The most important things first
Spritzputz is usually converted to Glattputz during a renovation or refurbishment. The decisive factors are a clean, dry substrate, enough lead time for organization, and a realistic assessment of the effort. In practice, the effort mainly depends on the area, the covering effort, and the accessibility of walls and ceilings. For areas starting at 20 m2, engaging a professional is usually advisable.
Many expect that the actual plastering determines the effort. In the practice of Glanzmann & Stocker AG, something else is often decisive: how many square meters must be worked on, how extensive the covering is, and whether ceilings and wall surfaces are well accessible. These exact points are missing on many websites, but are crucial for homeowners when planning time, dust and workflow realistically.
What prerequisites must be met before the smooth plastering?
Before the work starts, the offer must be confirmed. Equally important is the substrate: The walls must be sanded and dry. For beginners, this means concretely: The existing surface must not have loose spots or residual moisture, otherwise the new buildup will not adhere properly.
From my experience, this preparation is exactly the point homeowners most often underestimate. Those who only look at the visible final surface quickly overlook that Glattputz is only as good as the base underneath. At Glanzmann & Stocker AG we regularly see that the problem is not the plaster material, but an inadequately prepared substrate.
How does the conversion from Spritzputz to Glattputz proceed?
- Obtain a quote
- Conduct on-site inspection
- Carry out the work
- Plan and wait for drying time
- Apply final coat of paint
Preparation also includes clarifying the substrate, clearing the rooms, and careful covering. Then the necessary layers for Glattputz are built up. Finally, quality requirements and the surface are defined, for example via the desired Q-level and the eventual color.
| Factor | Why it is important | What this means for you |
|---|---|---|
| Square meters of the area | More area means more preparation, more material and more work time | Not just one wall, but the entire affected area must be considered |
| Covering effort | Furniture, floors, doors and connections must be protected | The fuller the room, the longer the preparation |
| Accessibility of walls and ceilings | Hard-to-reach spots slow down the work | High ceilings and ceiling areas significantly increase the effort |
What mistakes have the biggest consequences with Spritzputz and Glattputz?
The most common misconception: conversion requires only a short period of work. Realistically, plan about 3 weeks of lead time for organization. If you don’t allow this buffer, coordination with trades, room preparation and drying quickly become urgent.
A second mistake is DIY work on an inadequately prepared substrate. If the area is not properly cleaned, sanded and dried before handover, follow-up damage can occur. In practice, mold is one of the risks if moisture or poor preparation remains in the structure.
When is DIY sufficient, when is a pro needed?
In not every case is a plasterer required immediately. If the area is small and the prerequisites are clean, preparatory tasks like clearing or covering can be done by oneself. However, once it comes to the actual building of an even Glattputz surface, the requirements quickly increase.
What we repeatedly notice: the boundary is less about motivation than area and the uniformity expected in the end. From 20 m2, Glanzmann & Stocker AG recommends engaging a plasterer. This is especially true for ceilings, hard-to-reach areas, or when a clean finish without visible transitions is desired.
Checklist before start
Confirm the offer, check the substrate, sand the walls, ensure dryness, clear the rooms, plan protective coverings, reserve drying time, and specify the desired final color.

If you want to convert Spritzputz to Glattputz, you should not only focus on the visible final result but especially on preparation and workflow.
