Protech Sil P - Therm
Protech Sil P - Therm is a paint suitable for any type of mineral substrate, such as old and new plasters, synthetic plasters, sandstone walls, etc. For old emulsion paints, remove non-adherent parts, remove any impurities, repair any cracks or crevices and then consolidate everything with Protech Fix AC - Therm, a silicon water repellent fixative primer, also suitable for highly alkaline substrates.
Protech Sil P - Therm has excellent covering power: class 1 according to EN 13300 for a yield of 6/7 m2/l.
Fields of application
In addition to the painting of external facades and internal environments, Protech Sil P-THERM has been designed especially 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. The great advantage of this paint is that it can be applied both on mineral (inorganic) supports and on previously treated supports with emulsion-based paints, creating a physical adhesion, with extremely microporous films. The particular chemical structure of the silicone binder produces a film resistant to light and atmospheric agents that is not destroyed even by microorganisms.
Allowed supports
Plasters
Concrete
Cement-based or lime-based mortars
Prefabricated concrete
Drywall
Plaster (gypsum)
Fiber-cement
Preparation of supports
For old emulsion paints, remove non-adherent parts, remove any impurities, repair any cracks or crevices and then consolidate everything with Protech Fix AC - Therm, a silicon water repellent fixative primer, also suitable for highly alkaline substrates.
SUPPORTS ALREADY PAINTED WITH SILICATE PAINT
Remove any stains and proceed with painting with the siloxane paint. (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
On old supports, remove the old paint by brushing, fill in any holes or imperfections in the wall with a suitable filler, proceed with fixing with siloxane impregnating agent diluted 20 to 60% with water depending on the absorption of the support.
Mode of use
DILUTION (in volume with potable water)
1st COAT:

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. Never operate at temperatures below + 5ยฐC. Rainy weather, excessive atmospheric humidity and temperatures below + 8ยฐC, 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. For storage store in tightly closed containers and protect from frost.
