Wood & Adhesives
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material, a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression.

Overview

Wood

                 Wood is the main constituent of many sheet goods. Some of these may be used in the main structural components of a house; others for decorative finishings.


Types of Wood include

  • Plywood
  • MDF Board
  • Laminate
  • Veener
  • Particle
  • Blockboard

Classification of Wooden Materials

Plywood

is a sheet material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which includes medium-density fibreboard (MDF) and particle board (chipboard).


Medium-density fibreboard (MDF)

is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure. MDF is generally denser than plywood.


Laminate

Laminate is made with synthetic materials or very thinly sliced pieces of wood. In some cases, it is made to look like wood grain by using a method that is similar to printing. Laminate typically has a shiny finish and is known for being used in low-end furniture and pieces that need very durable surfaces.
Of course, laminate is much cheaper than solid wood or veneer to produce and use. At Furnish Green, we try to stay away from carrying many pieces with laminate, but occasionally find a server or console that we think looks great and fits the bill. Laminate pieces are incredibly easy to clean and maintain, great for children’s rooms or any spot where it will get a lot of wear. Although it is not real wood, laminate can be painted by sanding the piece lightly to remove the glossy finish, primed, and then painted with thin layers of your favorite color.


Veener

Veneer is technically a thin layer of hardwood, usually thinner than 1/8 of an inch. Typically, veneer is bonded, or glued with adhesive, to a cheaper surface that is hidden below. This practice allows furniture makers to design and build beautiful pieces at a lower cost.
At Furnish Green, we often find a lot of mid century pieces with dark walnut veneer and Danish modern pieces with teak veneer. Veneer can be sanded along the grain, painted and stained because it is real wood. When working with it though, you must be very careful not to overdo it, remembering that the layer is very thin and can quickly be worn down with a power sander.


Difference Between Wood

Difference between Plywood and MDF

Plywood MDF
Plywood is an engineered wood product that is made by pressing and binding sheets of wood veneer together into one solid piece. MDF is also an engineered wood composite that is similar to particle board, but is much denser and stronger than particle board.
Plywood is Expensive than MDF MDF is generally cheaper than plywood.
It’s less susceptible to water damage than MDF, and won’t soak up water and swell as quickly or easily as MDF does. The surface of MDF is very smooth, and can soak up water.

Difference between Veneer and Laminate

Veneer Laminate
Veneer is a very thin slice of wood obtained from a tree log. That is why, it is also known as wood veneers, since they are actually slices of wood. Laminates, also known as decorative laminates are artificially produced materials made from paper and plastic resins.
Veneers are costly Laminates are less expensive as compared to Veneers
Veneers are difficult to maintain. Laminates are easy to maintain.

Adhesive & Its Types

Adhesive

Adhesive is any substance applied to one surface, or both surfaces, of two separate items that binds them together and resists their separation.

Types of Adhesives

1. Resins : They are a type of polymer of synthetic origin. Resins can be thermosetting and thermostatic types of adhesive, which means that they can be either remolded at high temperatures or they cannot be remolded once the curing process is over.

2. Hot Melt : These adhesives allow the user to harden and soften them whenever they want, using cold or heat. Hot melt adhesives feature an excellent bonding quality and once heated can bond really fast to materials. One of the greatest advantages of the hot melt adhesives is that if the user makes any mistake during the construction, the adhesive can be easily rectified and used again.

3. Contact Spray : Contact spray allows the user to bond different items both temporarily and permanently. Spray adhesive can be used on uneven and porous surfaces, and is waterproof and transparent. Contact sprays are flexible and do not stain. They are considered friendly to the environment because they do not contain any chlorinated ingredients.

4. Acrylic : The acrylic adhesives require some time to set and dry, opposite from other types of adhesives. Acrylic adhesives use a radical mechanism that consists of 2 individual components that mix together, creating the bonding feature. You can find acrylic adhesives in 2 different types, the solvent and emulsion ones, which are both used in construction.
