Introduction Casein paint is a milk-protein–based paint and lime plaster is a breathable, alkaline render; used together they can work but only with the right prep because lime’s high alkalinity and porosity can make paints fail. In plain terms: casein can bond to lime if the plaster is clean, stable, and its surface chemistry is […]

Introduction Plastering over old calcimine paint means confirming the paint is the flaky, powdery lime-based finish that repels new plaster and then removing or treating it so plaster can bond. I’ll show simple tests to identify calcimine and practical fixes for adhesion problems you can do with common tools. If a product or spec matters,

Introduction Plaster feather edges that don’t flake are thin finish edges keyed and bonded to the existing surface, wetted and timed correctly so the new plaster grabs without lifting. Check whether the area needs repair by tapping or scraping loose material and by checking for movement; if substrate is dusty, crumbling, or contaminated you must

Introduction Getting dead-flat plaster walls means using straightedge checks and a stepwise build-up of layers until any high or low spots are leveled out. It’s a practical process of finding the worst deviations, feathering in material, and rechecking with a straightedge until the surface reads flat to the eye and tool. Expect to use joint

Introduction Repairing polished plaster chips means filling and feathering the damaged area so the patch matches surrounding sheen and texture without a visible ring. Start by cleaning and undercutting loose edges, use compatible repair material, and build thin layers that are troweled and polished to blend into the existing finish. Check product labels and manufacturer

Introduction Venetian plaster over existing textured walls means deciding whether to skim, sand, or remove that texture so the final finish looks smooth and bonds properly. In plain jobsite terms: skim if the texture is shallow and solid, sand if it’s flaky or slightly high, and remove if it’s loose, highly uneven, or has adhesion

Introduction Venetian plaster burnishing is the final rubbing of a polished plaster surface to compact and shine it using the right tools at the right moment. Pick flexible trowels or burnishers suited to your plaster type and check the product label for recommended tools, and make sure the base coat is dry and sound before
