Adhesive bonding technology is successfully applied partly in the primary production, partly in the renovation in various fields of human activities. This fact emphasizes the importance of the partial factors research, which influence is essential for the quality, reliability and necessarily the usable life of bonded joints. The mechanical preparation of bonded surface is a varied process which influences directly the resultant bonded joint quality. The aim of the bonded surface mechanical preparation is the adhesion improvement in the adhesive - adherend interface. For mechanical preparation we use tools of defined cutting edge, by means of which we get the uniform surface texture, e.g. by milling. On the contrary such methods are more often used when the uniform surface cannot be reached. Shot blasting and grinding are significant representatives of these methods. The manual grinding can be significantly applied mainly in the agriculture. The absence of connected areas availability for the mechanical tooling and impossibility of their work clamping are the reasons for that. The breakwater in the sprinkler cistern restricting the liquid motion is the example.
