Protech Sil I - Therm
Protech Sil I - Therm designed above all for buildings and monuments subject to the protection of the Ministry of Cultural Heritage. The binder based on an emulsion of silicones has allowed to develop a microporous filter impermeable to heavy rain, and at the same time permeable to the diffusion of water vapour. Thermal insulation coating that allows the realization of a thermal insulation with the obvious advantages of recovering the thermal mass from the walls and eliminating bridges and thermal changes of the buildings. Due to its high degree of insulation and transpiration, it is widely used to radically solve mould problems, through the synergistic action of fungicide and thermal insulation. It is composed of a water-dilutable silicone resin, acrylic dispersion, with controlled grain size marble grit, fillers, 3M Glass Bubbles, sanitizing additives and pigments, in a content that guarantees the fulfilment of physical parameters such as: permeability, water repellency, CO2 diffusion, etc.
Fields of application
Suitable for any type of mineral support, ideal especially on walls where the growth of mould and algae represents a serious problem. Due to its low thermal conductivity, it is particularly suitable for solving problems of mould and algae on walls exposed to areas of shade and high humidity.
Allowed supports
Plasters
Concrete
Cement-based or lime-based mortars
Prefabricated concrete
Fiber-cement
Preparation of supports
SUPPORTS ALREADY PAINTED WITH SILOXANIC PAINT
Remove any stains and proceed with painting with the siloxane coating (it is always recommended to apply a coat of siloxane impregnating agent).
NEW SUPPORTS
Apply a coat of siloxane acrylic fixative diluted from 20 to 60% with water depending on the absorption of the support.
OLD SUPPORTS ATTACKED BY MOLDS
Clean the wall from mould and algae with a steam cleaner, disinfect with Consilex Muffa Cleaner and Consilex Muffa Remover (sanitizer) after a few hours, when the microorganisms have neutralized proceed with the application of a coat of Protech Fix AC - Therm diluted from 20 to 50 % with water. Once dry, proceed with the application of Protech Sil I - Therm.
Mode of use
The product is ready to use if necessary add a little water and stir slowly. Apply a coating layer with a stainless steel trowel with a thickness equal to that of the granules it contains. Pass again with a cutting spatula to remove any excess material. After light drying, pass over with a plastic trowel with rotary movements to compact, even out and achieve the full plaster effect.
On large surfaces, it is recommended to apply the product of the same lot and proceed always wet on wet to avoid signs of resumption.

Storage and conservation
Protect from freezing.
Warnings
Never operate at temperatures below + 5°C. Rainy weather, excessive atmospheric humidity and temperatures below + 8°C, can considerably compromise drying with the possibility of rainwater washout even after several days. In these situations, it is advisable to protect the facades from unpredictable showers, in order not to jeopardize the success of the work.
