1What is the primary chemical and physical distinction between a Calcium Sulfate screed (Calciumsulfatestrich CA/CAF) and a Cement screed (Zementestrich CT) regarding its behavior when exposed to moisture?

A.Calcium sulfate screeds lose significant mechanical strength and become water-soluble when wet, and they react with cementitious adhesives to form expansive ettringite if not isolated by a barrier primer.

B.Calcium sulfate screeds exhibit higher alkalinity (pH > 12) than cement screeds and undergo hydraulic curing that increases strength when continuously submerged in water.

C.Calcium sulfate screeds exhibit significantly higher thermal expansion coefficients than cement screeds and do not require movement joints even on heated floor assemblies.

D.Calcium sulfate screeds cure exclusively through carbonation from atmospheric carbon dioxide, making them completely impervious to water vapor and moisture damage.

Explanation: Calcium sulfate screeds (CA/CAF) use calcium sulfate hemihydrate or anhydrite as the binder (pH ~7). When re-wetted, the dihydrate matrix softens and loses compressive/tensile strength. Furthermore, when wet cementitious thin-bed mortar (containing calcium aluminates) comes into direct contact with calcium sulfate, it forms the expansive mineral ettringite (Treiberscheinung), causing catastrophic delamination. In contrast, cement screeds (CT) have a high alkaline pH (~12–13) and are hydraulically bound, retaining structural integrity when wet.

2When conducting a CM moisture test (Calcium-Carbid-Verfahren) on a cement screed (Zementestrich CT) to determine readiness for tiling (Belegreife), what is the correct test procedure?

A.Take a 50 g sample from the lower half to lower third of the screed cross-section, crush it in the CM cylinder with 4 steel balls, add the calcium carbide ampoule, seal the vessel, shake vigorously for 2 minutes, and read the manometer after 10–15 minutes.

B.Take a 10 g sample exclusively from the top 5 mm surface skin, crush it with an electronic blender, add water, and read the manometer immediately after 30 seconds.

C.Take a 100 g sample from the perimeter insulation strip, shake for 30 minutes without steel balls, and record the highest momentary peak pressure.

D.Take an uncrushed core drill sample of 200 g, insert it directly into the CM bottle with dry ice, and measure the temperature drop after 60 minutes.

Explanation: According to Austrian standard test guidelines and ÖNORM B 3407 / ÖNORM B 2232, a representative 50 g sample of cement screed must be taken across the lower half to lower third of the screed layer (where moisture remains longest). The material is weighed, placed in the steel cylinder with 4 steel balls and an intact calcium carbide ampoule, sealed, shaken vigorously to break the ampoule and pulverize the screed, and read after 10–15 minutes once the chemical pressure reaction (generating acetylene gas) has fully stabilized.

3According to ÖNORM B 3407, what are the maximum permissible residual moisture limits (Restfeuchte) determined by CM-Messung for unheated Cement screed (CT) and unheated Calcium sulfate screed (CA) before installing ceramic tiles?

A.Unheated Cement screed (CT) ≤ 2.0 CM-%; Unheated Calcium sulfate screed (CA) ≤ 0.5 CM-%

B.Unheated Cement screed (CT) ≤ 3.5 CM-%; Unheated Calcium sulfate screed (CA) ≤ 1.5 CM-%

C.Unheated Cement screed (CT) ≤ 0.5 CM-%; Unheated Calcium sulfate screed (CA) ≤ 2.0 CM-%

D.Unheated Cement screed (CT) ≤ 1.0 CM-%; Unheated Calcium sulfate screed (CA) ≤ 1.0 CM-%

Explanation: Under ÖNORM B 3407 (Planung und Ausführung von Fliesen-, Platten- und Mosaiklegearbeiten) and Austrian trade guidelines, an unheated cementitious screed (CT) reaches readiness for ceramic tiling (Belegreife) at a maximum residual moisture of ≤ 2.0 CM-%. An unheated calcium sulfate screed (CA/CAF) must not exceed ≤ 0.5 CM-% residual moisture to prevent ettringite formation and structural softening under the impervious tile covering.

