Reliably seal the façade with B.T. innovation
Regardless of whether it is a new building with façade waterproofing or a repair: If the rain penetrates from the outside through the walls into the interior, then quick action is required. For homeowners or flat owners, this can have serious consequences such as unpleasant odours and mould growth. In existing houses, the outer façade should first be checked to find the weak points and seal them professionally. BT innovation offers you several products for sealing facades for new construction and repair.
BT waterproofing products are ideal for this purpose:
- Repair leaks and damaged areas in the façade of existing and new buildings
- Seal joints and cracks in masonry and exterior plaster facades
This makes facade sealing and repairing cracks in the masonry quick and easy.
BT solutions for sealing your exterior façade
Sealing the exterior façade of a house, garage or garden shed can usually be done yourself. Exterior facades are permanently exposed to all kinds of weather and environmental stresses. This means not only rain, hail and storms, but also changing temperatures with major component and joint movements, as well as a lot of UV radiation. In the case of joint sealants with low movement absorption but large joint movements, the sealant itself can crack or tear away from the flanks. But UV light, hail and storms can also cause porous spots and small cracks to appear on the façade, where dirt and moisture penetrate and cause damage. When choosing the material you want to use, you should therefore make sure that it is waterproof, elastic as well as UV-resistant.
Causes of leaks
In new buildings or existing buildings, missing or improperly planned or poorly executed waterproofing measures can lead to leaks. Salts and moisture in particular regularly cause structural damage. An equally common cause of damp walls is the fact that living rooms and basements are not ventilated enough. In order to complete the repair successfully, the following rule applies: First, the cause must be tackled and then the damage caused must be repaired.
Repairing individual spots and joints
As a rule, it is not the entire façade of existing buildings that is leaking. Large-scale sealing is therefore not absolutely necessary. Older façades in particular, which have been exposed to the weather for a long time, show damage over time. Often it is joints that peel off over time or connections that have not been professionally sealed. In these cases, you can target these spots and save yourself the time and money for surface waterproofing.
InnoElast® – Effective sealing of joints and cracks in facades
B.T. innovation GmbH offers InnoElast® Type 1 and InnoElast® Type 2 facade sealants in accordance with DIN EN 15651-1 for professional facade sealing (with CE marking). If larger joint movements are expected, then it is recommended to use InnoElast® Type 1 with 25% movement absorption. For smaller joint movements of up to 10%, but greater water pressure or higher temperatures, the InnoElast® Type 2 should be used. Both products are filled into the joints as a paste and harden there to form a rubber-like seal. When applying, make sure that the joint edges are clean. For further information, please refer to our technical data sheets of the products.
Advantages of InnoElast® Type 1
- Sealing of cellars, floors, roofs, windows, doors, facades, sidewalks, structural joints
- Suitable for substrates made of steel, aluminum, stone, wood or concrete
- Processing from -3°C, even on damp substrates and always without primer
- Permanently elastic (up to 25% movement absorption)
- Weather and UV resistant, solvent-free and low shrinkage
Advantages of InnoElast® Type 2
- Sealing of cellars, floors, roofs, windows, doors, facades and structural joints
- High resistance to chemicals, weathering and UV radiation, solvent-free and low shrinkage
- Suitable for substrates made of steel, aluminum, stone, wood or concrete
- Processing from -3°C, even on damp substrates and always without primer
- Permanently elastic and pressure waterproof up to 0,48 bar (4,8 m water column)
Application:
Using a tubular bag gun, InnoElast® Type 1 or Type 2 is applied to a clean substrate and then cures effectively. The skin formation time is between 2-3 hours (type 1) and 15 minutes (type 2) at a room temperature of 23°C and humidity of 50%, the curing time is 3mm in 24 hours. A primer is not required beforehand. However, it is recommended to insert a joint filler cord and tape the edges. Pressing and smoothing creates a strong bond with the joint edges.

You should pay attention to
For do-it-yourselfers and professionals, it is advisable to always keep an eye on the weather conditions. A dry and quiet environment is an advantage when working on the façade, but is not absolutely necessary. The InnoElast® products from B.T. innovation enable sealing / repair even in poor weather conditions. The surfaces can be matt damp for a durable seal, but must not have a visible film of water.
An essential prerequisite is that the substrate must be free of dust, oils and greases before applying the waterproofing material. The material hardens faster at high air temperatures and high humidity.
Not every façade looks the same in terms of colour. The InnoElast® products are paint-compatible, i.e. they can be painted over with common facade paints. But colour-matched sealing materials are also available. Whether older masonry, new exterior plaster facades or terraces – they should all be well protected because they are permanently exposed to movement. Therefore, a regular check of the façade waterproofing makes sense.
