Directly from these types of surfaces do not recommend wrapping done. These surfaces have a rough plaster truncated surface to St. John in mastara. In this way, and achieved a smooth surface during bonding and is smooth surface when heat insulation wall plugging should be plates will occur on crashes and then surface irregularities that can occur. To be held on applications made of aerated concrete aerated concrete anchor, briquettes and brick made on this type of application is surfaces produced especially for the use of anchors is required.