4When installing ceramic floor tiles on heated screeds (beheizte Estriche mit Fußbodenheizung), what are the maximum permissible CM residual moisture values required by ÖNORM B 3407?

A.Heated Cement screed (CT) ≤ 1.8 CM-%; Heated Calcium sulfate screed (CAF) ≤ 0.3 CM-%

B.Heated Cement screed (CT) ≤ 2.5 CM-%; Heated Calcium sulfate screed (CAF) ≤ 1.0 CM-%

C.Heated Cement screed (CT) ≤ 0.3 CM-%; Heated Calcium sulfate screed (CAF) ≤ 1.8 CM-%

D.Heated Cement screed (CT) ≤ 2.0 CM-%; Heated Calcium sulfate screed (CAF) ≤ 0.5 CM-%

Explanation: For floor screeds incorporating underfloor heating systems, higher thermal vapor pressures develop during operation. Therefore, ÖNORM B 3407 enforces stricter moisture limits: heated cement screeds (CT) must reach ≤ 1.8 CM-%, while heated calcium sulfate flowing screeds (CAF) must reach ≤ 0.3 CM-% residual moisture. In addition, an official heating protocol (Aufheizprotokoll) is mandatory.

5What is the standard minimum curing age of a conventional Portland cement screed (CT-C25-F4) before functional heating (Funktionsheizen) can be initiated?

A.At least 21 days after screed installation

B.At least 3 days after screed installation

C.At least 7 days after screed installation

D.At least 60 days after screed installation

Explanation: Standard Portland cement screeds require a hydration curing period of at least 21 days before functional heating (Funktionsheizen) can commence (for calcium sulfate screeds, heating can typically start after 7 days). Complete hydraulic curing without heating takes at least 28 days under standard climatic conditions (20°C / 65% RH).

6According to ÖNORM B 2232 and ÖNORM B 3407, how must the commissioning heating procedure (Funktionsheizen und Belegreifheizen) for a heated cement screed be structured?

A.Start at a supply flow temperature of 25°C for 3 days, increase daily by 5°C up to maximum design flow temperature (max 55°C), hold for at least 4 days, then decrease daily by 5°C until reaching ambient temperature.

B.Turn the heating immediately to maximum flow temperature (70°C) for 24 hours, then turn off the boiler completely.

C.Maintain a constant flow temperature of 30°C for 30 consecutive days without any ramping or cooling phases.

D.Operate heating exclusively at night in 1-hour bursts at 80°C to induce thermal shock and relieve internal stresses.

Explanation: The standard heating protocol consists of two phases: functional heating (to test pipe expansion and release internal shrinkage stresses) and readiness heating (Belegreifheizen to expel free capillary water). It begins at 25°C (or approx. 5°C above ambient) for 3 days, ramps up in controlled 5°C daily increments to maximum design flow temperature (holding max design temperature for at least 4–11 days depending on screed thickness), and steps down by 5°C per day until cooled.

7What is the minimum surface tensile pull-off strength (Oberflächenzugfestigkeit / Abreißfestigkeit) required for a mineral floor screed prior to laying ceramic tiles in commercial high-traffic areas?

A.At least 1.0 N/mm² (or 1.5 N/mm² for high dynamic vehicle loads)

B.At least 0.1 N/mm²

C.At least 5.0 N/mm²

D.At least 10.0 N/mm²

Explanation: Under Austrian standards and technical guidelines for tile laying, the surface tensile strength of a screed substrate must be at least 1.0 N/mm² for standard commercial floor coverings and large formats (min. 0.5 N/mm² for standard domestic wall tiles). For areas subjected to heavy industrial traffic or forklifts, a tensile strength of ≥ 1.5 N/mm² is required to prevent adhesive shear failure within the upper screed boundary zone.

