h3webertherm 300 Adhesive and Reinforcement Mortar mineral-based universal 30 kgh3pbr Mineral-based universal adhesive and reinforcement mortar in the webertherm systems A 100, A 200, and B 100 Renovation mortar for coating load-bearing plasters br Application area br Thick-layer mineral-based adhesive and reinforcement mortar in the webertherm A 100, A 200, B 100, and AK 500BK 500 insulation composite systems Renovation mortar for coating load-bearing plasters br Product description br webertherm 300 is a factory-produced mineral dry mortar br Composition br Cement, white lime hydrate, classified mineral aggregates, fibers, hydrophobizing agent, additives for improved processing and adhesion to the plaster substrate br Product features br characterized by high adhesive strength and excellent processing properties, highly machine-pliable and also available as silo material. In combination with the webertherm reinforcement fabrics, a high-performance reinforcement layer is achieved. It can also be used for coating load-bearing plasters. br Color tones: gray br Application thickness: 5 mm – 8 mm br Water requirement: approx. 8 l per 30 kg br Storage br When stored in a dry, moisture-protected environment, the material remains storable for up to 1 year. br Substrate preparation br The substrate must be load-bearing, sufficiently dry, and even. The flatness of the substrate must meet the requirements of DIN 18 202 "Tolerances in Building Construction". br Dirt, dust, and loose parts must be removed from the substrate. br Existing old coatings must be removed to at least 70%. br For critical substrates, perform a adhesion test. br Processing br Processing steps br The adhesive and reinforcement mortar is mixed with the specified amount of clean water using a paddle mixer until a workable consistency is achieved. The mortar can also be processed with all common plastering machines and silo mixing pumps, e.g., EMP. For applying the adhesive mortar to the insulation boards, a special adhesive gun can be used. br Adhesive application br The webertherm insulation boards are coated in a frame shape and with two or three vertical strips of adhesive mortar. The mortar is to be distributed so that at least 50% of the surface is bonded to the substrate after pressing. br On sufficiently even substrates and when using the webertherm speedy and express insulation boards, the mortar can also be sprayed onto the substrate machine-wise in a wavy pattern, covering at least 50%. The insulation boards are pressed immediately afterward into the mortar. The webertherm insulation boards can also be fully coated with adhesive. br Reinforcement br The mortar is applied in a thickness of approximately 5 to 8 mm onto the insulation boards and troweled flat. br Subsequently, the reinforcement fabric, roughly webertherm 310, is embedded in the reinforcement mortar in straight or horizontal strips without folds using a trowel or float. The surface is roughened depending on the type of top coat, e.g., for decorative textured plaster or only roughened. br Coating of plasters br The mortar is applied to cleaned or appropriately pretreated plaster surfaces up to a maximum of 10 mm and troweled flat. If cracks are present in the substrate, the reinforcement fabric, roughly webertherm 310, is embedded in the reinforcement mortar in straight or horizontal strips without folds. br For thick-layer top coats, e.g., decorative textured plaster, the reinforcement mortar is roughened after setting with a stiff broom; for other top coats, it is roughened.
