A paste filled suction cup allows a platform to hold objects onto non-smooth surfaces. Laser levels and other devices can be affixed to this platform so that they can be quickly and easily placed on a wall. The action of the paste in the suction cup allows the suction cup to provide a temporary bond to the surface. The use of a water-soluble paste makes it easy to clean the wall after removing the suction cup. The paste also lets the platform be positioned by keeping it in the pasted area.
