Estimation

Préparation (bâcher, scotcher) : 30-60 min. Peinture des murs : 15-20 m²/h au rouleau. Angles et finitions au pinceau : ajoutez 30-50%. Plafond : plus lent (20-30% de plus). Chambre de 12 m² (35 m² de murs) : ~4-6h total pour 2 couches incluant préparation et séchage entre couches.

Conseils

Investissez dans de bons outils : rouleau de qualité (5-10 €), scotch de masquage 3M (8-12 €). L'outil qui vous fait gagner le plus de temps : un bon scotch de masquage. Les lignes nettes sans scotch nécessitent une main experte.

⚡ CalcWolf Insight

Professional painters are 2-3x faster than DIYers but charge $1-3 per sq ft ($200-600 per room). The math: if painting takes you 8 hours and your time is worth $30/hour, the DIY cost is $240 in time + $50 in supplies = $290. A pro charges $300-500 for the same room. For one room, DIY saves a little. For a whole house, hiring a pro often makes more sense.
