Plastermap: Plaster Calculator

Plaster calculator for walls and ceilings, from your floor plan. Plastermap is a wall plastering calculator that tells you how much plaster to buy: bags of mix, screeds, corner beads, stop beads, mesh, primer and spatter coat — for every wall and for the whole project. Every number on screen is free, no sign-up. WHAT IT DOES • Recognizes a floor plan from a photo — a drawing, a plan from your documents or a sketch with dimensions • Layer thickness from laser readings or as one number, with a thickness map of each wall • Gypsum, lime-cement and cement plaster coverage — in kilograms and bags • Screeds with distances from the corner, beads at openings, mesh and reveals • Shopping list for the whole project and a PDF report A PLAN IN A MINUTE Photograph the plan — Plastermap finds the rooms, walls, doors and windows. A whole floor or a single room; the first room is free. Or draw a room by hand: rectangle, L-shape or wall by wall, with partitions, columns and boxing. Sizes are masonry sizes, as on the plan: plaster is calculated from the bare walls. HOW MUCH PLASTER DO I NEED By default the layer is 15 mm on every wall. For more accuracy, set a laser line and enter the distance to the wall at a few points. The app finds the most protruding spot and shows where the layer is thin and where it is thick. Coverage: gypsum 1.0, lime-cement 1.3, cement 1.7 kg/m² per mm, plus a 5% reserve, in whole bags. For your product, enter the rate from its data sheet. SCREEDS AND BEADS 6 mm screeds spaced for your straightedge, with distances from the left corner for marking out. At openings a screed continues the corner bead; none in the middle of an opening. Corner beads on reveal edges, stop beads at frames — in whole 3 m lengths. Over 25 mm the app suggests two coats and mesh. TOTALS AND REPORT Wall area up to 3 m and above, reveals, narrow strips, layer volume, bags, primer, bonding primer, spatter coat, screeds, beads, mesh. A PDF report with wall elevations, thickness maps and screeds — for you, your plasterer or the store. FREE AND PAID Plans, the calculation and every number on screen are free. The PDF report and project file come with a project purchase (one-off, valid in all Nearfolk apps) or a yearly Plastermap Pro subscription. WORKS WITH OTHER NEARFOLK APPS One plan for plastering, tiles (Seamline), floors (Plankmap) and ceilings (Ceilmap). Projects move between the apps with one tap. Plans stay on your phone; back up all projects in one file. Built-in help with FAQ, eight languages, light and dark theme. KNOWN LIMITATIONS Decorative plaster and skim coats are not calculated. Thickness between readings is interpolated — more points, more accurate volume. Results are estimates: check sizes on site and coverage against the bag. Questions and suggestions: [email protected]
