Difficulty: Easy
Correct Answer: All of the above
Explanation:
Introduction / Context:
Every coating system has compatible thinners that adjust viscosity and drying characteristics. This question checks practical knowledge of typical thinners used with common paint categories in building works.
Given Data / Assumptions:
Concept / Approach:
Correct thinning ensures proper atomization, leveling, and film formation. The usual pairings are: alcohols for many lacquers, esters/ketones like ethyl acetate for cellulose paints, petroleum distillates (e.g., mineral spirits/naphtha) for oil paints, and plain water for distemper (a water-based paint).
Step-by-Step Solution:
Verification / Alternative check:
Manufacturer data sheets and trade practice guides confirm these pairings as standard recommendations for application and cleanup.
Why Other Options Are Wrong:
Each single statement captures only one pairing; the comprehensive, correct grouping is the “All of the above” choice.
Common Pitfalls:
Using an incompatible thinner can cause poor film formation, slow drying, or surface defects like orange peel and pinholing.
Final Answer:
All of the above
