Gaper - a tool for forming a shadow gap

CHANGE THE WAY YOU WORK 

WHAT IS GAPER?

Gaper is a specialized auxiliary tool designed to form an 
8 mm shadow gap joint when installing gypsum board ceilings. Its purpose is to save time, reduce labor costs, and ensure a perfectly straight shadow gap joint in every project.

With Gaper, you always achieve a professional, perfectly even shadow gap joint around the entire room – free of defects and irregularities.






WHY AN 8 MM SHADOW GAP JOINT?

8 mm is the standard that allows for a clean, professional shadow gap joint between the gypsum board and the wall.

  • This size is neither too small nor too large – it is ideal for finishing work: you can use either a finishing profile or silicone.
  • An 8 mm joint creates an aesthetic shadow effect and hides small irregularities.
  • It leaves enough space for finishers to complete the work with high quality.

    Most importantly, Gaper automatically forms a uniform 8 mm shadow gap joint, regardless of whether the installation is done with UD profiles or without them.
EASY TO USE AND REMOVE

Gaper makes it possible for one installer to complete the work – no need for an additional helper. This means lower costs, faster progress, and a simpler process.

5 TIMES FASTER WORK

With Gaper, the entire installation process becomes up to 5 times faster.

  • Ideally, use 4 Gapers per board to ensure an even shadow gap joint on all sides.
  • No extra measuring or adjustments – the result is automatically precise. 
ONE PERSON IS ENOUGH

Gaper makes it possible for one installer to complete the work – no need for an additional helper. This means lower costs, faster progress, and a simpler process.

MAGNETS FOR STABILITY

At the bottom, there are 5 strong magnets that ensure Gaper attaches firmly to the profiles. This guarantees stability and precision during installation.

FLEXIBLE FINISHING OPTIONS

Once the shadow gap joints are formed, finishing can be done according to your needs:

  • with a finishing profile – a PVC profile is inserted, filled, and a clean finish is achieved;
  • without a profile – the gap is filled with acrylic sealant, smoothed with a brush, and results in a clean, even shadow gap joint
DURABLE AND LONG-LASTING

Made of nylon, Gaper is extremely reliable:

  • it withstands drops of up to 3 meters,
  • has special cut-outs that absorb impact,
  • can be reused many times without losing functionality.
