Answer :
plywood :
1.General Projects. Due to its versatility, plywood is great for many other home projects from building skateboard ramps, to rabbit hutches to doghouses. Home DIYers love plywood as it is ideal for building useful items including workbenches, sawhorses, simple step-stools and storage bins.
2. Interior Walls
Certain types of plywood are good for wood paneling or framing interior stud walls.
In most cases, the plywood will not be visible for the final finish however, some highly finished A-graded plywoods are very good for facing inwards and can painted or stained to give a stunning natural wood finish.
3. Roofing and Flooring
Plywood is commonly used to sheath roofs and as a subfloor on many internal flooring projects.
On floors, plywood panels may include tongue-and-groove edges that slot together to allow them to carry the required load without shifting or movement whilst on roofs, they can act as a very durable and suitable skin prior to laying tiles, metal or a membrane.
Plywood is excellent for both applications.
4. Cabinets
Plywood is great for making cabinet carcasses for kitchens, bedrooms and more.
A good quality plywood is more than suitable for use on backs and sides of cabinets in most cases and is a far superior material to traditional chipboard or MDF as it lasts longer, doesn’t split and is far more durable.
chipboard :
1. Prepare the chipboard
Chipboard won’t take on your paint coverage unless it is completely clean, free of oily marks and dust particles. Wearing gloves, start by closely inspecting the surface of your chipboard and wipe away any oily marks with a cloth soaked in water and washing up liquid (make sure you wring it out so it’s just damp, so as not to soak your board). Loosely cover your board in protective sheeting to protect it from further dust and debris, and leave in an airy space to dry out completely for two days before you move on to the next step.
2. Sand the board down
Using a piece of medium-grit sandpaper (or an electric sander for large expanses of board), sand down the entire board to remove any surface imperfections. Sanding to a smooth surface finish will also help your sealant and paint stick to the board more easily. Once you’ve sanded the entire board, use a dry cloth to wipe it down and remove any remaining board particles.
3. Prime the chipboard
Priming your chipboard gives it a protective layer against moisture and dirt, while also creating a better surface for your paint to stick to. Start by placing your board on a protected surface in a well-ventilated space, and make sure you’re wearing gloves before you start, as you don’t want to get these substances on your skin.
Using a smooth paint roller, apply your primer in a thin, even layer and leave to dry completely as per the instructions on your chosen primer product. Repeat two or three times to build up several layers of primer, as these layers will stick to one another and provide a stronger, more protective barrier than you would get with just one layer.
hardwood :
The use of hardwood is much reduced in the modern world. The destruction of tropical and temperate forests has made it expensive and scarce. Many things once made of hardwood are now made of ceramics, plastic or softwood.
Hardwoods are often used to make items that get used a lot because of their density. These items include furniture, flooring, and utensils. They are also used in construction. Hardwoods are also less likely to decay or rot than softwoods. Furniture made by hardwood joinery is more expensive than that made from softwoods.
Utensils for use in preparing food can include things such as the vessel in the gallery below used by the Ede people to grind corn and grains for food. Other utensils include : spoons, chopsticks, bowls, plates and cups. Because of the dense nature of the wood used such a vessel can be used for many years without breaking. Other examples include the handle of the Luzon knife seen in the gallery.
