Room-Specific Paint Recommendations
The wall area calculation is the same for all rooms: 2 × (Length + Width) × Height. Paint Volume = (Wall Area × Coats) ÷ Coverage Rate (400 sq ft/gal or 10 sq m/litre). What changes is the paint type recommendation: Kitchens should use satin or semi-gloss moisture-resistant paint (washable, resists grease). Bathrooms need mould-resistant paint with anti-fungal properties (satin or semi-gloss). Bedrooms can use standard matt or eggshell emulsion. Living rooms suit matt or satin finishes depending on traffic.
Frequently Asked Questions
What type of paint should I use in a kitchen?
Use a moisture-resistant, washable paint with a satin or semi-gloss finish in kitchens. These finishes resist grease stains, withstand steam, and can be wiped clean frequently. Semi-gloss is ideal for cabinets and trim, while satin works well on walls.
Do bathrooms need special paint?
Yes. Bathrooms require mould-resistant paint designed for high-humidity environments. Look for paint with anti-fungal additives. Satin or semi-gloss finishes are best because they resist moisture and are easy to clean. Avoid matt finishes in bathrooms as they trap moisture.
