3. The process of roughening the background is called as __________
a) Hacking
b) Plastering
c) Painting
d) Damping
View Answer

4. The thin layer of cement particles formed on excessive troweling is called ________
a) Undercoat
b) Peel
c) Laitance
d) Latch
View Answer
Explanation: The thin layer of cement particles formed on excessive troweling of freshly laid mortar is called laitance. This layer consists of fine cement particles.
5. Undercoat is the first coat of plaster applied.
a) True
b) False
View Answer
Explanation: Undercoat is the coat of plaster applied under the setting coat. The setting coat is the final coat of plaster which is also known as the finishing coat.
6. Formation of white crystalline substance which appears on the surface due to the presence of salts in materials used for making plaster is called as __________
a) Cracking
b) Crystallisation
c) Efflorescence
d) Crazing
View Answer
Explanation: Formation of white crystalline substance that appears on the surface due to the presence of salts in materials used for making plaster is called efflorescence. It results in a very poor and unpleasing appearance. It can be removed by washing the surface repeatedly.
7. Dislodgement of plaster from the background is called as ________
a) Peeling
b) Plastering
c) Distempering
d) Grinning
View Answer
Explanation: Dislodgement of plaster from the background is called peeling. Peeling involves the complete dislocation of some part of the plastered surface which results in the formation of a patch.
8. Popping is the formation of a _________ hole in the plastered surface.
a) Circular
b) Conical
c) Cylindrical
d) Rectangular
View Answer
Explanation: Popping is the formation of a conical hole in the plastered surface. It is due to the presence of some particles which on setting result in expansion.
9. Martin’s cement plaster is obtained when __________ is calcined with POP.
a) Pearl ash
b) Alum
c) Borax
d) Borane
View Answer
Explanation: Martin’s cement plaster is obtained when pearl ash is calcined with POP. It has quick setting properties and is used in internal finishing works.
10. Parian cement plaster is obtained when ________ is calcined with POP.
a) Pearl ash
b) Alum
c) Borax
d) Petroleum
View Answer
