7 CRITERIA – TO HELP YOU FIND WHAT YOU NEED.

Knauf Perfect Surfaces products meet a wide range of quality and processing requirements. Our 7 criteria will help you find exactly the right Knauf Perfect Surfaces product for your project.

Easy to apply:
With a product that is easy to apply you will achieve high-quality results easier and faster.

difficult easy

Easy to sand:
Describes the sanding effort required to achieve the desired final result. A product that is easier to sand requires less effort to achieve a smooth final surface.

difficult easy

Quality of finished surface:
Describes the readiness of the finished surface after sanding for painting and/or final finishing. A high quality of finished surface means a smooth, consistent, and even surface finish without patches or stains.

rough smooth

Working time:
The amount of time you have to manipulate the product to the desired result on the wall. Longer working time gives you more time to get to a perfect finish.

short long

Layer thickness:
The recommended or optimal thickness of the material applied to achieve the best result.

1mm 5mm

Resistance to cracking:
The ability of the finish to withstand cracking at a given thickness. A better resistance to cracking means a stronger finish that will not crack easily.

low high

Resistance to shrinkage:
The resistance of the product to volume reduction caused by water evaporation. A higher resistance to shrinkage saves you time and material by eliminating the need for repeated application of material.

low high

SURFACE QUALITY SIMULATOR

Check surface qualities in practical application

As a builder/owner or as a practitioner you should know how the various surface qualities perform in the space after the construction project is completed – as a matter of fact, under any conditions. The differences between the specific levels of quality are not always clear at first glance, which makes selecting the right surface quality even more difficult. This is especially true if the wall was painted after plastering.
With this tool, you can test the performance of quality levels 1 through 4 in the room under realistic conditions such as changing daylight or artificial light. Pay particular attention to shadow formation and the visibility of joints.

The gypsum board surface quality standards

Q1	Q2	Q3	Q4
Suitable for: Surfaces to which the tile and the plate decoration or thick rendering layer will be used	Suitable for: For medium and rough structural wall decoration For dripping and structured painting/coating For decoration rendering with graininess > 1mm Deviations - in particular in lateral light - cannot be excluded	Suitable for: For medium and roughly fine structural wall decoration For frosted and non-structured painting/coating For decoration rendering with graininess < 1mm Deviations - in particular in lateral light - cannot be excluded	Suitable for: For smooth or structured wall decoration, for example, the glow Metalized or vinyl wallpaper For transparent coverage or painting/coating with moderate gloss For Stuccolustro or other high-quality smooth technique If the light characteristics (e.g. lateral lighting) can affect the finished surface optics, further undesirable effects (e.g. shading, minimum markings) are prevented
For surfaces that have no optical (ornamental) requirements	Conventional optical wall and ceiling surface requirements	For increased optical surface requirements	For high optical requirements
Usage Joint filling Coating visible fasteners	Usage Quality level (Q1) Additional coat, until degree-free transition to the plate surface is attained	Usage Quality level (Q2) Wide lay over the joint as well as sharp residue removal from cardboard surface in order to fill the pores with compound	Usage Quality level (Q3) For surface finishing in at least 1mm thick lay
