Q3

Class Q3 by DIN 18550 + Visual Flatness

DIN 18202 (Tab. 3, Gr. 6)
up to 1.0 – 2.0 mm / 2m

Optimal balance for living spaces with ultra-matte paint under standard lighting. Eliminates overpaying for excessive polishing while ensuring a monolithic look.

Building Tolerances & Inspection Rules:
Parameter Standard Value What it Means in Practice
Plane Tolerance DIN 18202 (1.0 – 2.0 мм) Gap under 2m straightedge. Skirtings and trims fit without gaps.
Corner Geometry DIN 18202 (Winkel 90°) Even plane or strict 90° in furniture abutting zones.
Light Inspection DIN V 18550 Inspection under diffuse light without glancing beam at 5 cm.

Class Q3 under diffuse light: seamless flat plane
Under regular lighting micro-pores remain hidden, ultra-matte paint leaves no glare.
1 Trowel marks
2 Drywall joint shadow
3 P120 scratch marks
4 Micro-pores and craters
Physics of Grazing Light: When light strikes at a 5–10° angle (floating ceilings, wall sconces, Lossew lamp), even a 0.3 mm micro-flaw casts a contrast shadow up to 8–10 mm long. For such areas, DIN 18550 strictly prescribes continuous polymer paste and premium Q4 preparation.

3. Volumes, Budget Optimization & Extra Options

Area Input Mode:
Choose a convenient method: quick express calculation or exact wall dimensions

Window and Door Openings (Slopes)
Windows:
Window Parameters (1.4 × 1.5 м = 2.1 м²)
Doors:
Не вычитать площадь окон и дверей из общей площади стен при расчете малярных работ.
Дополнительные конструкции и декор
Подготовка и окрас коробов из гипсокартона с шириной стороны до 1000 мм по стандарту качества Q1–Q4.
пог.м
Включает грунтовку, установку защитных уголков, ленту для швов, шпатлевание и покраску в 2 слоя.
Монтаж молдингов, карнизов, розеток, консолей, пилястр и фронтонов.
Estimate Optimization Levers (What-If Scenarios)

You can adjust the budget without sacrificing quality by selecting alternative scenarios:

Substrate already prepared: scuff sanding for adhesion + local defect repair + 2 coats tinted paint (without full leveling and skimming). When optimized, the requirement class is reduced from Q4 to Q2 (standard requirements for secondary repainting).
Lowers class from Q4 to Q3 (saving 20–25% on putty and polishing).
Wallpaper texture conceals side daylight from panoramic windows, reducing preparation grade to Q2 (savings 25–30%).
Saves up to 35% of plaster and preserves usable living space on other walls.
