Avant / Après : La Magie d'Une Corniche De Plafond Bien Posée ! 💪

Since the room has interior (inner) and exterior (outer) corners, this will be an opportunity to see how to measure the dimensions, how to make the cuts without making a mistake, and, most importantly, how to install them, all by yourself. 🛍️ The Coach's Shop (tools and personalized advice): https://www.coachpersodeco.fr ▶️ Instagram:   / coachpersodeco   ▶️ TikTok:   / coachpersodeco   📖 CHAPTERS: 00:00 Trimming the Ceiling 02:47 Preparing the Cornices (Measuring and Cutting) for the Internal Corners 10:44 Installing the Cornices in the Internal Corner 14:05 Installing the Cornices in a Protruding Corner (Measuring, Cutting, and Installing) 18:04 Shaping the Cornices to Perfect the Finish 21:11 The Work is Complete! 🛠 MATERIALS USED: 8 cm drywall knife: https://coachpersodeco.fr/produit/cou...