8Under DIN 18202 (Toleranzen im Hochbau) Table 3, what is the maximum permissible flatness deviation (Ebenheitstoleranz) for a floor screed receiving a thin-bed ceramic tile covering under standard requirements (Line 3) at a measuring point distance of 1 meter?

A.4 mm

B.1 mm

C.8 mm

D.12 mm

Explanation: According to DIN 18202 / ÖNORM DIN 18202 Table 3 Line 3 (standard requirements for finished surfaces of screeds receiving floor coverings such as tiles in thin-bed mortar), the maximum permissible gap under a 1 m straightedge (Messpunktabstand 1 m) is 4 mm (and 10 mm at 4 m). For elevated requirements (Line 4, e.g. for large format tiles), the limit is tightened to 2 mm at 1 m and 4 mm at 4 m.

9During substrate inspection, a tile master performs a scratch test (Gitterritzprüfung) and detects a brittle, powdery surface crust (Sinterschicht / Mehlkornschicht) on a calcium sulfate flowing screed (CAF). What is the mandatory remedial action before applying any primer or adhesive?

A.Mechanically grind the screed surface (Schleifen) to remove the weak laitance layer, followed by thorough industrial vacuum cleaning (Absaugen).

B.Apply three coats of deep penetrating oil to dissolve the crust chemically into the matrix.

C.Cover the sintering layer directly with plastic polyethylene sheeting and install tiles loosely without adhesive.

D.Wash the surface with high-pressure hydrochloric acid without mechanical grinding or vacuuming.

Explanation: A laitance or sintering layer (Sinterschicht) consists of binder-rich, weak fines and water that rise to the surface during screed bleeding and drying. It lacks structural cohesion and surface tensile strength. Under ÖNORM B 3407 and ÖNORM B 2207, the sintering layer must be mechanically abraded (by diamond/sandpaper grinding or shot-blasting) down to the solid aggregate matrix, followed by high-suction industrial vacuuming before primer application.

10What is the primary technical function of applying an acrylic dispersion primer (Dispersionsgrundierung) to an absorbent cementitious screed before applying tile adhesive?

A.It reduces and harmonizes substrate absorbency, binds residual dust particles, and prevents the substrate from prematurely drawing mixing water out of the tile mortar ('Verdursten').

B.It acts as a permanent structural vapor barrier that stops hydrostatic groundwater pressure.

C.It replaces the need for movement joints by absorbing all shear forces within its elastic film.

D.It chemically neutralizes all sulfate ions and transforms calcium carbonate into granite.

Explanation: An acrylic dispersion primer penetrates porous mineral substrates to bind microscopic dust, reduce suction, and equalize absorbency across the surface. This prevents the porous screed from rapidly sucking the mixing water out of the cementitious adhesive, which would otherwise starve the cement of water needed for hydration ('Verdursten des Mörtels') and lead to weak, powdery bond strength.

Meisterprüfung Platten- und Fliesenleger Study Tips from Top Performers

1Master the CM-Gerät moisture measurement protocol: ensure samples are taken from the lower half/third of the screed cross-section, crushed with steel balls, weighed accurately (50g for CT), and allowed to react for at least 10–15 minutes until the pressure gauge stabilizes.

2Memorize the moisture thresholds and heating protocols: know by heart that unheated CT requires <= 2.0 CM-%, heated CT <= 1.8 CM-%, unheated CA/CAF <= 0.5 CM-%, and heated CA/CAF <= 0.3 CM-%. Understand the daily +5°C temperature ramping cycle of Funktions- und Belegreifheizen.

3Understand adhesive and grout classifications under EN 12004 and EN 13888: distinguish C1 (>= 0.5 N/mm²) vs C2 (>= 1.0 N/mm²), S1 (2.5 to < 5 mm deformation) vs S2 (>= 5 mm deformation), T (slip resistant), E (extended open time >= 30 min), F (fast setting), and CG2 WA vs reaction resin RG.

