CEILING FINISHING

Made from lime,sand and serabut. Lime from limestone was burned to the

temperature of 9000 C to 12000 C. Lime that made from the first process is

called calcium oxide(quick line),which power

to absorb water strongly. Thus,this lime can not be directly used for

plaster work. It is easy to make and cheap.

How Does It Process??LIME PLASTER

LIME PLASTER

The raw material used is cement and sand. The cement used for this work is portland cement and

white cement is sometimes used for ornamental work. River sand used to make plaster ceiling must be smaller sized than the river sand used to make plaster

walls and plaster floors. Sand and water used for mortar must be clean and not

contained other materials and chemicals. For cement mortar,sometimes lime is added to

facilitate plastering work. The ratio of the mortar used to make plaster ceiling is

1:2.

CEMENT PLASTER

CEMENT PLASTER

This type of plaster are made from cement and lime.

It produced by grumbling using rough cast’,which a type of hand tool.

The surface is rough which suitable for the ceiling surface of the external side of the

building. In order to make this plaster,cement and

sand used was 1:4.

TYROLEAN PLASTER

TYROLEAN PLASTER

This plaster is made from a mixture of lime and gypsum.

It is found in layer form. This layer is usually huge in size which make it suitable for any ceiling situation.

It have good sound insulation and air proof but tend to broken or crack.

GIPSUM PLASTER

GIPSUM PLASTER

Ceiling finishes is made of wood strip size 12mmx25mm.

Most of the wood used is grade C wood which is arranged in a longitudinal ways.

The wood strips is arranged at a distance of 13mm depending on the situation.

This finishing usually used for verandah and external side.

WOOD STRIP

WOOD STRIP

Soft board is a piece of chips or other materials called “lignocellulose” that glued with a synthetic resin or organic adhesive.

This product also know as a chip board or board of flax(papan rami).

Softboard is manufactured in a pieces form(kepingan)of one layer or more.

One layer of board form have high density than board contains more layers.

SOFT BOARD

Its length is 1.8m,2.4m,2.7m and 3.0 and the width is 600mm,900mm and 1.2m Softboard is widely used in furniture

manufacturing such as cadinet, cupboard and speaker box.

In housing industry, softboard is used for ceiling, wall partition and panelling.

Softboard have high strength and weight ratio, dowel and screw characteristic, smooth surface and easily painted.

It can also changed a noise to a low frequency

Disadvantages of soft board is that it is easily absords moisture.

SOFT BOARD

Made from thin pieces of wood known as ‘vinir’.

Always used an odd number of layers and the number of layers is varies according to

thickness of plywood sheets to be produced. Each layer may consist of one or two

‘vinir’.These layers is glued to each other.

PLYWOOD

The opposite direction of the grain givens a high strength of plywood .(Arah ira yang bertentangan memberikan papan lapis

kekutan yang tinggi). Types of wood used to make plywood is lime,

keruing, mengkulang, meranti and mersawa. Other forign wood species used for making

plywood are doughlas fir from canada and brich from finland

These are TWO types of plywood which are external types and interior types.

These types of plywood is based on the moisture resistance which are external plywood is more good

moisture resistanse compared to the internal plywood.

EXTERNAL PLYWOODAre made from high grade timber and glued with waterproof glue.

INTERNAL PLYWOODIs suitable used for moisture content not more than 18% and the

structure that not exposed to the weather, otherwise EXTERNAL PLYWOOD will be used.
