Claytec, clay adhesive and reinforcing mortar, bag 25 kg
Clay adhesive and reinforcing mortar for reinforcing layers on clay boards as well as wood fibre finishing and interior insulation boards. Clay adhesive and reinforcing mortar consists of clay and cellulose. This guarantees optimum workability, even with thin coats. With a compressive strength of 3.9 MPa, which is new for clay mortar, and an adhesive strength of 0.85 MPa, clay bonding and reinforcing mortar guarantees the strength of the entire construction. It is the basis for fine Claytec clay finishing plasters and YOSIMA. With good preparatory work, it can also be simply painted with the Clayfix clay coating system.Data sheet Application videoHow to useAdhesive and bonding mortar as a dry, fine-grained ready-mix for bonding lightweight building and interior insulation boards to various substrates, as a reinforcing mortar on clay building boards, clay-hemp boards, wood fibre insulation and wood fibre finishing boards and mineral foam boards.CompositionSand up to 1.0 mm, clay and loam, talc, perlite, plant fibres and cellulose.Delivery form, yield25 kg bags (makes 17 litres of mortar for 5 m2), 48 bags/pal.StorageCan be stored in a cool, dry place indefinitely.Mortar preparationThe 25 kg dry mix is gradually stirred into 8-9 litres of clean water using a drill (≥ 800 watts) or mixer and stirring paddle (Ø 125 mm). The amount of water added is slightly less for bonding mortar. Working consistency paste-like according to the desired application with a notched trowel or spatula.Work well again after 30 minutes resting time. The mortar is now ready to use.Plaster baseThe substrate must be stable, frost-free, dry, clean, free of salt, sufficiently rough and absorbent. Levelling coats of clay plaster mortar must be completely dry.The surface must be as level as necessary for the bonding described below. Small unevenness (small individual areas up to 5 cm in diameter and 3 mm deep) can be levelled with the adhesive. Larger imperfections must be filled with a suitable mortar and left to dry.ApplicationThe adhesive is applied to the back of the panels to be bonded using a notched trowel or spatula (8-10 mm notches). A thin layer of adhesive should be applied to the entire surface, including the grooves. The first board is applied immediately and pressed firmly onto the substrate; contact must be ensured over the entire surface.Uneven masonry and plaster surfaces are slightly pre-wetted and roughly levelled. The back-coated boards (see above) are pressed in wet-on-wet.Boards can be additionally mechanically fixed as required, e.g. on sloping ceilings and roofs, see corresponding board product sheets or worksheets.As a bonding filler for thick-layer plasters on insulation boards (e.g. for wall surface heating) and similar applications, the slightly stiffer mortar is applied in the same way using a notched trowel or spatula.For reinforcement layers, the 3 mm thick mortar is applied. It can also be sprayed on with a plastering machine; resting times are not necessary for this application. Reinforcement mesh is worked into the surface of the layer while it is still wet.HardeningThe curing time is 24-72 hours, depending on the drying possibilities and absorbency of the substrate. With additional mechanical panel fixing and subsequent thin-layer coating, work can continue immediately.Work samplesAdhesion to the substrate must always be checked with the respective board to be fixed using a sufficiently large working sample. Complaints not resulting from mixing errors at the factory are excluded.

Weight approx. 7 kg per square metre.Selected reed quality and high-quality strong binding made of 1.8 mm thick galvanised wire, the staples are made of 1.3 mm thick stainless steel wire.Reed insulation panels are fixed to masonry or other mineral substrates with insulation plugs. Requires approx. 7 pieces per m².The panels can also be screwed to wooden structures.Thermal insulation made of reedData sheet Video Video 2 Processing instructionsInsulating with natureMore and more environmentally conscious building owners are opting for natural insulation materials in order to make their contribution to climate protection and at the same time create a cosy and healthy indoor climate. For this reason, insulation materials made from renewable raw materials have been increasingly used again in recent years, both in new builds and renovations.What exactly are renewable raw materials?Renewable raw materials (NaWaRo) such as reed, wood, flax, cork, hemp, sheep's wool, etc. come from nature and are therefore ecological "by tradition". They are produced in an environmentally friendly and resource-saving way and require little primary energy.Zero chemicals, zero pollutants, great climateInsulation materials made from renewable raw materials (NaWaRo) are largely free of chemicals and pollutants. They compensate for fluctuations in temperature and humidity better than mineral insulating materials and offer excellent soundproofing properties in addition to thermal insulation. And they can also provide a "cool climate" inside the house in summer: plants store heat wonderfully and thus prevent rooms from heating up, which is a particularly beneficial effect under sloping roofs. Natural insulating materials are superior to their mineral competitors because they are better at equalising fluctuating temperatures and humidity while maintaining the same good insulating performance.Ecologically insulated with reedNaturally from tradition: reed is probably the oldest building material for full thermal insulation and was already used in the Neolithic Age to insulate houses against the cold. In historic buildings, there are many plasters with reed mats as supports that have lasted for several centuries. Reed is the most natural building material that environmentally conscious homeowners can think of and scores with an outstanding carbon footprint: it ranges from low energy consumption during production (the reed is only cut, pressed together and bound with stainless steel wires) to material-free recycling. This makes reed a pollutant-free alternative to rigid foam panels made of polystyrene and polyurethane, which are made from crude oil and require a great deal of energy during production. As a renewable raw material (NaWaRo), reed has special properties from its original natural habitat: as an aquatic plant, reed is extremely resistant to rotting. The high silicate content in the reeds makes them rot-proof, prevents swelling and shrinkage and ensures that reeds are difficult to ignite in plaster. Important for owners of old buildings: The breathable material, which also ensures a pleasant indoor climate and excellent sound insulation, moulds perfectly to walls that are not completely flat. Because the reeds can be moved within themselves, movements in the substrate can be easily compensated for.The natural insulating material reed is extremely versatile. It is suitable, for example, asInterior insulation of half-timbered and other housesfor external insulation as part of thermal insulation systemsas effective roof insulation on/under and between the raftersas ceiling and floor insulation Reed insulation boards are also very easy to work with: Builders can simply cut them to size themselves using a table saw or hand-held circular saw.Reed can also save financial resources: In terms of purchasing materials, reed insulation is cheaper than cork, mineral foam, wood fibre or vacuum insulation. However, the time required for installation is 6-15 minutes longer per square metre.
