the elements.

  • Density, Modulus of Elasticity, Creep, and Durability of Hardboard A
    Density, Modulus of United States Department of Agriculture Elasticity, Creep, Forest Service Bibliographies and Durability of and Literature of Agriculture 126 Washington, D.C. Hardboard February 1994 A Bibliography Abstract The references in this literature review cover four areas related to hardboard: (1) density or specific gravity,, (2) modulus of elasticity (MOE) and stiffness, (3) dimen­ sional stability and water resistance, and (4) weathering and accelerated aging. The purpose of the literature search was to provide a starting point for discussing directions for suture research and ways to improve the performance of hardboard products. The annotations encapsulate important research results. The majority of the references are grouped first by research area and then by type of hardboard fiber-mat forming process (dry, wet, or dry and wet processes). The final section of the publication includes references on North American hardboard standards and test methods for both dry and wet processes. The study on which this publication was based was funded by the American Hardboard Association, Palatine, Illinois; U.S. Department of Agriculture, Forest Service, Forest Products Laboratory, Madison, Wisconsin; and Illinois Agricultural Experiment Station, University of Illinois, Urbana, Illinois. Acknowledgement The compilation of this comprehensive bibliography would not have been possible without the assistance of many individuals Particular thanks are given to J. Dobbin McNatt and Gary C. Myers, U.S. Department of Agriculture, Forest Service, Forest Products Laboratory, Madison, Wisconsin, and Damon H. Lipinski, Research Assistant, Department of Forestry, University of Illinois, Urbana-Champaign, for their reference search, help in locating original sources, and review.

    A Sure-Look Home Inspections 3025 Mill Stream Court, Matthews, NC 28104 Tel: 704-488-4469 Fax: 704-882-8879 [email protected] www.asurelook.com FACT SHEET: MASONITE HARDBOARD SIDING Hardboard , also called high-density fiberboard , is a type of fiberboard , which is an engineered wood product. It is similar to particleboard and medium-density fiberboard , but is more dense and much harder because it is made out of exploded wood fibers that have been highly compressed. It is referred to as Masonite in the USA because that was the first brand to be marketed there in the 1920s (25 years after it was invented in England). Unlike solid wood , it is very homogeneous with no grain. However, a wood veneer can be glued onto it to give the appearance of solid wood . Other overlays include formica and vinyl . It has many uses, such as a substrate, but unlike plywood and solid wood, it has no significant structural strength. It is used in construction , furniture , appliances , automobiles and cabinetry , and is popular among acrylic and oil painters as a painting surface due to its economical price (though it must be coated with gesso or canvas before use). It is also used as the final layer in many skateboard ramps and the half- pipe . Hardboard is produced in either a wet or dry process, which produce a panel called S1S or S2S respectively. The wet process only leaves one smooth side, but dry processed hardboard is smooth on both sides. Like other types of fiberboard, hardboard is susceptible to moisture damage and is generally not used outside.

Rowell 2 1 Forest Biopolymers Science and Engineering, Forest Products Laboratory, USDA Forest Service, Madison, WI 53726, USA 2 Biological Systems Engineering, University of Wisconsin, Madison, WI 53706, USA; [email protected] * Correspondence: [email protected] Abstract: The first research on acetylation of wood started in 1928, and the first research done on acetylation of wood at the USDA Forest Service Forest Products Laboratory (FPL) started in 1945. This is a review of the research done between 1945 and 1966 at the FPL. This research was the first to show that acetylated wood was both decay-resistant and dimensionally stable. It was the pioneering research that ultimately led to the commercial production of acetylated wood. Keywords: history; decay resistance; dimensional stability; acetylation 1. Introduction The first experiment in the acetylation of wood was in Germany by Fuchs in 1928 using acetic anhydride and sulfuric acid as a catalyst [1]. Fuchs found an acetyl weight gain of over 40 percent, and he used the acetylated wood to isolate lignin from pine. In the same year, Horn acetylated beech wood to remove hemicelluloses in a similar lignin Citation: Ibach, R.E.; Rowell, R.M. isolation procedure [2]. In addition, in 1928, Suida and Titsch acetylated powdered beech USDA Forest Service Forest Products and pine using pyridine or dimethylaniline as a catalyst to yield an acetyl weight gain of Laboratory: Acetylation of Wood 30 to 35 percent after 15 to 35 days at 100 ◦C[3].

Even after old glued down carpet has been removed, and the subfloor has been scraped, it should NOT be assumed that the concrete is porous. Often the old adhesive has sealed the floor. A porosity test, using water, should be taken. Be aware that porous subfloors may take a different adhesive than non-porous subfloors. See adhesive instructions. If oil, grease, or other contaminants have deeply penetrated the concrete, and cannot be thoroughly removed, Shaw cannot be installed. If latex liquid has been used to seal off old cutback adhesives, the concrete has become non-porous. b. Lightweight concretes: Concretes in the lower end of this range are generally used for thermal and sound insulation fills for roofs, walls, and floors. The higher densities are used in cast-in-place walls, floors, roofs, and for pre-cast elements. The minimum density of the concrete should be greater than 90 lbs per cubic foot. The minimum compressive strength should be 3,500 psi or greater. Gypsum-based concretes are not recommended. If installing over gypsum or other forms of light concrete always apply an Acrylic based Primer-Sealer coat before toweling adhesive.
