SURFACE(WALL) FINISHING

SUBMITTED TO: AR. SAURABH SAXENA SUBMITTED BY: SACHIN KUMAR PATEL B.ARCH 2 ND YEAR 3 RD SEM 201811101010002



Finish given to the wall to enhance the exterior look of the

structure.

 Surfaces may be smooth or textured and better wall

finishes are durable.

 Some wall finishes are versatile, taking decorative finishes

such as stain, paint or wallpaper readily.



Walls may make a decorating statement, or may be simply

background.

 Concrete, masonry wall may be left exposed or plastered.



Wood or metal stud walls can support a variety of finishes.

INTRODUCTION

 (^) It should adhere to the background, and should remain adhered during all variations in seasons and other atmospheric conditions.  (^) It should be hard and durable.  (^) It should possess good workability.  (^) It should be possible to apply it during all weather conditions.  (^) It should be cost efficient.  (^) It should be cheap and economical. REQUIREMENTS OF GOOD PLASTER

Smooth Cast Plaster Finish

o To obtain smooth cast finish, mortar

used should be in the ratio 1: 3

[cement: sand]. Fine Sand should

be taken to prepare the mortar. For

spreading the mortar, skimming

float or wood float is best suitable

tool. Hence, smooth and levelled

surface is obtained finally.

DIFFERENT TYPES OF WALL FINISHES

 (^) Sand Faced Plaster Finish  (^) To get sand faced finish two coats of plastering is required. For first coat, 12mm thick layer of cement sand mortar in 1: 4 ratio is preferred. The first coat should be provided in zigzag lines. And then it is allowed for curing for 7days.  (^) After that 8mm thick layer of second coat with cement and sand in 1:1 ratio is applied. Level the surface using sponge. Finally take some sand and screened it to obtain uniform grain size. The screened sand is applied on the second coat using skimming float or wooden float. Finally, sand faced finish with uniform grain size of sand is obtained. DIFFERENT TYPES OF WALL FINISHES

Stained Glass Finish

It involves lot of creative work. The glass is decorated with

itching, frosting, glass pasting and finally colouring with

suitable colours according to the theme. The stained glass

panels are used on walls and ceilings.

DIFFERENT TYPES OF WALL FINISHES

Wood Panelling  (^) It is a decorative treatment done with wooden panels on the walls in various designs. The material used can be plywood or wood covered with veneer or laminate. DIFFERENT TYPES OF WALL FINISHES

 Tile Cladding

 (^) Different tiles, for example, granite, marble, glazed tiles or vitrified tiles are used for tile cladding. Tiles are available in a variety of colours and shapes. The selection of tiles depends on the place where it is to be applied i.e. interior facade or exterior facade. DIFFERENT TYPES OF WALL FINISHES

 Method Of Cement Plastering: o (^) You’ll find readymade cement plaster bag on the market. Readymade cement plaster is found on dry condition. You just need to mix water to that dry powder to prepare plastering paste. While mixing water, follow the specification provided by the manufacturer. o (^) You can also prepare cement plaster on site by mixing cement and sand. In fact most of the time we use manually mixing mortar. o (^) While mixing cement and sand, we use the ratio of 1:3 or 1:4 depending on the purpose of plastering. When we say 1:4 , we mean that one unit cement will be mixed with four units of sand. o (^) After mixing the cement and sand in the dry state properly, the required quantity of water is added to the mix. o (^) After mixing water it is then applied to the surface. o (^) The thickness of cement plaster varies depending on the surface condition. It can be 12mm to 25mm. It is normally applied in one coat. TYPES OF PLASTERS BASED ON MATERIAL USED

Lime Plaster  (^) Lime mixture consists of sand and line that are mixed by 1 sand to 3 of lime by volume. Not only this mixture is used for under coat but also used as finish coat. Lime plaster might be shrink after drying so animal hair of about 5 Kg is used for 1 m^2 to avoid lime plaster cracking and shrinking. Lime plaster could be used for ancient structure restoration and rehabilitation.  (^) Methods Of Lime Plastering  (^) The method of lime plastering is similar to the method of cement plastering. TYPES OF PLASTERS BASED ON MATERIAL USED

Gypsum Plaster  (^) Gypsum plaster is widely used plaster materials that could be mined naturally or produced as a by-product. So, important gypsum plaster that is employed as under coat, finish coat, and replaced lime and cement broadly.  (^) Moreover, small expansion of gypsum is considered significant propertied that prevent shrinkages and cracks.  (^) There are various types of gypsum plaster that are produced by heating gypsum to a specific degree for example anhydrous gypsum manufactured by heating gypsum up to 170 C o , hemihydrates gypsum produced by heating gypsum more than 170 C o .  (^) Furthermore, depending on applications for walls or ceilings gypsum plasters can be categorized such as casting, undercoat, finish, one coat and machine applied plaster. TYPES OF PLASTERS BASED ON MATERIAL USED

 Method Of Gypsum Plastering:  (^) You need to add water with the ready mix powder.  (^) The method of gypsum plaster is same as the cement plaster.  (^) The recommended thickness of gypsum plaster is 6mm to 12mm. TYPES OF PLASTERS BASED ON MATERIAL USED

Method Of Clay Plastering: o (^) To prepare the plaster paste, clay and sand are mixed in dry state and then water is added to the mix. o (^) The surface preparation for clay plastering is same as the cement plastering. o (^) The clay plaster is normally applied in two coats. The thickness of the 1st coat is about 18mm while the 2nd coat is 6mm. TYPES OF PLASTERS BASED ON MATERIAL USED Preparation clay plaster

Pointing is raking out joints in brick work or in stone masonry to depth about 13mm and filling the same with mortar of slightly richer mix.  PURPOSE o (^) This treatment not only protects the joints from the adverse effects of atmosphere but also magnifies the appearance of the surface by exhibiting the pattern of joints, their thickness, colours and textures prominently.
