Which bonding primer is necessary for a restoration plaster?
The splatterdash mortar THERMOPAL-SP is used as a bonding primer for restoration plasters THERMOPAL-SR24, THERMOPAL-SR44, THERMOPAL-GP11 as well as THERMOPAL-ASP45. As a rule this is applied beneath restoration plasters as half cover as nodules (coverage rate < 50%).
The splatterdash coat is only applied as full cover beneath restoration plasters if the substrate was previously coated with e.g. a waterproofing slurry.
The mix water for THERMOPAL-SP can be modified with the hardening and bonding agent ASOPLAST-MZ for very absorbent or very weakly absorbent substrates.
THERMOPAL-SP can also be used as a splatterdash coat for conventional cement or lime-cement mortars.
Why are restoration plasters used?
Restoration plasters are used for producing diffusion permeable and dry plaster surfaces onto damp and/or salt laden internal and external walls.
Restoration plasters have a relatively high air pocket content in contrast to other plasters, which is required to allow structurally damaging salts to crystallize out in the plaster without damaging the plaster.
What differences are there with restoration plasters?
The SCHOMBURG restoration plasters THERMOPAL-GP11, THERMOPAL-SR24 and THERMOPAL-SR44 are WTA certified products (WTA data sheet 2-9-04/D).
Restoration plasters to WTA guidelines have hydrophobic properties and increased water vapour transmission whilst at the same time having reduced capillary conductivity.
THERMOPAL-SR44 is characterised by an extremely low consumption (consumption: 7.5 kg/m²/cm).
THERMOPAL-SR24 possesses the advantage of a rapid cure which makes the early post-treatment of the plaster surface possible (e.g. rubbing down or using a grid float).
The areas of application remain basically the same for SCHOMBURG restoration plasters.
At which thickness must restoration plasters be applied?
The minimum thickness of THERMOPAL restoration plasters is 20 mm dependent on the salt levels in the substrate. This can be applied in one operation.
With high to medium levels of salting, apply the restoration plaster in two layers from a minimum thickness between 25 and max. 40 mm.
From experience, allow a waiting time of one day per millimetre in-between plaster layers.
How can restoration plasters have coloured designs?
Use highly vapour permeable paints such as e.g. silcate paints on restoration plasters in order not to impair the effectiveness of the restoration plaster system. This is also applicable for further build-up such as e.g. fine or decorative plasters.
As renovated areas with restoration plasters are frequently coated with a white paint, SCHOMBURG also offers THERMOPAL-SR44 in white, whereby the usual paint can be omitted.
Can I also apply THERMOPAL-SR44 (white or grey) mechanically.
Yes e.g. with the PFT G4. The necessary features can be extracted from the equipment schedule THERMOPAL-SR44.
