For assembly of Heavy Kits in ETICS/EWIS to 16 cm insulation thickness with masonry, soft natural stone and similar materials. Conditionally suitable for concrete without reinforcement...pre-drilling with a smaller diameter is then recommended. In hollow bricks, aerated (cellular) concrete, and possibly even in normal 'bricks' -- drill without percussion. Not for wood. Cleaning holes with a hole brush and blower allows for higher adhesive forces and is essential for professional bonds with composite mortar.