4Know the movement joint rules under ÖNORM B 3407 and ÖNORM B 2207: interior unheated fields up to 40–60 m² (max 8 m side), interior heated fields up to 20–40 m² (max 6–8 m side, matching heating circuits), and outdoor balcony/terrace fields of max 4–9 m² (max 2.5–3.0 m side). Never bond joints across three flanks (use PE backing rods).

5Learn the legal and contract distinctions under ÖNORM B 2207 and § 1168a ABGB: clearly differentiate Nebenleistungen (included in unit prices) from Besondere Leistungen (separately billable, e.g. crack repair, leveling outside DIN 18202), and know the formal requirements for a written Bedenkenanmeldung (Warnpflicht).

6Practice calculation formulas: master tile waste percentage calculations (5–7% orthogonal, 10–15% diagonal), adhesive consumption (kg/m² per trowel notch size plus back-buttering), grout consumption formulas based on tile dimensions, and the calculation of the trade hourly rate (Kalkulatorischer Mittellohn).

Frequently Asked Questions

What is the Meisterprüfung Platten- und Fliesenleger in Austria?

The Meisterprüfung Platten- und Fliesenleger is the official statutory master craftsman qualifying examination in Austria for the tile, slab, and mosaic setting trade, established under § 94 Z 38 of the Austrian Trade Code (Gewerbeordnung 1994). Administered by the Meisterprüfungsstellen of the Austrian Economic Chambers (WKO), it is positioned at Level 6 of the National and European Qualifications Framework (NQR/EQF Level 6, equivalent to a Bachelor's degree). Passing the examination entitles the holder to use the legally protected title of 'Meister' (Mst.), manage an independent tiling contractor business, and train apprentices.

What are the 5 modules of the Austrian Fliesenleger Meisterprüfung?

The examination comprises 5 separate modules. Modul 1 is the practical examination (Teil A work sample at apprenticeship-final level, Teil B the multi-day Meisterstück project encompassing layout, substrate preparation, bonded waterproofing, and complex tiling). Modul 2 is the oral examination (Fachgespräch covering materials technology, planning, building physics, and standards before the commission). Modul 3 is the written theoretical examination across three subjects (Fachtechnologie, Planung und Technisches Zeichnen, and Fachkalkulation/Angewandte Mathematik). Modul 4 is the Ausbilderprüfung (trainer examination under the Berufsausbildungsgesetz), and Modul 5 is the Unternehmerprüfung (business management and legal examination). Candidates with a relevant Lehrabschlussprüfung are credited for Teil A of Modules 1 and 2.

What are the water exposure classes under ÖNORM B 3407?

ÖNORM B 3407 defines six water exposure classes for bonded waterproofing (Verbundabdichtung): W1 (very low exposure: dry rooms, living areas, guest toilets), W2 (low exposure: domestic kitchens, commercial dry WCs), W3 (moderate exposure: residential bathrooms with shower trays raised > 2 cm above floor, bathtub walls), W4 (high exposure: walk-in / floor-level showers, laundry rooms), W5 (very high exposure: commercial kitchens, industrial wet rooms, swimming pools), and W6 (outdoor weather exposure: balconies, terraces, loggias). Classes W3 through W6 require certified bonded waterproofing membranes, system sealing tapes, and pipe collars.

What are the CM moisture limits for screeds before tiling in Austria?

Under ÖNORM B 3407 and Austrian technical trade guidelines, moisture readiness (Belegreife) must be verified via the calcium carbide method (CM-Gerät): For cementitious screeds (Zementestrich CT), residual moisture must not exceed <= 2.0 CM-% for unheated screeds and <= 1.8 CM-% for heated screeds (Fußbodenheizung). For calcium sulfate screeds (Calciumsulfatestrich CA/CAF), residual moisture must not exceed <= 0.5 CM-% for unheated screeds and <= 0.3 CM-% for heated screeds. Heated screeds additionally require a documented commissioning heating protocol (Funktions- und Belegreifheizen) before tiling.
