Introduction Drainage stucco is a cladding system designed to let water that gets behind the finish drain out, while barrier stucco is meant to shed water at the surface and keep moisture out; that’s the practical difference. Think of drainage as a layered system with a gap or channels to manage moisture and barrier as […]

Introduction Stucco clearance over walkways means keeping the bottom edge of an EIFS or stucco finish high enough and detailed so moisture doesn’t wick into the walking surface; in plain terms, it’s about creating a gap and proper flashing so water drains away instead of soaking the path. For DIYers that can mean trimming finish,

Introduction Stucco termination at brick or stone is the method of finishing and sealing the edge where stucco meets masonry so water is kept out and movement doesn’t crack the finish. Do the job with a clear gap for flashing, a solid backstop, and a termination trim that lets water drain; check product labels and

Introduction Plaster delamination “bubbles” are areas where the top plaster coat has lost adhesion to the substrate and forms a raised blister that can pop or tear back. This usually means moisture, weak bonding, or movement has separated layers; check the surface and product instructions to confirm causes before you act. In many cases you

Introduction Salts in masonry plaster are soluble minerals that migrate to the surface as moisture moves through the wall, leaving white or powdery deposits called efflorescence and in worse cases causing spalling where the plaster flakes or crumbles. This usually comes from water intrusion, damp soils, or moisture wicking through masonry and carries salts via

Introduction Plaster over blueboard means applying a veneer plaster finish bonded to the paper-faced gypsum board rather than feathering multiple coats of joint compound; it’s a different material and technique used when a harder, smoother surface is wanted. Veneer plaster generally requires cleaner, keyed surfaces and different tools than joint compound, so check product instructions

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 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
