A drier absorbs oxygen from air and transfer it to linseed oil, which in turn, gets hardened. They may be eir in form of soluble driers or paste driers.

Hint Answer

2. The ___________ are liquid substances which hold ingredients of a paint in liquid suspension.

Drier Base Solvent Vehicle

Hint Answer

3. ______________________ essentially consist of oil and stronger drier.

Asbestos paint Cellulose paint Cement paint Anti-corrosive paint

Anti-corrosive paint

A pigment such as chromium oxide or lead or red lead or zinc chrome is taken and after mixing it with some quantity of very fine sand, it is added to anti corrosive paint. The advantages of anti corrosive paint are: it is cheap and it last for long duration.

Hint Answer

4. While preparing whitewash, up to how many grams of ultra-marine blue is added per kg of lime?

3 gm 30 gm 200 gm 300 gm

3 gm

While preparing whitewash, up to three grams of ultra-marine blue is added per kg of lime. It is usually added to last two coats of solution. Ultra-marine blue is a blue colored pigment of sodium aluminosilicate containing sulphur.

Hint Answer

5. On drying, film of distemper _______

Swells Disappears Shrinks Thickens

Shrinks

The distemper possesses property of shrinkage on drying. Hence it leads to cracking and flaking, if surface to receive distemper is weak. The coating of distemper are usually thick and y are more brittle than or types of water paints.

Hint Answer

6. __________________ are specially adapted for exposed works which require frequent cleaning.

Oil Varnish Spirit Varnish Water Varnish Turpentine Varnish

Oil Varnish

The linseed oil is used as a solvent in oil vanishes. The hard resins such as Amber and Copal are dissolved in linseed oil and if Varnish is not workable, a small quantity of turpentine is added. The oil vanishes dry slowly, but y form hard and durable surface for cleaning.

Hint Answer

7. ___________________ defects is caused by water vapour which is trapped behind painted surface.

Flaking Fading Blistering Flashing

Blistering

In Blistering, re is formation of bubbles under film of paint. It may occur from various causes such as in perfect seasoning of timber, excess oil used in final coat, etc.

Hint Answer

8. The formation of soap patches on painted surface is termed as _______

Wrinkling Running Sagging Saponification

Saponification

Saponification is due to chemical action of alkaline. When a horizontal surface is too thickly painted , defect of Wrinkling becomes prominent.

Hint Answer

9. _____________________ forms base of all iron Paints.

Titanium white Zinc white Antimony white Iron oxide

Iron oxide

The tint of paint varies from yellowish brown to black. It mixes easily with vehicle. It is effective in preventing rusting of iron surfaces. It is cheap and durable. It is generally used for priming coat of iron surfaces.

Hint Answer

10. The sulphate of _____________ is used with zinc paint so as to eliminate risk of discoloration of a lead drier.

Manganese Magnesium Potassium Calcium

Manganese

It is required to take extreme care in mixing sulphate of Manganese. Orwise, spots will be formed on painted surfaces.
